Keep in mind that they are also typically designed for a 40°F water side temperature drop which brings your return water back at 120°F during design conditions, low
boiler heating water system as a whole. Condensing boilers require entering water temperature (EWT) in the 100˚F (55˚C) range to actually condense water out of the exiting flue gas. The onset of condensing is with an EWT of about 130˚F (54˚C), but maximum
Low return temperatures provide a means to lower the stack temperature. Typically condensing boilers run a stack temp about 30-40 degrees warmer than the return temp. Exhausting higher temperatures is of course a waste of heat up the chimney and wasted dollars.
It is worth noting that this reset curve is specific to boilers that can tolerate condensing flue gas caused by sustaining return-water temperature below 140 F. In general, do not apply this curve to a non-condensing boiler, as the flue and boiler will need to be replaced prematurely because of corrosion.
Our extensive selection of heating products includes two super-efficient condensing gas boilers, the Burnham Alpine™ and K2™ boilers. How do condensing boilers differ from conventional boilers? The answer is "efficiency". The most efficient boilers keep heat in the house rather than letting it escape through the chimney or vent pipe. A condensing boiler recovers some of the wasted heat and is on average, 25% more efficient than a conventional boiler.
Apr 11, 2012 · Getting the Most Out of Your Commercial Condensing Boiler. Usually, these are boilers whose construction allows them to operate with lower water temperatures than traditional boilers. This allows them to, in theory, extract more of the useful energy from the fuel source (usually natural gas or propane) than the traditional boiler would

Even the Thermostream series boilers (315&515) call for a minimum BOILER temperature for sustained operation. IIRC the operating temp minimum is 131* or around there. You are correct that they will tolerate low (<100*) return temps.
• Condensing Boilers • How does a condensing boiler work ? • Very similar to a hydronic boiler except it is designed capture even more heat from the flue gases. The flue gases give up their latent heat, forming condensate. • Flue Gas temperature of Condensing boiler is 120-140 degrees • Flue Gas temperature of standard hydronic boiler is 250 to 400 degrees
IBA is leading manufacturer for various condensing or extraction steam turbine models and sizes are available. Call us today at 855.465.1882. The gas exits the turbine as a saturated vapor (or liquid-vapor mix depending on application) at a lower temperature and pressure than it entered with and is sent to the condenser to be cooled.
Steam and high temperature hot water boilers 4 energy consumption Steam and high temperature hot water (HTHW) boilers are commonly used in industrial sectors and in some applications in public and commercial organisations. They are found in circumstances where there is a continual demand for steam or hot water, in a wide
Apr 11, 2012 · The vapor in the flue gas only starts to condense at about 130° F return water temperature. You get very little increase in efficiency beyond non-condensing operation at this temperature. Slightly above a 70° F return water temperature is when you hit the 98%-99% efficiency numbers you often see advertised.
MHI's One Atmosphere Boiler superheated steam boiler features patented InstaSteamâ„¢ technology, allowing for rapid startup times, unparalleled efficiencies and up to 1300°C temperatures. BoilerFreeâ„¢ technology allows most OAB units to be installed without the need for traditional boiler certifications.
however, payback ranged between 4 and 7 years. When compared to high-efficiency boilers, condensing boilers were found to be life-cycle cost-effective even when only 3%-5% more efficient. LOW RETURN WATER TEMPERATURES ENSURE CONDENSING BOILER EFFICIENCY To operate in condensing mode, a return water temperature (RWT) below 130°F is required.
The Concept of Condensing Boilers ENERGY SAVINGS AND Figure 7: Categories of gas condensing boilers BAXI CONDENSING TECHNOLOGY For BAXI high-efficiency boilers, condensing If used in low temperature heating systems, the boilers can achieve fuel consumption savings of 35% and more, when compared to
Keep in mind that they are also typically designed for a 40°F water side temperature drop which brings your return water back at 120°F during design conditions, low
it is formed by cooling a gas of extremely low density, about one-hundred-thousand the density of normal air, to super low temperature.
The water temperature determines the capacity and how fast the heat comes from the baseboard heaters. In properly designed systems, water temperature should be between 140 and 180F. Commercial boilers and some newer residential units, have a control that varies the water temperature (called a Boiler Reset) with the outdoor temperature. The lower the water temperature, the more efficient the boiler

A condensing boiler is a modern, highly efficient boiler. It makes the fuel you're burning to heat your home go further. To find out which boiler is best suited to your needs, it may help to understand more about condensing boilers and boiler efficiency.
Condensing boilers achieve high efficiency by capturing the additional heat released from condensing flue gas (up to 12 or 13 percent of the original energy content of the gas). For flue gas to condense, return water must be below about 140 F. For this reason, condensing boilers are most suitable for low-temperature systems, such as radiant floor heating, swimming pool or spa, dedicated water heating,
