Lifespan of a Biofire fireplace?

Unfortunately, sellers only tell positive things. When I decided on a fireplace from biofire, I was told that the air passes through the masonry chamotte bricks from the firebox and heats them up. The stove provides 12 hours of heat with one firing. However, I have rented out the house where this fireplace is installed and never thought that tenants would come up with the idea of heating with this fireplace in winter instead of the underfloor heating. I live in Switzerland, and according to fire protection regulations, not only the tenant but also the owner is obligated to ensure maintenance, etc. Because the tenants fired up the fireplace almost daily during the winter months, I googled the service life of chamotte bricks and found out that these are wear parts. In a firebox, chamotte bricks can be replaced without problems, but the masonry chamotte bricks would require a rebuild of the fireplace, which is associated with many costs. Does anyone know the system and can tell me if the air spaces can be well cleaned by the chimney sweep? I am having an inspection done with a camera; at the moment, the chimney sweep is on vacation. I am glad that I found someone who has an inspection license for fire protection and a camera. Do the masonry chamotte bricks last longer than the specified service life (I have read about 15 years), i.e., do the masonry chamotte bricks last longer than those in the firebox? The previous tenants very rarely fired up during a cold snap, but the current situation is that the actual value is considered; the tenants do not have to pay damages; the house is 20 years old. I built the fireplace for cold snaps during the transitional season and for very special days in winter and not to be used daily instead of the underfloor heating. The fireplace has more installed chamotte bricks than shown in the sketch attached. Because the luxury of providing 12 hours of heat is great, the fireplace is being misused.

the chimney is being used for unintended purposes.

Used for unintended purposes? A chimney is for heating and not decoration like a plant. So the tenants are doing everything right. It's your problem if something breaks (although the fireclay bricks in my chimney have been there since 1980 - until I tore down the chimney three years ago. They were like new.).

Thanks to the person who points to electric fireplaces with the link. In case the tenants ignite so often, even before they go to work early in the morning these tenants light the fireplace, I hope that no one can obligate me to replace a replacement fireplace with the same features for more than 40,000. An electric fireplace can also serve heating purposes. Then there is simply no heating during a power outage. I am curious what results the inspection with the camera will yield. At the moment everyone is on vacation.

A masonry stove is designed to be fired regularly; it just needs to be heated differently than a steel wood stove. If the tenants do it wrong, they will probably have to pay for it in Switzerland as well. A repair should also not cost 40,000.-- CHF. The problem also lies with the manufacturers who claim that you can get a warm apartment for 3 days with one log of wood. In doing so, they all confuse physical units and laws in order to sell their cheap stuff.

Good day Tangolady As the company Biofire, we have read your post. I also remember that we had an extensive phone conversation about this. However, here is the information once again:

[*]A Biofire is designed and built for regular use [*]The fact that your tenants use the Biofire so actively shows that your tenants are very satisfied [*]Rent is a fee for the use of an item. Wear and tear is included in this. [*]Nevertheless, you do not have to worry, because the Biofire storage stones easily last 40 years and more

If you have any further questions, please feel free to ask The management

Unfortunately, sellers only tell positive things. When I decided on a stove from Biofire, I was told that air passes through masonry fireclay bricks from the fire chamber and heats them. The stove gives off heat for 12 hours with one firing. However, I have rented out the house where this stove is installed and never thought that tenants would come up with the idea of heating with this stove in winter instead of the underfloor heating. I live in Switzerland and according to fire protection regulations, not only the tenant but also the owner is obliged to ensure maintenance, etc. Because the tenants fired up the stove almost daily during the winter half-year, I googled the lifespan of fireclay bricks and found out that these are wear parts. Fireclay bricks in a fire chamber can be easily replaced, but the masonry fireclay bricks would require a rebuild of the stove, which involves many costs. Does anyone know the system and can tell me whether the air spaces can be properly cleaned by the chimney sweep? I am having an inspection done with a camera. At the moment, the chimney sweep is on vacation. I am glad I found someone who has a testing license for fire protection and a camera. Do the masonry fireclay bricks last longer than the lifespan stated (I read about 15 years), i.e. do the masonry fireclay bricks last longer than those in the fire chamber? The previous tenants rarely fired up the stove, only in severe cold snaps, but the age value is considered, the tenants do not have to pay damages, the house is 20 years old. I built the stove for cold snaps in the transitional period and for very special days in winter and not to use daily instead of the underfloor heating. It has more built-in fireclay bricks than shown in the sketch in the attachment. Because the luxury of giving off 12 hours of heat is great, the stove is being misused.
