For a 20 kW boiler, a chimney with an internal diameter is suitable 160 mm and height 7 m.
The degree of insulation is determined based on the total heat loss of the building and depends on the material, thickness and number of layers:
- - enclosing structures
- - walls;
- - wall insulation;
- - roofs;
- - roof insulation;
- - roof coverings;
- - floor insulation;
And also on the type and area of glazing and entrance openings.
Examples non-insulated buildings:
The walls are single-layer (without insulation), made of material with a thermal conductivity coefficient above 1.300 - concrete on crushed stone, reinforced concrete, solid concrete...
Roof and floor insulation is single-layer or absent.
Examples of buildings with a low degree of insulation:
The walls are single-layer, made of material with a thermal conductivity coefficient from 0.440 to 1.300 - silicate brick, ceramic brick, slag brick, red clay brick, FBS block, alabaster slab, hollow brick.
The floor and roof are insulated.
Examples of buildings with an average degree of insulation:
Mostly single-layer, made of material with a thermal conductivity coefficient from 0.090 to 0.440 - TEPLOSTEN block, multi-layer construction cardboard, wood, silica brick, ceramic brick, thermal insulating concrete, wooden beams, plasterboard, expanded clay concrete, foam concrete, building gypsum, ceramic brick (hollow), hollow brick.
The floor and roof are insulated.
Examples of buildings with a high degree of insulation:
Mostly two- or multi-layer, walls and insulation are made of material with a thermal conductivity coefficient for walls - up to 1.000, for insulation - from 0.001 to 0.085 - polyurethane foam, fiberglass, polystyrene foam, polystyrene, expanded polystyrene, foam rubber, mineral wool, glass wool, dry sawdust.
The floor and roof are insulated.
