Dead bugs and debris coming out of hot water tank.

The fortic tank has been cleaned. What is the heating header cistern? The plumber used a wet vac

 

[hane2757]

If it feeds the heating system, surely that should have been cleaned out and had a lid fitted when you had a new boiler last year?

Hmm good point. Do British gas usually do that?

Pictures of fortic cylinder
Pictures of cold tank in the loft (disgusting I know)

Can't get pictures inside fortic cylinder ATM But will soon

Both tanks, should have lids on them, in part to keep dirt out, but also to help reduce the moisture evaporating out of them. Before fitting a lid to that loft header tank, it needs a good clean out.

Any heating engineer worth his salt should make sure the system is clean before fitting a new boiler. The header tank is part of that and usually contains plenty of muck. I’d be surprised if the manufacturer would entertain a claim for a fault if it found all that muck in it.

Hmm yeah, thanks. We were pretty naive to it as we had the boiler done pretty much straight away. It's been past the years warranty for the heating system now too so it's only the boiler that is covered.

Do the pictures help anyone understand why I'm getting dead bugs out of the hot tap?

Yeah. No lid on the storage tank. There’s no other way they can get into the hot water system.

Yes there is, it’s the cistern in the loft that doesn’t have a lid, which is completely separate from the dhw system

Could be the overflow, which a bylaw 30 kit is there to prevent, as it has a mesh screen for the overflow for the very reason of which you’re suffering

The cold tank in the loft is filthy and lidless, but as I've said in my post we were told this was nothing to do with the hot water as it doesn't feed the hot water.

So that’s an expansion tank, not a cold water storage tank then?

Yep, feed and expansion cistern.

Yes it's a fortic cylinder. I'll get some pics asap, thank you. The cold tank in the loft is filthy and lidless, but as I've said in my post we were told this was nothing to do with the hot water as it doesn't feed the hot water.

 

[Mottie]

The use of the term 'cold tank' threw me. Never heard an expansion tank called that before.

F&E cistern? Standard plumbing and heating terminology.
