Heat Exchanger Descaling Kit

[WHPES]

Here's one I made myself last week for descaling heat exchangers. Works a treat

You need

1 old F&E cistern

Copper pipe and fittings

2 solder 1/2" tap connectors

1/2" gate valve.

Basically what I did was fit up an old F&E tank with a 15mm copper outlet with an elbow going down, about 1 ft of pipe to an elbow and 4" of horizontal pipe with a tap connector at the end You fasten the heat exchanger onto this at the bottom. Above this I made a piece of copper pipe fitted with a tap connector and gate valve, long enough to dangle into a bucket

The cistern sits on my workbench and the bucket below. With the valve closed, I load up the F&E cistern with warm water and descaler and set the gate valve so it slowly drips into the bucket. I left it for a couple of hours and by the time I came back all the decaler had run through and the exchanger had been cleaned.

Will try to post a photo later

sorry but where was the heat exchange? in the bucket or just above bucket? why not just stick in bucket of descaler for a couple hours?

The heat exchanger was suspended above the bucket. Trouble with just sticking in a bucket if its badly scaled it doens't get right through it fully and it takes much longer to do.

cool, thats what I suspected, good little set up, especially if you have a lot of these.
