A furnace or boiler's efficiency rating, or AFUE (Annual Fuel Utilization Efficiency), tells you how efficient furnaces or boilers use fuel (gas or oil). Mid-efficiency furnaces or boilers, also known as non-condensing or induced draft units, offer efficiencies from 78% to about 84%.
This ultra high efficiency dual purpose boiler has an AFUE rating of 95% which provides 140k BTUs for space heating and comes with an optional domestic hot water capability that can provide 3.2 gal/minute at a 77° temperature rise. This product provides home owners with one appliance that saves money on operating expenses, reduces overall installation costs and takes up less space than
A condensing boiler, on the other hand, recovers the heat from the water vapor and puts it back into the boiler. This allows a condensing boiler to use less fuel to produce the same amount of heat. Same comfort, less fuel, lower bills. Consider the Annual Fuel Utilization Efficiency (AFUE) rating of a boiler, which is a measure of its efficiency.
indirect-fired water heaters provide up to twice the peak flow of a tankless coil, 50% more than a comparable sized direct-fired gas water heater, and three times as much as an electric unit. Annual estimated savings for every $100 of fuel costs by increasing your heating equipment efficiency. Source:"Furnaces and Boilers."
The higher your new furnace's AFUE rating the better your energy efficiency will be. The minimum AFUE rating you'll find on the top brands will be a 78% rating. A mid-efficiency furnace will have an 80% to 85% AFUE rating, while a high energy efficient unit can get up to 90% to 97% AFUE rating.
Only condensing furnaces are able to achieve the highest AFUE ratings of over 90 percent, with some reaching over 98 percent. How a High-Efficiency Condensing Furnace Differs While the condensing furnace is different in its design and repair needs , it does have some similarities to a conventional furnace.
It is an energy efficient boiler with 95% AFUE that can not only heat your home, but also provide domestic hot water all from one boiler. Available in 3 sizes with heating and domestic hot water inputs up to 180 MBH and a 10:1 turndown, the Phantom Combi is one of our most versatile condensing boilers.
Trane 95 and 90 gas furnaces deliver at least 90% efficiency, far exceeding the government minimum standard of 80 AFUE for new furnaces. If you have a furnace that is at least 10 years old, it probably has an AFUE somewhere between 60 and 70 - meaning up to 40 cents of every dollar you pay for fuel is wasted.

Unlike a furnace that heats and distributes air, a boiler heats and distributes water, sending it through pipes as steam to radiators, or as hot water to baseboard heaters, radiant floor systems, snowmelt systems, pool heaters or to a fan coil unit that then heats air. Boilers are typically fueled by gas or oil. Typical costs: Installing a standard boiler (80%-85% annual fuel utilization
The annual fuel utilization efficiency (AFUE; pronounced 'A'-'Few' or 'A'-'F'-'U'-'E') is a thermal efficiency measure of space-heating furnaces and boilers. The AFUE differs from the true 'thermal efficiency' in that it is not a steady-state, peak measure of conversion efficiency, but instead attempts to represent the actual, season-long, average efficiency of that piece of equipment
As a combi boiler, Heatslave II boilers provide central heating and hot water on demand, with an impressive flow rate of 15 litres per minute. The range includes oil boilers with output ratings of 18 kW, 25 kW and 32 kW, making it easier to find a suitably powerful boiler for your property.
Introducing the Accel CS Condensing Boiler. To overcome the inefficiencies of these poorly designed combi boilers, Energy Kinetics created the Accel CS Condensing Boiler, the most efficient and longest lasting condensing boiler on the market.Not only is the Accel CS constructed with superior materials, it was designed by Energy Kinetics' engineers who possess a long history of engineering
Forced Hot Water Heating. AFUE is a rating that reflects how efficiently heating system converts fuel to energy. CONDENSING BOILER One of our customers asked us to replace their old oil boiler with a natural gas fired forced hot water system. We looked at their basement and saw that it was being used as a recreation room, as well as the
Specifically, AFUE is the ratio of annual heat output of the furnace or boiler compared to the total annual fossil fuel energy consumed by a furnace or boiler. 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 flue and elsewhere.
Test Procedure. DOE has published a Federal Register notice of petition for rulemaking and a request for comment pertaining to test procedures for consumer warm air furnaces 83 FR 56746 (November 14, 2018).. DOE published a final rule pertaining to test procedures for residential furnaces. 81 FR 2628 (January 15, 2016).. The residential furnace and boiler test procedure docket EERE-2018-BT-PET
Another way to determine a boiler's efficiency is to look at whether it's a condensing vs non-condensing boiler: Non-condensing boilers are 80-88% AFUE-rated. During a heating cycle, they allow heat from water vapor to vent outdoors, wasted. Condensing boilers are 90%+ AFUE-rated. During a heating cycle, they capture the heat from water
The AFUE, or annual fuel utilization efficiency, of your heating equipment is a measure of the amount of energy consumed by the boiler or furnace compared to the amount of heat that it delivers to the system. So, a heater with an AFUE of 90 percent will lose 10 percent of its heat up the chimney.
The AFUE rating, or Annual Fuel Utilization, measures how efficient your furnace is. You can check your unit's rating by looking at the yellow Energyguide sheet on the side of your unit. If your furnace's AFUE is above 90, you most likely have a condensing furnace. If your furnace's AFUE rating is below 90, you most likely have a
The annual fuel utilization efficiency (AFUE) rating is used to measure a furnace's efficiency. Furnaces today have AFUE ratings of 78 to 96 percent. The Federal Trade Commission (FTC) requires manufacturers to indicate the AFUE on the label of furnaces. Most furnaces for residential use have an AFUE rating of 80, 90 or 95 percent.
The minimum AFUE for gas-fired hot water (hydronic) boilers is 82% The minimum AFUE for oil-fired hot water boilers is 84%; In Canada, National Resources Canada (NRC) as of 2009 specifies that gas furnaces manufactured after 31 December 23 2009 must have an AFUE of 90%. Kudos to the Canadian NRC. Typical AFUE Ratings for Heater Types & Various
Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.This condensed vapour leaves the system in liquid form, via a drain.
However, specifying a condensing boiler does not guarantee achieving anticipated savings; careful attention must be paid to the heating water system as a whole. The first principal is that low boiler entering water temperatures (EWT) are required to realize the advertised efficiency and AFUE performance of condensing boilers.
The minimum allowed AFUE rating for a non-condensing fossil-fueled, warm-air furnace is 78%: the minimum rating for a fossil-fueled boiler is 80%: and the minimum rating for a gas-fueled steam boiler is 75%. The AFUE rating for a condensing unit can be much higher (by more than 10 percentage points) than a non-condensing furnace.
Chapter 2 Boiler 101: typical NYC residential heating system One and two family homes often use forced-hot-air heating systems, which include a burner, heat exchanger and blower(s). In these types of systems, hot air is forced through ducts to every room in the house, where it blows out of vents that are usually located at floor level.
