Back boiler stove and gas

Thanos

hi Folks,

We have bought a house and are thinking of doing some work on it. One of the things we would like is a stove. I would also like to make this a back boiler stove so it could heat the radiators and water if possible.

I have talked to one or two people about this and I have gotten "not sure you can do this" to "this cannot be done as you have gas heating already"

I believe it can be done and was wondering if any one out there has got this done before (or does it). If you could PM me the details of the plumber you got that would be great and let me know if they were good etc.

I have heard that I may need to separate pumps and pipes but again not sure how true this is. Also can it be done if it is a closed system? Does it need to be an open system?

Thanks in advance.........

Its must be an open system.
You will need a new duel coil hit water cylinder.
Pipework will need to be run from where the stove will be up to the hot press.

There is a possibility that you might not be able to do it as a lot of gas boilers won't work with an open system.

You could use a system link with their plate heat exchangers but the process would be very costly....link here...http://www.systemlink.ie/products/plate-heat-exchangers

Are these any good in a domestic situation? I've fitted dozens of them but only on bigger systems, usually with steam or mthw, never saw one fitted in a house.

I have also used them by the dozen in domestic houses and some commercial.
Some of the domestic houses were quite big.
Multi boilers, multi zones, solo heaters on one zone rads in another so on.......
Them solo's needed a large volume of heated water and do not like to be mixed with rads so system zones the perfect solution.

Great fix for a house where the pipe work was under sized pump for each zone.
System lex made it easy for electricians.

How much are them system link equipment ?

I have an oil condensing boiler and a stove with a back boiler on the same system. Its an open system.
No need for a dual coil cylinder. A lot of plumbers wont do it but it can be done easily enough.

I know it's an old thread, but, for anyone with the same question(had this answered recently ourselves):

It can be done, but, it will depend on your gas boiler. If it has a "pressure gauge" then you need a new boiler, that doesn't have this pressure system, to allow it to be used with the boiler stove. If not, then it should be possible and there are plumbers out there who seem comfortable doing so.

If anyone can add to this though, if you have 10 radiators and only need the stove to heat half and the gas/oil boiler to heat half, is it much hassle to separate the two? ie. have the gas/oil heat the bedrooms and the stove to heat the kitchen/living rooms and the water.

Presume it depends on the pipe setup, but, being near-oblivious to the workings of plumbling.....

It's always been possible to add a back boiler to a gas boiler with a plate heat exchanger or system link but it's never been acceptable to have a back boiler on the same circuit as a gas boiler as the back boiler can have a negative impact on the gas boiler which will then require a notice of hazard as the boiler is not fitted to manufactures instructions .


The only time i'v seen split system like you mentioned was when the two systems were completey separate, which would be hard to do on a retro fit.

It works, but when the fire is not lit, the back boiler saps quite a lot of heat from the system when the oil is on.

Absolute nonsense. Just cause it works doesn't mean it's done right.

hi just reading your posts to link a duel system ,the best way is a thermal store ,it is costly but it works brilliant i have oil and solid fuel ,i made my own thermal store ,a lot of work but it is worth it ,just go to you tube and type in thermal store and you will see how it works ,i put the external heat exchanger on mine for instant hot water at taps and shower,look it up hope this helps
