Is our radiant heat working?
We have radiant heat at home.
We have it serviced (flushed and cleaned, replaced 1 zone valve about 2 months ago). Now that it's cold (temp is 7 deg Celsius outside), our house is only at 18-19 degress Celsius inside the house and the floors are never warm... even if we have set the thermostat to 21 degress (or more).
I have checked the boiler and it seems to be running although the boiler room is about 23 deg Celsius only. I remember for the past years, it has been warm inside the boiler room and the room beside it (the laundry room).
I can't see the flame underneath.
Do you think our radiant heat is working? Or maybe poorly working? Or not working at all? They say that if it's not working at all, it will be very cold inside the house.
Any thoughts? Thanks.
