Gas Water Heater Exhaust Temperature

Soon it is raining inside your chimney.

Gas water heater exhaust temperature.

Gas fired heating appliance no draft hood. Exhaust temperature o f o c chemical oxidation. Smith power vent gas water heaters are equipped with an electric blower fan that is installed on top of the water heater which requires an electrical outlet to be close to the water heater. The remaining heat creates a hot exhaust gas that requires metal venting typically stainless steel or thick aluminum.

On the other hand the epa suggests turning the thermostat down to 120 to reduce power consumption and a booster heater to reach sanitizing temperatures at select outlets. The blower pushes the exhaust and excess heat through the exhaust venting. The function of these fins on the gas water heater flue vent connector is to try to increase the transfer of heat from the water heater exhaust into the surrounding area maybe to make it warmer in a fantasy that we re cutting heating cost by exracting heat perhaps in hope of preventing frozen pipes nearby. Because of the cold conditions inside the oversized chimney the water vapor condenses inside the chimney.

The ulc s636 standard allows the material to exceed the limit for cpvc piping by 10 degrees fahrenheit. It is reasonable to assume that higher in the flue temperatures are much lower. Water heaters are factory set at osha recommended levels around 140 degrees. The difference is that a power vent water heater pulls in combustion air from the space around the appliance then uses a fan to propel the exhaust through the vent.

Orphaned water heaters vent into colder chimneys. C up to and including 110 c 230 f this temperature limit was intended to allow the use of polypropylene pp pipe for use as a flue gas material. Non condensing tankless water heaters typically transfer to the water only about 80 percent of the heat they generate. With a condensing tankless water heater you don t need metal venting.

The venting can run either vertically or horizontally with a longer line to help with space and sizing issues within your. The temperature in the pipe manufacturer technical data is 180 f. Liquefied petroleum gas fired heating appliance with draft hood. At the hottest point in a gas water heater flue the flue vent connector right above the heater top the temperature is not likely to rise above 350 degf.

The exhaust from the combustion of natural gas contains massive amounts of water vapor.
