Save Green by Going Green

Looking for an environmentally friendly product? The Combi Wall is for you! This ENERGY STAR ® certified boiler has an Annual Fuel Utilization Efficiency (AFUE) of up to 95% while homeowners with older gas furnaces may only be using as little as 60% of energy consumed. Heating is the largest energy expense in most homes accounting for 35-50% of annual energy bills in colder parts of the world.

With a Westinghouse high efficiency heater 95% of the dollar spent on heating is properly used to heat the home. That is real savings! Upgrade your existing heating system with the Combi Wall and see how much you can save!

The Combi Wall also has ultra-low NOx emissions providing additional environmental savings due to its combustion control system, which minimizes levels of nitrogen oxide. If NOx levels are not reduced, oxidants can build up in the atmosphere and have harmful effects on human health.

Built to Last

The Combi Wall is manufactured with the highest quality materials. The stainless steel fire tube heat exchanger is more resistant to corrosion in comparison to typical copper or aluminum heat exchangers. Stainless steel lasts longer and is virtually maintenance free, while also facilitating the transfer of heat more efficiently.

The fire tube design of the heat exchanger provides a greater efficiency and a lower pressure drop. The built in stainless steel indirect storage tank provides endless hot water and eliminates temperature fluctuation!

This revolutionary designed unit is available in both natural gas and liquid propane. It vents in inexpensive PVC, CPVC, or Polypropylene.
