Pressurised Stove

cluelessx2

Hi,

I am looking for a knowledgeable installer of these. My plumber has concerns due to the infrequency of use in Ireland (we brought our stove home with us from the continent) and has reservations about installing. Would like recommendation of heating engineer/plumber who is familiar with these systems to advise as obviously want to ensure safe install. I've google searched, and trawled this forum, and others, but am not any closer to finding an 'expert'.

Thanks for all/any help,
A

You may find a few who are somewhat familiar, but as for en expert of something that rarely gets installed in the country!

Fair play to your plumber for raising concerns and not just ploughing ahead with it (as some would) as if incorrectly installed you have literally a large bomb in your house.

Your first course of action would be to contact the manufacturer and see if they have an distributors here, if so, they may be able to point you to a trusted installer.

Thanks for response DGOBS - the manufacturer doesn't have any installers in Ireland. (if only!)

The stove is actually installed and somewhat operational. Trying to be cautious we reviewed set-up with the plumber and have included a second relief valve, and also put a 50L tank in the attic in event of power outage or failure of stoves circ pump. This cooling water will only fill in the event of pressure valve going and pressure dropping in system, therefore refilling system with cold water.

Speaking with the manufacturer, they have no concerns with the set-up, and I think that a lot of the concern is in the unknown factor more than anything else, which is why I am hoping to get someone who is familiar with how things are here, and not just ok with it because it works on the continent.

Is the stove done using a semi sealed system

I'm afraid I don't understand semi-sealed?

As in a sealed system but is supplied from a header tank in the attic through a non return valve

Yes - that's what it is now (since we reviewed with plumber), and these in particular are the types of mods I want to get assessed.

Would think that's against regs. Needs to be a open system

There are many on the European market. Would be pretty standard in Germany. Problem here is no Building Control so therefore no checks and no quality control.

Here's one type new to market that does not require mains cooling.

I would not rely on a cooling system dependent upon a non-return valve as they can also stick in the closed position.

Systems that are cooled by replaced water should be mains fed, however, this has its own issue for off-grid homes as usually well fed homes will lose their mains water also when there is a power cut. A small header tank such as your 50 litre tank is insufficient as this will quickly run out of water to cool the back boiler.
Pressurising has many benefits but safety must be foremost. This can only be satisfied by satisfactory control measures.

I wonder how reliable the fail safe heat dump to the room is!

Remember, manufacturers instruction in some circumstance may over-ride regulations, as the regulations do not keep up with advances in design and installation
