What is a Heat Pump Water Heater?

A heat pump water heater is a modern water heater which does not consume much fuel. The heater uses natural air and heats water with it. There is a simple working phenomenon in heat pump water heaters, which allows for a compact frame.

They run on electricity mostly, which ensures a clean layout, even when installed indoors. This is why they are so successful in the market nowadays. 

How Does a Heat Pump Water Heater Work?

A heat pump water heater works on the principle of “air source heating.” It takes in the air from the outside and uses its temperature to heat up the water in the tank. The pump absorbs heat from the air, but it does not rob the air of any moisture.

It uses electricity to run its filter and provides purified water. It also helps in saving about three times the amount of electricity over usual water heaters. So, getting a new heat pump water heater will improve the water heating experience for you.

What to Look For When Buying a Heat Pump Water Heater

In order to enjoy a continuous supply of hot water, you need to have the right heat pump water heater. Here is what you need to look for while making a purchase.

Water Storage Capacity

Water storage capacity is an important factor to consider, as it affects the supply and flow of water. Most of these water heaters have a storage capacity of 40 to 80 gallons. On average, a household needs about a 50-gallon capacity, so choose according to your needs. 

Energy Efficiency

Energy efficiency is another significant factor that affects the quality of a heat pump water heater. The efficiency of both SEER and HSFP rankings are important. So, go for a heat pump water heater with at least 14 SEER and 9 HSFP for better functioning. 

Heat Boost

Heat boost plays its part in minimizing the time needed for heating water. Some of the water heaters have a heat boost of about 20 minutes. This helps in providing hot water almost immediately after turning on the heater. 

Sacrificial Anode Rod

You must also consider a sacrificial anode rod while buying a heat pump water heater. This helps in protecting the heater from any rusting, as it rusts itself.

Heat pump water heaters are quite efficient, so people prefer them over others. If you are one of those and want to buy a new heat pump water heater, then you are in the right place. Here is a complete description of our favorite models to help you out.
