Heat Pump vs. Boiler Comparison in 2021

Heat Pump Overview

People often prefer to go for a heat pump due to the advantages it provided. These electrical devices are highly efficient when it comes to energy consumption, preventing electricity loss that would lead to more money spent.

Heat pumps transfer heat from one area to another. This process is possible due to air compression, which comes very handy in moderate climates.

Besides saving you some money by using energy efficiently, heat pumps also require fewer expenses on maintenance. Another reason you may want to consider these devices is that they’re eco-friendly, meaning less chemical pollution.

Differences between Heat Pump and Boilers

Alright, so what are the differences between these two types of units? Let’s find out.

Purpose

As the name suggests, boilers do one thing, which is to boil water. Normally, they work on either natural gas or propane, which powers up the boilers to heat water until it’s hot. Then, the water goes through the pipes to reach different areas in the household.

On the other hand, we have the heat pumps, which are independent units that don’t rely on a radiator to warm or cool the room. But how does it do that? The heat pump absorbs and transfers thermal energy to the coolant to create a high temperature.

Temperature

Since many boilers operate with a radiator, each area of the household can have its unique temperature. That doesn’t happen with the heat pumps, though, as these units cover larger areas of the house, providing the same temperature throughout the household.

Efficiency

The efficiency of both boilers and heat pumps varies depending on several conditions like climate, and the model of the unit itself. Commonly, heaters have an AFUE rating to let you know the amount of fuel converted to heat.

A high AFUE rating means the unit is far more efficient. Whether you’re looking for a boiler or a heat pump, the energy-efficiency rate is important.

Conclusion

As you can see, the heat pump vs. boiler is a debate that requires plenty of thought and consideration. Make sure to give each appliance a try to see which one is the most suitable for you.
