FAQ Hot Tubs
- The hot tub must be placed on an even surface that can withstand its full weight. (ca. 2,000 kg)
- The hot tub can be set on a bed of crushed stone, or on a concrete base. It can also be installed or embedded in a terrace.
- In choosing the spot for your hot tub, remember to consider where you’ll drain the water. It is possible to direct the water flow elsewhere with a hose.
- The drainage valve is on the heater side of the tub, and fits hoses with a 25-mm inner diameter.
- Keep the pool covered (sold separately), and maintain good hygiene by washing and drying the pool regularly.
- Use pool chemicals if you want to extend the water replacement interval.
- If you use pool chemicals, keep the water’s pH within the set limits, i.e. 7.0–7.6.
Thanks to its modern design, heat losses are minimised, and the hot tub can heat at a rate of up to 15 degrees per hour* when it is full.
No. Rexener PR200 water heater should not be used with seawater as it can cause problems due to the high salinity and the warranty does not cover any damage that may occur.
It is strictly forbidden to use pool salt, for example to clean the pool. Pool salt can’t be added to water heated by Rexener PR200 water heaters.
- Rexener Aurora and Polar hot tubs can be used in the winter. However, do not allow water to freeze inside the water heater/hot tub/water circulation pump. If you wish, you can keep enough water warm so that it can’t freeze, which means you do not need to drain the device. If the heater is not in use (or the hot tub is otherwise kept warm), the device must be drained before temperatures drop below zero.
- The fuel will keep in its tank, which means you do not need to drain the fuel tank even in freezing temperatures. We recommend replacing the fuel if it has remained unused for a long time.
- Please note! Make sure you use winterised fuel when using the heater in freezing temperatures.
Yes! Rexener PR200 functions perfectly with Neste MY and Aspen fuels, among others.
- Water volume in the hot tub: 1,500 L
- Heating time (+7 -> +38 °C) roughly 2 hours, one hour of which is filling up the pool
- Heating cost ca. €4
When the Rexener PR200 is running, its fuel consumption is 2L/hour. However, its thermostat will turn the heater off when the water reaches the right temperature. When the water temperature falls by 2–4 degrees, the heater will turn itself back on. This helps to minimise its fuel use.
You can lower the temperature to +10 degrees if the hot tub is not in constant active use. This can also help to save energy.
560 gr is the minimum (corresponds to about 20 kg of sand), therefore a whole box is included (700 gr corresponds to about 25 kg of sand). So it is ok to fill the container with 700 gr, but 560 gr (4/5 of the box) is minimal.
- Before passing through the Rexener Bioheater, water passes through a UVC device with a UV light.
- UV light is for clarifying water.
- UV light prevents the formation of algae and reduces potential pathogens in the water.
- UV light is based on ultraviolet radiation, which causes changes in both animal and plant cells.
- UV light clarifies the pool water and minimizes the need for chemical disinfection.
- UV light can also reduce chlorine odor.
- When the power cord for UV light is plugged in, the UV light turns on.
- Always turn off the UV light to avoid overheating when there is no water flowing through the UVC device.
- The UV device stays in good condition when you remember to clean the protective glass of the UV light 2-3 times a year.
– The effective life of the UV lamp is about 4,000 hours. We recommend replacing the lamp once a year.
