Customer Questions & Answers

What is the maximum steam pressure of this boiler?

What is the maximum steam pressure of this boiler?
Asked by: mikey343
First and foremost this is a residential LOW PRESSURE boiler. It is not designed nor should it be used for commercial live steam applications such as dry cleaning. Residential steam boilers are usually set to shut off when the pressuretrol senses that the pressure has reached 1/2 a pound of pressure. The pressure relief valve utilized in this boiler is set to go off at 15 PSI. Some qualified trades people may turn the pressure regulator up a couple pounds when servicing and decontaminating the system but in normal operation I would never go above a one pound. A residential steam system should not need anything higher than a half a pound. If it is run any higher the vents on the radiators will fail.

Can i Use it for dry cleaning equipment ?

Can i Use it for dry cleaning equipment ?
Asked by: Allen
No I would not recommend it. Cast iron boilers are designed to use the same water over and over again. Thus the water becomes oxygen deficient and does not rot out the iron. Steam boilers designed to create process steam that will not be returning to the boiler as condensate are constructed differently. A Sussman Co from NY makes the types of boiler you are looking for.

How many square feet will this unit heat or how do you size a boiler for a house?

Asked by: Charlie
That is a great question. Because your question is tide to a steam boiler, I am going to answer it assuming you have steam. First, and this is with all heating systems, you need to size it based on a heat loss calculation. Basically this is a mathematical estimate of how much heat the structure will lose on the coldest hour of the coldest day of the year. Obviously the same structure if located in Alaska is going to lose more heat than if it is in Florida; due to the temperature outside. There are many programs on line that are available to do this. You enter room dimensions, location, windows, construction specifics, etc, and it will calculate how much heat you lose, thus how much you need to put back in to keep the house warm. This is true of all heating systems. However with steam you have an added variable. You not only need enough capacity in BTU's you also need enough volume of steam to fill the entire system. The unit is called "square footage of steam" Sometimes I find that if I do a heat loss I will come up with a figure for the structure but then when I add up the capacity of the radiators and pipe, I need to go large so there is enough volume of steam to reach the furthest radiators. Steam boilers have gotten smaller over the years in an effort to reduce there operating costs. So it is vert important that you chose one with both enough heating capacity, in BTU's and enough volume in Square Footage of Steam to fill the steam. I typically ask people did the boiler you are replacing adequately heat all the radiators? If it did I will start by looking at the rating plate of the current boiler. It will indicate the rating in both BTU's and Square Footage of Steam. I then use that as a base line for deciding on a replacement. Please also keep in mind when replacing a steam boiler the piping with in 5' of the boiler is part of the boiler. This is called the near boiler piping. It is critical that this piping be done in a specific way for that boiler. If it is not the boiler will not operate correctly. Meaning you can't just cut the pipes off the old boiler, slide in a new one and assume it will work. It just does not work that way. The majority of steam problems are due to incorrect near boiler piping. So look at the installation specifics, in the manual, before installing. They often appear counter intuitive but that is due to the nature of steam. If you have questions ask. Chris 978 651 3301
