Heat Pump Hot Water Systems

What is a Heat Pump Hot Water System?

As the name implies, a heat pump hot water system is an electrical device that extracts heat from one place and transfers it to another, generally from its surroundings, to heat water rather than using an electric element to heat the water.

It is said to be more energy-efficient than other hot water systems.

What to Consider When Purchasing a Heat Pump Hot Water System

Basically, a heat pump hot water heater is an air conditioner in reverse, compressing gas to produce heat instead of cold. Inside the water heater, a coil of pipe carries hot gas. Heat is then transferred from the copper pipes into the water through it. 

The heat pump hot water system is a great option for homes that generate their own power or run off of batteries. If you plan to buy a heat pump hot water heater, here are a few things to consider:

How many people does my water heater pump need to provide hot water for?
