Technical information: - Heat conducting area 2 m² - Power 27kW = raise in temperature is 23 degrees / one cubic meter of water / hour - Chimney connection Ø150mm - The heater features three oblique pipes running through the fire box, improving water heating performance. Use: The heater's fire box must be completely submerged during use, with at least 35 cm of water on top of it. The minimum water level is marked on the heater with a __MIN__ marking. Do not empty the hot tub before the fire in the heater has completely died out and the embers have cooled. In order to reach the specified power output, make sure to maintain a fair-sized fire in the fire box. Empty the heater of ashes after every use. Doing so increases the operating life of the grates. Be sure to read the manual thoroughly before using the heater.

Do a water workout in the hot tub

Bathing in the hot tub is a wonderful way to relax, but with the right instructions, you can also exercise in the tub. Water exercise is great for joints and tissues, and water resistance makes the movements more effective. The warm water also stimulates blood circulation. Physiotherapist Teija Simola has created a workout in a Kirami hot tub that everyone can do in their own tub.
