Master Gas London Recommendations

When it comes to selecting the ideal boiler for your property in London, Master Gas London provides tailored expert recommendations to suit your specific requirements. Our preferred brand is Vaillant, renowned for its quality, durability, reliability, and exceptional warranty services. While Worcester Bosch is a notable competitor, we firmly believe that Vaillant offers superior design and construction. For properties with a combi boiler, one bathroom, and up to 13 radiators, we suggest the Vaillant Ecotec Pro. This boiler is celebrated for its reliability and efficiency, offering the same top-notch build as the Ecotec Plus, along with a user-friendly interface for seamless operation.


What distinguishes Master Gas London is our ability to provide an impressive 10-year warranty on the Ecotec Pro, thanks to our status as Vaillant Master Tech installers. This extended warranty surpasses the industry standard, ensuring long-term peace of mind and protection for your investment. In comparison, competitors typically offer a maximum of 7 years warranty on the Ecotec Pro.


For larger properties with multiple bathrooms and radiators, we recommend the Vaillant Ecotec Plus. This powerhouse boiler delivers exceptional performance to meet higher demands while maintaining energy efficiency and reliability.


In situations where space is limited, the Vaillant Ecofit Pure emerges as the perfect solution. Its compact design makes it ideal for properties where space is at a premium without compromising on performance.


For those considering system boilers, the Ecotec Plus stands out as the preferred choice, offering versatility and efficiency. However, if space constraints are a concern, the Ecofit Pure provides a compact alternative without sacrificing functionality.


In the domain of conventional boilers, both the Ecotec Plus and Ecofit Pure offer excellent options depending on available space. Their reliable performance and high-quality build ensure optimum comfort and efficiency for your home.


For mid-range boiler options, we suggest the Baxi 800 or the Glow Worm Energy, both of which are well-built and can be installed at a more affordable price while still offering a 10-year warranty. It’s worth noting that Glow Worm is part of the Vaillant group. For those on a budget, our recommendation is the Glow Worm Compact, which is also well-built, reliable, and can be installed at a lower cost. However, it’s important to keep in mind that the Glow Worm Compact comes with a 5-year warranty. Count on Master Gas London for expert advice and installation tailored to your heating needs in London.
