Insulated Pool

Where does the term passive insulated pool come from?

The idea comes from a trend in house building whereby homes are built with extremely sophisticated thermal insulation, allowing a comfortable temperature to be achieved with a minimal heat source. A passive home is made vapour impermeable so that any ventilation can be mechanically operated with heat recuperation.

Pool innovation: the passive pool.

Based on its constructional background and experience, Compass Pools has developed a passive pool. This innovative concept is being marketed with the following structural physical features:

• Extremely insulating – the CFC-free polyurethane insulation material has a thermal conduction coefficient of 0.026 W/mK
• Closed cells – minimum 90 % according to the Remington method
• Compression stress of 250 kPa at 10 % deformation
• Density – roughly 40 kg per m³
• Chemically inert – ensures that the insulating properties do not diminish in time due to chemial or organic degradation processes.
• Waterproof outer wall – a dual-component waterproof layer is applied to the outside of the insulation packaage to prevent any diffusion or osmosis of the outside.
• Closed structure of the inner wall of the pool – as with the vapour-impermeable character of a passive home, this also ensures perfect sealing of the pool. The Compass’s passive pool provides an answer here with the Bi-Luminite® coating technology, combined with a sealed ceramic core.

Footprint, ecology and economy and durable developments.

Compass Pools strives to combine respect for the environment with a healthy economic basis. The passive pool is a perfect example. Together with the solar roll-out cover, the CFC-free insulation layer ensures that heat loss is kept to the minimum.
The energy needed to heat the passive pool is drawn from the outside air with a high-performance heat pump. With an outside temperature of between 15°C and 25°C, for every kWh consumed from the grid, between 5 and 6 kWh are put into the pool water.

A passive pool is achieved once the energy needed for the heat pump to attain a comfortable water temperature for swimming can be generated by using existing or newly-installed photovoltaic electricity panels.
With your passive pool, you help keep your ecological footprint within an economically responsible limit. Such a pool pays for itself far more quickly than a passive home, as the conditions for the functioning of both the air/water heat pump and the photovoltaic panels are perfect during the 6-7 month swimming season of the year.
