no hot water

[mjt]

Hi

been to look at a job today where the customer canot get any hot water.

gravity system and central heating working fine

the flow to the coil does not get hot and there is a drain at the bottom of the return after the cylinder which when open dribbles slightly. you can see my hose just on the picture

the system is a bit odd in that there are two lever valves which control whether the hot water or heating or both/either are on.

i have attached a couple of photos to try and explain.

i am leaningn towards a blockage in the pipe to and from or in the coil - its only a 600mm x 350mm cylinder with 15mm pipes.

what do you guys think


the secon picture is of behind the wall shown in the first

Probably choked.

what dya reckon then - drain down and clean it out - if its clogged up in the coil might be a beggar to clear

Tie a bit acorn on to it to outside and fire the mains through it. Might be more than the coil though. A powerflush with some FX2 clears most stuff.

Showing my age! Acorn was a predecessor to hep2o. A bit like calling the radio the wireless.
