how can I understand if my boiler is a combi boiler?

[tekbuz]

hi,

We are moving to a new house and we would like to replace the old system with a combi boiler but it looks like the boiler is quite new and I would like to find out if this is a combi boiler.

The system has a tank and a pool at the loft but the boiler looks like a combi, just can't find anything that supports that other than one plumber who said that we don't need to replace the boiler as it is a combi, and all we need to do is to remove the tank if we don't want them.

The boiler's brand is Worcester 24i condescending boiler.

thanks.

I`m reading this as your plumber has told you the answer already.

that's what confused us, as it was one out of 3.
if this is possible (I didn't even know that was actually possible) then I will assume that the others just didn't notice this detail.

If you have a large tank with water in the loft, and cylinder in a cupboard upstairs then no, its not a combi. The Worcester 24i is a system boiler.

Your heating system layout will look something similar to this:

Thanks Soulman, yes our system layout looks just like that.
So there is no chance that it is a combi and the system left behind as a backup unit?

you currently have a traditional system which most people consider a better system particularly for hot water demand

if the boiler has 5 pipes leaving it it is more than likeley a combi (unles its a 4 pipe viessmann boiler)

thanks Gasmk1, I will check, I think the plumber said that based on the pipes.

never mind the boiler, either way you could still have a cold tank in the loft that could be supplying cold water to a bath/toilet etc.
it's not easy from a question on a screen to see eveything!

worrying to think you have had 3 plumbers look and you are left not knowing what setup you have got!

Does your boiler fire up every time you run a hot tap ?
If it does it's a combi.

Combi in anything other than a 1 bath flat is not a good idea
