They heat water and then distribute the hot steam or the hot water to your home through pipes. Steam goes to the radiator and hot water flows to radiators or radiant heat systems. New boilers are extremely energy-efficient (even more so than a furnace). They get their fuel from natural gas, heating oil, electricity, or propane.
System boilers keep hot water in high-pressure, sealed cylinders. It can be distributed to multiple taps within your home at the same time, meaning there is a minimal drop in water pressure if multiple faucets are running at the same time.
Combination boilers are best for apartments or small homes. They heat water on demand, so you get hot water immediately and without delay, but the supply is limited since there is no tank holding the water.
Non-condensing boilers operate at higher temperatures and the heat gets vented outside, rather than being used to preheat the water in the boiler. The non-condensing boilers are less energy efficient as well.
Sealed combustion units are the better option, as they bring outside air into the burner and directs exhaust gases outside. Non-sealed combustion boilers bring the heated are in and then send it up the chimney, which wastes the energy used to heat the air.
Most U.S. homes are heated with either furnaces or boilers. Furnaces heat air and distribute the heated air through the house using ducts. Boilers heat water, and provide either hot water or steam for heating. Steam is distributed via pipes to steam radiators, and hot water can be distributed via baseboard radiators or radiant floor systems, or can heat air via a coil. Steam boilers operate at a higher temperature than hot water boilers, and are inherently less efficient; however, high-efficiency versions of all types of furnaces and boilers are currently available.

A central furnace or boiler's efficiency is measured by annual fuel utilization efficiency (AFUE). The Federal Trade Commission requires new furnaces or boilers to display their AFUE so consumers can compare heating efficiencies of various models. AFUE is a measure of how efficient the appliance is in converting the energy from fuel to heat over the course of a typical year.
Specifically, AFUE is the ratio of the furnace's or boiler's annual heat output compared to its total annual fossil fuel energy consumed. An AFUE of 90% means that 90% of the energy in the fuel becomes heat for the home and the other 10% escapes up the chimney and elsewhere. AFUE doesn't include the heat losses of the duct system or piping, which can be as much as 35% of the energy for output of the furnace when ducts are located in the attic, garage, or other partially conditioned or unconditioned space.
An all-electric furnace or boiler has no flue loss through a chimney. The AFUE rating for an all-electric furnace or boiler is between 95% and 100%. The lower values are for units installed outdoors because they have greater jacket heat loss. However, despite their high efficiency, the higher cost of electricity in most parts of the country makes all-electric furnaces or boilers an uneconomic choice. If you are interested in electric heating, consider installing a heat pump system.
Furnaces and boilers can be retrofitted to increase their efficiency. These upgrades improve the safety and efficiency of otherwise sound, older systems. The costs of retrofits should be carefully weighed against the cost of a new boiler or furnace, especially if replacement is likely within a few years or if you wish to switch to a different system for other reasons, such as adding air conditioning. If you choose to replace your heating system, you'll have the opportunity to install equipment that incorporates the most energy-efficient heating technologies available.
Other retrofitting options that can improve a system's energy efficiency include installing programmable thermostats, upgrading ductwork in forced-air systems, and adding zone control for hot-water systems, an option discussed in Heat Distribution Systems.
Although older fossil fuel furnace and boiler systems have efficiencies in the range of 56% to 70%, modern conventional heating systems can achieve efficiencies as high as 98.5%, converting nearly all the fuel to useful heat for your home. Energy efficiency upgrades and a new high-efficiency heating system can often cut your fuel bills and your furnace's pollution output in half. Upgrading your furnace or boiler from 56% to 90% efficiency in an average cold-climate house will save 1.5 tons of carbon dioxide emissions each year if you heat with natural gas, or 2.5 tons if you heat with oil.
If your furnace or boiler is old, worn out, inefficient, or significantly oversized, the simplest solution is to replace it with a modern high-efficiency model. Old coal burners that were switched over to oil or gas are prime candidates for replacement, as well as natural gas furnaces with pilot lights rather than electronic ignitions. Newer systems may be more efficient but are still likely to be oversized, and can often be modified to reduce their operating capacity.
When shopping for high-efficiency furnaces and boilers, look for the ENERGY STAR label. If you live in a cold climate, it usually makes sense to invest in the highest-efficiency system. In milder climates with lower annual heating costs, the extra investment required to go from 80% to 90% to 95% efficiency may be hard to justify. However, keep in mind that higher efficiency units will have lower emissions than units in the 80% range.
Specify a sealed combustion furnace or boiler, which will bring outside air directly into the burner and exhaust flue gases (combustion products) directly to the outside, without the need for a draft hood or damper. Furnaces and boilers that are not sealed-combustion units draw heated air into the unit for combustion and then send that air up the chimney, wasting the energy that was used to heat the air. Sealed-combustion units avoid that problem and also pose no risk of introducing dangerous combustion gases into your house. In furnaces that are not sealed-combustion units, back drafting of combustion gases can be a big problem.
Most older furnaces and boilers have natural draft chimneys. The combustion gases exit the home through the chimney using only their buoyancy combined with the chimney's height. Natural draft chimneys often have problems exhausting the combustion gases because of chimney blockage, wind or pressures inside the home that overcome the buoyancy of the gases.
Atmospheric, open-combustion furnaces and boilers, as well as fan-assisted furnaces and boilers, should be vented into masonry chimneys, metal double-wall chimneys, or another type of manufactured chimney. Masonry chimneys should have a fireclay, masonry liner or a retrofitted metal flue liner.
Many older chimneys have deteriorated liners or no liners at all and must be relined during furnace or boiler replacement. A chimney should be relined when any of the following changes are made to the combustion heating system:
Some fan-assisted, non-condensing furnaces and boilers, installed between 1987 and 1993, may be vented horizontally through high-temperature plastic vent pipe (not PVC pipe, which is safely used in condensing furnaces). This type of venting has been recalled and should be replaced by stainless steel vent pipe. If horizontal venting was used, an additional draft-inducing fan may be needed near the vent outlet to create adequate draft. Floor furnaces may have special venting problems because their vent connector exits the furnace close to the floor and may travel 10 to 30 feet before reaching a chimney. Check to see if this type of venting or the floor furnace itself needs replacement. If you smell gases, you have a venting problem that could affect your health. Contact your local utility or heating contractor to have this venting problem repaired immediately.
The average boiler replacement costs $8,300, though prices for boiler installation can range between $3,100 and $13,500, depending on the fuel and system type, the size of your home and the complexity of the installation. Standard boilers are often the most affordable, but you may find that options like high-efficiency boilers and combination boilers offer greater savings over time.
For example, high-efficiency boilers can significantly reduce home energy costs. With a combination boiler or system boiler, you can both heat your home and the potable water used in faucets, showers and appliances like washing machines and dishwashers.
HVAC technicians charge between $75 and $150 an hour for boiler installation. If the project is during their peak season or the work is especially challenging, anticipate paying on the high end of that range.
Your boiler replacement cost depends on the type of system you purchase. Standard (or conventional) boilers are more affordable than system and combination boilers, and high-efficiency boilers are the most expensive type of all.
Once popular, oil boilers are now less common than fuel other types. Oil itself has grown more expensive, and the actual units cost from $4,700 to $7,900, making them one of the more expensive options. Oil boilers also require more maintenance over their lifetime, which adds to their overall cost.
One of the largest factors affecting the cost of a boiler installation is the type of boiler itself. High-efficiency boilers can cost five times as much as a standard boiler. System and combi boilers, which also heat your potable water, are often more expensive than standard boilers as well. 041b061a72
