Who it suits
- South-facing conservatories
- Orangeries with roof lanterns
- Glass extensions used year-round
- Replacing electric heaters in a glazed room
Why do conservatories need bigger units?
Glass lets in far more solar heat than a solid wall and loses heat quickly at night. A conservatory of the same floor area as a bedroom can need twice the capacity. We size from the glazing area, roof type and orientation rather than floor area alone.
Where can the unit be fixed?
Indoor units need a solid fixing. In conservatories that is usually the house wall, a dwarf wall for a console, or a solid wall section in an orangery. We avoid fixing to glazing bars or polycarbonate.
