Cheers George.

Fireplace was opened up in stages shown in pictures. The coal grate was set in a lump of concrete and all the brick courses were tied in with screws, it was a real mission to rip out!

I removed most of the valuables from the room and covered the rest in dust sheets. The door was sealed with old towels at the bottom and I removed the waste via the window. After angle grinding I could not see my own hand held out in front of me so quite a fews hours of cleaning before the other half could see the room!

First test firing was a few days ago when it was 30deg! Not pleasant with all the rads cooking in that heat! chocolateteapot

Similar to our woodwarm but I guess yours has a ducted air supply, but how do you empty the ashes? I can't see a door.

With ours I find the primary air lever has two settings,  flat out - close it down a bit, still roaring - close down a bit more, still too fast - close a bit more, ooh - it's now just smouldering!

Hope you have it in a good size room as it will chuck a lot of heat into the room as it heats water.

You will want an Ecofan next.

Regards, Kev

Great choice of stove and great install.

 I presume it's a Wildwood version. My folks have a 12kw Woodwarm and it is the best stove I have ever used or seen in action.

Cheers for the praise, it is a wildwood.

It is in a small room unfortunately Kev but it was the only room that has a chimney. I am a little worried about cooking that room to heat the rest of the house but it does have all the saddle and roof boilers so we will see. Spec says 2.6kw to the room and the room could take 4.5kw so with the door permanently open we should be OK.

I am thinking about if I should insulate and box the pipes in but they do have the high and low states on them and a junction box. Is this a good idea? I assume it would remove more heat from the room but is it safe to box the stats in as they would get super hot?

We have one of these! Really good stove. Well made, efficient, very controllable.

Been using it for 2 winters now. We have the simple back boiler option (not the wrap-around). Think its rated at about 2kW. Heats up the water tank (180l) in about 2-3 hours.

Good choice!

I have a woodwarm fireview with the side and back boilers, don't have any stats or controls on mine just let it pour heat into the heatstore.

Yeah a lagged sensor box could get a bit too hot and it is difficult to make any boxing in/insulation look pretty and the copper pipes look fine.

If I could go back in time I would fit some sort of duct to take the hot air from above the stove and push it to the other end of the house.

nice job!

yeah grinding/cutting brickwork indoors is not fun! I did of job of it before i bought a full positive pressure respirator for smithing, it was not nice with disposable face masks, rubbish googles, ear defenders and a carrier bag over my hair, ha ha!

How do you transfer this much heat into your heatstore Kev ?
How big is the heatstore ?
and do you ever get kettling or boiling conditions ?

Just convects up to the heatstore upstairs no pumps or valves in the (28mm) pipes, the Heatstore is 180ltr if I remember right not really big enough but the biggest we could fit in the airing cupboard - not at home now so can't check.
The only time I get a bubbling noise is if I open the bottom door to get it going and forget to close it.

Update!

Cant believe its been 7 years!

First off running a 12w boiler is not easy. I am a landscaper and 25% of my business is tree surgery and it is still tricky to find fuel.

Running 9 rads and a hot water tank takes a quite a few logs! It keeps me fit and virtually carbon neutral so I'm happy but it is hard work.

I have fitted an electric back up boiler for emergencies and when I am away and the other half/kids need a top up.

When the boiler dies I will probably exchange the stove for a dry one and use the wet system as an electric back up.

Shout me if you have any questions on solid fuel as I have a good 15 years experience in 3 house now so would be happy to help if I can  Smiley
