I’ve been using retroarch with the Genesis Plus GX core, and that seems to work well and is open source. Not everyone loves retroarch, but I’ve moved to it so I can use some of the more interesting HDR 4k CRT shaders

We don’t tend to use air/air heat pump systems in the UK, even for new builds, always air/water.

Because of lower water temperature output of heat pumps compared to the gas boilers they replace, usually you need to increase the size of radiators to be able to achieve a room temperature change in a reasonable time. What is being referred to as efficiently, is actually just a measure of performance of the radiator, not actual energy efficiency.

Nope, it’s not. It’s in the terms of service. If you don’t like that, don’t sign the contract with them. Steal it if you want to. I’m cool with piracy, just not with the poor attempts at justification.

This is why I only carjack rental cars, it’s totally not stealing!
