The Elga is a smart modulating hybrid heat pump that can work side by side every gas boiler. The Elga provides for the rise of energy-efficient housing due to its attractive payback time.

The indoor unit will be placed next to the gas boiler, while the outdoor unit will be placed on the roof, in the garden or attached to the facade. It takes one day to install the Elga and it is suitable for almost every (post-insulated) housing.

The highest efficiency will be achieved in all circumstances by combining the Elga with a gas boiler. The gas boiler will turn on only when needed for heating or when preparing hot tap water.

Your indoor comfort will be the same as you are used to with a gas boiler. The efficiency of the Elga heat pump will decline only with low outdoor temperatures, this is when the Elga will turn off and the gas boiler takes over. There are several possibilities for the Elga settings, this depends on the characteristics of your housing and the gas and electricity price.

Using the Elga will save 50-90 % on gas consumption. No gas is saved when preparing tap water. The energy costs savings will be 20-35 %, when taking the extra electricity costs into account. The Elga does not prepare tap water, because usually the efficiency of an electrical heat pump to make tap water is quite low.


The Elga heat pump can also be combined with district heating. You can save on the variable costs of district heating. Your annual fixed charges will be the same, because the district heating connection will stay in place.

In addition to heating, the Elga can cool. The Elga is capable to lower the temperature of the housing with a few degrees during summer if your delivery system is suitable. It is not possible to cool using radiators.

The Elga has the energy label A++, this makes it possible to increase the energy label of your housing with 2 steps.

Monitoring the Elga is possible by acquiring the smart Anna thermostat. This thermostat is especially customized for you to be able to see when the Elga is operational or when the gas boiler is active.

The annual savings on your energy bill by using an Elga will usually come down to 200-500 euros.
