I recycled an old cast iron gas stove that was uneconomicall to fix. Paid £40 for it. Ripped out the inside burner and replaced it with a biofuel burner. We have no chimney. It’s a nice feature in the room, puts out enough heat for us. I know they aren’t very cheap to run but we just use it when we don’t want to heat the whole house.
I have a 5kw multifuel stove. A lot of people are chunking some coal on to keep them lit all through the night, but I'll just stick to purposely seasoned hardwood or at least kiln dried.
I've been looking at bio-ethanol stoves with a view to lobbing one in my studio/barn as they don't need a flu, but only kick out 2kw.
I may have to get at least two of them.
I'll be investing a fortune in insulation and possibly installing a fully airtight MVHR (Mechanical Ventillation with Heat Recovery) over the next few years.
The house is about 380 years old and some joker previous owner put cement render over the sandstone rear of the property.
I'll have to get that stripped off and either replaced with lime render or repoint the original lime mortar allowing the walls to breath and dispel any condensation.
Old houses were built with holes all over them which acted as a natural positive input ventilation system.
I'm not sure woodburners are a good idea in sealed airtight new builds.
