Best Heat Pumps for Underfloor Heating

Heating your home is costly and typically makes up about 30% of your utility bills. Regardless, it is a necessity that you can’t do without, especially if you live in a relatively cold environment. The best thing you could do is ensure that you have the correct equipment that’s well maintained and upgraded to meet current standards.

Plus, you’ll have to ensure that your home is properly air sealed, has proper heat insulation, and has well-adjusted thermostat settings. Doing this can help reduce your heating costs by up to 30 percent. However, the biggest move you could make is ensuring that you have the best heat pumps for underfloor heating.

This article provides you with all the information required to help you purchase the best radiant floor heat pump to use for your home. Plus, a list of eight heat pumps that you can install in your home for more efficient underfloor heating. However, before we get into that. What is underfloor heating? What is a heat pump?

Underfloor heating

Underfloor heating is a centralized home heating system used to control indoor climate through electrical or hydronic heating systems placed beneath the floor. Underfloor heating systems are a smarter and cleaner way to heat homes. The system is more efficient and saves energy by directly transferring it to your home through conduction, convection, or radiation.

This heating system gently warms people and objects in a room from the ground up allowing the objects to retain the heat for a longer period compared to other heating systems. As mentioned, underfloor heating can be achieved using electrical or hydronic means. In this article, we’ll place more emphasis on hydronic means.

Hydronic systems for heat pump underfloor heating

Hydronic underfloor heating systems use a mixture of antifreeze (i.e., Propylene glycol) and water to transfer heat throughout your home in a closed loop that flows through the floor, to the heat pump, and back again. These systems are fitted with various types of pipes including steel, copper, polybutylene, polyethylene, etc.

If you plan on installing (or upgrading) your heat pump underfloor heating systems, then it’s only proper that you are aware of its advantages and disadvantages. They include:


Efficiency: Underfloor heating systems are more efficient compared to other types of heating systems. For instance, radiators need to be heated to about 70 to 75˚C for optimum performance while underground heating systems need to be heated to about 29˚C depending on your house’s floor. Plus, radiators often leave cold spots while underfloor heating systems don’t.

Easy to use: Underfloor heating systems are easy to use compared to other heating systems. Plus, they require minimal maintenance once they are up and running (most of them come with lifetime insurance). Most of them have smart thermostats that help you schedule the regions and periods that you would like your underfloor heating up and running.

Work with all types of floors: Underfloor heating systems work with all types of floors. These include wood, stone, or tile. You can rest assured that your underfloor heating system will heat your home regardless of what floor you have.

Safety and comfort: Underfloor heating systems are much safer compared to other types of heating systems like radiators. In addition, you get to enjoy the fresh air that’s more oxygenated (compared to that produced by radiators). Plus, you don’t have to worry about the risk that radiators expose small children to (i.e., heat from the radiator).

Often, these systems can use a single source (sometimes a combination of various sources) of energy systems including boilers, propane, coal, electricity, natural gas, geothermal, or air heat pumps, etc. You need to choose the best heat pump for your home. The heat pump should be less costly, safer for the environment, and more efficient.

Radiant floor heat pump

Heat pumps are an efficient alternative to air conditioners and furnaces regardless of the climate. Similar to your refrigerator, they use electricity to transfer heat from cool spaces to warmer spaces, making cool spaces cooler and warm spaces warmer. For instance, they transfer more heat from the cold outdoors into your home making it warmer (during cold seasons) and vice versa during warmer seasons.

The fact that they transfer (instead of generating heat) makes them more efficient for providing comfortable temperatures in your home. Combining heat pumps with solar systems can make your home more than 300% efficient and provide a greener alternative to your home’s heating challenges.

COP (Coefficient performance)

Coefficient performance is one of the most important factors that you need to consider before buying a heat pump. This refers to the amount of power consumed by the heat pump compared to the amount of cooling power achieved.

For instance, if a heat pump has a COP of 2 (indicated without units), it means that the heat pump produces 2kW of cooling power for every kW of power used. Therefore, using this logic you’ll notice that heat pumps with higher COPs are more efficient than those with a lower COP. For example, the R32 ERP A+++ 20KW EVI DC Inverter Heat Pumps for Hot Water Heating Cooling.

There are several advantages and a few disadvantages of using heat pumps. It’s good to be aware of such critical information about heat pumps before installing them in your home. This information will help you make more informed decisions and determine whether your investment is worth it.


Lower running cost: Heat pumps have cheaper running costs compared to their variants. Installing this system may be a bit costlier; however, there are lots of savings to be made yearly. You should keep this in mind when choosing the best heat pump for your home.

Failure to do so may result in inefficient systems that’ll waste heat and resources making you pay more than you initially did. For instance, you can try the 26KW 36KW R410A Max COP 5.65 Monobloc DC Inverter Air to Water Heat Pump for heat pumps with low running costs.

Minimal maintenance: Heat pumps require less maintenance compared to other home heating alternatives. You could check some systems yearly to ensure that they work properly. This can also be done by professional installers every five years. Ultimately, it’s cheaper compared to combustion heating systems (for instance). You should select heat pumps that have been tried, tested, and proven to work such as those listed below.

Safer for users and the environment: Heat pumps are safer compared to other variants (i.e., those that rely on combustion) since they use electricity when generating heat. In addition, they are more efficient, allowing users to reduce their carbon emissions. For example, the R32 ERP A+++ 20KW EVI DC Inverter Heat Pumps for Hot Water Heating Cooling.

For instance, water source heat pumps have close to 600% efficiency. You don’t want to save energy at the expense of the environment. Thus, you’ll need to install heat pumps that are good for the environment. Now that you know the basics, let’s move to a more important section. Finding the best heat pumps for underfloor heating.

Best heat pump with underfloor heating
Choosing the best heat pumps for underfloor heating in your home is about the best decision you could ever make. However, it’s not that easy. For instance, you’ll need to choose brands that understand your problems and have a ready solution to fix them. The heat pump you select should be able to heat your home effectively and efficiently. It should also have a low running cost.
