PRODUCT DETAILS

HEAT PUMP SIZING GUIDE: 

• Sizing charts based on 26ºC ambient air temperature 62% relative humidity, no water table, average pool depth 1.35 - 1.5m, minimum running time 10 hours per day. Insulated pool cover applied 20 hours per day, sheltered location.
• Sizing charts are an approximate guide only, results may vary depending on the region, temperature and climate change.

Pool Water Temperature - The normal range would be between 25 - 27ºC for fairweather swimming, for temperatures in excess of this (28 - 30ºC) we recommend increasing to the next unit size.

Swimming Season - The season or time of the year in which the pool will be used. Most domestic pools operate between May to September. Extended season is April to October.

Daily Use - It is paramount all pools are covered with a heat retention cover when not in use. If left uncovered, far more energy would be used than the energy using a heat pump would save you.

Over Spec - Where possible, installing the largest affordable heat pump is recommended, e.g: if the pool requires 100kW of energy to maintain temperature at X (under ideal air temperatures). A 24kW heat pump when delivering max power input (5.88kW) will run for 4-16 hours to heat your pool (100/24kW). This means you would consume approximately 25kW of energy.

A 17kW heat pump with a power input of 3.62kW will run for 5.88 hours to heat the pool (100/17kW). This means you would consume around 21.28kW of energy. While the energy consumption is almost the same, the larger heat pump can heat up the pool nearly 30% faster ((24kW) 5.88 hours - (17kW) 4.16 hours - 29.25%). This means you can maximise your COP by heating during the warmest part of the day, rather than running the heat pump over a longer period when the air temperature is not at optimum levels.
