How Do Commercial and Residential Boilers Vary From Each Other?

Although commercial boilers are often larger in size and have a higher output, home boilers and commercial boilers are essentially similar and share many of the same parts. It might be challenging to decide which type of boiler you need if you have a large home that needs several radiators heated or a small business location that may be adequately served by a typical domestic boiler.

Commercial boilers are essentially home boilers that have been scaled up, but because they produce such a massive amount of heat, there are many distinct characteristics. For instance, a household boiler will have connecting gas pipes that are all 20 to 30 mm in diameter, but commercial boilers that require a larger supply of gas must be equipped with pipes that are at least 35 mm in diameter.

It can cost a little more to service a commercial boiler, but often only by 10 to 20% more than it would to service your house boiler on a regular basis.

The amount of kilowatt energy produced by a boiler in a home vs a business is one of the key differences. Let’s see how the two various boiler kinds function.

Output Variations

The primary distinction between domestic boilers intended for use in houses and commercial boilers is the total output performance of a boiler. Most clients only need a boiler with an output of between 24kW and 40kW because a residential boiler may only need to heat 5-7 rooms within a home. This will provide enough hot water for numerous radiators in addition to the hot taps and showers. Gas and combi boilers are the most popular for this usage, while it is possible for it to be an electric, oil, gas, or LPG design.

An expert may advise installing a boiler with an output of up to 70kW, giving the home’s eight to twelve rooms hot water on demand, warm central heating, and the ability to run several showers at once, in a larger home with more rooms to heat. With such a massive boiler, all the heating that must be transferred through the pipework will be handled.

Generally speaking, any boiler with an output more than 70kW is a commercial boiler. It can be used to heat huge supermarkets, schools, and medical offices with lots of open area. Since you probably won’t be running showers in your business unless it’s a gym or a leisure center, you can choose a boiler that can produce up to 1500 kW of power, especially if you’re running a hospital, warehouse, or factory.

You’ll never run out of hot water with such a large output, and occasionally enterprises will decide to install two or three smaller commercial boilers rather than one enormous one. This is a smart move since it prevents everything from stopping if one boiler malfunctions and the other two continue to provide hot water and heating.

In certain situations, a smaller boiler may also be used to heat a big, properly insulated garage, a small- to medium-sized shop, or a construction site to hasten the drying of screed.

Unable to choose the boiler you need?

Are you unsure whether a household boiler or a commercial boiler is required? Wondering if the building’s square footage requires a boiler with an output of 70 kW or more? This kind of guidance is frequently given by Rowlen to business owners who are looking to install a brand-new boiler or upgrade an existing boiler.

It makes sense to hire a local company like Rowlen for your boiler servicing and installation as we will have a range of boiler engineers who can fit and fix both residential and commercial boilers. Larger, commercial-style boilers also require an engineer who is qualified to work on boilers over a certain output.

If you give us some basic information, such as the size of your property, how you plan to use the boiler, how many radiators there are, and how many hot taps and showers there are in the property, we can pay a visit to your premises and accurately assess your requirements, or we can even do it over the phone.

It’s crucial to have the appropriate size boiler for your needs because you don’t want to end up with greater energy bills when a smaller boiler would have been adequate. Call the skilled staff at ng installs right away, or use our online form, and we’ll get back to you as soon as we can.
