Pulsacoil 2000 - Heatexchanger

Post  mathewg on Sun Aug 31, 2014 3:34 am

Hi

I have a pulsacoil 2000. Yesterday I discovered my airing cupboard was full of water. I have dried it out, yet there is a drip about every 5 seconds from the heat exchanger in the unit. I rigged up a bucket to catch the drips and overnight it filled with almost 3 litres of water. As the fill tank on the top is fine I am assuming this is from the freshwater inlet.

If you touch the rear of the heatexchanger your hand comes away wet.

Is this something user repairable or does the unit need replaced?

I am in West Ealing, W13

Check where the leak is from
Pipe work connects to PHE so could be washer.
Or you can buy a new PHE

The leak is coming from the top of the heat exchanger where it joins the pipe labelled hot water to taps. So hopefully the washer is all that needs replaced. Is this an easy enouhg job?

Well you should be able to see whether it is the washer.
If it is.
Then you turn off the water.
Open the taps Hot & Cold.
Place a towel over the pump and catch any water in a container.
Undo the nut, remove the washer and clean any bits off.
Place new washer into nut and tighten up don't overdue it though.
Turn water on, bleed air from taps.
And check for leaks.

Well two hours since i fitted two new washers and not a drip. The washer on the hot crumbled to dust when removed.

Cant believe how simple that was, and £6 for a spanner & two washers was a great price.

Its obviously been leaking for a while.

Thanks a lot for your help.

Hi Matthew,

Sounds like you had a easy fix there - I think I need to do the same thing on my 2000 but looks like my leak is on the other side, I might have to drain the whole system down I think...


Could you advise what washers you used? (Size/type etc) and possibly where you got them?

Many thanks

Peter

Hi Peter,

I went to my local plumbing store (D&D Plumbing & Heating in Acton) with the boiler manuals and asked for the right sized washers. He said to replace both not just the leaking one, and very helpfully drew me a diagram showing what I needed to do.

So not sure what size they were, but they fitted perfectly.
