Best High Temperature Air Source Heat Pump
What is a high temperature heat pump?
A high temperature heat pump is a renewable energy system that can heat your home to the same temperature level and the same rate as a gas boiler.
It can reach temperatures between 60°C and 80°C, which allows you to heat your home faster than a regular heat pump without having to buy new radiators or insulation.
It accomplishes this feat by using a better refrigerant than most heat pumps—for example, Leomon's machine uses R32, a refrigerant better suited to your home and climate.
Why is it better than a regular heat pump?
Conventional heat pumps take heat from the outside (air, ground or water) and release it inside at temperatures between 35°C and 55°C. This is lower than gas boilers that typically operate at 60°C to 75°C.
So a regular heat pump takes longer to heat your home than a boiler, which means you need a bigger radiator to make sure it doesn't last forever, and insulation to stop the heat from escaping in the process.
A high-temperature heat pump operates at the same heating level as a gas boiler, which means you can replace another without having to buy a new radiator or insulation.
This can save you hundreds or even thousands of pounds in home improvement costs and reduce the time the builder spends in your home. This may appeal to many as 69% rank cost as the most important factor when evaluating which low-carbon product to buy.
You also don't have to change your heating habits because your new system should produce heat at the same rate as your old gas boiler.

When is the right time for me to use a high temperature heat pump?
There is no doubt that the next decade will push to insulate our homes so that we can adapt to low-carbon technologies, especially low-temperature heat pumps.
However, some properties may not achieve a high level of insulation, such as listed and older properties. If it seems unlikely that your heating system will run at 45 degrees, a high temperature heat pump is a great option, and can be installed right now, and you can partially decarbonize your home in no time.
HT efficiency
With the right setup, homeowners can expect a SCOP of around 2-2.5. This means that per unit of electricity, the device will generate 2-2.5 units of free energy from the air.
SCOP is the efficiency of the heat pump in a year. When the heat pump is operating at a higher temperature, the efficiency will decrease significantly in the winter months, and it will be more efficient during the spring and autumn months when it can operate at a lower temperature.
While high temperature heat pumps are capable of heating 65 or 80 degrees, that's not to say they should operate at that temperature. The higher the temperature, the lower the efficiency. Heating systems should be designed as practical as possible to run as low as possible and only rely on maximum temperatures when absolutely necessary.
How to find the installer?
There are many heat pump installers. In all cases, they must be registered with MCS. Installation standards are mixed as we are still getting the technology and demand is rising. We have some of the best heating engineers in our installation network. If you want to explore heat pumps for your home, you can contact us.
