Wall plaster behind stove cracking

wtd2008

Hi,

I have an Oisín Stanley stove, it is working great but the wall plaster behind keeps on cracking. It is properly insulated and have the flues etc. I got it replastered but the same again.
Has anyone had the same problem? Any solutions? Was thinking of wallpaper but is that going to peel off with the heat?

I don't really want to tile the wall, any idea lads?

Thanks

What's the gap between the stove and wall?

There is a 3 inch clearance from the back of the stove to the wall....not enough?

Definitely not enough clearance. That is obvious. Besides being an annoyance I can imagine this is a fire hazard.

hallo dare

you'll need to put in a heat reflective metal sheet between the wall and stove.

Waterford stanley recommends 14" for the non boiler model.

14" is a big gap. I am installing one myself next week and am trying to find a balance between safety and not taking up the entire room.
Any chance of a few pictures?

Hi.
The 14" clearance is to combustible materials. The wall at a fireplace should not be combustible. I would have thought it should be solid blockwork. You could look at tiling around the stove if it's a big issue.

I was going to suggest a curved metal heat shield but it's so close to the wall I doubt it'll be effective.

In process of putting in a stove also and advised to slab it with fire slabs and paint as he said it will prob crack other wise Working with stove measurements i will only have 80 mm to back wall ( concrete to another fireplace on opposite side) with 175 mm each side.

Get your plaster to use a mix of bonding and skim for behind stove if you want that to paint or as the guys suggest tiling or maybe stick on stone/brick.
most of our stove install are under 100mm to back of builders opening, you will have to paint it quite often.

Thanks for all the responses lads. The installer is back and he suggested as esox28 did to add bonding to the skim. Will see how that goes, if not I will try the metal sheet behind. The tiling could be €€, especially this time of year.

Thanks again!

How long did you leave the cement to dry before lighting the stove? I would think you would need 3 or 4 days at least, and then a very small fire for a rew more days. I have an aisling as well, and originally there as only 3 inches between it and the wall. there was a bit of cracking, but not too noticeable as we used the rear outlet. I moved it out another 5 inches, purely to let more heat into the room, and it seems to be working fine. The pipe you need to use is of a much heavier stainless steel than is sold for oil fired models. I think the 2 foot piece cost 35 euro. Piping for an oil fired stove will apparently burn through in a couple of days, which could lead to you being poisoned or worse.
