This wall hung gas boiler is 96% efficient! This means only 4% of the heat from burning gas goes up the chimney! A 15 year old boiler may only be 65% efficient. This means you'll save 31% on your gas bill from this change alone! That's an easy decision!
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..

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.
