And home propane heating is equal to or more expensive than electrics. From what I read earlier, this installation works at the performance limit. The proof is that the cylinder with a propane-butane mixture is freezing. (..)

New laws in chemistry and physics? What is the evidence of low performance?

It is worth using the room regulator and playing with the program. "Dredge" the day to on-off, set economical temperatures, eg 20 * C on - 18 * C off. The boiler has short breaks between one cycle and the next, and this largely adds to the costs ... When heating with propane, it is not worth buying a boiler from the bottom shelf, where there is not much you can do. Setting the power of 8 kW or 12 kW will not change much.

I already rolled a similar topic on another boiler. With this type of LPG fueling, the cylinders (at least 2-preferably 3) should be connected to one battery and work on a common regulator. The reason for switching off the boiler is the lowering of gas efficiency from the cylinder during use due to the drop in supply pressure. The minimum supply pressure switch (in LPG-fired boilers should be included in the boiler equipment) registers too low pressure and turns off the burner. After some time the cylinder heats up, the pressure will increase and the boiler will try to ignite again. Until the end of the world. LPG is one of the most expensive carriers. I suggest using a different type of fuel.

Topic summary

The discussion revolves around a user experiencing high gas consumption with a Junkers Ceraklass dual-function boiler, using a 33 kg propane gas cylinder every 5-7 days to heat a 33 square meter apartment. The user notes that their boiler operates inefficiently, turning on every 10-15 minutes after installing a programmable thermostat, compared to a neighbor's similar boiler that operates every 40 minutes. Responses highlight potential causes for the excessive gas usage, including heat loss due to poor insulation, high ceilings, and inadequate radiator capacity. Suggestions include consulting a service technician for proper boiler adjustment, insulating the basement, and possibly increasing radiator size to improve heating efficiency. The user later discovers a fault in the boiler's control board, which contributed to the inefficiency.
