## Description

desertcart.com : Mxmoonant 2KW 110V Hot Tub Thermostat, Spa Heater Whirlpool Bathtub Thermostat with Adjustable Temp Control for 400Gals Bathtub, Hot Tub, Spa, Small Pool (No Plug) : Patio, Lawn & Garden

Review: Works great! - Made myself a HotTub setup and man this thing did not disappoint!!
Review: Nice heater for hot tub or small water. - Works great easy to install. last about a year or 2 but that's all I've gotten out of any heater.

## 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.

## Questions & Answers

**Q: Why no plug but need to be wired?**
A: The pool thermostat does not come with a plug as it is a high power device. It should be connected to a 20A GFCI circuit breaker. It is recommended that you find a professional electrician to complete the circuit connection.

**Q: How to do plumbing connections?**
A: You have to use SCH 40 1.5" PVC pipe for the plumbing connection. A smaller size may result in insufficient water flow. If you want to use other pipe sizes, please note that everything should start with 1.5".

**Q: What kind of pump should I connect to?**
A: Spa heater have to connected with circulation pump with power of more than 0.5HP rather than booster pump or submersible pump. Smaller pumps may not provide enough water flow to activate the heater.

**Q: Any tips for heating?**
A: It's recommended to fill the hot tub with hot water instead of cold water and the water capacity to no more than 400 US gallons and to use an insulation cover to retain the temperature. Otherwise, it may take a long time or may not heat up at all.
