Is it possible to install a gas boiler less than 5 kW in a room?
What are the minimum gas boilers. The building is about 30 square meters. meters (+/- 5 sq.). And on the Internet I found a minimum of 7 kW. Is there less or not? At least 5 kW?

Hello Anton.
The fact is that among domestic gas boilers there really are very few units with a capacity of less than 7 kW. Most likely, the low popularity of low-power heating appliances is explained by the geographical position of our country and the mentality of compatriots. You need to look in the direction of manufacturers in Europe or neighboring countries - in their product line there are many reliable and inexpensive heating appliances with a capacity of 5 kW, sufficient to heat an area of up to 50 sq. m. Offhand, literally immediately managed to find a good boiler ThermoBar KS-GS-5-S parapet type with excellent automation company EuroSit.
If for one reason or another the desired options do not satisfy you, then feel free to take a more powerful unit with a modulated burner. With a small demand, the modulation mode will reduce the boiler power to the desired value. At the same time, the amplitude of the change in gas supply states directly affects the control range; therefore, devices with deep burner modulation will be the preferred option. These abilities have many branded units. Of course, in comparison with domestic heat generators, they have a higher price, however, this drawback is offset by expanded functionality and extended service life.
