The PVT heat pump

The Triple Solar PVT heat pump is smart, compact and specially designed for the Triple Solar PVT heat pump panels.

The Triple Solar PVT heat pump uses state-of-the-art technology such as the environmentally friendly and natural refrigerant propane and remote monitoring capability. The heat pump uses the electricity generated by the PVT heat pump panels very economically. The energy label is A+++ for both heating and domestic hot water. The heat pump takes up little space, is lightweight and quiet. The accompanying 200 boiler has enough capacity for comfortable showering and is made of maintenance-free materials.

”Our heat pump makes as little noise as a refrigerator.”

Benefits Triple Solar PVT heat pump

Propane as a refrigerant

Propane is environmentally friendly and has the advantage of the wider range of -20 to 50˚C and can make a supply temperature of +70˚C without an electric element. This is ideal for existing homes where radiators are often still used.

Compact and light

The PVT heat pump is extremely compact (48 x 54 x 83 cm) and weighs less than 50 kg. It is the lightest heat pump on the market and can be carried in two 25 kg parts. Regular heat pumps weigh 100-120 kg and should not be moved without a hoist.


An annual service is not required with this heat pump. Maintenance only takes place when necessary based on monitoring. Moreover, the heat pump is mounted indoors, so it cannot be affected by weather conditions.

Comprehensive monitoring

The system can be controlled with a simple thermostat and monitored via the internet. No wifi is required for this. The monitoring allows the user, administrator or service organisation to provide information on operation, performance and preventive service.

Even more benefits


Another special feature of the PVT heat pump is its cooling option. Especially for new buildings, this is important because of the new standard to prevent overheating in July.

Easy mounting

The heat pump has a small installation area and can be mounted either on the wall or floor.

Always works

The PVT heat pump always works, even when it is freezing. As a result, you save more energy than with a traditional heat pump that stops working below an outside temperature of 4 degrees.

Low energy consumption

The heat pump has low energy consumption. The total electricity output of the PVT heat pump panels is usually higher than the heat pump’s consumption.



For the resident

The resident can control the heat pump remotely and gets automatic updates via the SIM card in the interface.


For the operator

The installer or the service organisation can check whether the heat pump is working properly and whether its performance is satisfactory. Also, the installer is notified when preventive maintenance needs to be done.


For Triple Solar

If required, we watch and advise the installer and user. This insight into the installation provides more security and guarantees proper operation over time.


This is how the heat pump works

The operating principle of this heat pump is most easily explained by its components – the evaporator, compressor and condenser – coupled with three stages:

The PVT panels are the energy source of the PVT heat pump. On the back of the panels is a thermal exchanger through which the liquid glycol flows. This liquid heats up through the outside air and the panel. The heated liquid then goes to the heat pump. Inside the heat pump is an evaporator, where the heated liquid evaporates.

The electric compressor in the heat pump then compresses the released vapour. This process increases the pressure inside the heat pump and increases the temperature.

In the condenser, thanks to the expansion valve, the vapour regains space. As a result, the pressure decreases and the vapour turns back into (transport) liquid. This process releases heat. This heat is then conducted to the delivery circuit – the heating system or boiler. The temperature of the released heat is significantly higher than the temperature of the heat originally absorbed and is now usable for heating and hot water. The carrier fluid then flows back to the evaporator, after which the process starts again.

There are two ways to install the heat pump: hybrid and all-electric (gasless). For new-build houses, only an all-electric PVT system can be installed, as no gas can be used. For existing houses, we have developed a hybrid PVT system. This system works together with the boiler and can be installed quickly and easily. This allows more houses to be heated sustainably and quickly saves money and CO2.
