Residential Gas Boiler Service

Gas boilers work by burning a fuel source, such as natural gas or propane. The heat from the flame is transferred to cooler water running through a pipe inside the boiler. The newly heated water exits the boiler and runs through a series of pipes in your house, such as a radiant heating system. Once the heat is transferred to your home, the now cooled water returns to the boiler system to repeat the process. The most inefficient process in boiler operation happens when the combustion gases (exhaust) leave the house through the flue. This is wasted heat that passes by the heat exchanger in the boiler as heat is transferred to the cool water at the beginning of the process. J and L Mechanical recommends using an energy efficient  boiler, which effectively reuses the flue exhaust to heat the water in the boiler.

Gas Boiler Maintenance

Routine maintenance can keep your boiler running at its peak efficiency. Keeping your system running as efficient as possible is important to your pockets. The higher the efficiency of your boiler the more money you will save on your monthly utility bills. Regular maintenance can also spot potential problems before they turn into problems.

Gas Boiler Repair

Boiler systems are very durable and long lasting but like any other system problems can arise. Common boiler problems include:

  • Power not reaching boiler
  • Low water level
