We got a heat pump (at last)

Posted on March 28, 2026

It was inevitable really. I’m a life-long environmentalist who got solar panels 15 years ago, an EV 11 years ago, and a battery a few years ago. I also spent my own money to madly build a 1.23MWP solar farm. Of course I was going to get a heat pump. In fact you may well have assumed I already had one. Why was I not earlier to this?

We live in a very old house. Its funny because where I live, its just considered an ‘old’ house, because there are so many here, but by most people’s standards its ludicrously old, as it was built in 1750. Living in a house like this is kinda awesome, if you like BBC costume dramas, and it certainly has a lot of ‘character’, but there are definite drawbacks. One is that it is quite cold, as the walls are single-thickness, without cavities, and the other is that you need government permission to change anything.

When heat pumps first came out, there was definitely a vibe o ‘well its cool if you have a passivehaus’ and then things migrated to be ‘its great as long as you have underfloor heating and excellent insulation’. This was still no good to us, as our floors are either suspended wood over a cellar, or brick and huge chunks of stone. Underfloor heating would never be a thing here. But then heat pumps got better and better, and we managed to (finally) get double glazing, and it actually looked like getting a heat pump might work for us.

Quotes and Grants

Luckily a neighbour of ours already had one, so we went and gawped at it, and asked questions etc. (They have a newer house). Eventually we decided to go for it, and got quotes. Oh my god the quotes. First we needed to get an ‘Energy performance certificate’ for our house, which basically means pay £100 to some freshly qualified surveyor who walks around your house and fills out a form. Like many govt programs, this was a big waste of time, because although you need the certificate, the govt dropped any limit on how efficient the house had to be before getting a grant for a heat pump. The certificate is thus just a piece of paper that gets stuck in a drawer that was pointless, but we had to do it anyway.

Why did we need it? Well because the UK government, for all its sins gives you £7,500 towards a heat pump, and that certificate process is the only string attached. So well worth it. Why did they drop the efficiency limit? Well someone in govt finally worked out that the only people getting heat pumps installed were retired middle class people who tended to live in old houses. If the efficiency limit was too strict, they wouldn’t bother, and they need ‘early-adopters’ like us to kick-start uptake of heat pumps. Getting the grant was satisfying because I have NEVER got a grant from the govt to do anything (not even the solar farm).

Anyway, grant plus paperwork in place, we got three companies to give us heat pump quotes. One was just totally useless. Another did an exhaustive heat-loss survey, but all of the numbers were blatantly just wrong. We eventually went with a third (which our neighbours used), and they were tons better. Basically they need to come measure your rooms, look at your radiators, do a ton of calculations and decide what size heat pump you need, and if you need to upgrade radiators. We were told we needed a 14KW heat pump, and no urgent radiator upgrades. In the end we doubled the size of two of them anyway, in rooms that were always cold.

We then needed ‘listed building consent’ and ‘planning permission’, and that was an epic world of stupid stupid pedantic pointless government bureaucracy bullshit I won’t bore you with, because unless your house is listed, you wont need it.

The Installation

And so it came to pass that people came and installed a heat pump. Yay. Because we had previously had an outside oil combi-boiler, our house had zero hot or cold water tanks. So we needed one of those. And luckily, it went in our cellar, which is where we put stuff like batteries etc. This was awesome as it meant taking up zero room in the house. I was impressed that the installers were not put off by having to install a hot water tank and ton of heating controls down some tiny steps in a cellar, especially as the door to the cellar is actually a secret door that works as a bookcase. Its all very scooby do.

Anyway, after a few days of fuss, we ended up with this!

And if you think ‘seriously thats a lot of tubing’ I agree with you. I had it all explained to me, but I zoned out a bit. It looks more complex than it is, and you can basically ignore it all and just use a tiny little remote thermostat gadget to control it all that looks like this:

And of course the actual heat pump got installed (which was way quicker) and the old boiler removed. It went in the exact same place and is here:

I should point out this is a BIG heat pump for a 1750s 3 bedroom detached house. If you have an average UK terraced house a heat pump would be 5-8kw. Ours is 14kw. Also worth pointing out that although the total cost for our heat pump massively exceeded the £7.5k grant, that would be VERY different for a typical smaller one, especially if you already have a hot water tank and don’t need it installed somewhere awkward.

