I lived in a flat in London, long time ago with storage heaters it was toasty all day. Almost certainly the thermal fuse is gone, you can change it in 5 minutes. It's just a piece of lead-like metal which melts if the thing overheats. Could also be the element - changed one once by unstacking...

In Austria, underfloor heating is very common, it's terrific to walk on warm terracotta tiles when it's -20 degrees outside. But you are correct, underfloor heating is generally at a lower water temp (normally 40 to 60 C). We have radiators in the rooms with wood floors and underfloor in the...

I have a Loblich (Austrian make you probably never heard of - and never want to) 35 kW wall mounted gas Combi boiler/hot water heater. The unit is 4 years old, and it's on its fifth (count 'em, fifth) heat exchanger. There is a fairly loud rattle coming from the heat exchanger. According to...

Thanks for the replies, you are fast! It sounds like I need a softener, that the magnetic or siliphos solutions which help 'a bit' just won't do the job for my situation; A 15 mm pipe in the boiler so scaled that after 6 months there was just a dribble of water getting through. I understand...

We have a 35 kW combo (CH & hot water) unit. It's three year's old and is now on it's fifth (yes fifth) heat exchanger. The last one was so scaled up after six months use they replaced it -- luckily under guarantee as the bill was over 1000 Euros! It's great now, we never had such fast flowing...

The heat exchanger is one unit and the whole thing was replaced, I imagine there are separate coils inside for the hot water and the central heating. There is a thing which looks like a gate valve on the back (center) of the pump, it’s also has a pipe which goes up to the compression tank at...

I should have added that the pump is integrated in the combi unit, so is also 3 years old, there is no sign of the vibration/noise coming from the pump itself. When I bled the system there was no air coming out and there are no signs of leaks, I almost never have to top up the water pressure.

I have a Loblich (Austrian make you probably never heard of) 35 kW wall mounted gas Combi boiler/hot water heater. The unit is three years old, the heat exchanger was replaced 2 months ago as it was leaking. Now it has a new fault and I need some ideas as Loblich say it’s the pipes and my...
