Hello,
We have recently moved in to our first house, and are now expecting our first baby.
Working through the list of things to do, one was to replace the heating system, the new arrival has put a slight delay to that.
I am just redecorating the box room to become a nursery and need to remove the radiator - no issue doing this my self, the question is how I go about refilling the system?
The setup is OLD, there is a Concord Companion H 45/55 back boiler, a hot water tank which works on gravity / convection and a central heating pump under the floor boards. There is a drain tap (possibly fill point?) Under the floor boards near the pump. There is no pressure vessel for the heating system, no expansion tank in the loft and no filling loop. There is an immersion heater in the tank, but that has no thermostat so it's very rarely used, in fact there is no bypass valve either on the hot water tank, this gives two issues, if there is no hot water and I switch it on, if the central heating is running it seems to take priority as it's pumped, also if it's a cold day and the heating is on a lot you end up with extra hot water!
I have put a Tado control system which I brought with me that actually controls the setup quite well.
Sorry for the long post but to recap the question is really how I bleed the system after removing the rad?
The boiler does klunk and bang a lot, is this likely air in the system?
Is it worth getting a plumber to refill the entire system with an additive? Will many plumbers know how to fill a system like this?
Thanks in advance.
Jamie
