Non Condensing Tankless Water Heater Venting

Non condensing tankless water heaters vent away the excess heat produced during the heat exchange process causing less corrosion and deterioration of the water heater and resulting in a longer life span.

Non condensing tankless water heater venting. Our high efficiency plus rl models offer rinnai s most advanced technology in non condensing tankless water heaters. They can achieve efficiencies of up to 98 percent. 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. The exhaust gasses are a much higher temperature as they leave the unit and are vented directly instead of being looped back through the heater.

All of them unpleasant and some quite dangerous. Non condensing tankless water heaters typically transfer to the water only about 80 percent of the heat they generate. Many factors affect the actual performance of a water heater. In the condensation process the water resulting is acidic usally bwtween ph 3 to ph 5 and must be.

When it comes to high efficiency tankless water heaters no one comes close to matching the expertise and innovation of a. If a tankless water heater is not vented properly a number of things can happen. With higher efficiency ratings and groundbreaking designs our tankless water heaters feature non condensing and condensing technology and are part of a new era in water heating. The exhaust is a gas condensate that is highly acidic and corrosive to the venting so they require the right material.

Condensing tankless water heaters are inherently more efficient as the capture more of the heating energy and have much lower exhaust temperatures. With a condensing tankless water heater you don t need metal venting. As such they have only one heat exchanger. Compared to condensing water heaters that vents exhaust gasses inside the unit non condensing will immediately vent the exhaust gasses outside.

Designed and manufactured by navien to burn gas at higher efficiency than other system on the market. Npn series are the first and only non condensing tankless water heaters with a stainless steel heat exchanger to deliver unmatched durability and performance. It loses about 20 of the heat that helps the water become hotter. The exhaust vent can therefore be pvc or polypropylene and not metal a feature that lowers the cost of installation.

You ll enjoy the endless hot water and energy savings you expect with the addition of wi fi monitoring and recirculation technology for faster hot water delivery. Navitech stainless steel burner. With the lower exhaust temperatures it is possible to use inexpensive pvc venting materials.
