Heat Pump Water Heaters

1. Instead of making heat, heat pump water heaters simply move it from one place to another, which is much more efficient than conventional electric water heaters, or other ways to make hot water.
2. They produce hot water 200-600% more efficiently than resistive electric tanks.
3. While they move heat, they also help dehumidify the space around them.
4. They are highly insulated, meaning the energy you do use for hot water is not wasted in ‘standby losses’ as the tank sits idle.
5. They are available in large tank sizes, which means that you can easily meet the needs of a 4+ person household with a heat pump water heater.

All of this efficiency translates to savings, with bonus basement dehumidifying! Plus, many states offer cash rebates for installing them.

Due to its much lower electric consumption, a heat pump water heater needs only about 1/3 of the PV modules to generate the electricity for domestic hot water compared to a resistive electric tank.

Heat Pump Water Heater with Solar PV

• Very simple and straightforward installation, can usually be done same day as Solar PV install
• Excellent balance of efficiency and cost
• Long lasting systems come with reliable 25-year PV warranty and a 10-year water heater warranty

Typical Yearly Water Heating Costs for a Family of 4*

Assumptions:

• * Load calculations use 65 gallons a day of hot water for a 4-person household or 16.25 gallons per person. To calculate consumption for a different number of people, or different consumption, just do the math!
• ** Grid electricity priced at 25 cents per kilowatt-hour, solar at 10 cents per kilowatt-hour (roughly the 20-yr cost of solar PV for an average 5kw system), propane at $3.50/gallon.
• *** Oil and propane tanks calculated at ‘average’ efficiencies. There are a few different ways of using oil and propane to heat domestic hot water (direct fired, indirect tank, tankless), this chart uses an average.

There is absolutely no obligation, no pushy salespeople, just high-quality information on whether a heat pump water heater is right for your home and what the next steps would be.
