Modern, high-efficiency boilers have been designed to trap any escaping heat and direct it back into the boiler system itself. Why is a High-Efficiency Rating Important? Low-efficiency boilers tend to experience high levels of heat loss, requiring more fuel to do the work of an efficient system. Most boilers that are over 10 years old have efficiency ratings of just 50 to 70 percent. That means between 30 and 50 percent of the fuel used to heat your house is wasted.
High efficiency boilers generally have efficiency ratings over 90%, making them Energy Star approved. These boilers are often modulating and condensing boilers. The modulation feature allows them to operate at different BTU levels depending upon the amount of heat that is required at a given time (as opposed to a traditional boiler that fires at 100% even if only a small amount of heat is required).
Boilers have an average cost between $2,500 and $4,000 for mid-efficiency units, and between $5,000 and $10,000 for high-efficiency units, including installation costs. Furnaces have an average cost between $2,000 and $3,500 including labor costs.
Standard (non-condensing) boilers vs. condensing boilers: Boilers with AFUE efficiency between about 80% and 84% are termed standard efficiency. If the units have 85% to 90% efficiency, some brands call them high-efficiency boilers. Most standard boilers have cast iron heat exchangers.
The U.S. Department of Energy estimates that replacing an older boiler system with a new, high-efficiency one may cut your fuel bills in half. Boiler Maintenance Regardless of the differences between various residential boiler systems, proper maintenance is needed to keep your system running efficiently.

#1. Cast iron boiler vs. high efficiency stainless steel. We want to replace our 38 year old gas-fired boiler. We live in the Boston area in a single-family split-level home built in 1974. Our existing boiler has an input of 210,000 Btu/hr and an output of 168,000 Btu/hr, which makes it 80% efficient.
The diverse steam boiler selection at Grainger includes high-efficiency wall-mounted condensing boilers, cast iron compact gas-fired boilers and direct-spark boilers with Energy Star ratings. Also find low profile gas-fired boilers with built-in draft diverters and pressure switches to detect blocked vents.
All residential gas fired boilers burn gas. The higher the boiler's efficiency is, the less gas it burns. Imagine you have two stoves that are especially designed for heating a home of 1,500 square feet. One of them has an 85% efficiency rating, while the second one has a 95% rating.
Environmental Protection Agency together with Department of Energy usually awards an Energy Star label to those boilers, which have an AFUE of 85 % and even more. Today there are high efficiency boilers residential that claim an AFUE of 97%.
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 gas, or 2.5 tons if you heat with oil.
The CHS Series are condensing boilers, so achieve an efficiency of boilers are made in a wide range: 85, 110, 154, 175, 200, 250, 340 and 399MBH. The CHS Series is low-NOx for regions with strict emissions standards. It uses a fire tube design like the other condensing series in this list.
Burnham Boiler Reviews | Consumer Ratings. by | Boiler Reviews | 1 comment. Burnham Boiler Reviews - Burnham offers boilers with efficiency ranges from 81% AFUE to 95% AFUE. They are the only HVAC manufacturer High Performance HVAC has found that publishes the certifications of efficiency certificates from GAMA (now AHRI) .
At this time of increasing energy costs and emphasis on maximum effieciency why doesn't anyone manufacture a gas fired steam boiler higher than 82% efficiency? There are many hot water boilers at 90+% efficiency - this shouldn't be rocket science.
Burnham. It is available in multiple heating capacities that can be configured for water or steam, with or without a tankless hot water heating coil. Burnham's MPO boiler, with an AFUE of 87%, is one of the most efficient and reliable boilers in the industry.
High-efficiency propane boilers provide energy, cost, and carbon savings in both new and existing homes. As an illustration of these savings, the table below compares a standard efficiency oil boiler (84 AFUE) with an Energy Star "Most Efficient" propane boiler (96 AFUE) in a typical new 2,400-square-foot home.
ENERGY STAR certified gas boilers have annual fuel utilization efficiency (AFUE) ratings of 90%, approximately 8% more efficient than the federal standard. ENERGY STAR certified oil boilers have annual fuel utilization efficiency (AFUE) ratings of 87%, approximately 3% more efficient than the federal standard.
They see an 80% efficiency rating on a steam boiler and automaticallly assume that the steam boiler is less efficient than a 90% efficiency furnace. Steam must be old and inefficient heat and we need to tear it out and put in a new 90% efficiency furnace..this is what they are thinking.
Steam heat from the efficiency experts The GWM-IE boiler offers an efficiency of up to 95% AFUE, meaning it converts up to 95% of its fuel into useable heat. Fuel flexibility lets you use either natural or LP gas as a heat source.
Oil-fired boilers are a great solution for residential applications. Available for both water and steam systems, high efficiency residential oil boilers from Weil-McLain are rugged, reliable, and produce more heat per BTU than a standard gas-fueled system.
A residential boiler's efficiency rating is typically measured by its AFUE (Annual Fuel Utilization Efficiency). Commercial boiler efficiency is often measured by combustion efficiency rather than AFUE. The "fleet efficiency" of a particular brand is the average efficiency of all of the models sold under that brand name.
