Hello Guys,
I just recently installed a ecotec plus 825 which is working fine. The customer is complaining about their only heat source which is ufh rehau.
The problem they experiencing is no heating. I have been out and investigated the works again. I have made sure the boiler is functioning fine as well as hot water so i can definitely say the boiler side of it is good.
The previous boiler was a very old baxi boiler which was connected onto the ufh in 15mm to the manifold. Customer has complained before that the ufh never worked properly and that someone came out and hard wired the ufh.
So, my problem is that whenever my boiler is running is pushes against the other manifold pump and in return it pushes back into the boiler flow. The boiler goes into the Burner anti-cycling time. It just indicates it does not get the heat away towards the ufh. the previous engineer took all the actuators off and the thermostat at the return side. i can see by pressing the pins that each zone is functioning and open. but somehow it seems like it never worked before. I obviously connected the flow to the flow side as it was before but i cannot seem to understand why it doesnt work.
Is it not better to take the pump of the manifold and let it run like a radiator?
I do not seem to understand the way they installed it. It could have never worked as the connections and piping is exactly the same as it was before.
It doesnt seem like to circulate. I always have to turn the pump at the manifold off otherwise it pushes back into the flow and the pipes gets really cold.
