Gas Water Heater Exhaust Temperature

The blower pushes the exhaust and excess heat through the exhaust venting.

Gas water heater exhaust temperature.

It is reasonable to assume that higher in the flue temperatures are much lower. 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. Gas fired heating appliance no draft hood. 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.

The process of burning of the gas is called combustion and it creates heat exhaust gases including highly poisonous carbon monoxide and moisture the water heater s ventilation system removes these byproducts from the home making it a critical safety feature. The ulc s636 standard allows the material to exceed the limit for cpvc piping by 10 degrees fahrenheit. Liquefied petroleum gas fired heating appliance with draft hood. The venting can run either vertically or horizontally with a longer line to help with space and sizing issues within your.

The exhaust from the combustion of natural gas contains massive amounts of water vapor. Orphaned water heaters vent into colder chimneys. With a condensing tankless water heater you don t need metal venting. Non condensing tankless water heaters typically transfer to the water only about 80 percent of the heat they generate.

Exhaust temperature o f o c chemical oxidation. Soon it is raining inside your chimney. Water heaters are factory set at osha recommended levels around 140 degrees. Natural gas fired heating appliance with draft hood.

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. 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. All water heaters that burn natural gas or liquid propane lp gas require a venting system.

Because of the cold conditions inside the oversized chimney the water vapor condenses inside the chimney.
