Our take on the 3KW Pool Heater Electric Swimming Pool And SPA Bath Heating Tub Water Heater Thermostat Swimming Pool Accessories

This is a 3 kW single-phase electric inline water heater for small pools, hot tubs, spas and baths. It runs on 220–240 V mains power at about 3 A and connects to plumbing through roughly 50 mm intake and outlet ports. Its stated heating range is about 1 to 2 cubic meters of water, so it suits a small above-ground pool, a plunge pool or a compact spa, not a full-size pool. Against gas and heat-pump heaters it is simpler and cheaper to install but far slower to heat a large volume, and it has no built-in pump or filtration.

Questions and answers

How much water can it heat?
The stated heating range is about 1 to 2 cubic meters. That covers a small above-ground pool, a hot tub or a large bath, not a full-size swimming pool.
Does it include a pump?
No. It is an inline heater only, so water has to be circulated through it by a separate pool pump or spa pump.
What power supply does it need?
It is a single-phase 3 kW unit rated at about 3 A and 50/60 Hz, so it needs a proper mains circuit. Have a qualified electrician check the supply and wiring before installing.
What size plumbing does it fit?
The intake and outlet are about 50 mm, which matches common pool and spa pipework. Check your existing fittings before buying.
Can it be used for a bathtub or pond?
Yes, the listing names baths and ponds among its uses, as long as the water volume stays within its 1 to 2 m³ range and the unit is installed safely.
Does it come with a thermostat?
Yes, it has a built-in thermostat for setting the target water temperature.
