ᐅ Tiled Stove / Flue Diameter and Fresh Air Supply Accessories

Hello everyone,

I am planning to separate the living room and dining room in my new house with a masonry stove as a room divider.
The masonry stove will be a tunnel design, heated from the living room side.
Fresh air supply through an opening in the floor slab (no basement).
Heat vents to the entrance hall.
Heat vents to the space above the living room.
Radiant wall toward the entrance hall.

What is the minimum chimney diameter I should choose?
What should be the minimum diameter of the opening in the floor slab for the fresh air supply?

What costs should I expect?

Thank you very much!

Best regards,

Hello, this is no small matter anymore. After discussions with three stove builders, I can give you the following rough guidance.

Heating insert: 3000–5000 (for me, 5000)
Firebrick and construction as a masonry heater: 3000–5000 depending on the size of the wall (remember to have expansion joints installed!)

The chimney diameter depends on the output of the stove. The height of the chimney also plays a role. For 8–9 kW, I need a 200mm (8 inch) chimney.

Your idea for the stove will not be cheap. Always keep in mind that this cannot be calculated precisely, so even if you get wood very cheaply like I do (I pay about 20€/RM), it will never pay off financially and is purely for aesthetics.

Yes, it doesn’t pay off. That’s clear.
What do you mean by impacts?
So, am I roughly correct with 10,000€?
Chimney height 8.33m (27.3 ft)
Your kW figure refers to the whole house, right?

It can be significantly cheaper if you do the work yourself and choose a masonry stove instead of a tiled stove.

First, the room heating load of the installation space must be known. I would avoid the ventilation grille on top (noise transmission).

The interaction with the primary heat source and its heating surfaces is also important.

It can be combined quite well with underfloor heating.

When I search online, the advantages of masonry heaters generally prevail.
