ELLA 150 - great for an apartment up to 70 sqm. It is not intended for houses with the same surface because the thermal conditions are different
ELLA 200 - designed for apartments up to 80 sqm or houses up to 150 cbm (approx. 60 sqm) with good insulation and a simple radiator system (without a distribution network)
ELLA 300 - ideal for houses and spaces smaller than 120 sqm that do not allow three-phase electric power
ELLA 500 - intended for houses up to 500 cbm (approx. 200 sqm)
ELLA 800 - for houses up to 800 cbm (approx. 300 sqm)
The following criteria increase energy requirements and affect the choice of heating boiler:
- Poor insulation, especially on the ceiling;
- Installation: an installation with long paths, passed through walls and/or floor (radiators with a distribution network);
- Spaces with big windows.
In the cases specified above, power consumption increases, often even considerably, regardless of the type of heat source
