What is HEATSAVR ?

HEATSAVR is an effective ‘liquid pool blanket’ for swimming pools and spas, commercial or residential, that replaces the need for conventional pool covers.  HEATSAVR greatly reduces heat loss and evaporation from the exposed pool surface 24 hours a day.

How does it work?

HEATSAVR is a bio-degradable liquid, which forms a transparent monomolecular layer over the surface of a swimming pool whenever it is calm. This layer significantly reduces evaporation, which not only saves on water heating but with indoor pools can reduce the cost of humidity control and air heating requirements. An automatic dosing system ensures that the correct dose of HEATSAVR is added to the pool at the same time each day.

In non-technical terms HEATSAVR  is a mixture of carefully chosen ingredients which are lighter than water and which automatically float to the surface. The particles of the liquid are attracted to each other so that they always try to form a perfect very thin layer over the whole pool surface. They are individually so small that they are 500 times smaller than the spaces in a super high quality filter.

Unlike a conventional pool cover which has to be removed from the pool for swimming, HEATSAVR  breaks apart whenever the water is sufficiently disturbed but the monolayer reforms whenever the water becomes calm again. Consequently HEATSAVR  adjusts perfectly to changing activity levels in the pool throughout the day. A variable and flexible cover that automatically works whenever and wherever the pool surface is calm.Energy Savings up to 50%

HEATSAVR works like a conventional solar blanket enabling the pool to benefit from direct solar radiation, so an unheated pool will be naturally warmer or a heated pool cost less to run.  Savings relate directly to reduced evaporation and hence pool water heat loss.  Savings up to 40% can be expected although actual savings will depend on location and usage.

  • Save money, water and energy costs and cut CO²emissions.  Proven energy savings up to 50%

Benefits of HEATSAVR

  • Ideal for rental properties


  • Tranparent & more aesthetically acceptable than a conventional cover so no need for a cumbersome pool cover and roller on the patio


  • Far more convenient for guests, simpler and easier to use.  No need to struggle rolling the cover in and out


  • Greater flexibility – works whenever the pool surface is reasonably calm 24 hours per day – works to greater or lesser degree dependant on pool activity


  • More hygienic – conventional covers require stringent and regular cleaning to avoid bacterial growth


  • Automatic dosing ensures correct and reliable application


  • Fully and independently tested for Safety – Non-Toxic, Biodegradable and environmentally friendly


  • Tasteless, odourless, no residue on hair or clothing



HEATSAVR is non-toxic, biodegradable and a completely safe liquid that does not change the appearance of the pool.  It has been fully tested by numerous independent authorities to ensure that it meets the health and safety standards required
