Is there something wrong with this underfloor heating setup?
I could not get it to flow through the system, there was water in the system but the gauge did not show any pressure (0 litre/min)
the thermostat, programer, i.e. was all on, the pump is running
apart from the looks, what else is wrong with it? he says it was installed last year but i can not find any information regarding the valves, any body have any idea on the system?
what is the valve on the right of the pump?
