As you shop for boilers and read their specifications, youll see three materials used in heat exchangers: cast iron, aluminum and stainless steel. The heat exchanger is the part that transfers heat from the combustion gases into the water that is being circulated by the boiler, so it is a crucial part of the design.
3III Equipment Options. Sectional boilers can be constructed from cast aluminum or cast iron. Any number of individual sections can be connected together to provide any boiler capacity up to a maximum of approx 150 horsepower. IV Resources. 1. Equipment Manufacturer Database. 2.
Jun 07, 2016 Central Heating Radiators: Aluminum Vs Cast Iron. In the case of cast iron radiators versus aluminum radiators, there is an extremely curious debate regarding which is more efficient for consumers. The newest piece in radiator technology, bi-metal aluminum radiators, has caused quite the stir as another efficient means of heating.
The better value may be the cast-iron boiler. Pay particular attention to performing, or having performed, a heat-loss calculation. You can then size the boiler based upon that calculation. A conventional boiler may be less expensive as well, depending upon the size required and if your chimney needs re-lining.
Cast iron was predominant in Europe until the early 1980s when copper boilers began to take over the European market. In the U.S., cast iron boilers have been in use for many decades. In recent years, both aluminum and stainless steel heat exchangers have been successfully used as main components of high efficiency condensing boilers. 4.2 ALUMINUM

Dec 01, 2004 Water chemistry w/Aluminum boilers + Iron radiators. A development in the boiler market has seen the use of Aluminum (AI) heat exchangers in boilers. Aluminum is in greater use for several reasons - the most important being lower cost, lower weight and greater heat exchange when compared to other metals.
As an example, a finned tube configuration of 2 (nominal, 2.375 actual) pipe with a high welded helical solid fin of 12 gauge thickness with 6 fins per inch has an outside surface area of 8.23 sq. ft. per linear foot; whereas the same bare pipe has an outside surface area of only .62 sq. ft. per linear foot.
I have a 1950s house with the cast iron radiators with a monoflo loop system feeding them. I am replacing the boiler and was wondering if there is any reasons not to re-use the cast radiators. Which is a better choice with todays technology. Is there a formula to how much fin is needed to replace one cast iron?
Dec 15, 2017 Steel flat panel radiators typically have more thermal mass per rated BTU than cast iron baseboard, aluminium convecting rads usually less. For guesstimating how much c.i. baseboard it takes to deliver a rooms design heat load at 140F AWT assume ~300-325 BTU/hr per running foot.
High Temp Heat Emitters. Condensing boilers achieve higher efficiency by absorbing the latent heat in the flue gas. The requires the heating system to operate below the condensation point which is roughly 130F. Copper fin tube and cast iron radiators are generally thought of as high temperature emitters.
So my question is whether I should replace the slant-fin copper/aluminum baseboard with cast-iron baseboard as part of the kitchen/boiler work? The base-ray does not have as high a heat output rating as the multi-pak 80 (620 btuH vs. 840 btuH), but would it be a better choice, given the fact that the rest of the house (in a separate zone) uses ...

Cast iron is an excellent conductor of heat and therefore works far better in larger spaces with taller ceilings. Although they do tend to take quite a bit longer to heat up due to the density of cast iron as a material, once at temperature they retain that heat much longer than any other radiator type. Space vs heat output of Cast Iron Radiators
Trying to learn the pros and cons of oil vs gas, and steam vs hydronics when it comes to heating with old radiators. @STEVEusaPA My cast iron boiler cracked this winter and when I discovered it this spring I had a Pensotti boiler with Rielo burner put in. I would love to have an octopus, but I like the look and sounds of steam radiators.

In the world of high-efficiency condensing boilers, a major point of discussion is the . choice of stainless steel or aluminum heat exchangers. Though both materials boast some advantages, HTP has opted to use only high-quality stainless steel for the heat exchangers in our popular Munchkin, ModCon and Elite boilers. Heres why.

The maintenance for boilers is entirely different. High efficiency boilers and oil boilers (like a warm air furnace) usually require annual service, but a cast iron gas boiler can run for years with minimal maintenance. When it comes to boiler vs. furnace, which one makes more sense for you depends on your needs and your budget.
Jan 05, 2017 Cast iron responds to very low supply temperatures providing constant heat at low outputs. It benefits the condensing boiler by allowing it to run at its lowest firing rate, giving homeowners the lowest possible fuel bills. Condensing boilers rely on low return temperatures to keep its efficiencies in the 95% range.
