I have a Vallaint eco-Tec plus 832. When the boiler was fitted five years ago, the engineer put a pressure valve on the mains and set it to 3 bar. That would be OK but the pipe for the boiler is taken off from the pipe which goes upstairs and also to the front hose tap. So what I have is low pressure on one section of the system. Downstairs fine but upstairs low in comparison and the hose pressure is diabolical. My question is, can I turn up the mains pressure to the upstairs and just control the boiler pressure at the boiler itself using the loop. Or is the loop just for central heating and seperate friom the hot water system? He told me that the mains pressure was too high but why would that make any difference? Any suggestions will be gratefully received.
I think I have worked this out but correct me if I am wrong.
I am thinking of installing another PRV on the 15mm pipe which goes direct to the boiler from the mains T juction and then opening up the one the engineer put in to max pressure, equaling out the other cold water pressures to upstairs.
