Hi
I moved into my house a year ago. It's 4 Bed, Victorian Semi over 3 floors.
Since moving in we have had the pump, both thermostats replaced and a new diverter valve because they were scummed up and stuck open.
Basically our problem is that even after balancing the system the ground floor rads are not very hot and the temperature only increases by 1 degree per hour (currently experiencing 13.5 degrees downstairs first thing in the morning). Our boiler is a Potterton 70HE (20kw) and burns for 90-120 seconds and goes off for 60 seconds and then repeats. Is this normal?
We recently called out our service engineers because the boiler keeps needing to be reset. Sometimes it takes up to 20 minutes for it to work! We were told that the heat exchanger is getting clogged with sludge and to run a cleaner through the system for a week and then get a power flush if this didn't work. Sentinel X800 currently circulating the system with all rad valves fully open. The engineer also said our pump wasn't big enough and we would have to pay out for a larger one to be installed as well as putting a tap on the HW tank as that seems to be hogging all the heat in the system.
We have had lots of people out to look at our system in the year that we have been here, one engineer said the boiler isn't big enough, another said the ground floor rads aren't big enough and now we are sludged up.
Can anyone else shed any further light on our issue? I feel like I am going around in circles and really don't want to fork out for an £800 power flush or a £250 up-sized pump if it isn't going to work.
Help!!
Many Thanks
