Swimming comfort guaranteed!


 The heating requirements of a swimming pool vary according to the time of year, the weather, etc. BWT’s teams therefore work to meet 4 key challenges: reduce electricity consumption, reduce noise pollution, limit excess current at start-up and extend product life.

To achieve this, BWT and the CSTB (Centre Scientifique et Technique du Bâtiment) have developed a thermal calculation core for swimming pools.

In order to ensure the optimal size of your heating and dehumidification equipment, this calculation takes into account the performance of the various heating systems, the weather conditions and the characteristics of your pool, both in terms of its layout and how it is used.

BWT Mitsu­bishi Power Inverter (MPI)

Performance and power. Ideal for large pools!

A BWT M.P.I. heat pump compensates for extremely low outside air temperatures by injecting hot gas directly into the compressor. By injecting a liquid/gas mixture into the compressor, a lower discharge temperature can be achieved while maintaining a high COP (coefficient of performance).

The low sound power of this reversible machine, which is compatible with a 60 Hz power supply, will add to your relaxation.

BWT Mitsu­bishi Zubadan (MZI)

Silently heat your indoor pool!

The BWT Mitsubishi Zubadan Inverter (M.Z.I.) heat pump boasts technical features similar to those of a BWT M.P.I. heat pump.

However, an M.Z.I. can maintain up to 80% of its performance, even at very low outside air temperatures.

The BWT M.Z.I. heat pump is therefore a genuine four-season machine, specifically designed for heating indoor swimming pools used all year round, where it is absolutely essential to maintain the nominal heat output.
