What material for the pool heat pump body?

The differences between ABS, ASA or metal?

The swimming pool heat pump is exposed for many years to bad weather, repeated passages and perhaps also unintentional shocks caused by everyday life. So, the “fairing” of this equipment must be resistant and remain aesthetic. ABS has long been the material of choice for heat pumps, but today ASA is replacing it. So how to choose your swimming pool heat pump?

The qualities of metal for the heat pump casing

It is uncommon for the casing of swimming pool heat pumps to be made of metal. Metal is heavier than ABS or ASA, so it is more often used for low power, small heat pumps, for small volume pools such as above ground pools or spas. The metal is robust, but you have to be careful about its quality, it must be galvanized, anti-corrosion treated or epoxy paint must cover it. An anti-UV treatment is essential to guarantee its durability.

The qualities of ABS for the casing of the swimming pool heat pump

Acrylonitrile-Butadiene-Styrene or ABS is a thermoplastic that is both rigid and light, it is used in the manufacture of boxes, in furniture, telephony, toys, automobiles...
It has numerous strengths which have earned it the choice of manufacturing the “envelope” for swimming pool heat pumps. Its appearance can be shiny or satiny but opaque. Its resistance to shocks and scratches is very satisfactory, as is its resistance to temperature variations, moreover it does not deteriorate under the action of humidity and it is recyclable.
However, it has a weak point , poor UV resistance, if not treated.

ASA qualities for pool heat pump bodywork

Acrylonitrile-Systene-Acrylate or ASA has similar characteristics to ABS. However, its resistance levels are superior in all areas, particularly with regard to UV endurance.
Its superiority is particularly demonstrated in the face of weather conditions, which makes it a material perfectly suited to the heat pump sector swimming pool since the latter spends its life in the open air!
It retains, even after long exposure to the open air, bad weather, frost, rain, strong sunlight..., its original appearance and its solidity. More rigid, it has a very good resistance to shocks, to chemical attack and even to the salty water of the sea, however corrosive.
ASA shows very good qualities of adaptation to the rather difficult environment of the pool. This is why it tends to replace ABS.
