A standard 3kW immersion heater will require a fuse rating of 13 A. This is because, it draws a current of 12 A.

For a 3kW heater, you would typically need a 13 amp fuse. This is calculated by dividing the wattage of the heater by the voltage of your power supply (3,000W ÷ 230V ≈ 13A). Always consult the manufacturer's recommendations and a qualified electrician to ensure the proper fuse size for your specific heater.
For a 3kW immersion heater, a protective device such as a circuit breaker or fuse should be rated at least 13 amps to safely handle the load. This is calculated by dividing the power (3000 watts) by the voltage (usually 230V in residential settings). It is important to ensure the protective device is properly sized to prevent overheating and potential hazards.
Power = E2 / RResistance = E2 / power = (240)2 / 3,000 = 19.2 ohmsCurrent = E / R = 240 / 19.2 = 12.5 amperes
Yes it can, you can either us a bestway or intex 3kw heater.
3kw heater heating a 10 foot pool may take 4 to 8 hours for heating it up to 20 to 25 Degrees Celsius. This also depends on the outside temperature.
To size a fuse, you need to consider the maximum current that your circuit will draw. The fuse should have a current rating slightly higher than this maximum expected current to provide protection without nuisance tripping. The voltage rating of the fuse should also match the circuit voltage.
i have a 5ft pool and have a intex 3kw heater how long will it take to heat pool to a good swimm tempature
You should contact a certified, and licensed electrician.
