Frequently asked questions
Why is the pool a wellness hotel’s largest energy consumer?
Basin water is circulated, filtered and heated to 28–32 °C around the clock, and the pool hall is permanently dehumidified and heated. Evaporation is the largest heat loss — together often the single biggest item.
What do a pool cover and night setback achieve?
The cover slows down Evaporation outside opening hours; together with a night setback of temperature and circulation, heat and pumping costs fall markedly — unnoticed during the day.
How often must a sand filter be backwashed?
Nach dem filter pressure, not by the clock: once differential pressure exceeds the setpoint, the filter is backwashed. Pressure-led backwashing saves water, chemicals and heated basin water.
What is heat recovery in an indoor pool?
A heat exchanger transfers the energy of the warm, humid exhaust air to the supply air (and partly to the basin water) — around 63 % recovery rate at the reference site.
How does Stromfee connect existing pool equipment?
Read-only: Bayrol/Hayward over Modbus (basin temperature, pH, ORP), circulation pump Grundfos MAGNA3 (speed, power, energy), sauna over KNX/Modbus. No interference with the control loops.
What does the AI see that the pool controller does not?
Steigende Evaporation, needless circulation outside opening hours and a clogging filter (differential pressure) — and it aligns basin heating, dehumidification and PV with one another.
