ICON 23t - Glow-worm?

[Teachmesomethingnew]

Hello there, my boiler is playing silly people.

It is an Icon 23t (brand name for Travis Perkins possibly) - A Glowworm in disguise?

Anyway, the hot water only works properly when the Central Heating is on. Otherwise, you need the hot water taps on full pelt to get any hot water at all.

Any suggestions gladly accepted.

Thank you

Andy

it sounds like the diverter valve

No it's NOT a disguised Glow worm. You should be so lucky!

But it does have a diaphragm-operated diverter and these can be replaced. Don't know if the diaphragm is available separately.

Thank you for your replies, what is it then?
When I talked to a variety of local plumbers they decided it was a Travis Perkins own branded version of a Glowworm. If it isn't, what is it?

Might help me explain the problem better if I know what it actually is!

It's TP's own brand and (used to be?) sold to them by Vaillant Hepworth (the parent company of Glowworm).

Strangely, TP's own website has not got any product data on it.... so I don't know whether the Icon is still current.

Icon is actually made by a company called Hermann, probably in Italy, maybe Germany.

In South London, some spares (including div. valves) can be got from Shoreheat.
