Standard, Cascade & Super Cascade

Standard residential electric water heaters have a factory-installed heat trap. It helps reduce the migration of hot water, thus limiting heat loss escaping through inlet and outlet fittings.Cascade and Super Cascade models are designed with a cold water inlet at the bottom of the tank. They allow you to get 10% more hot water compared to traditional top entry water heaters.

Gas

Atmospheric Vent

For atmospheric vent water heaters, air is drawn from inside the home and the exhaust is vented into a chimney. This heater features FVIR technology, which prevents the ignition of flammable vapours (including aerosols, solvents, gasoline, paint, paint thinner and lacquer). This water heater also features: a glass-lined tank, heavy-duty anode rod, and a thermostat that allows for easy temperature adjustments. Maintenance is simple with an easy-to-access combustion chamber and conveniently located drain valve.

Atmospheric Vent with Powered Damper

This atmospheric vent water heater uses its flue damper to increase efficiency by automatically opening and closing the vent to reduce heat loss in standby mode. Environmentally-friendly insulation and factory-installed heat trap nipples also reduce heat loss for maximum energy savings. This tank also includes a heavy-duty anode rod.

Note, power is required for this model.

Power Vent

A power vent water heater is used when conventional chimney venting is not an option. Air is drawn from inside the home, while a motorized blower forces the exhaust outside. This water heater features: factory-installed heat trap nipples, sensor to detect flammable vapours, state-of-the-art electronic gas control, and flexible venting options. This unit is ideal as a replacement water heater in a variety of applications due to its 3-position rotatable blower.

Power Direct Vent

A power direct vent water heater is ideal when inside air can’t be used for combustion, and a longer vent run is required. The air is drawn from outside using a pipe, and a motorized blower forces the exhaust outside. This water heater features: a sealed combustion chamber; factory-installed heat trap nipples; flexible venting options; a compact design for tight spaces, which makes it suitable for closet installations; and a conveniently located temperature and pressure relief valve, drain valve, junction box and anode rod, which allows for easy maintenance.
