In any home, it’s necessary to have a boiler because it’s the primary source of heat, especially during the winter months. It’s not just homes because even commercial buildings need boilers. Luckily, some boilers are specifically designed for commercial use.

Commercial boilers are larger and sturdier, and they can burn a variety of fuels, but they usually burn fuel oil. The good thing about commercial boilers is that they are more efficient, though they are a lot more expensive. Most people are unwilling to spend so much for a boiler for their homes, but if you decide to buy a commercial boiler, it will pay for itself in a few years.

It’s essential to get yourself acquainted with the different types of commercial boilers, which we’ll discuss in this article. Read on below to get started.

Commercial Electric Boilers

This is the most basic type of commercial boiler. It’s perfect for smaller establishments such as restaurants, medical offices, small business offices, and other buildings with low to moderate heating needs. The boiler will convert the electric power from a wall outlet into heat. It takes in the electric power and transforms it into heat energy. It breaks the power down into smaller amounts and sends it to the burner or heating unit.

Commercial electric boilers are the least expensive, and they are very easy to install. Commercial electric boilers are not very expensive, so you won’t have difficulty affording them.

Condensing Boilers

Condensing boilers are a lot more efficient than steam boilers. They are much more expensive than steam boilers, but they can save you a ton of money in the long run because they only use a small percentage of fuel. Condensing boilers use a lot less gas, oil, or other fuels. These boilers are highly energy-efficient compared to older types of boilers.

Condensing boilers are also known as condensing units or heat recovery units. They do two things: heat and cool. They heat the water, distributed through the building’s pipes. The air is cooled down, and the cooled water is used to cool the air.

A condensing boiler is a bit expensive, and it takes up a lot of space. However, if you have a lot of heating needs for a big building, then you’d better buy a condensing boiler because it will save you a lot of money.

Firetube Boilers

These boilers are also known as radiant boilers, and they heat the water through the use of firetubes. They are suitable for residential use or small commercial spaces. They can be installed indoors or outdoors. They can use either gas or oil, so they’re very versatile.

Firetube boilers are large, and they are very sturdy, so they can handle a lot of pressure. They can be found in larger buildings such as factories, hospitals, hotels, and other large facilities. Firetube boilers are pretty expensive, but they’re worth it.

Vertical Boilers

These boilers are known as fired steam boilers. They are very durable, and they are very efficient. It’s rare to have an issue with these boilers because they are pretty sophisticated. There aren’t many of these boilers out there because they’re costly, but only knowledgeable people can install them. They’re very efficient, and because of that, they require very little fuel.

Despite their cost, vertical boiler maintenance is much less expensive than other types of boilers. Vertical boilers come with a casing, and they make a lot of noise, so you might want to soundproof the room where you’ll install one.

Watertube Boilers

These are known as fireless boilers because they use hot water rather than fire. These boilers are very lightweight, and they don’t need to be installed into a furnace. They’re suitable for residential and commercial use. They are highly efficient, and they are very sturdy and durable.

A watertube boiler is highly efficient, but you will have to spend a lot on it. A watertube boiler is not for everyone because it’s costly. These boilers are usually used in large hotels and large houses.


All of these boilers have their own advantages and disadvantages, so it’s up to you to decide which one is right for you. Try to look into the different types of boilers and the money you’ll save by using them. If you have any questions, then you can always ask an expert.
