Hot Tub Options
Spa system
Air jets (air massage system)
The air jets generate an invigorating airflow powered by a blower. Three air jets are positioned at each of the four seats, in the shoulder area, providing a pleasant air massage. The jets are available in finely brushed stainless steel. Operation is simple via pneumatic buttons – the first press activates the air massage, the second press deactivates it. The jets are strategically placed in the hot tub to achieve optimal massage results.
Water massage jets (mini jet)
The water massage system uses targeted, invigorating jets of water massage, each individually adjustable via a ball joint. The intensity of the water jet can be regulated by an air regulator on the side panel – turning it counter-clockwise increases the jet (by adding air), while turning it clockwise decreases it. Each of the four seats has two air jets located in the shoulder area. The water massage is also activated and deactivated at the touch of a button and provides a targeted massage effect for different areas of the body.
Milk System
The unique Milk System enriches the bathwater with countless microscopic air bubbles, giving the water a milky-white appearance – hence the name. These tiny bubbles caress the body and supply the skin with a high level of oxygen, which promotes skin cell renewal. The effect is clearly visible after approximately 20-30 seconds of activation. All other whirlpool functions must be switched off while using the Milk System to ensure its effectiveness. Only the LED RGB color light system can be used simultaneously. The Milk System features two pumps and four outlets and is an exclusive wellness option for Koller hot tubs.
Electric heating coupled with a filter system
The 9kW electric heater integrated into the filter system creates an ideal combination of soothing warmth and pure water quality for an unparalleled bathing experience. A special feature is the automatic frost protection function: if the water temperature drops below 15°C (a minimum value that can be set), the heating function is activated. In combination with the filter pump, it maintains the temperature at a minimum of 15°C to prevent frost damage.
During the heating process, the pneumatic whirlpool functions are deactivated to maximize efficiency. Water temperature is controlled via a convenient thermostat with an LED display that shows the heating status and allows you to set a desired temperature.
Installation requires a 400V, 16A, 3-phase power connection. A particularly practical feature: the heating function can be linked to a photovoltaic system via a PV enable relay, so that the heating is automatically activated when there is sufficient surplus electricity.
Power consumption of electrical devices:
- LED lighting: 3 spotlights at 3 watts each = 9W
- Filter system pump: 650W
- Pump for the 12 air jets: 1050W (option)
- Pump for the 8 water massage jets (whirlpool function): 1,250W (option)
Frequently asked questions and answers about the hot tub
Questions about the technology of a hot tub with a wood-burning stove
A solid foundation is essential to ensure your hot tub stands firmly and stably. The installation location, foundation, or base must be chosen so that it is level, load-bearing, and secure against slippage and subsidence.
It is particularly important to keep an eye on the total weight of the hot tub, including water and people, if you plan to place it on your terrace.
It is advisable to burn out the wood stove first, ie you should heat the stove once and let it burn for a while to remove all residues from the manufacturing process. Be careful, experience has shown that this will result in more smoke.
There are no assembly instructions for the hot tubs, as each hot tub is delivered fully assembled. However, you will receive a detailed, easy-to-read user manual with all the important information for using the hot tub.
The smaller 180cm hot tub has a capacity of 1300ml.
liters, while the larger 200 hot tub can hold 1500 liters of water.
The wood stove needs approximately 2-3 hours to warm up (as a guideline), then the water in the hot tub is pleasantly warm ( from 15°C to 37°C ).
With a thermal lid, the water still has a temperature of approximately 30°C the next day.
The exact heating time naturally depends on the size of the hot tub, the outside temperatures and the type of wood used.
Note regarding electrical work: The mains connection must only be carried out by a qualified electrician and must be permanently wired to the house installation.
For a hot tub powered solely by a wood-burning stove, you only need electrical connections for the lighting and the water circulation system. A standard 230V 16A connection is sufficient.
For a hot tub with an additional electric heater, you will need a 400V (high-voltage) electrical connection.
The power outputs of the individual electrical consumers are:
- LED lighting: 3 spotlights at 3W each = 9W
- Filter system pump: 650W
- Pump for the 12 air jets: 1050W
- Pump for the 8 water massage jets: 1250W
Yes, the wood used for the hot tub cladding (spruce or thermally modified wood) is not pre-treated at the factory.
Therefore, we recommend annual wood care for all types of wood, e.g. with Remmers 3in1 glaze .
You don't have to do much to winterize your hot tub.
First, drain the water from the hot tub using the ball valves. The bottom of the tub is designed so that all the water can drain away.
The hot tub and its pipes are designed so that they empty completely when the ball valve(s) are opened. Leave the ball valve(s) open until the next time you fill the tub.
Questions about purchase and delivery
