Boiler Types

Navien wall hung boiler installation and service

Wall hung Boilers

Wall hung boilers are also called condensing boilers. There are two types of wall hung boilers. The first type is called a combination or combi boiler. Combination gas boilers are the ideal solution for customers who need both hot water and whole home heat from one unit. Combination boilers are capable of producing heat and hot water within a single compact wall hung boiler design. Unlike conventional boilers, a combination gas boiler heats water only when needed, making it as environmentally sound as it is cost effective. There are also wall hung boilers which are heating only. Heating only wall hung boilers require an external water heater or an indirect tied to the boiler as a zone.

Triple Pass Boilers

A triple pass boiler is the most efficient style of oil boiler. A triple pass boiler utilizes additional exhaust passage ways to cool the exhaust and transfer more heat into the water which is heating your home. Triple pass boilers are cast iron boilers with a life expectancy of 30 years. Most homeowners realize a significant fuel savings with a triple pass boiler, especially when it is paired with an indirect.

Conventional Boilers

Conventional boilers can be fueled from either gas (propane or natural) or oil. Typically these boilers are made from steal or cast iron and they have a life expectancy of 20-30 years. Conventional style boilers are usually responsible for both heating your home and your hot water. Hot water heating can be done two different ways. One option is to add a water storage tank called and indirect, this tank acts as a boiler zone and is the most efficient means of producing hot water from a boiler. The second option is called a tankless coil. A boiler with a tankless coil heats a metal coil within the boiler which the homes domestic hot water runs through. A tankless coil boiler must maintain its temperature all year. A boiler with an indirect can be setup as a cold start boiler which means it only fires when there is a call for heat or hot water. A tankless coil is considered contractor grade while an indirect is considered to be an upgrade.

About Forced Hot Water Boilers

A lot of home owners refer to their boiler as a furnace. A boiler is in fact a furnace, but a furnace is not a boiler. To differentiate between these two heating systems trades people refer to boilers as heating systems which push water and furnaces as heating systems which push air.

A boiler is a closed vessel in which water or other fluid is heated. A burner running on either natural gas, liquid petroleum or oil acts as the heat source. Heat is then supplied via copper or pex tubing around your home and is released through the process of convection. A boilers efficiency level is dependent upon multiple factors including owner operation, fuel type, venting, regular maintenance, and boiler design (i.e. thermostat & boiler controls). LeBlanc Heating installs and services all types of boilers from traditional to wall-hung combination systems. Some of the major brands we install include but are not limited to Navien, Viessmann, IBC, Utica, Weil Mclain, Thermoflo, Biasi, System 2000, Buderus, and Burnham. LeBlanc Heating also installs accessories and components such as thermostats, boiler controls, fittings, expansion tanks, control panels, air vents, pressure regulators, backflow devices, pumps, and other products to complete your radiant system.

What is Hydronic Air Heating?

Hydro air combines both forced hot water (A Boiler System) and forced hot air system components (Air Handler & Air Ducts). Copper tubing supplies hot water over an air handler which blows the warm air throughout your home's ductwork and into your conditioned spaces.

What is Radiant Floor Heating?

Radiant Heat systems require the installation of pex piping beneath your home's flooring. The piping transfers hot water (radiant energy) throughout the house which heats the flooring. The heat naturally rises from the floor and spreads to the air of the home. The benefit of radiant flooring is the concealed transfer of heat and even distribution. In addition to installation, LeBlanc Heating & Air Conditioning has a 24/7 service team which specializes in the maintenance and repair of forced hot water boiler systems.
