Features
- Helical Coil Heat Exchanger
- The Cyclone Mxi line features a spiral heat exchanger that is positioned in the center of the unit for uniform heat distribution. It also allows the combustion gases to stay in the tank longer, lengthening the heat cycle and providing higher efficiency.
- PermaGlass® Ultra Coat™
- The tank has been coated using an industry exclusive glassing process where the coating is applied as a liquid and then mechanically rotated to ensure an even coat that provides protection against corrosion.
- Fully Modulating Combustion
- Modulating the burner results in higher operating efficiencies and longer service life by adjusting the firing rate as the demand changes.
- Powered Anodes
- All Cyclone Mxi models come with a titanium powered anode. A Powered anode works in all water conditions and never need replacing. It eliminates the possibility of odors usually related to standard anodes.
- User-Friendly Electronic Interface
- The intelligent control system, with easy to navigate menu, provides precise temperature control and unit operating information.
- Venting Versatility
- The Cyclone MXI line can be vented vertically or through a side wall. They can also have separate venting for the intake and exhuast or by using a concentric venting assembly.
- iComm™ Compatible
- These heaters are compatible with the iCOMM™ module, allowing them to be monitored remotely.

Medium
Medium
Medium refers to the substance that carries heat through the heating system. Systems are either designed to use either Hot Water or Steam as a medium, and components are usually specific to one or the other.
Hot Water
Fuel Type
Fuel Type
To create heat, some form of fuel is required. Fuel Type specifies what the product uses as an input to create heat.
Natural Gas
Combustion Type
Combustion Type
Condensing appliances use leftover thermal energy from combustion gases to heat water in a secondary heat exchanger, resulting in higher efficiency and lower exhaust temperature.
Modulating
Vent Type
Vent Type
Products that use combustion (burning) of fuel to create heat also create potentially dangerous gasses that need to be exhausted (AKA "Vented"). Depending on the product, venting can be done via a chimney, through a side wall, or use a second vent to provide fresh air to the appliance.

Ultra Low NOx Emissions
Ultra Low NOx Emissions
NOx is a byproduct of the combustion process, and it's output is regulated in some jurisdictions. Many regulators mirror SCAQMD rules, which regulate air quality for some parts of Southern California. Ultra Low NOx appliances emit less than 10-14 ng/J (nanogram per Joule) of NOx. Learn More
