Replaced my electric resistance water heater with heat pump, dramatic reduction in energy usage
(lemmy.world)
I recently installed an Emporia Vue with monitoring for the individual circuit my water heater is on. It captured the very significant difference in energy usage from replacing resistive heat with heat pump.
I managed to convince my mom to invest in a heat pump after showing her the costs for keeping my apartment at a steady 22c through all of February this year.
My heat pump had cost me ~8eur to run all through February, for about a 40 square meter living room, kitchen, and hallway.
In the same time period, the electric resistive heater in my bedroom, set to 15c had cost me 22eur to run. My bedroom is about 11 square meters. 1/4th the area, a significantly lower set temperature, and 3 times the cost.
And no, there isn't a significant bigger heat droop or something for my bedroom, same type of walls, insulation, window, etc.
