But over the years I have replaced more failed copper boilers then any other type of boiler. They are a "low mass" boiler and very sensitive to water flow rates and operating temperature. I have installed many of them in my day. I now refuse to use them. Rated the same as cast iron boilers, about 82%. High efficiency- Well, these are the
Cast-Iron Boilers, in AECinfo.com, your source of North American building product and supplier information, including brochures, specs and CAD details, since 1995.
Retrofit applications replacing cast iron boilers are an ideal place for a high mass boiler. Gone are the worries about plugged exchangers, water treatments, and endless flushing. Let's not forget high mass boilers were first then the low mass boilers came on the market as higher efficiency options.
The cast iron heat exchanger is the heart of these boilers. It is manufactured in Zanesville, Ohio and is designed for years of reliable service. Each heat exchanger is water and pressure tested prior to assembly. The boilers themselves are built in Lancaster, PA. Every component used in the IQ family of boilers is subject to strict standards of
If you have old fashioned high volume cast iron boilers it has quite a bit of thermal mass in both the water and the iron. The specific heat of cast iron is about 0.11 BTU/lb-degree-F, so it takes ~9.1 lbs of cast radiator to add up to the thermal mass of a pound of water (or ~76 lbs of cast iron to be equivalent to a gallon of water), but if
Cast iron construction, ease of assembly, two venting options and stringent testing methods make the V9A Series boiler by Burnham Commercial your commercial heating solution. American-Made Cast Iron Construction Burnham Commercial's unique cast iron formula has an extremely high silicon content, making it stronger and more flexible.
The Sentinel boiler combines the reliability of natural draft and cast-iron construction with the high efficiency perform-ance provided by the Slant/Fin S-Series heat exchanger.

Traditional cast iron boiler CONCEPT Cast iron holds a special place among the materials used for making boilers. In fact, using cast iron, quality boilers can be designed that can produce low pressure steam (100 kPa) or hot water at high or low pressure (up to 620 kPa maximum). Cast iron boilers are heavier
Cast-iron boilers are often found in residential applications and small commercial installations. These boilers are compact and function exclusively in low-pressure steam or hot-water applications. The physical size of a cast-iron steam boiler can be quite large, with the sections visible, since it has no casing. Cast-iron is basically steel. It has higher levels of

KN Series high efficiency cast iron boilers are built for the long haul in Boyertown, PA. They cycle less, offer better thermal mass and have walls 5X thicker than stainless steel heat exchangers.
The old cast boilers and the modern day standard efficiency boilers are a good deal simpler. This complexity occasionally vexes some contractors. However, if you use a high-quality boiler (like our Buderus GB142) and trained installation and service personnel, the complexity isn't really a hurdle at all.
The majority of the hydronic boilers we install today are low-mass, modulating condensing boilers. Sure, we still install a few atmospheric cast iron boilers on occasion, when budget, venting or condensate drainage issues dictate this choice. But eight out of ten hot water boilers we install are high-efficiency condensing boilers.
From homes equipped with high mass cast iron radiators, to homes with multi-zone high temperature fin tube radiators, and new installations with high DHW requirements - the Vitocrossal 300, CU3A is the best choice on the market today. The benefits at a glance. Compact, floor-standing gas condensing boiler from 19-199 MBH.
Proper near boiler piping also plays a huge part in boiler and system efficiency. Boiler efficiency is not a huge part of fuel savings as the efficiency of the boiler changes by the minute when the boiler is running. As vent temps go up efficiency goes down. Mod/cons take a bigger hit on efficiency than cast iron boilers do.

Whether you need the traditional reliability of American made Cast Iron oil or gas boilers, or the latest high efficiency boiler systems, we have the experience and support necessary to help you make educated choices.
If you use a heat-purging boiler control such as the Intellicon 3250 or it's cousin the Beckett Heat manager, the savings are similar to using "outdoor reset" type controls on a high-mass cast iron boiler, in part because the average temp of the water is lower, and the boiler is "parked" at a lower temp during standby, for lower standby losses.
New Yorker Boiler Company, manufacturer of reliable residential hydronic-heating products, offers a complete line of cast iron and steel boilers, as well as an indirect water heater. With a product line that offers both gas-fired water and steam and oil-fired water or steam boilers, New Yorker Boiler now offers a new ENERGY STAR certified, high
Condensing boilers are rated at a higher efficiency than standard cast iron atmospheric boilers. The reason for the higher efficiency is the heat exchangers. Condensing boilers and furnaces use two heat exchangers, so they make better use of the combustion process and making use of the heat produced.
The TRIO is constructed of GG20 cast iron for greater durability and thermal shock protection. The TRIO is a low mass boiler with steel push nipples. This manufacturer process is a better engineering technique than boiler sections which are put together with gasket materials.

Practical Strategies For Condensing Boiler Retrofits. cast iron or copper, which are unable to withstand the corrosive condensate produced with condensing. High-mass boilers can be piped in a variable-flow primary arrangement to maximize overall system efficiency from both a boiler-efficiency and pumping-energy standpoint.
2017-6-16 · Condensing boilers can provide significant energy savings due to operating efficiencies as high as 98% as compared to a peak efficiency of 80% for a conventional boiler. However, specifying a condensing boiler does not guarantee achieving anticipated savings; careful attention must be paid to the heating water system as a whole.
Chapter 3 - Hydronic Heat Sources If a cast-iron boiler is significantly oversized and experiences long off-times between firing cycles, much of the heat stored in the boiler's thermal mass can be carried up the flue by air currents passing through the combustion chamber. Answer.
Many cast iron boilers will get too much condensation and soot up, especially if they're high mass. Will take too long to come up to temp to service an Indirect hot water tank. Better option is warm start, let the boiler drop to 120 degrees. This works better on well insulated 3 pass boilers, since they're slower to cool down.
A cast iron boiler can weigh upwards of 500 pounds. Removing a cast iron boiler from a basement is not an easy task. They are very heavy and oddly shaped. In addition to the weight, they are very dirty. Jacobs Property Solutions has successfully removed over 250 cast iron boilers and old steam pipes from homes throughout southern New England.
