Hi All. Ive got a few issues with my recently installed heating system. The plumber that fitted it did a good enough job of running pipes and installing rads, but i have issues with noise, trapped air and rads heating up slowly, and the boiler was left in defaults for all settings. He also didn't balance any radiators.
The main issue i have is, its split into 2 zones. 1 for the whole house, and one with a single rad for my office (uninsulated space currently). So with both zones open, the furthest rads in the house dont get warm. If i close the single rad zone all is well. If i close the lockshields to balance the single rad zone down, its very noisy when operating just that rad, and doesn't heat well. My theory is as well that the restricted flow on the system using a single rad is causing the air in the system.
Now, i currently have no bypass valve installed either, so pump overrun is an issue when both zones shut. So i need a ABV before the zones. My question, is there a way to automatically balance the single rad, so that when that zone is open, it gets unrestricted flow, but when the main house is open, it balances down? Would an ABV do that job if set correctly or are they just open/closed?
Note ive tried upping my boiler pump (WB 8000) to 350mbar (250 was default). The pump then ran faster but this just increased noise when on the single rad. The boiler read 60% pump modulation when on the single zone and raised to 70% modulation for the whole house being open. (was 70/80% when set to 350mb)
All of this is much more noticeable since i've tried to bring my flow temps right down to 50c
