Please note, the element cover is no longer used on the 1650 watt units. It is shown in the video, but that part has been discontinued.

We also now offer an add on option that will give you the air temperature at the heater location, this way you can monitor your water and air temps at any given moment.


The 1650 watt 120 Volt ac heater uses 13 amps.

The 5500 watt 240 volt ac heater pulls just under 23 amps but has great water heating abilities. This heater can also be run on 120 volt AC power. It will draw the same 23 amps but has a heating power of 2750 watts. 

Here are the full specs of each heater.

The 1650 watt heater produces 5400 BTU's and will raise the temperature of 648 gallons of water 1 degree F per hour. Please note, this does not account for the heat lost from your system.

Please note, for the 5500 Watt unit, the plug for this heater is not supplied with the heater, as there in not a true standard for the plug. You will need to provide and have installed by a licensed electrician the plug that attaches to the unit as well as the wall plug. The plug you need will need to be 240 Volt AC 30 amp. Alternatively you can have the unit hard wired in, which is how we have installed our own. For the 2750 watt heater, you can hard wire or add a 30 amp plug for 120 volt power.
