Expert new boiler installation

Upgrading to a new boiler can transform your home’s comfort and energy efficiency. We install modern, energy-efficient boilers, including combi boilers, that are perfect for homes of all sizes. As a Vaillant Advanced Installer, we offer extended warranties of up to 10 years on Vaillant boilers, provided they are serviced annually.

We also work with other leading brands, like Worcester Bosch Boilers and Glow Worm Boilers, giving you plenty of choice. We’ll assess your property’s heating needs and recommend the ideal solution tailored to your budget and requirements.

Benefits of a new boiler

  • Reduced energy bills thanks to improved efficiency

  • Lower environmental impact with modern systems

  • Reliable performance during colder months

  • Compact designs, especially with space-saving combi boilers

Hot water cylinders

For larger homes with higher hot water demands, adding a hot water cylinder alongside your boiler is a smart choice.

Cylinders store hot water, ensuring a steady supply even when multiple taps or showers are in use at the same time.

This setup is ideal for busy households, delivering consistent water pressure and comfort throughout the property

Underfloor heating

Underfloor heating is a seamless and efficient heating solution that is worth considering. By eliminating radiators, you gain more design flexibility and a cleaner aesthetic.

Whether you choose an electric system for smaller areas or a boiler-run system for whole-house heating, underfloor heating delivers even warmth and enhanced comfort throughout every room.

What our customers say

  • After several problems with our old boiler, Wayne came out on the same day to try and diagnose the problem. He then supplied and fitted a new boiler for us as he didnt want to leave us without heating and hot water with a young family. He was very professional and friendly. I would highly recommend him. We can't thank him enough.

    Cheryl C-D

  • Fantastic service from Wayne - as usual. Serviced my Vaillant Boiler - very thorough and far superior to the previous British Gas service I had previously. Wayne knows his stuff and I unreservedly recommend his service and prices.

    Rob H

  • I can honestly say one of the most competent, professional tradesman anyone could have to deal with your boiler problems. Trustworthy and extremely reliable and I would recommend him to anyone

    Brian V

  • Fantastic experience from start to finish, I couldn’t recommend Dorchester Boiler Solutions enough. Wayne installed a new Vaillant boiler for us, the boiler location was difficult and Wayne worked hard to ensure we minimised any damage

    Jamie F

  • Called DBS with broken boiler at 4pm on a Thursday, Wayne was with us by 5.30pm. A week later new boiler installed. Really nice family run business who care about what they do. Would highly recommend.
