Apologies if there are multiple answers to this already posted. I did a search in the forum, but there are 1614 pages for plumbing and CH alone! Needless to say, as I'm doing this during work time, I don't have the opportunity to check every thread.
We're renting a house, living in Belgium, and the central heating boiler is an FER Kiwi - I can't find one single piece of information on the internet for a Kiwi boiler, but it definitely says Kiwi on the font. It's a large, oil fired, floor standing boiler (about 5 foot 6 tall) supplying CH and HW. There's a thermostat in the living room, and a separate water temp control on the boiler itself which is set at 70 degrees. The whole thing looks pretty old.
The problem we have is with the radiators. A couple of them hardly give out any heat at all. They are the convector type that look like a small coil of piping, with a large metal cover over the top. My husband has hoovered them to remove excess dust, and this helped a bit. He's also bled them and made sure there are no blockages. However, the radiators are giving out very little heat. The one in our bedroom is only half warm, only the half closest to the inlet pipe warms up slightly (this has also been bled - twice).
When the temperature is +6 degrees outside we can maintain an internal temperate of 22 degrees downstairs. When it goes below zero we struggle to reach 20 degrees. It usually stays at about 19, and about 14 to 15 degrees upstairs. The house was built in the mid 80s and has double glazing and loft insulation. It could probably do with modernising, but as it's rented it's not likely to happen.
Can anyone give me any more ideas as to what might be causing the low heat output on the radiators? All the valves are open, so they should be full blast. The boiler had a full service in October.
Thanks in advance.
