The dehumidifiers can either just dehumidify the air, or they can also heat the air. In order to heat the air in the pool room, you can use an existing boiler (eg gas or oil) to provide LPHW (low pressure hot water) to the unit.

As the unit dehumidifies the air, it will then also heat it using the heat supplied by the LPHW supply. 

These units can be located in the pool room or in the plant room, as the Though The Wall (TTW) option comes with the fixings to install accordingly.

Or purchase the Floor stand kit as an alternative.
