Sealed System Boilers: An Introduction With FAQs

Posted on: 12 April 2019

If you have a rather small industrial operation and your need for steam is not that great, a sealed system boiler may be the right kind of boiler for you. These smaller units are typically installed in residential properties, but they work well in small operations just the same whether you are looking for a small amount of steam provision, heat production, or hot water. Sealed system boilers have pressurized hot water kept in a cylinder, so when there is a demand for steam at a tap, it is ready. Take a look at some of the things you likely want to know about sealed system boiler installation

How much is a sealed system boiler?

Sealed system boilers are considered to be the most affordable type of boiler system you can find, which is another reason why it is logical for a small-scale operation. You can expect the average cost of sealed boiler systems to fall in at around $1,500, which is pretty affordable compared to something like a standard boiler that would run you as much as $3,500. The installation costs tend to also be conservative because these units are not so large and difficult to get into place. 

How does a sealed system boiler differ from a standard boiler?

One of the biggest differences between a sealed system boiler and a standard boiler is the size, but these units also differ in a couple of other ways. For instance, a standard boiler does not take as long to heat up water once the tank is filled with fresh water because it is continuously being refilled as the water is used. Sealed systems usually have a brief delay, so heated water is not sent out instantly as it would be with a standard boiler unit. 

Do sealed system boilers last as long as standard boiler units?

In most cases, you will get about as many years out of one as you would the other as long as the unit is properly maintained and serviced as needed. Of course, this will also depend on how much you use the smaller boiler, the quality of the water being sent through the system, and things of that nature. In general terms, most boilers do provide about 15 good years of service, so you should expect at least that long out of a unit that is properly taken care of on a regular basis.

CNC And Water Jet Fabrication: An Introduction

The first time I watched a water jet machine in operation, I was awestruck by the speed and precision with which it cut through the metal. That's when I knew I had to understand what made them work. I spent years researching and learning the basics of how CNC programming drove the machines, and the language that made the programming function. In my research, I learned that, while CNC was the most efficient means, it wasn't widely known. That's why I created this site. I hope to show others the value in CNC programming so that they can determine if it is right for their operation.
