Gas Hot Water Boilers - Campbell Heating & Air Littleton MA

For those in Massachusetts who need information about Installing, Servicing, or Repairing a Gas Hot Water Boiler here is some helpful information from a local Littleton, MA HVAC:

Gas Fired Hot Water Boiler
A hot water boiler is an appliance used to heat water for a hydronic heating system. The hot water is distributed through the home in pipes and radiate heat into the rooms with either a steel radiator (newer homes) or cast iron radiator (older homes) or baseboard convectors or "fin-tube" (newer homes). Once the radiator or baseboard fin-tube convector is heated with the hot water, the water is returned back to the boiler to be re-heated and the water circulation loop continues. In addition to radiators, the hot water boiler is also used with radiant floor heating systems.

These boilers can be fueled either with natural gas or propane (gas-fired) or they can burn fuel-oil (oil-fired). Fuel-oil boilers are higher maintenance than their gas burning counterparts and require regular attention to the blower and oil filter.

Components of a Hot Water Boiler
The boiler is more complex than a forced air furnace in that it has more parts, valves and controls. However gas-fired boilers are fairly reliable and most problems, when they do occur, usually relate to the expansion tank or water circulator pump(s).

Let's take a quick look at the major components of the boiler for a forced-water (hydronic) system:

Hot Water Supply Side:

Aquastat - The thermostat that regulates the boiler's temperature Gas Valve and Burners - Combustion assembly that heats the water chamber Combination Pressure / Temperature Gage (Tridicator) - Monitors water temperature and pressure Water Feed Valve - Controls water flow to boiler Pressure Reducing Valve - Automatically maintains correct water pressure at about 12-15 psi Air Vent - Automatically purges unwanted air from hydronic system Expansion Tank - Critical component that allows expansion of water as it heats. There are two types of expansion tanks, the older larger style horizontal steel expansion tank and the newer smaller style diaphragm expansion tank. Flow Control Valve - Regulates flow of hot water to system Pressure Relief Valve - Relieves high water pressure Hot Water Return Side: Circulator - Electric pump that circulates water through the system Drain Valve - Valve that opens to allow draining the boiler.
