Finishing around Woodburner

[SJD1]

Hi

I know there have been many posts about this topic as woodburners become more and more popular but I am hoping that someone out there will have the answers I need as this is causing me a massive headache!

I have taken out the old back boiler and opened up the chimney breast to find that I have an arched opening. The house is early 1900's

I want to keep the arch and obtain a smooth finish that can be painted inside the opening and on the chimney breast but it seems that there is no hard and fast way of going about this.

I have researched many methods but still cant decide which would be the best way to go about it. Ultimately I only want to do the job once. So

1. Would a lime render (5:1:1) skimmed with Everbuild 'Purimachos' heat resistant plaster crack from the heat of the stove in the opening?

2. Sharp sand or plastering sand?

3. Would this work as well as some sort of fire board (Enviroboard or promat monolux)?

4. If I render the front of the chimney breast would this also have to be skimmed with a heat resistant plaster or could I just use multifinish?

The stove I intend to install is a Firefox 8 (8.4Kw) by the way.

Thanks

Lime/cement render it. No need for heat resistant or any other type of plaster.

As this comes up so often, I’ve put together this generic post. The DIYnot links referring to render/plaster aspects might be more immediately relevant but you should also be aware of the rest of it. DO NOT use gypsum based plaster or plasterboard (including gypsum based fire boards) in or immediately around the fire opening, it will fail.

You can DIY an open fire or stove install but you need to understand the Building Regs (which changed in October 2010), submit a Building Notice & pay a fee. Your LABC will inspect &, assuming everything is OK, issue a compliance certificate; the BI may want to witness smoke & spillage tests. No compliance certificate may lead to difficulties when you come to sell your property; if you cannot produce a compliance certificate in the event of a problem, your insurance company may invalidate your policy & reject any claim.

Lots of archive threads on this & some things you need to watch out for, read the links but not all may be relevant or apply to you;

Thanks for the replies

Richard C

I have read your posts on this subject previously and found them extremely helpful. In fact it was you who gave me the idea of going with the sand/cement/lime mix.

The install of the stove and the liner will be done by a Hetas installer, that is one thing that I would not tackle myself, especially as we have a baby on the way, i wouldn't take any risks!

The installer is charging £200 to install the liner and £150 to install the stove plus the register plate and liner should come in just under a grand, which i think is fairly reasonable.

Anyway, I have gone with the Sand/cement/lime mix on and in the chimney breast, did it yesterday and its looking pretty good so far and will be skimming the opening with Ever build 'Purimachos' heat resistant plaster. It is quite expensive (about £50 for a 20Kg bag) but hopefully it will be well worth it in the end.

The only thing I am still unsure on is that one Hetas installer said he would insulate all around the liner (with vermiculite), but the one i'm going with says that it doesn't need insulating. Which one is right? and what will happen if it is not insulated?

Thanks for you advice. Will post pics of the chimney later.

I would insulate it.

 

[Richard C]

I would insulate it.

So would I.

It keeps the flue temperature up which will give a better draught & reduce the risk of acidic condensation (which will eat the liner) as the flue gasses cool near the top of the chimney. If it’s a multi-fuel, only burn a low sulphur fuel such as Anthracite or Homefire, don’t burn coal.
