Indoor Pools
Indoor Pool Heating and Dehumidification Design Service

Indoor pools have more complex design requirements than outdoor pools due to the need to also control humidity and to heat the pool room air.
We offer a full design service for indoor swimming pools.
Indoor Pool Heating Design Service
As part of our design service for indoor pools, we will discuss with you the planned use of the pool and will design a solution for you to provide:-
- Pool Water Heating
- Air Heating
- Air Dehumification
- Fresh Air Circulation
- "All-In-One" type systems to provide pool water heating, dehumidificaion and air heating. They use ducting to blow the warm dehumidified air over any glass surfaces in the pool room.
- Separate units - ie heat pump for the pool water heating and stand-alone dehumidifier that can also heat the pool room air
"All-in-One" Solutions for Indoor Pools
"All in one" solutions for indoor pools provide pool water heating, dehumidification and air heating from one unit. They achieve high energy efficiency by recovering heat during the dehumidification process and can return this heat to the pool water or to heat the air in the pool room.
The all-in-one solutions use ducting to transfer the warm dehumidified air over any glass surfaces in the pool room.
We sell a range of all in one solutions from Calorex and Heatstar.
These solutions are designed specifically for each pool hall, so please contact us for a proposal to suit your particular requirements.

Separate Units for Indoor Pools
Alternatively, separate units can be supplied for the pool water heating and dehumidification.
We can supply a heat pump for the pool water that can operate all-year round at low temperatures
We sell a range of dehumidifiers both floor or wall-mounted models. These have the option to also heat the pool room air using either a hot water supply from a boiler, or using a built in electric heating element.
Heat Pumps for Indoor Pools
We have specific heat pumps that are suited to indoor pools, for example the Duratech Dura+ and Calorex extended season heat pumps.

Fresh Air Introduction
For an indoor pool, it is also important to introduce fresh air to the pool hall to reduce the chance of mould growth.
We sell a specially designed fresh air unit called the Indux E300.
This is an "intelligent" extract fan that extracts air from the pool hall to the outside, but as it does so, it warms the fresh air coming into the pool hall to provide heat transfer and energy efficiency.

Indoor Pool Heating Design Considerations
In order to design a solution for your indoor pool, we take into account the following:-
- Dimensions of the pool
- Dimensions of the pool room
- Any existing heat sources, eg boilers
- Any existing air heating systems, eg underfloor heating, radiators etc
- Construction of the pool room, ie U-values of the walls and roof
- Insulation in the pool room
- The amount of glass surfaces present
- The expected use of the pool, eg commercial or domestic
- The season that the pool will be used, eg all year round.
- Required air and water temperatures
- If the pool will be covered when not in use
- Ducted all-in-one or separate non-ducted solutions
- Electricity supply, single or 3-phase, any limitations on the supply.
- Dehumidifiers - wall mounted, floor standing, or located in the plant room (through the wall type).
- Construction drawings for the pool room
- Building regulations
- etc..
