Heating system for hot tubs, swimming pools and whirlpools

Rexener Bioheater can be installed on a new or existing Spa, pool or hot tub water heating system. Rexener Bioheater can replace your high consumption electric heater or a traditional wood-heated hot tub heater. Water heating can begin before the pool is full of water. This makes the heating faster.

The installation / replacement is easy and you can choose the installation package of your needs.

You can use Rexener Bioheater with biodiesel, diesel or “red diesel”. You can also use the Rexener Bioheater in a suburban area, as the heater will not cause visible smoke or smell that could disturb your neighbours. The high efficiency of Rexener Bioheater heater also means that the use of the heater does not cause much harmful exhaust emissions. In practice, the exhaust only emits carbon dioxide. The heater only needs about 80W of electrical power.

With Rexener Bioheater, you can keep the same water in your hot tub week after week by connecting a sand filter to the heater and using the appropriate pool chemicals. When the hot tub or pool is more convenient to use, the usage is more frequent. You can even get Rexener Bioheater from us with an installation service.

Rexener Bioheater also has the power to heat up a really large 50,000 liter swimming pool – all year round – even in Nordic countries! Rexener Bioheater is truly reliable and we give it a 3 year warranty.

User TESTIMONIALS

I would definitely recommend Rexener Bioheaters to others. It is a top product. I am also very happy with the service I have received in connection with questions about the product. Rexener Bioheater will extend our bathing season, so we will use the bath throughout the year.

Reliable and easy to use

Rexener Bioheater is heating up our swimming pool, whose volume is almost 50 m3. Rexener Bioheater has been easy to use and has significantly increased the use of the swimming pool.

Pool season is all year round

The customer lets the hot tub cool down during the week and he increase the temperature for the weekend when the hot tub is used. This makes its use really cost-effective. The heater quickly heats up the water to the desired temperature, and there is no need to worry about getting firewood.
