Every indoor swimming pool will require some form of dehumidification and ventilation to control the condensation and evaporation from the warm pool water, without which the fabrication of the building will deteriorate.
Dehumidifying units can be supplied with LPHW heater batteries which will provide pool room air heating, thus eliminating the need for separate fan heaters or radiators. Where there is a plant room adjacent to the pool room, through the wall models (TTW option) are available. This is a useful option for confined spaces or aesthetic demands.
The diagrams below show both TTW and standard options.
A heat recovery ventilation unit is recommended to dispose of stale air without the risk of losing heat.
