Power Vent Water Heaters

Power vent water heaters use an electric blower to push the combustion gasses outside. There’s a bit more noise from the motor, but if your water heater is in your basement you shouldn’t notice it.

  • EnergyStar qualified models available, with a 0.70 EF, the best energy efficiency available in a hot water tank (except 60 and 75 gallon model).
  • 40 – 75 gallon capacity tanks available.
  • Gas input of 40,000 – 76,000 BTU per hour.
  • Safety system shuts down unit when flammable vapours are sensed and prevents vapours from entering the combustion chamber before shut down.
  • Advanced self-diagnostics.
  • Great choice as a replacement hot water tank, and many venting configurations are possible.

In many homes, gas vents from the basement are boxed in and take up space, often in the kitchen. If both the furnace and water heater are power vented, the lines are much smaller and that space can be reclaimed.