So the heat pump was installed, and everything was great. The end.

The difficulties and the fix

But no! It was an irritating nightmare of unhappiness for a few weeks. We had major problems. Firstly it seemed like it used a TON of electricity to do NOTHING. It then seemed that it COULD generate hot water (and lots of it), or hot radiators, but never under our control. It was frustrating and disappointing and I was unhappy :(. We argued and complained a bit. We also decided to double the size of one of the two radiators in our living room. This was a good move and made a big difference, BUT what totally transformed everything was the radiator dude spotting that the ‘Hysteresis’ was set wrong. This is a setting that determines how much the heat pump lets temperatures diverge from the thermostat before switching. Heat pumps do NOT like to be constantly going on and off. Insanely ours was set to 20 degrees, when it should have been 8 or even less. So our heat pump would be told to get the radiators to say 50 degrees, do it, then switch off and not care about switching back until they were 40. The same happened with hot water. It also controls how much you can overshoot, so a Hysteresis of 20 means radiators oscillated from 40 to 60.

In practice what this meant is that it all felt RANDOM. Sometimes radiators were super hot, often seemingly cold. Ditto hot water. It felt like the whole system was under someone else’s control. It sucked. We had heat-pump-purchase regret. But actually the minute that setting got changed, everything then worked perfectly, and we are very happy. The house is warmer than ever.

Its worth pointing out we had several conversations with the installer, lots of emails and frustration before eventually it was spotted that this was wrong. We are so glad that we persevered to make sure it was set up correctly, instead of just being grumpy and mumbling that ‘heat pumps suck’ which I think some people do when they have this problem. Check your settings!

The conclusions

So… was it a good idea? Well actually YES. If you read my blog you know I would do it anyway. Its about the environment for me, not money. I HATED buying thousands of litres of oil to heat our house, and wanted to remove my last direct usage of fossil fuels. But actually now its all set up right and we have the right radiators, its pretty good. And our timing was comically good. Not only was our oil tank 99% empty when they took the old boiler away (luck!), but just as we are settling in to our oil-free lifestyle, the Iran war starts and the price of heating oil has more than DOUBLED. Our electricity bill is definitely a lot higher, but then we now have zero oil bill. Plus we had the heat pump fitted in winter, so it was always going to be the most expensive time to assess how much power we now used.

So, my tips for anybody considering it? Firstly I would say shop-around and read reviews. Some installers are good, some not. Same as anything. Ask neighbours who have had one fitted for references. Secondly, take any recommendations about new radiators seriously. We were a bit flippant. We should have got that radiator fitted at the same time. Thirdly, Make sure its set up right. They are COMPLEX and you need it set up right for your lifestyle and your home.

But generally, I am very happy. Out of solar, batteries, EV and heat pump, this was the most disruptive and hardest upgrade. However if you are in the UK don’t delay. That govt £7,500 grant will NOT be around forever. Take advantage of it. Oh and if you are thinking of getting solar or a battery, GET LOTS. We have gone from smugness about our 4.1kwp solar and 19kwh batteries to ‘Balls, I wish we had more…’. A heat pump does push up how much electricity you use, so generating more and storing more off-peak power will be well worth it.

Auto-balancing and load-testing Ridiculous Space Battles

Posted on March 21, 2026

Its been a while since I blogged… Anyway I have not been completely idle. As well as booking a long-desired holiday to CHINA (oh yes!) I have still been working on this weird project that I cannot decide if its a retirement hobby or a proper serious game launch, and that would be my pretentious re-imagining of Gratuitous Space Battles, which I am appropriately calling ‘Ridiculous Space Battles’.

The game is very playable right now. It has a ton of content, and it runs great, and it looks fab. But it does not have data for the campaign games, and does not have the challenge system coded into it yet. I might at some point decide to put the challenge system off for a bit, and release it with skirmish and campaign games into Early Access. I really do keep changing my mind on that. This game has been very cheap to make, and I am under no pressure to release, so to be honest it feels kinda weird being able to do anything I like with it!

