Easy-to-use air-source heat pump for heating and cooling hot tub water, combined with a filter unit. The water temperature can be adjusted to suit the bathers’ preference. The device allows the same tub to be used both hot and cold. The heat pump is compatible with all Kirami hot tubs.

The heat pump is a sleek unit consisting of a cooling and heating function, a circulation pump, a filter and a control panel. The idea behind the maintenance unit is that it should make the temperature of the hot tub easy and inexpensive to maintain. The maintenance heating consumes a few dozen cents’ worth of electricity per day, depending on the outdoor temperature. The water in the hot tub will remain ready for a swim for up to several weeks, thanks to the integrated automated filter. The specified amount of pool salt is added to the water, and the filter converts it into chlorine. The filter is a replaceable and washable fibre cartridge that is easy to replace. The desired temperature is selected on the control panel, and the thermostat controls the heating or cooling according to the setting. The filter runs whenever the device is on.

The device’s recommended operating temperature is from +8 °C to +40 °C.

The device is ready for use and includes a connection cable and a residual current device.

The total power of the device is about 5 kW.
