Why Sealed Combustion Closet is Essential for Safe Home Air

Why Sealed Combustion Closet is Essential for Safe Home Air

If your Peachtree City home has a gas furnace or water heater inside, you may not realize that the equipment can pose a hazard to your family’s health and safety. To ensure you have a healthy, safe home air supply, it’s vital to learn about this potential risk and why a sealed combustion closet is the solution.

Why Combustion Equipment May Pose a Safety Risk

Furnaces and water heaters are commonly installed within the conditioned envelope of a home, so they get the air needed for combustion from the surrounding room. They’re also vented outdoors to allow exhaust fumes to exit. An installation setup like this can pose two serious threats to your family’s safety:

  • Water heater exhaust backdrafting. When combustion air is being drawn from inside the home and expelled outdoors, negative pressure can pull hazardous fumes back down the exhaust pipe. This can lead to incomplete fuel combustion in the appliance’s burner, and send life-threatening carbon monoxide into your home’s air supply.
  • Loss of a critical furnace safety feature. If your water heater’s vent pipe is connected to your furnace flue and it becomes blocked, the sensor in the furnace may not accurately detect the resulting increase in pressure and shut off the unit for safety. This can let hazardous trapped exhaust fumes backdraft down the water heater’s vent pipe.

A Sealed Combustion Closet Solves the Problem

Enclosing the furnace and water heater in a sealed combustion closet can prevent potential backdrafting. To be effective, such a closet must:

  • Be completed sealed and self-contained so air can’t enter the surrounding room.
  • Have a weatherstripped access door with a tight threshold to stop any air leakage.
  • Have any wall or ceiling penetrations properly air sealed.
  • Be equipped with two combustion air inlets – one that terminates a foot from the floor, and the other a foot from the ceiling.
  • Have air inlets sized according to the equipment capacity – with a square inch of inlet size per 4,000 Btu of equipment input capacity.

Water Heater Sediment Impacts Performance — Remove It Before It Does

Water Heater Sediment Impacts Performance -- Remove It Before It DoesWhether your water heater is gas-powered or electric water heater sediment can impact its performance. In the case of a gas water heater, that can mean efficiency is reduced to 60% or lower. In an electric water heater, sediment build-up can cause the heating element to burn out. A thorough cleaning, however, can return your electric water heater to 99% efficiency. To maintain proper efficiency of your water heater, experts recommend having it flushed every six months.

While it is possible to remove water heater sediment yourself, it never hurts to seek professional assistance. The first step is to turn off the water and energy supply to the tank. For an electric tank you will need to turn off the breaker. For a gas-powered water heater note the temperature setting of the gas dial and then turn it down to “pilot.” This will turn off the heat without extinguishing the pilot light.

Next, locate the drain valve. The valve should be located near the bottom of the water tank and in some cases may be located beneath a cover. Once the valve has been located, attach a hose to the valve. Run the other end of the hose to the nearest drain location. If there is not a drain nearby, it may be necessary to use a bucket to carry the water away.

Once you have drained the water—and hopefully the sediment, too—turn the water supply back on. If there is still sediment left in the water tank, you may want to flush it again.When you are satisfied, close the valve, remove the hose and allow the water heater to refill before turning the heat source back on.
