The most energy-efficient water heater available. Uses 60% less electricity than standard electric units. Florida's warm climate makes heat pumps run at peak efficiency year round.
A heat pump water heater does not generate heat directly like a standard electric element. Instead, it uses a compressor and refrigerant system — similar to an air conditioner running in reverse — to pull heat from the surrounding air and transfer it into the water tank. This process uses roughly 60 percent less electricity than heating water with resistance elements.
Think of it this way: a standard electric water heater converts electricity directly into heat, which is inherently inefficient. A heat pump moves existing heat from one place to another, which takes far less energy. For every unit of electricity consumed, a heat pump water heater produces 2 to 3 units of heat energy.
Heat pump water heaters need warm ambient air to operate efficiently. They work best when the surrounding air temperature stays above 40 degrees. In Sarasota, the temperature drops below 40 degrees on fewer than 10 days per year. That means your heat pump water heater operates at peak efficiency virtually every day. In northern states, the unit has to fall back to standard electric resistance heating during cold months, which eliminates most of the energy savings. In Florida, that almost never happens.
There is an additional benefit: while the heat pump extracts heat from the air to warm the water, it also produces cool, dehumidified air as a byproduct. In a Florida garage or utility room, this is a genuine side benefit — a small amount of free air conditioning and dehumidification in a space that is typically hot and humid.
Heat pump water heaters need more clearance than standard tanks — typically about 1,000 cubic feet of air space around the unit, roughly the size of a 10 by 10 foot room with an 8-foot ceiling. Most Florida garages meet this requirement easily. They also need a condensate drain since the dehumidification process produces water. They run on a standard 240-volt, 30-amp circuit, the same as a conventional electric water heater, so electrical upgrades are usually not needed when replacing an existing electric unit.
A heat pump water heater typically costs $1,500 to $2,500 more than a standard electric tank of the same size. However, the energy savings in Florida average $300 to $500 per year, which means the extra cost is recovered in 3 to 5 years. After that, you are saving money every month for the remaining 10 to 15 years of the unit's life. There are also federal tax credits available for heat pump water heater installations that can reduce the net cost further.
We install Rheem ProTerra, AO Smith Voltex, Bradford White AeroTherm, and other leading heat pump water heater models. Each has different features — the Rheem ProTerra offers smart home connectivity and a built-in leak detection system, while the AO Smith Voltex has one of the highest efficiency ratings in its class. We recommend the best fit based on your household size, hot water demand, and budget.
