All-Electric Water Heating

Switching to an electric heat pump hot water heater can present challenges. Heat pump water heaters can dump cold air into the surrounding conditioned space. This should be avoided (or at least cleverly managed), if possible. One solution is to order a venting kit that brings in make-up air and vents to the outside, thus avoiding some of these issues.

There are newer split hot water heaters such as the Sanden System, which locate the condenser on the exterior of a building, similar to a HVAC heat pump. They are extremely efficient, topping out at a whopping 500% efficiency.
