Warm pool water flows through a slide day in, day out. We calculate how much heat you lose there and how much insulation will save you. And slide insulation is on the Dutch Energy List for the EIA.
A considerable share of a swimming pool’s heat loss occurs in the water slide. With high energy prices, that weighs ever more heavily.
The thermal images below show how heat radiates from an outdoor slide, especially at the joints and flanges.
We fit an insulation package around the slide, between the flange connections of the slide sections. The insulation consists of plastic shell segments and rings, so it is easy to fit and remove again. We match the insulation thickness to your situation for the best return.
A slide is a long, thin tube with a large surface area through which warm water flows continuously. Across that entire surface, the water gives off heat to its surroundings. On top of that, water evaporates in the tube, which also costs heat and makes the air humid.
The air is at least as important. Warm, humid air from the pool hall flows through the tube constantly, drawn along by the water and the riders. An uninsulated tube therefore acts as one large heat exchanger: the air cools against the cold wall and returns cold to the hall. The air handling system then has to reheat that air. The greater the difference between inside and outside, the more energy this costs.
Above all, slides that run (partly) outdoors. In winter the difference with the outside air is large, and wind carries the heat away even faster. Long slides and slides that run many hours a day also lose more. Losses are often greatest at the joints and flanges between the sections, as the thermal images show.
The savings depend on the length and diameter of the slide, the section that runs outdoors, the water temperature, the capacity of the slide pump, the number of hours the slide is open and the insulation thickness. With those figures we calculate the heat loss before and after insulation, so you can estimate the savings and the payback period.
If the slide is still in good condition, insulation is often the quickest way to save energy. If work on the slide is needed anyway, we combine insulation with renovation or extension. For a new slide, we include insulation in the design from the outset.
40%
of the investment deductible from taxable profit
Slide insulation is on the Dutch Energy List (code 210408, insulation system for swimming pool slides). The requirement is a thermal resistance of at least R = 2.50 m²K/W, which our insulation package achieves. This means the insulation pays for itself even faster.
With the EIA you deduct 40% of the investment in energy-saving measures from your taxable profit, on top of normal depreciation. According to the Netherlands Enterprise Agency (RVO), this yields an average tax benefit of around 10%. The scheme is available to businesses in the Netherlands, such as operators of swimming pools, holiday parks and campsites.
Mind the deadline: you must report the investment to RVO within 3 months of placing the order. We supply the insulation data and our savings calculation, so you or your adviser can properly substantiate the application.
The EIA conditions sometimes change from year to year. For the current rules, see rvo.nl/eia or ask your tax adviser.
We calculate the heat loss of your slide and the savings with insulation. That way you know where you stand in advance.

Yes, slide insulation is on the Dutch Energy List (code 210408). Our insulation package achieves the required thermal resistance of at least R = 2.50 m²K/W. You can then deduct 40% of the investment from your taxable profit. Report the investment to RVO within 3 months of placing the order; we supply the data and the calculation.
Yes. The insulation package is fitted around the existing tube, between the flange connections. This is how we insulated the outdoor slide at Center Parcs De Eemhof, for example.
That depends on factors such as the length of the slide, the section that runs outdoors, the water temperature and the opening hours. That is why we make a separate calculation for every slide.
Yes. The shell segments and flanges are easy to remove, so you can check the bolts or carry out repairs to the slide and the lighting.
The gain is greatest for slides that run outdoors. Indoors the difference with the surroundings is smaller, but the tube still gives off heat. We will calculate for you whether insulation pays for itself there.
Yes. We also work on slides by other manufacturers. We match the insulation to the diameter and flange connections of your slide.
