I stopped arguing with people, so I started arguing with the whole internet instead :)

I run daily comparisons between a gas boiler and a heat pump in the UK. Given that gas is cheaper than electricity, a well-installed and well-controlled gas boiler can still be che…

1. On the latest iOS, Safari, open target video (not via YouTube app) 2. From that video, open any video that’s offered under the target 3. Quickly perform the following: go back t…

Checkout NodoShop, the WiFi board version.

If your boiler supports OpenTherm then get this thermostat controller https://github.com/Alexwijn/SAT Weather comp + low load comp + PID which means your room temperature works at …

I’ve put together a small web app that, with one click, grabs five random recipes from a Google Spreadsheet, sends those URLs to ChatGPT to generate a consolidated shopping list (i…

Check out SAT Smart Autotune Thermostat https://github.com/Alexwijn/SAT Its heating curve is corrected by a PID. Room temperature precision is within 0.1 Celsius. Less gas consumpt…

The only open source implementation of OpenTherm (and EMS bus too now) that actually works (unlike commercial thermostats) and provides low load and weather compensation at the sam…

https://github.com/Alexwijn/SAT for your boiler (and thermostats)

Wait until you discover https://github.com/Alexwijn/SAT your smart autotune thermostat!

If your HVAC supports OpenTherm, check out https://github.com/Alexwijn/SAT You can have your thermostat in home assistant and make your HVAC run as efficiently as possible at the s…

Thanks! SAT (Smart Autotune Thermostat) is a free integration you can add to Home Assistant, which can work with your existing thermostat but the intention is that it replaces it a…

Here are two other boilers I found for comparison: https://emoncms.org/app/view?name=GlowWormBoiler&readkey=88a... https://emoncms.org/app/view?name=TomsBoiler&readkey=484aa31...

Thanks for your question! It’s definitely been more about passion than payback. The energy savings are there for sure, but for me, the real value has been in the learning and doing…

To calculate the cost using a UK gas price we would want to have assumed an efficiency in HHV. This is because UK gas prices are given on an HHV basis. Either convention can be use…

I agree, 25 SSI adjusted and above begins to feel too warm but that's why I set it at slightly cool instead.

Yes, that's what I noticed in the previous house, where the water tank was connected to a solar thermal panel. Solar thermal panel heats the oil inside it and the heat is exchanged…

Yes, it's between 40-60% on average. Here's a snapshot https://snapshots.raintank.io/dashboard/snapshot/OvZOk9eb6gL...

Yes, there are hybrid heat pumps that can work with gas boilers. Such system can help to reduce gas usage by up to 70%. I am considering it :)

I use something called Summer Simmer Index, which means that my target temperature takes into account indoor humidity. I feed Home Assistant RAW indoor temperature, and SAT (the in…

I see where you coming from and even if the simple calculation is not what it is in real life, it's definitely running more efficiently than it would otherwise. Also, there are oth…

I agree, most boilers, left without proper tuning are running below 90% efficiency, most likely about 80%. A 10% increase at the country level would be significant.
