Hi,
I’ve inherited this ufh system and having trouble after trouble with it. Had someone out 3 times but still problematic.
Flow from gas boiler bottom left, return to boiler top left.
Current issue is return pipes are roasting hot and supply is cold/lukewarm. Flow meters all read 0 and are filling with air bubbles.
Settings are:
Thermometer bottom left - 70
Pump - 3
Mixing valve(red box) - 55
The floor for the 1st zone does heat, 2nd and third zone do not. Actuators open correctly when zones call for heat.
No matter which way turning any flow meters, doesn’t raise or lower the flow rate.
Any ideas? Thanks!
