Rinnai Ducted Gas Heating

What is Ducted Gas Heating?

Ducted gas heating is one of the most powerful, affordable and versatile ways to heat up the home. It is a type of heating system that heats up cold air that has been pulled into the gas heater, and distributes it through flexible ducts and vents to warm up the home. The heating unit is usually stored in the roof space or outside the home. It is connected to a network of ducts and vents that are placed in either the ceilings or the floor of your home.
