Building a foundation for a wood stove. Am I thinking wrong? How should I think?
Hello there!
Planning to build a foundation for a large wood-burning stove from the 1930s, weight about 120kg. The house is from the mid-1800s. There used to be a long stove next to an AEG stove at the site.
I plan to cast a slab on the ground (on gravel) about 1x1m. Build up with reused hollow concrete blocks (holes facing down). Cover the concrete blocks with reused fire-resistant red brick. The idea is for the wood stove to be slid into a compartment without a roof. The upper part around the stove will also be red brick. There might be a compartment for wood storage in the foundation.
Questions:
1 How thick should the slab be, is 10cm enough?
2 Do I need to reinforce the slab?
3 Is it okay to use hollow concrete blocks?
4 Reinforce the concrete blocks?
5 Is it okay to cover the concrete blocks with fire-resistant red brick?
6 How large a gap between the wood stove and the concrete blocks in the compartment, is 2cm around enough (any purpose other than being able to slide the piece into the compartment)?
I haven't done masonry before but have done tiling quite a bit.

Are you going to have a masonry chimney?
If you're just placing a wood stove without a chimney breast, you hardly need to cast a square meter sized slab. Instead, you can cast or masonry a pillar or two under the stove if you don't want it directly on the joists. You also don't need fireproof bricks, although it certainly doesn't hurt to reuse the material you have.

Hello, thank you for your response. Have new stainless steel hoses and (newly polished chimney).
No floor joists under the spot for the foundation, only the ground. There is a 1x1m hole in the corner against the chimney which I plan to take the opportunity to fill in...

How good. Can they withstand the heat from the wood stove?
