Gas Water Heater Exhaust Temperature

Exhaust temperature o f o c chemical oxidation.

Gas water heater exhaust temperature.

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. 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. Orphaned water heaters vent into colder chimneys.

Natural gas fired heating appliance with draft hood. 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 blower pushes the exhaust and excess heat through the exhaust venting. The venting can run either vertically or horizontally with a longer line to help with space and sizing issues within your.

The ulc s636 standard allows the material to exceed the limit for cpvc piping by 10 degrees fahrenheit. Water heaters are factory set at osha recommended levels around 140 degrees. The remaining heat creates a hot exhaust gas that requires metal venting typically stainless steel or thick aluminum. 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.

Because of the cold conditions inside the oversized chimney the water vapor condenses inside the chimney. Non condensing tankless water heaters typically transfer to the water only about 80 percent of the heat they generate. Soon it is raining inside your chimney. The temperature in the pipe manufacturer technical data is 180 f.

All water heaters that burn natural gas or liquid propane lp gas require a venting system. 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. Gas fired heating appliance no draft hood. 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.

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