steam boilers guide : The best natural gas steam boilers for sale in 2022

The average cost for a Natural gas steam boiler is about $3,500. A higher end steam boiler installation could cost up to $8,000. They rely on simple mechanics, which make them highly reliable to work with. Still, they are not particularly efficient or quiet compared to hot water boilers on the market today.

Natural gas steam boilers are used to produce steam for industrial processes and heating. Steam is created by heating water in a boiler. The heat can come from a variety of sources, including natural gas and oil. Natural gas has become the preferred fuel source for steam boilers because it’s much less expensive than oil or propane, which makes it more economical for commercial and industrial users who rely on steam to keep their plants running smoothly.

What is natural gas steam boiler?

Natural gas steam boilers are a type of water-tube boiler that uses natural gas as fuel. They are also known as “combined cycle” boilers because they use two heat exchangers to convert the energy from the burning gas into usable heat, much like in an electric power plant.

The process begins when natural gas is ignited in a firebox, which is located at one end of the furnace. The flame travels through pipes along its length to reach all corners of the furnace’s interior and burn all available fuel before exiting through exhaust pipes at another end of the furnace, where it releases its waste gases into air outside.

As this occurs inside your home or office building, water circulates through hundreds or thousands of tubes running throughout your boiler’s core to absorb heat produced by combustion. This heated water then travels back out through return lines toward an external condenser unit where it turns into steam that powers turbines that produce electricity for use elsewhere within your facility (if you have one).

How do natural gas boilers work?

Natural gas boilers are the most popular choice for home heating. They are also used to generate electricity, and have been in use since the mid-1800s. In order to understand how these boilers work, you must first understand how combustion works.

Natural gas steam boilers are fueled by natural gas. The fuel burns in a furnace that heats up water from the boiler’s tank or vessel. This heat is transferred through metal pipes (called flues) which carry it around your house or building so that it can warm up your rooms and appliances as needed. When enough heat has been produced by burning natural gas, part of it turns into steam and rises into vents known as chimneys or stacks—these vents allow excess gases from combustion to escape so they don’t build up inside your home’s ductwork system (which could lead to an explosion).

How long do natural gas steam boilers last?

The average lifespan of a steam boiler is 15-20 years. This lifespan depends on how well it is maintained and operated. If you do not properly maintain your unit and rely heavily on it, then you may be looking at replacing it in as little as 10 years.

This is because the boiler will eventually become too inefficient to work properly, and it will stop producing steam.

How much does it cost to replace a natural gas steam boiler?

The cost of a natural gas steam boiler depends on several factors, including size and efficiency. It can range from $10,000 to $50,000 or more.

The price will depend on how much energy you need and how many features the system has. For example, a low-end model will typically have fewer features (such as sensors) than an expensive one would. Also keep in mind that if your current natural gas steam boiler isn’t working well anymore, replacing it might not be the only option—you might just need some repairs instead!

How efficient are natural gas steam boilers?

natural gas steam boiler efficiency

Natural gas steam boilers are considered to be very efficient. The typical efficiency of a natural gas steam boiler is about 90%, meaning that for every 100 BTUs of heat energy put into the boiler, 90 BTUs of useful hot water or steam will be produced.

The efficiency of a particular natural gas steam boiler can be calculated by multiplying its therms per hour output by 0.90 (0.9). For example, if your natural gas burner produces 10 thousand BTU/hr and you use it for 24 hours in one day, then the total heat captured would be 240 thousand BTU which would generate 240 thousand divided by 24 hours = 10 thousand gallons per hour (or gph).

This means that for every 1000 gallons per hour output there are 990 gallons of useful hot water or steam produced from your system! So if you want a 100% efficient system instead then divide 1000 by 990 = 0.995 (which is still quite good!)

How do I choose the right nutural gas steam boiler?

  • Choose a boiler that is right for your home.
  • Consider your budget.
  • Think about the size of your home and family.
  • Consider the type of heating system you have now, as well as how much space you have in which to install it. If you’re replacing an existing boiler, then this won’t be an issue—but if you need to purchase all new equipment, then finding one that fits not only your needs but also your available space can be difficult. You may also want to consider what fuel type is most efficient for heating water in order to save money on utility bills over time (natural gas vs propane).


The best way to decide which natural gas steam boiler is right for your home is to shop around. There are many different models on the market, but they all offer similar benefits when it comes down to heating water and providing hot water for showers and baths. We recommend looking at reviews online before making any decisions so you can find out what other people think of their own experience with purchasing a new unit!
