Hello!!! I have a hot water heating circuit with radiators. The problem that occurs to me is that I have to put the boiler to the maximum so that it lasts longer, because if I put it in a lower level of heating, it starts to lose pressure and ends up going out. Call Peisa people came to look at her and told me that I have some loss somewhere and this causes me to lose pressure. Adjust all radiators and none lose. The pipes that go from one radiator to another are thermofusion and I do not see anything on the wall that makes me think of a loss. The walls are not damp. These people have already come several times and do not find the solution and the worst thing is that they charge the visit. I would appreciate if you could give me a hand. Thank you very much

Hello Although the E1 announces the lack of pressure in the circuit, what can be happening is that when put at maximum power the water boils and that steam is vented by the air trap of the boiler and there the pressure is lost; as a first step, two tests must be carried out: one for watertightness and one for water circulation; since if the flow of water does not move with fluidity also happens that. Did Peisa's people check the pump if it works correctly? Regards !

Hi: to discard that it is the boiler you can disconnect the heating and bridge it with a flexible. If this works well you have to focus on finding the lost. If you get a thermographic camera would be ideal.
