Interior and exterior plaster in winter

There are diesel cannons with and without exhaust pipes. If you only have the horizontal blower pipe, it is a model without an exhaust pipe. If a short piece of pipe leads upward from the horizontal blower pipe, that is the exhaust pipe. Some people attach an aluminum flexible ventilation pipe to it and direct it outside. It is important not to block the fresh air openings on the deflector of the exhaust to cool the exhaust gases.

The conventional diesel cannons have about 20-30 kW of power; with that, you have T-shirt weather in the hut in 15 minutes.

Power is needed by the fan on the cannon.

Since a gas cannon produces condensation water, it is disqualified.

How does this differ from the diesel cannon (without an exhaust pipe to the outside)? And what exactly do you mean by condensation water?

Gas should not be used for drying, as the combustion of gas releases water and increases the humidity. Approximately 800g of water vapor is produced per 1kg of propane gas. This achieves exactly the opposite effect. When the gas heater is turned off, condensation can form drop by drop on the cooling ceilings and walls.

A diesel cannon should also not be used for drying.
1. Without an exhaust pipe, the air inside the house becomes poor and soot particles and oil particles can settle on the walls.
2. Due to the rapid and intense heat development, only surface heat is generated.
This can lead to cracking and flaking; the walls are only dry on the surface. There can be entrapment of building moisture beneath the surface that dries too quickly.

Gas should not be used for drying because when gas is burned, water is released and the humidity increases.

This also applies to diesel. Without doing the calculations, I dare to claim that approximately the same amount of water is produced relative to the calorific value.

Although I believe that by heating, significantly more water (additionally) can be absorbed by the air than is produced by combustion. And the moisture (construction moisture and combustion air) has to be removed anyway!

1. Without an exhaust pipe, the air inside the house becomes bad and soot particles and oil droplets can settle on the walls. 2. Due to the rapid and strong heat generation, only surface heat is produced.

Two good and correct points!

Perhaps it's better to use underfloor heating and run a standard drying program?

There are also diesel heaters with under 10 kW and with an exhaust pipe that can be routed outside. Then there are diesel heaters that stand outside – in this case, a flexible duct is used to bring the warm air inside.

Both diesel heaters are very suitable for construction drying. Diesel heaters without an exhaust pipe have the same effect as gas burners, so they are unsuitable. The combustion of 1 kg of diesel produces about 1.4 kg of water!
