Navien High Efficiency Condensing Boilers and Combi-Boilers

If you ever made your way through a frigid blizzard into the comfort of a warm home, you owe a debt of gratitude to a boiler. 

An efficient and powerful boiler is a crucial component for central heating systems and more. That’s why McCarver Mechanical Heating and Cooling recommends Navien High Efficiency Condensing Boilers for residential and commercial applications. 

For customers looking to heat both rooms and water, we also recommend Navien High Efficiency Condensing Combi-Boilers.

How Does A Boiler Work?

Boilers help make the steps between turning the heater on and enjoying comforting warmth seem easy. But there’s a lot of work going on.

  1. The user turns on the heater, opening a valve in the boiler through which gas enters a combustion chamber. 
  2. An electric ignition system ignites the gas entering the combustion chamber.
  3. The resulting flame warms cold water that’s in a pipe connected to the heat exchanger. 
  4. An electric pump moves the heated water through piping that wends its way around a house or office space. 
  5. As the heated water flows in the piping, it moves through radiators in various rooms and gives off heat that warms the space.
