Which Boiler?

[kloofnek]

I have a boiler which heats water and central heating.
The water heats up in my immersion tank(this can be run off electric if boiler breaks down)
What type of boiler have I got?

[Zacs-Master]

A combi boiler

Its classed as a conventional boiler.

Combi-Boilers dont store hot water in a tank they heat the water when a tap is opened.

Are you sure ? If you have an immersion hot-water tank surely that wouldn't be combi ? Combis, if I understand correctly, heats water as needed. This sounds more the traditional type boiler to me.

[Zacs-Master]

apologies, emeritus is correct.

[Old_Geezer]

Hmmm... I should be more succinct :-p

[Zacs-Master]

or just quicker ;-)

Don;t think it is a combi boiler,as you have a storage tank.

[kloofnek]

My does not heat the water as it runs through,my electric shower does.
Yes,I have an immerdsion tank all covered in a cosy jacket.Iti s never run on the electric as the boiler heats the water,only once have I had to when the boiler broke down.
It is A Gloworm.

So as Emeritus says..a conventional boiler??? It is quite old,maybe they don`t do them now.

[Zacs-Master]

why do you want to know kloof?

[kloofnek]

The man from British Gas came to do the annual servicing yesterday ,all was ok but as the boiler is old some spare parts are no longer available.I asked him about new ones(boilers) and he said I can still have the same type,don`t want one which heats as it runs.Like having the immersion,a great backup to have, as I know folk who have had new boilers put,those on the wall, which are forever breaking down.I was just wondering what type mine is.

Almost certainly a conventional boiler. This will tell you all you need to know:

Thank you,New Judge,

A combo boiler has no immersion, so that can't be right.

[kloofnek]

If I had one which heats as it runs,can I still have my immersion?

[kloofnek]

Just been reading on Yahoo answers about Combi boilers and most said they hated them!!!

Yes, it's a conventional gravity system, kloof.

Plenty of them still fitted. Combis are great for one or two people. Plenty of family houses have them, but you really can only have one shower or bath (non-electric shower) on at one time. Even when someone opens a tap somewhere, you do tend to notice the pressure drop if you're showering.

There's a system that gives the advantages of both types. It's called an unvented system. You have a conventional boiler with a small top-up tank in the roof, but the immersion cylinder is a "Megaflow". This stores a load of hot water as yours does, but it's at mains pressure.
No big cistern tank needed in the roof, and all your hot outlets are full force mains pressure. Several showers can be operated at the same time, and the bath fills up very quickly.
