Nest cracks out cheaper spin of its thermostat

Heat pumps still mean you use electricity to heat.... and that's just not the cheapest (and most efficient) way. Unless the electricity is more or less for free (like water running down the hills in a rainy country, like Norway) - and even then there is an environmental impact of the power generation setup which you might want to reduce.

If you use heat generated by burning stuff to generate electricity and then use the electricity to heat that's less efficient than using the heat to, well, heat. And then there is also the district heating mentioned by somebody else where heat is just a byproduct and otherwise would be used to heat the local river (or evaporate massive amounts of water, or both).

I think we pay like 150€ or so annually for heating and warm water. No way a Nest makes sense economically.
