Spa Heater 3kW

Recommended for frost protection and as a supplementary heat source for hot tubs (spas) with a capacity of up to 1,000 liters.
The heater features a built-in flow switch that automatically disconnects the heater if water circulation stops. Suitable for both indoor and outdoor use. When used outdoors, the heater must be placed in a dry and covered location, and a thermal cover is recommended to minimize heat loss.

Heating Performance:
In a hot tub with a capacity of 1,000 liters, the water heats by approximately 1.0°C per hour, assuming the hot tub is covered with a thermal cover and the ambient temperature is between +2°C and -5°C. Under ideal conditions, the heater can raise the water temperature to 45°C.

Installation:
This is a professional-grade unit delivered without a plug. Installation must be performed by a certified electrician experienced in hydrotherapy systems.

Notes:

1. Use a thermal cover to minimize energy consumption and maintain water temperature.
2. Ensure the heater is protected from weather conditions when used outdoors.
