Baptistry Heaters

Immersion Heater

The ChurchRite Immersion Heater is both economical and simple to use. No plumbing or installation required, this baptistry heater is portable and is designed to be mounted over the side of the baptistry with included stainless steel mounting brackets. A 60″ power cord is included as well as a built in thermostat. When desired water temperature is reached, simply remove the heater and store during baptismal services.

A 120 volt model is available for smaller baptistries and a 240 volt model is available for larger baptistries, or multiple small models can be used. We offer models with a built in GFCI and without, though the heater must be plugged into a GFCI outlet is the model is chosen without the built in feature. All models come with a one year, limited manufacturer’s warranty. The ChurchRite Immersion Heater must be in water when in use to avoid “dry burn” which incapacitates the unit and is not covered under the warranty.

Installation and Operating Instructions

WARNING: Never turn on heater unless baptistry is full of water.

  • Fill baptistry with water to required level. The water level must be at least 12” below the control box. The control box should NEVER be immersed in water. Also, the lower 24” of the heater must be immersed in water when it is turned on or it will overheat and burn out, cause bodily harm or become a fire hazard. Burned out heaters are NOT covered by warranty.
  • Mount the heater into the baptistry, securing it using the brackets provided with the heater unit. The unit can be mounted in the middle, end or side of the baptistry. The heater must be securely mounted to prevent the electrical box from making contact with the water.
  • Plug the heater into the correct receptacle and set desired baptistry temperature on the thermostat dial. The signal light glows only when the heating element is energized. When the desired temperature is reached the signal light will be off.
  • CAUTION: Prior to the baptismal service the baptistry heater must be turned off, unplugged and removed from the baptistry. This will guarantee protection from the danger caused if an electrical short circuit were to occur in the heater electrical system.

Instruction for Removing the Heater from the Baptistry Water

Note: Remove the immersion heater before entering the baptistry.

  • Turn the thermostat off (shown as LO on dial).
  • Unplug the heater from the electrical source.
  • Wait at least 2 minutes before removing the heater from the baptistry, allowing the heating elements to cool.
  • After the removal of the heater you can then drain the baptistry. DO NOT DRAIN BEFORE REMOVAL.

Maintenance Schedule

  • Chemical Use: Overheating of the elements can happen due to minerals building up. To remove these minerals simply wipe the heating rods of the heater down with normal household white vinegar. This should be done every 90 days. The immersion heaters allow should never come into contact with any with any alkaline solutions such as Chlorine or Bromine.
  • Caution: Under NO circumstances should this heater be turned on unless the system is full of water. Without water the heater rod can burn out quickly and also damage the thermostat control. The warranty is void under these circumstances and we will assume no responsibility for damage to the heater, associated equipment or other damages.
  • Hi-Limit: If the thermostat should fail and its contacts stick in a closed position, the heating element will continue to heat the baptismal water to about 117 degree F (120V model) and 125 degrees F (240V model). At this temperature the Hi-Limit will open and turn the heating element off. After repairing or replacing the thermostat the Hi-Limit can be manually reset.
  • Important: Before using the heater the mounting bracket must be installed properly to ensure that the heater sits over the side of the baptistry correctly.
