Gas Boiler Replacement & Installation in Newport News, Norfolk, Virginia Beach, Hampton, Chesapeake, Portsmouth

Gas Boiler Replacements and installations in Virginia

A boiler is designed so that water can flow around a heat exchanger that's made hot by burning gas, oil or some other type of fuel.

Like other gas-fueled appliances, a gas boiler can be adapted to burn natural gas or propane gas. Most gas boilers don't actually boil water; they just heat it. The hot water is then pumped to radiators, under-floor tubing, or to a heat exchanger. In a duct system, all of these heating systems are referred to as "hydronic" (water-based) heat.

Wall-mounted radiators and hot water baseboards use their boiler-supplied hot water to warm rooms by radiation and convection. Hot water circulating in under-floor tubing turns the entire floor surface into a giant radiator. A gas boiler can also supply a forced-air heating system (referred to as "hydro-air") with hot water for its heat exchangers.

A gas boiler that's more than 10 years old can be operating inefficiently even when functioning perfectly because, relative to modern high efficiency equipment, it was designed inefficiently.

Today, new gas boilers are available that operate at 90% efficiency or more. Dr. Energy Saver can evaluate your current heating system and provide a free quote on a super-efficient system that will save you money. Call or email today for a free quote.

A boiler can supply hot water just for whole-house heating; or it can supply hot water for heating as well as for washing. Either way, a gas boiler is described in the following ways:

  • BTU output. The heat output of a boiler is listed in thousands of btus (80,000btu, for example) and denotes the amount of heat energy the boiler can produce.
  • Annual Fuel Utilization Efficiency. A standard measure of efficiency for boilers and furnaces, AFUE tells you the percentage of input energy the boiler can convert to output energy.
  • Combustion. "Direct-vent," "sealed combustion" and "atmospheric combustion" boilers are available. Differences between the three types are discussed below.

Direct-vent boilers offer the best efficiency

If you have an older boiler, it will have a metal flue that is connected to a chimney. This type of boiler relies on natural "atmospheric" combustion. In contrast, a gas-fired, direct-vent boiler is designed to extract more heat from a given quantity of fuel. In fact, so much heat is extracted that the flue gases are cool enough to vent outside through a plastic pipe. No chimney is required. Direct-vent gas boilers will have AFUE ratings in the 85%-90% range —much better performance than you could expect from an older boiler that exhausts up a chimney.

Some direct-vent boilers not only vent directly to the outside through a plastic pipe; they also get their combustion air from outside the house. This "sealed-combustion" boiler is often recommended in a house that's been upgraded to be more airtight.
