Your water heater is cooler than yours: a heat pump water heater only drops the room 4-6 degrees in winter
A heat pump water heater moves 1600W of heat using 400W of electricity, so a summer shower is basically free air conditioning; in winter it only drops its room 4-6 degrees, because the heat needed to heat a whole tank is only enough to run the furnace for 40 minutes.
