Low NOx commercial water heaters are required in Texas and ultra low NOx water heaters are required in most of California.
Why is NOx bad?
NOx can cause serious health damage to humans, including respiratory diseases. NOx is also responsible for smog and the typical brown cloud that covers larger cities and produces poor air quality. NOx reacts with volatile organic compounds in the presence of sunlight and forms ground-level ozone.
Why is NOx low?
Zero emissions: The new Low Nox and Ultra-Low NOx standards are meant to make gas furnaces more environmentally friendly by reducing the amount of harmful greenhouse gasses they emit. Ultra-efficient: Unlike a furnace, a heat pump doesn’t burn fuel to make heat.

Where are ultra low NOx furnaces required?
Counties and areas where 90% condensing and 80% non-condensing gas furnaces must meet the 14 ng/J NOx limit requirement. Counties and areas where 90% condensing and 80% non-condensing gas furnaces must meet the 40 ng/J NOx limit requirement.
What does AFUE stand for?
Average Fuel Utilization Efficiency
December 12, 2018. While an air conditioner’s efficiency is measured by its SEER (Seasonal Energy Efficiency Ratio) rating, an electric or gas- or oil-fired furnace’s efficiency is measured by its AFUE, or Average Fuel Utilization Efficiency.Dec 12, 2018
Does BTU matter water heaters?
Recovery of gas-fired water heaters is a function of the BTU input and overall efficiency. A common input is 34,000 BTUs on a 40-gallon tank and 36,000 BTUs on a 50-gallon tank. The higher the BTU input and efficiency, the faster the recovery.Mar 23, 2021
How do ultra low NOx burners work?
Today’s ultra low NOx boilers use advanced technology and methods to reduce NOx emissions. Low NOx burners are designed to control air and fuel mixing at each burner, which creates more branched and larger flames. By reducing the peak flame temperature, significantly less NOx is formed in the process.
What does BTU mean for water heaters?
British Thermal Units
Input – The amount of gas or electricity used per hour to heat water in the tank. Higher input means the water heater can heat more water faster when needed. Natural or propane gas input is expressed in BTU’s (British Thermal Units) per hour, and State gas inputs range from 30,000 to 75,100 BTU’s.
What is a self cleaning water heater?
The self-cleaning water heater automatically circulates the water to reduce the sediment build-up. It is equipped with a fitting on a curved dip tube that swirls the water at the bottom of the tank. This stirs the sediments in the water that come out through a hot water outlet whenever you use hot water.Jan 28, 2021
Can NOx kill you?
Also emitted in diesel fumes are solid particles which can penetrate deep into the lungs and cause cancer, chronic breathing problems and premature death in people with heart or lung disease.Sep 23, 2015
Which is worse CO2 or NOx?
While diesel engines emit LESS CO2 than their petrol equivalent, they emit MORE NOx. The very things that make diesel engines produce less CO2; high combustion temperatures and lean burning, in turn produce higher levels of NOx. More diesel engines brought down CO2 emissions significantly, but increased NOx levels.
Can you smell NOx?
NOx is produced from the reaction of nitrogen and oxygen gases in the air during combustion; especially at high temperatures. Nitrogen dioxide (NO2) is a reddish-brown gas with a pungent smell. NOx (NO & NO2) can irritate the lungs, cause bronchitis and pneumonia, and lower resistance to respiratory infections.
Is nitrogen an oxide?
Nitrogen Dioxide (NO2) is one of a group of highly reactive gases known as oxides of nitrogen or nitrogen oxides (NOx). Other nitrogen oxides include nitrous acid and nitric acid.Sep 8, 2016
