How to Clean Gas Boiler Burners - Before beginning boiler maintenance or repair including cleaning the gas boiler burners on any boiler it is important to follow all safety procedures. Turn off the gas to the boiler at the gas cock located on the gas line and turn off the gas valve on the boiler. Additionally turn off the main power to the boiler at the circuit breaker. (more…)
Boiler Types - There are many different types of boilers in the boiler room today in a variety of heating applications. There are two main categories of boilers among the different boilers and those two categories are steam boilers and hot water boilers. Either of those categories can be fueled by oil, gas, or electric (although electric is uncommon for steam boilers). (more…)
Boiler Efficiency Options – High Performance HVAC wants to help you understand your next boiler purchase better. To do this we want to break down all the different types of boilers and components, and various options and features that you may find when making a purchase. Typically you want to find a like replacement for the boiler you currently have installed or if you are buying a new boiler you want a system that will handle the load and is durable. The most important feature about the new purchase is usually the fuel efficiency simply because the cost of running the new system will give you pay back over time for the new purchase.
Commercial Boiler Stack with Economizer - This is not a normal commercial boiler stack in this boiler room. It has a bypass stack for a commercial hot water economizer. All boilers have make-up water to make up for water lost in the systems especially for domestic hot water use. (more…)
Natural Gas Properties and Furnace Heating Efficiency
Natural Gas is a popular fuel used for heating systems in America and other countries. If we look at the properties of natural gas and the heating efficiency of natural gas furnaces we will see that natural gas furnaces lose efficiency because of what is contained in natural gas as it is delivered to your home for consumption by your natural gas furnace. Natural gas in its raw form coming straight from the ground needs to be refined to remove impurities that should not be contained in natural gas. As you read below you will see that in the refining process moisture is removed from the natural gas however during the refining process some of the moisture in the natural gas remains and therefore this affects the efficiency of your natural gas furnace. Condensing furnaces always have a drain on them to drain away one of the byproducts of combustion which is water/moisture contained in the gas. This is why it it is called a condensing furnace simply because it condenses all the moisture from the gas during the combustion process. I am certain there are people who have had a problem with a leaking furnace in the winter time where the drain became clogged or plugged and required someone to clear the condensation drain to clear the drain. This is the water that is condensed from the natural gas during the combustion process along with moisture contained in combustion air. Any moisture in the gas will affect the efficiency of the furnace. The less impurities in the natural the more efficiency you will get from the gas furnace.
