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 types of boilers and those two categories are steam and hot water boilers. Either of those categories can be fueled by oil, gas, or electric (although electric is uncommon for steam boilers). They have different designs and piping configurations as a steam boiler system is designed to turned the water into steam and uses gravity and pressure to deliver the heat and the hot water boiler systems are designed to simply make hot water to be circulated (by a circulator or pump) through a piping system to provide heat. Typically, hot water boilers are more efficient than steam boilers for a few reasons. First, there is less heat loss throughout the hot water piping and the shell of the boiler because the hot water boiler operates at a lower temperature than the steam boiler. This means there is less heat loss throughout the entire boiler and piping system. Secondly, because the hot water boiler operates at a lower temperature, it requires less fuel or energy to convert into heat. What kind of boiler do you have in your boiler room?
Residential and Light Commercial Low Pressure Steam Boilers
The residential steam boiler is still alive and well despite the fact that some HVAC professionals refer to it and the steam boiler profession as the dead mans club. However, there are not a lot of HVAC boiler technicians or HVAC companies that specialize in steam boilers because there are not a lot of the steam boilers used for residential and light commercial applications. People have either converted their old boiler steam systems over to hot water or have gone with forced air systems. The concept is simple but the mechanics of it can be frustratingly complex when a problem occurs unless you have the experience and knowledge that comes with working on the residential or light commercial steam boilers. Before we dive into some of the problems that arise with steam boilers, we’ll cover safety first. After all, HVAC safety is the most important aspect to any home heating system.
Hurricane Irene was a disaster for us as we live in a Northern state that was hit by flooding from the rain of Hurricane Irene. As a result of the loss of power and the flooding our basement was flooded. Our boiler happens to be in the basement and we will soon need the heat. We have had a few contractors come by and look at the boiler with one contractor telling us we need to replace the boiler and another telling us we can rebuild the boiler. My husband is the do it yourself type and he wants to turn the boiler on and see if it will work and then go with it for the winter however I am concerned about the boiler and the safety issues. What do we do? My husband has agreed to follow your recommendation.
Thanks for you advice and you have a great site!
Hot Water Boiler Piping for a commercial boiler application. Boiler project being renovated and getting all new DDC controls for optimum hydronic control and efficiency. Boilers are an excellent way of providing good hot water heat to a large building or community. Some people refer to them as furnaces, hot water heaters, hot water heating systems, or hot water heater but the proper name is to call them hot water boilers. Hot water gas boilers provide clean draftless hot water heat through pipes and piping systems which HVAC professionals refer to as hydronic piping. Typically, hot water heating systems use pumps or circulators to move the water through the hot water piping system. Hot water heat is considered to be a good source of draftless heat by the people who have these hot water heating systems installed in their homes and businesses.

Hydronics refers to using water and for chilled water, steam boilers and hot water boilersand other methods of transferring heat using water. A boiler or chiller is used to heat or cool the water and then the water is transferred through the hydronic piping loops to heat exchangers such as coils or baseboards where heat is transferred from the water to the air for heating and from the air to the water for cooling to provide comfort for people or a process. Hydronics is very popular in commercial and industrial HVAC applications for heating and cooling occupants in large buildings and providing heating and cooling for for equipment and machines including computers and servers. Basically in a nutshell hydronics uses water to move heat from one place to another.