Anyway, something I have always wanted for my games was a pre-release debug build functionality to have them run hundreds or thousands of games and automatically provide data that would let me balance the initial stats before actual humans start to play it. Now if you are a relatively new developer, its easy to just sling out lines like “Yeah just code a headless mode that randomly designs ships and fleets and have them fight each other a million times to collect stats”. This is the sort of thing swaggering indie devs throw out in a reddit thread as advice, as though that single sentence contains all the required skill, code and effort.

Its not that simple.

Now if you have a much simpler ‘problem-space’, then it gets massively easier, but just the process of coding random ship designs and random fleet deployments is a major engineering effort in itself. Getting the game to be able to put together a ‘legal’ in game-terms design isn’t too tricky, but ensuring it produces sensible designs is another things entirely. There is nothing to stop the entire deployed fleet consisting of a hundred ships that only have anti missile defence weapons and zero offensive capability, for example. That would be a valid fleet design, but useless for auto-balancing. Worse, it would imply in the stats that missiles are useless, without the caveat of ‘yup but that strategy can never win a battle’.

Its a massive minefield of issues like this, an frankly I have not addressed any of them yet. My current code designs each ship in a fleet individually right now, so the chances are such anomalies would be highly unlikely. However, the point stands that a ‘random’ fleet design is not ideal. And thats before we start placing those ships in formations, and assigning orders to them based on their designs. I’ve done a bunch of wok on that, but its still not ideal.

The actual easy bit was the stats collection and amalgamation into a nice spreadsheet at the end. My game is very stats-based (its an auto-battler after all), so the code to track all those stats was already in game. What took a bit longer was the wrapper code to run through a battle with a random fleet, record stats, and then do the next battle. This *sounds* easy, but when a game has been designed on the basis of the user clicking buttons, circumventing that without errors can be buggy. I didn’t just simulate mouse clicks because I needed to totally skip the deployment UI for each battle. Otherwise I am flushing a ton of textures and loading a whole pointless UI between every battle, slowing down the auto-run process.

The real delay in this stuff has been two-fold. I need to code some sort of basic genetic algorithm for ship design, and I also encountered loads of bugs. Lets do the bugs first. Its easy to think ‘dude, you shouldn’t have bugs in your code’, but harder to make that a reality when you have a game as complex as RSB. There are over 720 source files for the game and the same amount again for the engine, and the code is fiendishly complex. Plus the actual GAME is fiendishly complex. For example, I encountered a crash bug while typing this (The game was churning auto-balance in the background). It was a crash bug where the game lost focus, then recovered focus (I had moved to another window), and it crashed in the shader for Target Painter weapons.

You might think ‘what a noob, you obviously dont re-init your shaders’, but nope, I do. This is obviously something specific to THAT shader. I have tested the game a lot, but apparently never alt-tabbed away exactly when the game was drawing a target-painting effect. Given how many different systems and visual effects the game has, its no wonder I have not churned through all the possibilities yet. This is one of the major benefits of writing this autobalance code. I am soak-testing my game, running thousands of battles and trying every permutation possible, and it throws up a ton of asserts and warnings and crashes, all in obscure and exciting places. I DO test new features when they are added, but testing them in every permutation of battle is impossible. I’d need 50 people working in QA.

So the last aspect of all this is genetic algorithms. I intend to try a bit of this but no go mad. Right now, I can only tell if ‘fast missiles’ are overpowered by looking at the amount of damage they do, over 100 battles, compared to their cost and weapon module size. If they DO look a bit overpowered, then maybe they should be selected more, to assess whether they are clearly a super-weapon, or if thy just happened to always get matched against fleets that had poor missile defence. Perhaps I need a system that takes the top ten weapons from the previous 100 games and biases towards them so I can concentrate on collecting data for them. Perhaps also do the same with the BOTTOM ten weapons so I can see if they were just badly represented due to random match-up.

And of course all of this is ignoring non-weapon modules. I should probably test the ‘survival rate’ or ‘survival time’ of ships with each armour and shield module or other defensive module like a decoy projector or cloaking device. Maybe these are hugely overpowered? I have not even begun to look at that yet.

