Boilers/furnaces are ~90% efficient now. Combined electrical/heat generation can only hit 50-80% efficiency.
In theory heat pumps powered by electricity would be the most efficient option.
- kolencherry 6y agoHeat pumps don’t work particularly well below 25F. Our heat pump switched to auxiliary heat (electric resistance heating) with how cold it’s been in Texas.
- StillBored 6y agoThose are just the standard compressor/r410 systems with reversing valves. There are number of systems designed to work well below 0F. https://www.mitsubishicomfort.com/benefits/hyper-heating https://www.mitsubishicomfort.com/benefits/hyper-heating https://www.fujitsugeneral.com/us/residential/technology/xlth-low-temp-heating.html https://www.fujitsugeneral.com/us/residential/technology/xlt...
- Tossrock 6y agoThough, heat pumps lose efficiency in very cold weather, and right now it's very cold in Texas.
- 8note 6y agoTheory would require some magical fluid to do the heat transfer, and we're limited to real coolants that don't have horrid environment impacts
- benlivengood 6y agoOr geothermal heat pumps for very cold and hot environments.
