Calorex ‘Y’ Range Heat Pumps – Suitable for March – November and All Year Round

The Calorex Pro-Pac ‘Y’ range air to swimming pool water heat pumps are made in the UK (Essex) and purpose designed for swimming pool heating.

The product codes are PPT-ALYN for single phase units and PPT-BLYN for three phase.

They are fitted with a titanium heat exchanger which is compatible with all types of water treatment. All components used in the heat pump construction are designed to give maximum efficiency at swimming pool conditions. Furthermore the choice of materials and construction will give years of trouble free service. They provide a clean and extremely efficient way of heating the pool water. All cabinet volumes are less than 0.6m3 and comply with permitted development requirements.

The built-in energy management controls allow the pool filtration pump to be operated on a time clock. The Pro-Pac will however override the time clock if heating is needed outside the timer settings.

Heat pump sizes assumes the following UK conditions: The entire pool is inground, ground water level is below pool construction, floating heat retention cover is used 20hrs/day and average depth of pool water is 1.3m

Similar in operation to a refrigerator, heat pumps absorb energy in the form of heat and moisture from outside air, upgrading this energy to a usable form of heat through the unique ability of their refrigeration circuit. All Calorex heat pumps contain a fully sealed non-CFC refrigeration circuit which is specifically designed to operate as a swimming pool heat pump. This means that all components used in their construction are designed to give maximum efficiency at typical swimming pool temperatures. Furthermore, the choice of material and construction will give years of trouble free service. All Heat Pumps are subject to a 3 year parts and labour warranty (UK  & Ireland only). The Heat Exchanger is subject to a 5 year parts warranty (labour first 3 years only).
