Boiler Systems and Boiler Installation

Written by admin

Purchasing a boiler can be daunting for most people as many people do not understand boilers and do not know what certain components are with boiler systems. Typically they trust the installing contractor to outfit and install the boiler with all the proper boiler components including making recommendations for optional boiler components.  There are resources we can use to try to understand boilers and boiler components but overall this research or study will not make one an expert in boilers and boiler installation. We simply have to trust the boiler installer and the skills of the boiler contractor.

Important Points in New Boiler Installations

Depending on the installation, whether it is a new installation or a retrofit where the contractor is replacing an existing old boiler, it is very important that the boiler piping is correct or installed correctly especially the near boiler piping. Near boiler piping is the pipe near the boiler where most of major pipe components are located.  Near boiler piping components include:

• Flow valve
• Expansion tank
• Circulator pump
• Boiler air management and control devices
• Mixing valves (if the system is equipped with a mixing valve – usually a mixing valve is installed with a boiler that provides domestic hot water)
• Back flow preventer and pressure reducing valve on the make-up water supply
• Any zone valves if the hydronic loop is zoned

Near boiler piping is also where the water entering the boiler and leaving the boiler (boiler supply and return) make many turns and has elbows and a possible manifold installed. It is important that this system is set up and installed properly. If it is not then the poor installation can affect the efficiency of the boiler and sometimes it can cause problems with heating certain zones because a bad near boiler piping will cause a poor flowrate in the piping system. Additionally, pressure problems can occur and lead to noisy flow of the water. The whole boiler system will be problematic and cost you more in fuel to fire the boiler.

Probably the most important part of buying a new boiler is selecting the right contractor to install the boiler properly. A skilled contractor will save you a lot more money on a boiler installation than you will save on hiring someone who really does not know what they are doing and installs the boiler incorrectly. Find a good boiler installation contractor and spend some time selecting a good boiler that they recommend. It is advised because of the higher cost of fuels these days that you select a higher efficiency boiler as this will save you money in the future on your fule bills. Remember, even if you are selling the house in a few years select a higher efficiency boiler for the installation over a cheaper less efficient boiler. Why? Because it will add value to the sale of the home and it convinces the buyers they aren’t buying a house that will consume all their dollars in feeding a boiler fuel hog. Good luck on selecting the right boiler and boiler installtion contractor for your next boiler installation.
