Possibly one of the best-known commercial water heaters with amazing features and quality components, so you can be sure that this brand has the price tag to match. The boilers are very durable and have been extensively tested to ensure the mechanisms inside can withstand even the most rigorous demands whether it is running multiple showers or heating entire schools and hospitals.

Whenever a fault is detected on one of these boilers, the easy-to-read error codes mean that the problem can be found and fixed quickly. It is very user-friendly, and anyone can reset it with ease. There are other boiler brands which have appliances which deliver the same output of heat as these ones, but can be bought for a fraction of the price.

Andrews comes out on the top of our list for all of these reasons, but if you are on a budget then our other three choices may be more appealing to you.


An excellent choice of commercial boiler capable of being used in a variety of settings, from busy restaurant kitchens with a demand for hot water or small hotels which need to heat multiple showers and baths as well as radiators.

These boilers are favoured by boiler engineers due to their pure simplicity, not only when it comes to finding faults, but repairing them if they should break down or lock out. They are also very appealingly priced compared to other brands so you can guarantee many commercial premises have opted for this brand, and the quality of craftsmanship is also excellent.

They can last for around 12 years with proper servicing, and they have remarkable recovery rates, not needing a huge amount of gas input to heat the water.


It was a close call between second and third place when choosing the Hamworthy for our rundown of the top four commercial boilers for a number of reasons.

Firstly, you have a wide range to choose from that caters for small business premises as well as larger establishments which have a greater demand for heating and hot water. It represents excellent bang for your buck and considering the fact their models boast heat exchangers made of the highest quality cast iron it has a very reasonable price point.

It only slipped to third position as the installation of these boilers is quite difficult compared to other brands, and warranties only last one or two years at most, compared to five on other manufacturers. The saving grace of this boiler is that once installed, you won’t need another commercial boiler replacement for a few decades.


This manufacturer has been in business for over 100 years, and the experience in creating boilers that are made to last really shines through. These boilers are more well-known for their use in residential properties, however they are really something special in the commercial and industrial spheres too.

The quality, dedication and experience they bring to the table is matched by an attractive price which puts them within reach of all kinds of businesses, from the local takeaway to churches and schools.
