What is a good standby loss for water heaters?

For electric water heaters, the EF is typically around 0.9, and for natural gas water heaters it’s around 0.6. By going to a tankless gas water heater, you can reduce the standby losses greatly and get that up to about 0.82 or so.

How do I calculate my standby water heater?

Standby efficiency is the water heater’s ability to contain heat in the tank. A minimum of heat loss per hour is desired. Basic formula: temperature change per hour = [BTU/H loss per square foot of tank surface] divided by [“R” value], shows that more insulation is better.

Can a 30A circuit breaker be used on a 240V water heater?

This way, a 30A circuit breaker for over current protection is suitable in case of 5kW dual element non-continuous water heater circuit for 240V AC. The following 7kW (each heating element of 3.5kW) has the same wiring connection as above for 5kW thermostat wiring despite a 20A single way switch has been used in 230V AC for ON/OFF operation.
