Our Services

  • Regular boiler servicing is essential for keeping your system running safely and efficiently. In fact, most manufacturers will only honour their warranties if the boiler is serviced annually.

    At Nebula Heating, all services are carried out by fully qualified and highly experienced heating engineers. We follow strict manufacturer and legal safety guidelines on every visit.

    Your boiler will be thoroughly cleaned and inspected, with digital flue readings taken to check carbon monoxide (CO) and carbon dioxide (CO₂) levels. We’ll also top up your heating system and check the pressure in any expansion vessels to ensure everything is running as it should.

  • We will carry out a full safety inspection of all gas appliances in your property.

    Including gas rate checks and a tightness test to ensure there are no leaks.

    Once the checks are complete, we’ll issue you with a Gas Safety Certificate, as required by law for all rental properties.

  • Our engineers specialise in full heating system conversions. We replace outdated vented systems with tanks in the loft, and can install a compact combination boiler in your loft or another discreet location—perfect for freeing up space in your airing cupboard while maintaining efficiency and reliability.

    We can fit systems on a bigger scale like 350litre unvented hot water systems for larger homes with bigger families

  • Noticed your heating system underperforming, but been told there’s nothing wrong with the boiler?

    The problem might be a build-up of sludge and debris inside your system.

    Over time, sludge can clog pipes, reduce efficiency, and even damage your boiler. A professional power flush solves this by using a high-pressure machine to circulate clean water and specialist chemicals through your system, clearing out built-up dirt.

    The result? Better performance, lower energy bills, and a longer-lasting boiler.

  • Looking to future-proof your home? Renewable energy systems use natural resources like sunlight, air, water, and geothermal heat — all of which are continuously replenished — to power your home more sustainably.

    At Nebula, our specialist engineers are fully trained in renewable systems, including:

    • Biomass Boilers

    • Solar Thermal Heating

    • Ground-Source and Air-Source Heat Pumps

    Heat pumps extract heat from the air or ground and transfer it into your home using electricity — no need for gas or oil. They're efficient, eco-friendly, and play a vital role in moving towards a net zero future.
