Condensing Tankless Water Heater Venting

The remaining heat creates a hot exhaust gas that requires metal venting typically stainless steel or thick aluminum.

Condensing tankless water heater venting. As i mentioned when you go for an electric you have way more options available. Tankless water heaters blow exhaust from the heater horizontally with the use of fans thereby permitting vents to end on a different position of your house. With the lower exhaust temperatures it is possible to use inexpensive pvc venting materials. With a condensing tankless water heater you don t need metal venting.

All residential models are energy star qualified and utilizes pvc venting. In the condensation process the water resulting is acidic usally bwtween ph 3 to ph 5 and must be. Condensation tankless water heaters minimize the value of the installation. Non condensing tankless water heaters typically transfer to the water only about 80 percent of the heat they generate.

All of the energy needed to heat the water stays there with no loss. They can achieve efficiencies of up to 98 percent. The exhaust vent can therefore be pvc or polypropylene and not metal a feature that lowers the cost of installation. Tankless water heaters with condensing technology are up to 95 more efficient than non condensing units and emit a comparatively cooler exhaust gas according to the propane education and research council.

Condensing tankless water heaters are inherently more efficient as the capture more of the heating energy and have much lower exhaust temperatures.
