Labo-Derva – Provincial research Utrecht (2013)

Practical research into the use of Heatsavr in Batensteinbad Woerden

  • “No increases in the most well-known pool water (volatile) disinfection byproducts have been found. It is unlikely that any adverse effects on the health of the swimmers have occurred and the use of the product Heatsavr can be regarded as safe within the scope of this study.”

  • “After reviewing the analysis results of the microbiological parameters examined, it can be concluded that a dosiage of Heatsavr during the trial period did not cause an increase in microbiological growth.”

  • “It is plausible that the application of the product Heatsavr is responsible for the structural reduction of the humidity (RH) in the swimming hall in the second part of the study.”

  • “The reduction in the RH of the air in the swimming hall has led to a positive reaction among swimming pool employees. They experience the lower RH as pleasant.”

Kiwa Rapport – The Netherlands (2010)

Evaluation of human toxicological effects of using Heatsavr

  • “Based on the worst-case approach, it can be concluded that at the maximum dosage of 0.8ml/l of Heatsavr in the pool water, the expected amount of the product is absorbed well below the lethal dose of the individual components. It is unlikely that adverse effects on the health of the user will occur.”

Research report Aquabasic – The Netherlands (2005)

Research into the Dutch guidelines for swimming pools and the use of Heatsavr

  • “There are no harmful and/or inconvenient effects for persons or materials at the prescribed concentrations based on the consulted health and safety tests.”

Thanks in part to Heatsavr, SPF Amsterdam-Oost pool saved €46,000,- on energy consumption in 2011. With the help of Heatsavr, the night time ventilation dropped from 60% to 30%. You simply know that you use less energy when less ventilation is being used.

Center Parcs has set itself the goal of reducing the energy consumption of the parks by 20%. Under the guise of this objective, Center Parcs started to test Heatsavr’s liquid pool cover at their Kempervennen park in 2014. The result? A return of over 70%!.

The results with the Aquarium tank are confirmed by the results of the use of Heatsavr in the Aqualaren swimming pool itself. Despite the fact that it was relatively cold in the first half of 2013, Aqualaren’s gas consumption was 10% lower than in 2012. This is equivalent to an energy saving of approximately 60 m3 natural gas per square meter of swimming surface per year.

We are very satisfied for a first year using Heatsavr and with the first profit with unfavorable weather, we are therefore full of optimism for the next season!

We have been using Heatsavr on our pool for some time. We knew that something was wrong with the Heatsavr installation when the pool area suddenly became completely wet. The system indeed had stopped working for a while, which was solved directly by the supplier free of charge. The moisture content immediately went down again. It works great.

We are also using Heatsavr again this year in the Boerhaavebad and Houtvaart. The effect is spectacularly visible in the leisure pool. The windows are much less fogged at the whirlpools and there are no or much less steam clouds in the pool.

The results are also good with regard to the Houtvaart (outdoor swimming pool). In the past, we lost the temperatures accumulated during the day at night. During this and last season we had no temperature fluctuations.
