Boiler Installations

For new and replacement boilers in Durham, OTS Heating Services offer a competitively priced service.

Our team of Gas Safe registered heating engineers are committed to providing you with a friendly and professional service that you can rely on. We are registered installers of market leading boilers – all at very competitive fixed rates.

Available 24 hours a day, 7 days a week, our team of professional and local engineers are fully trained and qualified in carrying out boiler installations. Because every boiler installation is different, we ensure that the utmost care and responsibility is taken at all stages.

In the UK, we are extremely reliant on our central heating system to provide us with warmth, especially during the winter months. However, a faulty central heating system can add unnecessary costs to your heating bills and it also increases your family’s risk of contracting Carbon Monoxide poisoning.

Replace Your Old Gas Boiler

Our A-rated high-efficiency condensing boilers and modern heating controls will not only cut your home’s carbon dioxide emissions – you will also benefit from significant savings on your fuel bills.

Upgrading to a modern central heating system

When you want your boiler or central heating system replaced or you want to upgrade to a high efficiency boiler, call our experienced and friendly team, who offer expert advice and help you make the right decision in choosing the correct system for your needs.

They can help you choose the perfect boiler based on a number of factors to consider such as:

  • The type and size of your property
  • Age of the property
  • System usage i.e the number of occupants
  • Costs

We install two types of central heating system

  • Combination ‘Combi’ Boiler

Often referred to as a ‘combi boiler’, this ever increasingly popular system is now the number one choice in the UK. This type of system gets its name due to it being a high-efficiency water heater and central heating boiler combined within one compact unit. A benefit of this is you now no longer need a separate hot water cylinder, offering you extra space within your home.
Since no tank is required in the roof space, it means that installation time and costs are lower as less pipe work is required, which cuts the installation time.
Combi boilers are ideal for properties that ideally have one or two bathrooms and a kitchen. This is because combi boilers are mains-fed, and so using water at multiple locations can cause an issue with the water pressure.

  • System Boiler / Heat Only

This system requires either an unvented hot water cylinder or a vented hot water cylinder which also requires a cold water storage tank. This system incorporates wiring controls including a 2 channel programmer, zone valves to separate heating and hot water. This is suitable for high occupancy and larger properties.

We can fit most new boilers in one day, this will keep disruption to your property to a minimum and keep cost of work down.


Boiler installation costs are quoted as a fixed price with no hidden extras. Rest assured, we offer very affordable and competitive prices.

For all boiler installations, we carry out a full professional clean, to ensure your new system is in pristine condition when we leave. We do this free of charge, as we believe it should be part of the installation service we provide. This applies to all of our customers throughout Durham.
