The answer depends on where in the world you are buying it and in what form.
This depends on the cost per kilowatt hour in your area.
800 to 1500 BTU's
OK
Yes, usually. 100 watts equates to about 341.21 BTU per hour.
1 kW is equal to about 3,412.14 BTU/hour.
The cost to heat a pool can vary depending on factors like energy costs and usage patterns. However, you can estimate the cost by calculating the BTU input per hour of the heater (399,000 BTU) and factoring in the energy cost per BTU in Pennsylvania. You can then multiply the cost per BTU by the number of hours required to heat the pool to 80 degrees Fahrenheit to estimate the total cost.
To convert BTU per hour to frigorias per hour, you can use the conversion factor 0.251995760032 BTU per hour is equal to 1 frigoria per hour. Therefore, 3988777 BTU per hour is approximately equal to 15886.05 frigorias per hour.
7.5 kW equates to 25,591 BTU/hour.
1 cal/day*0.003968321 Btu/cal *1day/24hr = 0.003968321/24 = 0.000165347 Btu/hr
To convert kilowatts (kW) to British Thermal Units (BTU), you can use the conversion factor 1 kW = 3412 BTU/hr. Therefore, a 5 kW heater would produce 5 kW * 3412 BTU/hr = 17060 BTU per hour.
12,000 BTU/hr
