Huh?, thought that was pretty obvious from the OP - 33kW per day. Or
approx 1.4kW/hr, also what the OP stated. Together with a low-loss
distribution system to the water heaters that the OP stated, gives
1.4kw/hr (33kw/day) heating to the house.


I think perhaps you need to brush up on your basic physics - your (and
the OP's) usage of kW makes no sense.


As previous reply - yes, needed to engage brain. Sad thing is not just
basic physics but classically trained with E&E eng through Uni. Was too
eager to jump onto a non-value-added reply. You're quite right, though,
that original units were ambiguous / wrong. The basic premise, however,
that the OP wanted to heat his mother's water by 1.4kWhr all day should
still be obvious, and the link to the American website (pah!) with the
48v heater element still addresses the OP's query. "no sense" -
agreed, the details were incorrect, however, would not require a massive
leap of faith to understand and answer OP's question.
