Non Condensing Tankless Water Heater Venting

It loses about 20 of the heat that helps the water become hotter.

Non condensing tankless water heater venting.

They can achieve efficiencies of up to 98 percent. 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. 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 is a gas condensate that is highly acidic and corrosive to the venting so they require the right material.

With the lower exhaust temperatures it is possible to use inexpensive pvc venting materials. When it comes to high efficiency tankless water heaters no one comes close to matching the expertise and innovation of a. As such they have only one heat exchanger. All of them unpleasant and some quite dangerous.

Npn series are the first and only non condensing tankless water heaters with a stainless steel heat exchanger to deliver unmatched durability and performance. Compared to condensing water heaters that vents exhaust gasses inside the unit non condensing will immediately vent the exhaust gasses outside. The exhaust vent can therefore be pvc or polypropylene and not metal a feature that lowers the cost of installation. Non condensing models are the more basic form of gas powered tankless water heater.

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. With a condensing tankless water heater you don t need metal venting. In the condensation process the water resulting is acidic usally bwtween ph 3 to ph 5 and must be. 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.

Many factors affect the actual performance of a water heater. Navitech stainless steel burner. Condensing tankless water heaters are inherently more efficient as the capture more of the heating energy and have much lower exhaust temperatures. Non condensing tankless water heaters typically transfer to the water only about 80 percent of the heat they generate.

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. If a tankless water heater is not vented properly a number of things can happen. Designed and manufactured by navien to burn gas at higher efficiency than other system on the market.
