Watts and kWh answer different questions
Watts describe power. Kilowatt-hours describe energy over time. A heater drawing 1000 W continuously for one hour uses 1 kWh. This calculation does not predict how long a thermostat will keep the heater at full power.
Calculate with your own electricity rate
Full-power energy = watts ÷ 1000 × hours per day × days. Cost = energy × your electricity rate. Use the applicable rate from your bill; we do not assume a current Cyprus tariff.
A hypothetical 1000 W heater running at full power for 4 hours per day over 30 days uses 120 kWh. At a hypothetical EUR 0.30/kWh, the energy cost is EUR 36. This is a calculation example, not a bill forecast or published tariff.
Why actual consumption differs
Insulation, outdoor conditions, desired temperature, ventilation and heating hours affect demand. Thermostat cycling changes the time spent drawing full power. Remote control or a smaller heater does not guarantee a particular saving.
Choose for the room
A cost estimate cannot establish suitable heating capacity. Send dimensions, ceiling height, window and insulation information, usage hours and quantity for a model enquiry. Ask about price and availability separately.

Estimate full-power electricity cost
Enter the rate from your electricity bill. This estimates continuous full-power operation. Thermostat cycling changes actual consumption; fixed charges and costs outside the entered rate are excluded.
