Replace Your System Or Just Upgrade It

Whole Home Tankless

Install a MODEL 3 Water Heater in your home or business for endless hot water. The MODEL 3 works well in new construction and in older homes as a replacement to any gas or electric tank-type or tankless water heater. Since the unit is compact and doesn’t require venting, it can be placed almost anywhere.

Point-of-use Tankless

A MODEL 3 can be installed in a single location to provide immediate hot water or several units can be installed throughout the home or business for faster hot water at each location. You will save energy and waste less water. 

In-Line Remote Booster

Tired of waiting for your water to get hot? Install a MODEL 3 (or several) downstream of your existing gas or electric tank-type or tankless water heater for hot water in seconds. Once the incoming water has reached a temperature greater than the setpoint of the MODEL 3, our unit powers down and lets the existing unit provide the hot water. You’ll save time, money and energy.

In-Line Extender

Never run out of hot water again. Install a MODEL 3 on the outlet side of your existing electric or gas water heater. It acts as a backup booster, only powering up when your existing system is unable to keep up with your household demand. Plus, when your tank eventually fails or runs out of hot water, you will still have a backup hot water source.

In-Line Turbocharger

Reduce wear and tear as well as your energy costs by adding a MODEL 3 to your existing water heating system. Simply set your existing unit to a lower temperature and let the MODEL 3 “turbocharge” the incoming water to the higher setpoint temperature.

Solar Hot Water Booster

Just think of all of the options — log cabins, campgrounds, mobile showers. The MODEL 3 can take the warm water created by your existing solar panels and heat it to your desired setpoint. It can also help to extend the length of your shower.
