Thermotec Liquid Swimming Pool Cover

The new Thermotec Liquid Pool Cover is an excellent way to reduce heat loss and hence reduce running costs for your swimming pool.

With the recent increase in energy costs, the Thermotec Liquid Pool Blanket reduces the evaporation of water from the pool and reduces temperature loss by around 3-4 degrees.

Heat is lost from a pool when water evaporates from its surface, so by reducing evaporation, heat loss is also reduced to deliver energy savings

Liquid pool covers are an alternative to traditional plastic pool covers or they can be used in conjunction with a traditional pool cover to reduce heat loss when the cover is removed.

They are useful when traditional pool covers are not used, but the pool owner still wants to reduce heat loss and water evaporation from the pool. For example rented properties, kidney shaped pools or commercial pools.

Thermotec Liquid Pool Cover is a new liquid swimming pool blanket (which replaces the COVERFree and Aquablanket liquid pool cover products)

The polymer based product forms a protective layer of the pool water surface reduce evaporation and to retain pool heat

Unlike other liquid pool cover products that require daily dosing, Thermotec Liquid Pool Cover only requires dosing once per month on normal swimming pools.

It is is biodegradable, non-hazardous and has been independently safety tested.

It can be used on all types of swimming pool including indoor pools, outdoor pools, natural swimming pools and commercial swimming pools.

It can be used on hot tubs and swim spas, but works best when the water is still and flat, so that it can form a protective layer on the water surface.
