We have a very reliable selection of water heaters; both gas and electric. Our immersion heater materials are titanium, so do not corrode in seawater. They can be used in ponds and tanks and for industrial electric heating applications where heater elements need to be chemical resistant.
500 watt heater with control
For small tanks, we have 100 watt and 500 watt stainless steel heater elements with built-in thermostat controls.
Fully submersible, 32C maximum setting, stainless steel, 500 watt heater element with built-in controller and setting adjustment.
Electronic thermo controllers
Immersion heaters plug into these wall mounted temperature control boxes. A PT100 sensor probe connects to the tank to control temperature and provide the temperature on the control panel. Volt and Amp meter readouts give an indication of the load being used. Temperature is set by a dial control to the desired temperature. Single phase and three-phase units are available.
We can also assemble controllers with local materials. There are cheaper than the above, but of a simple design.
