Water heaters account for about 18% of the energy used in the home making them the second highest energy user in the average Wisconsin home. This makes choosing an energy efficient water heater for your home one of the most important decisions you will make as a homeowner.

Heat pump hot water heaters pull heat from surrounding air instead of generating heat directly. The heat pulled from surrounding air is transferred, at a high temperature, to water that is stored in a tank. HPWHs are more expensive than conventional water heaters, but they can also cost less than half as much to operate. HPWH systems can be 2 to 3 times more energy efficient than conventional electric resistance water heaters. You can even install an air-source heat pump system that combines your HVAC and water heating. | |
Upgrading to an efficient pump can lead to reduced service calls, increased equipment lifespan, and lower energy bills.
A variable-speed pump moves water the same way as a single-speed pump, but it has multiple speeds instead of just one. That means it can run at slower, more efficient speeds and uses only as much energy as needed to pump water through the system. In comparison, single-speed pumps can only operate at full power and use far more energy to do the same job.
