Sustainable heat feasibility research

Senfal optimized heat pumps with energy prizes and green energy: so you are warm and sustainable.

As part of the MIT-feasibility project subsidized by the Province of Noord-Holland with support of the Ministry of Economic Affairs, Senfal developed the optimization of a heat pump. We demonstrated the heat pump could be controlled to save money and contribute to the matching of energy demand with the availability of green energy from the wind and sun. So we connected our software to Felix van Gemen’s personal heat pump.

Your house as a buffer

Heat pumps work differently from your classical central heating system (CV). CVs are often connected to metal radiators, which transfer heat quickly into their surroundings. Heat pumps are connected to concrete floors, which take a longer time to heat up and transfer heat to their environment. Because of this, the use of a heat pump can be controlled, depending on the heat capacity of the house, and the extent to which the house is isolated. This has added benefits: the heat capacity of the concrete floor in the house acts as a buffer, meaning Senfal can turn off the heat pump for a while without affecting the temperature of the room. 

Your floor is worth money

By turning the heat pump off and on according to energy prices, we were able to reduce the energy cost by 10%. While a great result on its own, the real benefit came from reducing the time the heat pump was turned on, and increasing its heat output when it was. This greatly reduced the number of regulating switches of the heat pump, or in other words, the time the pump is turned on. In the end, this is good for your wallet as well as the environment!

The next step

The project has shown great results, and can be improved with more advanced predictions for heat demand in every part of the house. Senfal is looking forward to improve the value of heat pumps in the future.
