We're on our second AO Smith hybrid electric (heat pump) water heater, which just failed (both within a year). The compressor continues to run, but there is no heat exchanging going on (inlet and outlet air temps are the same; garage is 55-60 F). Not only that, it's noisy and takes up valuable garage real estate. Our house is all-electric (with 400 amp service). I understand that efficiency is only 99% with a tankless electric vs. 200%+ with a heat pump unit. The incremental electric costs are not a deal breaker for me given the benefits (endless hot water, silent, low space requirements).
Who makes the best electric tankless heater? We would need ~25kW.
