Your Gas-Fueled Tankless Water Heater: Key Venting Factors

Your Gas-Fueled Tankless Water Heater: Key Venting FactorsMany homeowners are making the switch to tankless water heating in their homes these days. A tankless water heater can provide big energy savings because it doesn’t need to expend fuel keeping a tank of water hot constantly. Tankless units can provide a continuous supply of hot water on demand due to their unique design, which heats water instantaneously. The tankless water heater is also a space-saver, taking up much less room than a standard tank model.

Tankless water heaters that are fueled by gas use high-powered burners to provide hot water immediately when needed, so correct venting design and professional installation are extremely important. Be sure to consult a quality HVAC contractor in advance of purchasing your water heater(s). An experienced technician can determine whether a larger diameter gas pipe is needed and help you decide whether any additional point-of-use tankless units are necessary.

Direct, Dedicated Venting Required…

  • To keep your family safe: Shortcuts in tankless water heater venting may allow dangerous carbon monoxide leakage.
  • To keep equipment in top shape: Improper venting impedes performance and shortens your unit’s life because it allows condensate to enter and damage the unit.
  • To keep property protected: Careless venting practices can, for instance, result in condensate damage in chimney masonry.

Tankless Water Heater Venting Specifics

  • Your tankless water heater(s) may vent through the wall or roof.
  • Only UL listed stainless steel venting pipes are effective: They can stand up to contact with condensate and positive pressure from the water heater fan.
  • Vent runs must be relatively short: This minimizes installation costs and protects the water-heating unit. Follow manufacturer instructions and configure the venting system with few or no elbows, which shorten the maximum pipe run.
  • If using a masonry chimney: Line it with vent piping to accommodate condensate drainage.
  • Horizontal vent pipe must be sloped: Install the pipe sloping away from the tankless unit, with condensate drainage no further than three feet from the connection.
  • Prevent carbon monoxide leaks by sealing the venting system.
