Item number: 8721008756400 View everything from Heatfan > View more: Central heating boilers > This cable allows you to place two Heatfans 60cm apart, instead of 30cm. You do this by connecting two link cables (both 30cm) with this coupling piece.  What use is the HeatFan for me? Firstly, you can enjoy heating the room faster and your boiler will come on at greater intervals and therefore heat the water for heating more efficiently for shorter periods. In addition to comfort, this will mean a small gas reduction. Assuming that the current type and quantity of radiators are suitable for heating the room, you can also choose to reduce the capacity of your radiators, either by replacing them with other types, or even removing a radiator, so that your room can be furnished more to your liking. Savings of 15 to 20% with peaks of up to 30% on the amount of gas for heating the house is a realistic expectation.
