New Boilers in Guildford from Fortress Plumbing & Heating

At Fortress Plumbing & Heating, we want you to be 100% happy with your new boiler. This is why we only fit premium branded appliances renowned for performance, efficiency and reliability. We have our own heating engineers, with Gas Safe registration and NICEIC accreditation, who fit new boilers on behalf of our valued customers in the Guildford area.

All gas engineers at Fortress Plumbing & Heating comply with current gas safety standards. While we are proud Worcester Bosch boiler specialists, we can still fit appliances from other industry-leading manufacturers.

Glow Worm Boilers

With 80+ years in the industry, Glow Worm is one of the UK’s best-known new boiler manufacturers. Their reliable, efficient products reduce annual heating bills and ongoing repair costs. Our gas and heating engineers can perform conventional, combi and system boiler installations within a wide radius of Guildford using the Glow Worm brand.

Models include the Energy Combi, a popular new boiler with a 7-year guarantee out of the box, an aluminium heat exchanger and an efficient Grundfos pump – ideal for properties with multiple bathrooms needing optimal boiler performance.

Vaillant Boilers

Vaillant is a solid brand and the perfect choice for a new boiler installation in conventional, combi or system configurations. Premium boilers from Vaillant, when fitted by an accredited gas engineer, come with a guarantee of up to 10 years. Options include the patented ecoTEC and ecoFIT models, which are eco-friendly and made from 85% recycled materials.

Assembled by hand in the UK, these boilers are easy to use and deliver high levels of energy-efficient performance to reduce heating costs inside your Guildford or Surrey home.

Viessmann Boilers

This German manufacturer has been in business since 1917 and is one of the most innovative in our industry. A new boiler installation using a Viessmann model combines cutting-edge technology with quality materials to save you money on energy bills, and to help reduce the impact of your carbon footprint.

Much like Glow Worm, Vaillant and Worcester Bosch Boilers, these products come in conventional, combi and system designs to give our Guildford and Surrey customers a full range of options.
