Water parks – outdoor

The problem

Outdoor pools need heating for comfort, but as the heat is lost to the atmosphere, new energy must be constantly supplied to keep the pool heated. How can the energy usage and heating costs be minimised?

The solution

Heat pumps are recognised as the most sustainable way to dynamically heat swimming pool water and with a Calorex heat pump you will save both energy and operating costs. Calorex Pro-Pac heat pumps are available for seasonal use during typical outdoor pool summer seasons, for long seasons and even for all year round enjoyment.

Heat pumps

Calorex Pro-Pac commercial swimming pool heat pumps are specifically designed to economically provide swimming pool water heating to high use pools, and larger pools such as those in campsites, leisure parks, water parks and hotels.

Calorex Pro-Pac commercial heat pumps are designed to work during warmer times of year when air temperatures are above 10°C. Pro-Pac heat pumps are suitable for outdoor pool heating or pools with a semi-permanent enclosure to extend the usable period of a normal outdoor pool.

Calorex Pro-Pac Y commercial heat pumps are designed to operate in air temperatures as low as -15°C and are suitable for heating outdoor pools all year round, as well as indoor pools.

Calorex heat pumps can save up to 75% for both operating costs and carbon savings against direct electric heaters, and up to 47% operating cost saving against fossil fuel boilers and up to 60% carbon saving against fossil fuel boilers (based on UK energy costs).


Pro-Pac heat pumps are easy to install on new pools and to retrofit for existing swimming pool systems, with minimal maintenance required. On the basis of pool surface area, water temperature, local climate, season of use and bathing activity, Calorex heat pumps can be designed to accommodate any requirement.

All products are supported by an in-house applications department, distributors and service network.
