Key Differences Between Residential and Commercial Boilers


Boilers play a significant role in homes and businesses. They provide hot and cold water for showers and taps. We can say that it is virtually impossible to live or work in a place where there is no hot water for showers and washing during the cold days. For boilers to last a long time, we must also do our fair share, maintaining them, so they don’t conk out at the most inopportune times. Residential and commercial boilers may have the same functions, but there is a world of difference between them as well.


The main physical difference between residential and commercial boilers is their size. They are equivalent to the size of the place that they will be servicing. You don’t need a gigantic boiler for your small home, and a small-sized boiler will not be enough to heat or cool your office or place of business. Depending on the size of the business establishment, it may require more than one unit.

Heat source

Propane gas, electricity, and natural gas are the main types of heat sources that both residential and commercial boilers use. The most common heat source for business units is natural gas. Boiler owners can directly pipe the gas to the unit. It is also cost efficient and more convenient to use. In industrial applications, ease of use is far more critical than the price. The most common boiler type for residences is the natural gas type. Propane and electric powered ones are less common.


Obviously, commercial boilers are more expensive than residential ones, as they are bigger. You don’t have to shell out as much money for home heating compared to heating a commercial establishment.


Small commercial buildings can use a residential boiler if there is not much need for a lot of hot water at any given time. But since commercial boilers can hold a lot more hot water than residential units, houses cannot use commercial boilers as it will be disadvantageous in terms of energy consumption.

Water holding capacity

Residential boilers can hold up to 100 gallons, while their commercial counterparts can hold up to 250 gallons.


Both commercial and residential boiler contractors have specialised training in handling and maintaining these two boiler types. Hire the appropriate technician so they can check your unit thoroughly and provide you with the right expertise they use appropriate tools for the job.

There is one key similarity to commercial and residential boilers: their expansion capacity. You can add another unit to an existing boiler without any difficulty. Adding one or two more boilers to your home or business establishment will not only add to your hot water source but if one breaks down, you still have a backup and will not run out of hot water when you most need it.

If you run a business and you want your heater to stay on top of its game, you must hire a commercial boiler service London company so they can check any issues and provide effective solutions.
