knocking out fire place for log burner

After a bit of pro advice if we have any stove fitters among us!

I am installing a log burner, so far removed the gas fire, which apparently was installed infront of an old open fire and back boiler. I have removed the old yellow bricks back to the original opening side ways, but I need to know if I can go any higher? The gather seems to come in very low, and a lot lower one side than the other. It also looks like there is no lintel, so this is going to have to be fitted at some point. I think I can possibly go further back as there doesn't seem to be any space for a back boiler, although the pipe work for it is chased out through the brick work on the left

Not a builder before if go any further.

In hindsight when we had ours put in I would have gone  as high as possible, raising the lintel if possible.  The flue increases the heat radiation into the house. So the longer the flue the more heat is in the room and  less up the chimney.

I want to go higher, but I'm not sure how much of the brickwork on the right I can remove before the house falls down! It comes in quite sharply to form the right size hole for the clay liner, if I could square it up to the same as the left side it would be fine

You need to see if the bricks are key'd in to the walls further up if they are you can go up as high as you like providing you lintel the face bricks.

Always need to lintel even if its just a steel plate. The last thing you want is your newly plasterd wall cracking when a brick drops from the heat of your burner

I would put a lintel in anyway but without actually being there it is difficult to advise just on a photo.  It looks like you could square the right side up and then put in a lintel.

How big is your room ??  I have the small Clearview wood burner in my lounge which is 15ft square and when we get that up and running we have to open the doors.  On a really cold day I will light that stove and the large version in the kitchen and they heat the whole house ...16th Century farmhouse three storeys.  I don't think you need worry about exposing the flue pipe for extra heat.   Put in a steel chimney plate with a trap for access to clean the chimney occasionally  or you will need to put an access in the wall above the lintel.

Would really recomend putting a stainless liner down your flue for performance and safty. Open fires throw loads of heat up the chimey pushing alot of soot out to top where stoves are alot more efficient and the flue will be alot cooler so the soot will be deposited in the morter lines and increase the risk of a chimney fire.

I have 9m of stainless flue liner in the garage waiting to go in, I just need to go higher to fit everything in, ideally without the clay liner and the chimney stack ending up in the lounge!

If some of your bricks arent key'd in above you can do something simular to this drilling some 1/2 inch bar into the back and supporting the front onto the lintel

Ok, so you have extended that to the left? And what was supported by the brick is now held up by the bar, because the other issue I have just spotted is that the existing flue is not central in the opening, making it nearly impossible to get a piece of vitreous to line up ?

These are different jobs just some recent ones to give you an idea. you will have to go up another meter or so removing the clay lined pots as you go (i think you said it was clay lined!) Then when you drop the liner down you can bend it to the center or if its a bad angle still bend it over and stick a vitrous 45 on top of the straight lentgh above the lintle/ register plate so you cant see it. Make sure the flue never goes past the 45 degree though ??

The pic with the bars under is the same as the one above the opening was taken out an extra brick lentgh past the original opening ither side so that was to support the already solid internal featherings of the stack. Never give anything the oportunity to fall. It will never fall as bad as you think it might though as it will only drop from the widest point to a triangle above

use a balanced flue...and dont set the log burner back into the fireplace hole............if i were to do mine again i would have it raised a foot off the floor on a hollow plinth where i could store kindling...and i wouldnt have to keep bending down to load it....and i rekon the convection would be a lot better.........

just a thought anyway...

If you have the option I would advise external flue for the air feed rather than allowing air from the room to enter the burner. It significantly reduces cold air coming into the house, allows for a smaller fire and less fuel for the same level of heat. 

I also have a solar flue in the room so opening the flue allows the hot air from the fire to travel through the room.

Do you rate those fans ?   I have two Clearviews in this old farmhouse and it is mainly open throughout including the original  1600s (Jacobean) staircase and thought to buy at least one of those.

The fans make a hell of a difference. Without it the heat stays around/above the fire, but as soon as this gets spinning, you can really feel the heat being pushed around the room. (We’ve got a double fan on a small stove because I managed to order the wrong one off eBay...)

Hopefully you will see from my pic earlier one of the fans. Yes they do make a hell of a difference

What's a solar flue in this context? I did a bit of googling but came up with things to extract heat from sunlight, not to spread heat about within a room...

In the lounge the ceiling is removed up to the roof and a electric glass roof installed. In the summer hot air rises in the space and cold air is allowed into the house from the north wall. In the winter it warms the room or if the burner is on and i open the roof heat is drawn from the fire across the lounge towards the void and out through the roof. Mine is a bungalow but if the house were two storey its the similar to opening windows upstairs and allowing the heat from the fire to be drawn to the second floor. It works better with an external air supply for the fire otherwise cold air (following the easiest route) can be drawn down the stairs to service the fire.
