Heating output, electrical input and kWh are different quantities. A realistic estimate uses operating conditions, cover use and the applicable tariff.

Short answer

The kW given as heating output in the technical table is the heat delivered to the pool water.

The electrical input drawn from the supply is a separate value. The energy consumed is expressed in kWh. A daily or monthly cost calculation cannot be made until these three concepts are separated.

COP shows the ratio between heating output and electrical input under the same operating condition. This ratio can change as air temperature, water temperature, humidity and the unit's load change. The highest catalogue COP is not taken as the average for the whole day.

Short answer

At a hypothetical operating point, if the unit delivers 10 kW of heat and the COP is 5, the electrical input is approximately 2 kW.

If it actually runs at this point for four hours, the unit consumes approximately 8 kWh. This example shows the logic of the calculation; it does not mean that a pool will warm up in four hours or use 8 kWh every day.

Quantities used in the calculation

QuantityExampleLimit
Heating output10 kWOnly at the stated operating point
COP5Not a fixed seasonal average.
Electrical input10 ÷ 5 = 2 kWCalculated under the same test condition.
Energy over four hours2 × 4 = 8 kWhAssumes the input stays unchanged for four hours.
CostkWh × the user's applicable tariffOther consumption and tariff structure are assessed separately.

Short answer

Raising the water from its starting temperature to the target at the beginning of the season is one heat load.

Covering the ambient losses to stay at the target temperature is another. The unit's running time does not have to be the same in these two periods.

Alongside the pool's water volume, surface area, wind, cover, target temperature and hours of use all matter. A pool left uncovered at night and one that is covered regularly can consume differently even with the same unit. The benefit of a cover cannot be guaranteed as a single general percentage.

Short answer

The filtration pump, control systems and other auxiliary equipment can contribute to total operating consumption.

The heat pump calculation should not be equated with the electricity bill for the whole installation. Where measurement is possible, the unit and the total system are monitored separately.

The draw of an inverter unit can change over time. Calculating a whole month from a single instantaneous display reading is misleading. For comparison, a record of measured kWh under similar weather and usage conditions is more meaningful.

Short answer

Pool dimensions, province, target temperature, months of use, cover routine, current pump schedule and electricity tariff should be prepared.

The technical data of the unit options are also compared under the same conditions. If the current tariff is not known, no definitive TL amount is given.

With this information, we at Çilek Havuz assess the option that suits the need among pool heating systems. Including the assumptions used in the consumption calculation in the quotation, alongside capacity and installation scope, makes the options easier to compare.
