Water heaters are amazing devices. They make it possible to get your dishes sparkling, your white laundry whiter, and to come home on a cold day and take the steaming hot shower that makes you feel human again. Replacing a standard water heater with a high-efficiency water heater will make a homeowner's hot water last longer and save them money on their energy bill, while also making the household more environmentally friendly.

One of the big differences between standard and high-efficiency water heaters is that standard heathers use metal atmospheric vents, while high-efficiency heaters require vents made from PVC. In most cases when a high-efficiency water heater is being installed to replace a standard one, the metal venting must be ripped out and thrown away because it is not up to code. This is costly and environmentally detrimental because the used vent goes straight to the landfill. If there were a way to seal existing metal vent to meet high-efficiency vent standards, homeowners would not face these installation barriers. Can you help us refit standard water heater vents to meet sealed requirements for high-efficiency water heaters?
