## Description

desertcart.com : Mxmoonant 2KW 110V Hot Tub Thermostat, Spa Heater BathtubThermostat | 0-45℃ Temp Control, 1.5" PVC Plumbing Constant Heating for 400Gals Whirlpool Bathtub, Hot Tub, Spa, Small Pool (No Plug) : Patio, Lawn & Garden

## Features

- 1.5" PVC Plumbing Standard]: The heater includes 1.5" SCH40 PVC fittings. Ensure all plumbing connections match this diameter for optimal flow. Important: If adapting pipe sizes, the heater’s inlet/outlet must remain 1.5"—reducing pipe diameter elsewhere may compromise water circulation efficiency.
- [Circulation Pump Requirements]: Spa heater must be paired with a circulation pump rated ≥0.5HP (booster pumps or submersible pumps are incompatible). Note: Pumps below 0.5HP may fail to activate the heater due to inadequate water pressure. Always verify pump specifications before installation.
- [Constant temp control]: Set and maintain the desired water temperature from 0 to 45°C using the temperature knob. The hot tub thermostat continuously monitors and adjusts the operation of the heater to maintain the water at a constant temperature once the desired temperature is set.
- [Heating Tips]: For faster heating, fill the tub with hot water instead of cold, keep the water volume under 400 gallons, and use an insulation cover to maintain temperature. Starting with cold water or exceeding the capacity may result in slow heating or failure.
- [No Plug Supplied]: As the pool thermostat is a high power device, it is not supplied with a plug. It should be connected to a 25 amp GFCI circuit breaker. We recommend using a professional electrician to connect the circuit.
