Am I wasting my money on an annual contract for Solar panels (for hot water) and an air/water heat pump. The company want 232 Euros for what amounts to "a good coat of looking at" which takes less than an hour. Without contract, they wanted over 300...which I refused to pay!
Have been told that solar panels are a closed system and shouldn't even need servicing.
Does anyone else have a similar system or expertise in this area?
