UK Power Networks trials Thermify's HeatHub boilers, swapping gas flames for clustered compute

Reusing heat from servers has gained momentum recent years, but UK Power Networks (UKPN) is taking an unusual approach: installing mini datacenters powered by Raspberry Pi hardware in customers homes to provide heating for families struggling with energy costs.

UKPN, which manages the "last mile" of cables and substations delivering electricity from the National Grid to customers in the South East of England, is piloting the project as part of its SHIELD (Smart Heat and Intelligent Energy in Low-income Districts) program.

This will equip participating households with solar and battery systems, while one-third will also receive the "HeatHub" system - a compact datacenter roughly the size of a large heat pump that replaces traditional gas boilers. [...]

Nothing is free. Your equipment depreciates, so you need to account for that. Might be worthwhile if you have solar panels, a battery and use dynamic pricing. So you can charge the battery with solar and when electricity costs next to nothing, so you can run the equipment for heating of the battery when you get home in the afternoon which is usually when electricity prices go up. But end of the day it’s cheaper to just burn gas or use a heat pump if you just want to heat your home. And the heat a GPU array generates is probably not enough. The more efficient the GPU is with mining the less heat it generates, so the heat output per dollar input goes down. Not to mention the cost of a single GPU or ASIC miner.
