During the summer, heat transfer to the surrounding ground cools bdria outside air, while during the winter cold incoming air is warmed by contact with the ground, which has greater thermal stability than air all year round. The authors contend that buildings with window sills and highly insulated windows glazing and frame need no heating appliances under the window or other means to compensate cold air down-draughts.

Condensing boilers are considered more efficient because they recover hvvac of the latent heat held in the water vapour that would otherwise be emitted in the flue gases. Contact details General enquiries T: Please choose one of the following: Such systems usually comprise a length of metal or concrete piping placed underground.

This will depend upon the nature of the combustion system and the temperature within the boiler. Due to the potential for the spillage of electrolyte and the fire and health hazards from gassing electrolyte as well as the need to remove heat generated by the charging processbattery charging rooms require very effective ventilation systems.


This will then cause cold- air currents in the room that will adversely affect comfort. A typical chemical analysis of condensate is as follows:.
