A heat pump warms a home more efficiently than using the same amount of electricity for resistive heating. It can do this because it's not generating the heat from scratch; it's moving heat from outside to inside.

- OJFord 4y agoI know. It's only >100% 'efficient' if you ignore the input of 'outside heat'. That is not a normal calculation, and not really called 'efficiency'. It's desirable for multiple reasons, of course, but it's not efficiency.
- pmoleri 4y agoUnfortunately by that metric other electrical heaters tend to 0% efficiency because they are not making use of the virtually unlimited energy outside the buildings. The 400% metric let's you compare with other heaters, the 100% is kind of useless.
- OJFord 4y agoThey're not using them as an input, so.. obviously they're not included in the input/output calculation?
- xattt 4y agoA local company has developed a heat pump with a thermal energy storage system. Not sure how they do this, but I imagine there is some sort of insulated cinder blocks on a secondary loop that shuttles heat/cold to where it needs to go.
