Rexener Unnukka
We haven’t actually reinvented the bike but made a better version of the old one! The Rexener hot tub is much easier and more comfortable to use than a regular hot tub. Now you can bathe every night, because the Rexener hot-tub is warm 24 hours a day, 7 days a week if you want – and the water is always crystal clear.
The Rexener Unnukka hot tub is made of the best components on the market; we use Europe’s largest hot tub suppliers, Kirami’s, hot tub. This, combined with the high-quality and high-efficiency Rexener Bioheater, guarantees you an unparalleled and effortless bathing pleasure.
The Rexener hot tub heats up with a biodiesel-powered Rexener Bioheater, it gets bath-ready in couple of hours – including an hour of water filling. Compared to many traditional wood-burning stoves, it is fast as a lightning. You decide the temperature that is suitable for bathing and Rexener makes sure that the water temperature stays there – no more ice cold or burning hot tub!
Depending on what you choose, the Rexener water heater uses biodiesel, diesel or “red diesel”. You can also use the Rexener Bioheater in a detached house area, as there will be no visible smoke from the heater to disturb the neighbours. The good efficiency of the Rexener Bioheater means that the heater does not cause harmful exhaust emissions. Practically only carbon dioxide comes out of the exhaust. The heater requires very little electricity.
Rexener Unnukka is designed for 4-6 people at a time. The volume of the hot tub is 1540 liters. Rexener Unnukka is a completely ready-to-use package. By ordering it together with the installation service, you don’t have to worry about anything else than finding a perfect spot for the hot tub.