One piece of excellent news though. My game is VERY good at pruning its memory usage and definitely has no leaks. I’m watching the area chart in the visual studio debug view as I type and its currently using 234MB (lolz) and rarely goes above 400MB in big battles. This is a vast improvement on my other games, or early builds of RSB that were leaky.

So there you go, I AM still coding, but not in a hurry, and I hope the end result is worth it :D. Don’t forget to add RSB to your steam wishlist if the game sounds interesting to you!

Is AI capable of reversing social media’s attention destruction?

Posted on March 4, 2026

This evening I spent some time talking to the latest version of Claude about investment decisions, and the rationale behind various stock price movements. I also spent a bit of time browsing a bunch of of discord channels on servers I sometimes hang out on. I found the difference in information delivery to be extremely jarring.

I also, for some reason, occasionally spend time on the reddit ‘wallstbets’. It’s 95% bullshit, and 5% actual insight and analysis. As a result, I’m used to seeing a lot of typical 2026 one-liners, memes, in-jokes and random emojis and pop culture references, inter-spaersed with the odd bit of insightful financial analysis and modelling.

I do generally find most internet forums, reddits, social media threads and discords to be… kinda dumb and juvenile. Sometimes its what I want. An endless stream of star trek memes is exactly what I need sometimes, but in general I am more interested in in-depth analysis, and specifically, for analysis that presumes I am a) an adult and b) have an attention span. Any website that ‘warns’ me how many minutes it takes to read an article is an instant red flag for me. I am not a child, and am capable of sometimes reading entire books! Your article can be multiple pages. I will not expire out of frustration.

Enter AI

AI is perfect for me. I can ask claude a question about cocoa prices and it will respond with analysis. There will be no jokes, zingers, one-liners, memes or attempts to entertain me. If I then want information about the Strait of Hormuz and its impact on Korean financial firms, then it will provide me with detailed analysis of that too. If I want to dig deeper on the valuation model for specific Korean firms, it will do so. If I have supplementary questions about the leadership structure of that firm, it will research I and answer. If I ask for a comparison table of that firm with western firms in the same industry, or historical comparisons, it can do that too. In fact, if I want to spend the next 48 hours doing nothing but detailed research into the Korean banking industry, then Claude will provide, in as much depth as I can possibly stand.

The contrast with social media is staggering. On social media, you have maybe 128 characters to provide content. Thats trivial. On video sharing sites, you basically have a few seconds. It’s entertainment for the chronically distracted. A constant stream of unrelated trivial bullshit for people who have regressed to the point where even this paragraph would be considered an essay.

Until AI came along, I found the web just frustrating, distressing, pointless and deteriorating. It does not matter how many times you click on ‘show less of this’ on youtube shorts or facebook reels. Your opinion is not important. The social media giants have decreed that all media is SHORT, and if your attention span is longer than ‘BLAM’, then you are obviously a freak and your opinion does not count.

But now, people who actually want to read, or research have a new best friend. LLMs have no adverts (yet), no distractions, no memes, no emojis, no jokes, no one-liners, no clickbait headlines, no bullshit. It’s like wikipedia in human form. You can become as informed as you like, on any topic, in huge depth, any time, for a trivial subscription cost.

When I talk to Claude about investing, it’s MASSIVELY better than reading ANY financial news or analysis sites. Even the premium ones you pay subscriptions for. I ignore absolutely all ‘news’ articles about stocks, and go straight to Claude. I can actually ask questions and seek clarifications, and I get them, without a shit-ton of ‘editorial opinion’ or sponsored links. Its amazing. And as a result, my effectiveness as an investor is way higher.

Duplicate this to absolutely any field. You have people who it seems to me have just frankly ‘given up’ and regressed into the child-like dopamine hits of nothing but social media doom-scrolling (or happy-scrolling, just ingesting a thousand feel-good videos of cute animals is equally brain-rotting), and you have other people who are able to reject that and dig deep into whatever it is they want to know about.

We seem to be becoming a society straight out of science fiction, split into factions. Some people are leveraging AI to become hyper-informed and hyper-aware. Others are stuck on social media become hyper-desensitized and hyper-distracted. Essentially we have one technology that makes people super productive, and another making them super-useless. In some cases, the same companies provide both services.

