Boiler Replacement

Boiler replacement is quite a large and costly undertaking. There are a lot of different things that need to happen before you can even start installing the boiler system itself. All sorts of preparations have to come first – such as choosing the new boiler and planning its installation – and then you need to consider how best plan the actual installation to minimise any disruption to the operations of your business.

If you have chosen boiler replacement as the best option for repairing or upgrading your boiler system, then fitting a new boiler can be a significant undertaking. It is crucial from the start that you get everything just right so that boiler replacement does not end up costing more than it should, and so that boiler installation goes as smoothly as possible.

Which Commercial Boiler Should You Choose?

We have various hot water solutions and boilers for different types of commercial buildings and properties throughout Manchester and the North West, UK. All our commercial boiler replacement options are of the highest quality, design and performance you can ever want for your operating space.

Some of the options we have at our offices include:

  1. Combi Boilers

Combi boilers are best suited for buildings and properties in the UK that have single bathrooms. With this type of boiler, you will find that the hot water will only be generated when you require it. Therefore, no tank is needed to hold the water.

The main stand out feature of combi boilers are their compact sizes. It is what makes them great for smaller properties.

  1. System Boilers

We recommend this type of boiler for business premises which have several bathrooms. Our heating engineers have designed the boilers to provide you with an uninterrupted supply of hot water.

It is, therefore, perfect for commercial offices where there are many occupants, who are likely to have higher hot water requirements. The boilers require a cylinder to hold the hot water supply.

  1. Open Vent/ Regular Boilers

They are similar to the system boilers in that they are best-suited for large Manchester properties with many bathrooms. We recommend that they are installed in a commercial building if there are instances where multiple rooms get to use the hot water at the same time.

A regular boiler from us can be used with a heat pump or solar water heating pressurised systems.

Businesses have a fairly wide choice when it comes to commercial boilers and it can be hard to choose between them. Many will be guided by the commercial boiler cost yet, while an important consideration, this shouldn’t fully persuade you to buy a cheaper model to save on your budget as this can lead to a false economy.

commercial boilerSo, what are the most important considerations to bear in mind?

A good energy efficiency rating

Thanks to the Energy Labelling Directive (ErP),

choosing an energy-efficient boiler is pretty easy. The information accompanying all commercial boilers these days means that assessing performance versus energy efficiency is clear, with technical documentation readily available.

By assessing a boiler’s expected energy consumption over time within your commercial premises means predicting its carbon emissions. This is key in an age where climate change is a top consideration.

Life cycle costs

Commercial boiler manufacturers can provide life cycle cost models for any business that’s looking for a boiler replacement. These will include:

  • The initial costs of purchase.
  • The cost of commercial boiler installations.
  • Running costs for heating and hot water, depending on fuel prices.
  • Anticipated maintenance and servicing costs.

Installation and maintenance

The costs of fitting a replacement boiler can vary, depending on the make, model and how easy it is to fit. Annual or more frequent servicing and maintenance/spare parts costs can also vary. To get a better idea according to the model in mind, contact us to speak to one of our technicians.

Warranty period

The type of warranty accompanying a commercial boiler is an important consideration. A longer warranty gives peace of mind and taking advantage of this plus the commissioning services of your commercial heating engineer means your boiler will be set up according to the recommended procedures right from the start.

Ongoing support

Ongoing technical support is vital through the manufacturer and also the team of your commercial heating company. We have highly trained and skilled engineers to offer support, troubleshooting and repairs, if necessary and provide expert advice.

Water treatment

The water in a commercial heating system needs chemical treatment at regular intervals for optimum performance and as part of an ongoing maintenance schedule. Once again, leave this to us, the professionals.

So, there’s no need to feel overwhelmed when choosing a boiler replacement. We’re on hand to give you help and expert advice every step of the way. Call our boiler experts on 0161 279 0137 or email for assistance.

Boiler Replacement FAQs


At ST Heating, we understand that maintaining and replacing your commercial boilers can be a mind-boggling exercise. It is the reason why we have taken the time to gather together the commonly asked questions about central heating and boiler systems. We hope that you will be able to find the answers you seek here. Click on the links featured below to skip to the relevant question.

The good news is that any replacement job can be done very quickly with minimal business disruption. The downside is that the job may end up being shoddily done. Unfortunately, we cannot provide a timeline for the installation of commercial boilers.It normally depends on the boiler we are installing, space configurations, the boiler system that was in place before, and the requirements of your building. Often, site work for a boiler replacement takes one day. But if the new commercial boiler we are installing has some additional alterations that are different than the previous boiler, it could take a few more days to complete the installation.

Commercial boiler replacement costs will traditionally vary depending on the boiler we are installing. Normally, the costs will vary between £750 for a regular/heat only boiler to around £4,500 for a new commercial boiler system. Also, note that the costs may also be affected by whether the boiler is getting moved from one room to another, or whether it will be installed in the same location as the previous boiler.

Buying the actual boiler itself is relatively inexpensive for a business. There are different models to choose, ranging from budget, mid-range to premium models. The boiler model used will depend on the work environment and characteristics required. It is also important to consider boiler installation costs, as they are more significant, but boiler replacement can be cost-effective over time compared with repair bills and boiler repairs.

Gas Safe registration typically costs £360. When you include the value added tax, the amount becomes £434.40. The gas safe registration is a one-time fee which is intended to cover you for a period of 12 months and includes one registered gas engineer. You will need to pay an additional £152, inclusive of VAT after one year for the certification to get renewed.

We recommend that you consider replacing your boiler if it is more than 15 years old. Be on the lookout for additional signs such as:

  • Presence of leaks in your commercial or industrial boiler.
  • If the boilers need frequent repairs and maintenance.
  • You have noticed the presence of black soot and yellow flames.
  • Your energy bills are becoming higher with each passing month.

You should generally replace your boiler when it starts to break down or show signs of wear. Although it is possible for a boiler to last 30-50 years, reports in recent years have found that boilers can develop leaks and other major problems if they aren’t properly installed and maintained. The bottom line is this: you should consult experts who know what type of fuel will work best for your system, the number of people operating at the premises and how often heat or hot water will be required.

Installing a new boiler replacement is a simple case of isolating and draining the systems, disconnecting the electricity and the thermostat, removing the existing boiler and installing the new one in its place. Usually, one engineer can easily complete this job in under a day. Changing your old boiler for the same type generally makes installation easier.

Of course boiler replacement is not a job to be taken lightly, which is why it is advisable to use highly qualified engineers such as our team at ST Heating. Our boiler replacement professionals are experts in boiler installation and fitting, so you can be sure that your boiler replacement will go smoothly. The heating engineer will connect the boiler to your water pipes, radiators and cold water mains. The boiler should then be tested to ensure that everything is working correctly.

When boiler replacement is being carried out, it is important to take into consideration your boiler warranty, as boiler warranties can vary in length and boiler installations are generally expensive. Most boiler manufacturers only offer a one-year boiler guarantee, but some may offer up to five years.
