Bath tub heaters will only maintain the water temperature in the bath. They will only heat the water approximately 1-2 degrees an hour.
Whatever water temperature you start with is what you will be able to maintain.
There is a red indicator light on the front of each heater indicating whether or not there is power to the unit when the tub is full of water and the water pump is turned on.
If there is a red light on then it has power to it and is working.
This heater will never feel warm to the touch.
There are three different styles of Bath Heaters available.
- Tee Heater - installs on the discharge fitting on the pump
- In-line Pressure - installs anywhere in the plumbing line before any jet.
- In-line Vacuum Heater - installs before the suction of the pump
If the heater you purchased is installed in the wrong place it will not operate.