Social Media, in it’s currently ‘blipvert’ form, feels to me like a damaging disease. It’s handing out tiny droplets of dopamine in return for selling us stuff and pretending its free. But the side-effect of this is an entire generation of people with a crumbling attention span, and frankly what also appears to be crumbling IQs. I firmly believe we need hard limits on social media. The ‘endless scrolling’ mechanic is like a marketing nuclear weapon, and the privacy destroying algorithms happy to feed us endless bullshit as long as we just click-click-click until we pass out make it worse. It’s insane we let this happen. There is an alternate universe where we went direct from wikipedia to modern LLMs, without all the hate-speech-disinformation-timewasting-bullshit that is twitter and instagram. A direct line from widespread information availability to a supercharged interactive teacher.

Granted, AI can make mistakes. Hallucinations are a thing (although in my experience, way less common in premium models), but anybody who thinks the content available in general on social media and the many news websites can be entirely relied upon is deluding themselves. I personally find AI to provide way more accurate information than reddit, social media, or any news site.

I massively support efforts in the EU to force social media algorithms to change. We have an opportunity here to ‘reset’ online life so it makes us smarter, not more stupid. Lets seize it. And lets also be more willing to embrace the positives of AI. All I ever hear is the negatives, but for people who are genuinely curious about the world, AI has the potential to be an expert teacher and research team on every topic, for everyone. That sounds awesome to me.

Unexpected Solar-Powered Borehole Update!

Posted on February 24, 2026

I did not expect to be typing this so soon, but pretty soon after we agreed to fund a solar-powered borehole for fresh clean water in Cameroon… I got an update on construction with pictures today! Very welcome as I expected this to take many more months. Here is what I received today:

“Anyway, the situation in Bagham was pretty desperate because it is currently the height of the dry season in that part of the West region and SHUMAS staff reported that there wasn’t a drop of water in the village. Fortunately, the drilling rig was available and was located quite close by so work could start straight away. I am attaching a photo of the drilling rig in place and others of the work which has been started on the construction of the tower for the tank. I am sure that this project will progress quickly”

How cool is that? Here are the pics:

Digging foundations for the water tower
Making the reinforced framework for the tower
Drilling Rig
Making framework for the tower

Its very uplifting for me to see progress on stuff like this! And if you buy any of my games, you are helping me fund stuff like this, which means you are awesome :D. Especially excited to see the eventual solar panels go in etc :D.

Ridiculous Space Battles Progress

Posted on February 15, 2026

Ok so, I know this is probably not a big deal, or a new thing… but I have spent so long with this blog casually embedding youtube video links, that it took until today in 2026, and my desire to do what I can to de-couple my life as much as possible from US tech companies for me to discover that you can just natively embed an mp4 in wordpress! So anyway… I present the new race-selection screen animation effect in Ridiculous Space Battles!

and yes… before you comment, I know there is a bug with a texture changing wrongly when I scroll to the left. I’ll fix that tomorrow! I am however, pretty happy with this code, and this look. Coding stuff like this is harder than it looks, because to have everything seem smooth and crisp, you have to basically render all of those windows to an offscreen copy (with alpha) and then copy them as scaled sprites to the screen. That sounds simple, but its a lot of management, as you keep swapping render targets, and have to very smoothly transition from ‘offscreen pre-rendered sprite’ to proper rendered and full featured window.

Trust me, its a pain. It took a whole weekend. Well… it took all the hours I worked this weekend (which was not a lot TBH…). Anyway, that is one new thing that is in Ridiculous Space Battles. Another change was the re-colouring and some adjusting of the deployment screen to make it more user-friendly and less BRIGHT COLORS:

This definitely looks better. You can also see that the range indicators from my last blog post are in there with less angry colors too. The next big thing on my list is to balance the various weapons, and in fact before that, I need to code systems that really quickly run a lot of battles super-fast for me to gather stats. That will be a whole rabbit hole of code, but should be fun.

So to recap, the things left to do before early access or alpha-testing are to balance the modules, to put together the campaign fleets, to test the campaign, and to implement and test online challenges. No doubt lots of bug fixes and optimisation to do too, but I love the optimisation bit :D.
