In the past, natural gas hot water heaters were the choice for energy conscious consumers. They were less expensive in terms of monthly energy costs. However, now heat pump electric hot water heaters, also called hybrid hot water heaters, are changing that.
The hybrid hot water heater has several advantages over a gas hot water heater.
Does not need an 18" High Platform to be installed in a garage
No flame burning in the unit - safer
Lower Energy Costs $151 per year estimated in warmer climates
Blows cool air and dehumidifies the space
Quieter - A power vent gas hot water heater is loud when running, sounds like a small jet engine. The Hybrid has a fan that is only 51db about like a refrigerator. A power vent gas is 74 db.
No exhaust fumes that exit the unit outside your home. Again, safer and not risk of CO2 poisoning.
Not ideal for cold climates - Would require extra ducting to vent cold air outside.
Needs extra lines for condensate drains
Requires 220v service
Here is an example of a switch from a natual gas power vented hot water heater to an electric hybrid hot water heater. This water heater is installed in Evergrene subdivision Palm Beach Gardens, Florida. The owner is very happy with the switch. They enjoy the little air conditioning boost in their garage and the decrease in sound levels.
