Gas Tankless Water Heaters

Available15 products
Gas tankless water heaters produce a continuous supply of hot water as needed reducing energy usage. These gas-powered heaters, also called instantaneous or on-demand, use natural gas or propane to heat the water. Tankless water heaters have a smaller footprint well suited where space is limited and can be installed indoors or outdoors.

High-Efficiency Indoor Commercial Gas Water Heaters

High-Efficiency Indoor Commercial Gas Water Heaters

High-efficiency (HE) water heaters include a secondary heat exchanger that maximizes the heat transfer process to extract as much heat energy (Btus) as possible without a lot of waste. These gas water heaters are rated for indoor use and extract heat energy out of the exhaust gases to heat the water. HE commercial gas water heaters have higher thermal efficiency ratings than standard water heaters.

Standard Efficiency Indoor Residential Gas Water Heaters

Standard Efficiency Indoor Residential Gas Water Heaters
Standard efficiency residential gas water heaters meet the daily demands for hot water. These residential units meet the demands for continuous hot water with lower maximum heating capacities and lower maximum flow rates. These tankless indoor units use direct venting by pulling in air from the outside. The combustion fan blows exhaust from the heater horizontally and vents to terminate on a side wall.
