• Baxi boilers: Standard efficiency boilers offer robust entry-level to central heating. Condensing boilers achieve higher efficiency by condensing water vapour and are 98% efficient. Combination boilers heat both home and hot water (they only provide the heat needed, when needed)
• Currently, Baxi is developing and testing boilers in their research and development workshop that run on 100% hydrogen which pushes for zero carbon emissions making them safer and cleaner for the environment
• Rinnai Zen Boiler: Combination boiler that is both a highly efficient water heater and central heating boiler in a single compact appliance that can be placed inside or outside the home. The water heating part of the system heats water directly from the mains removing the need to store the water — making it a cost-effective option. The Zen boiler has 98% efficiency rating and comes with smart controls and Wi-Fi app control to help optimise your system, and save money and energy
• All gas boilers are virtually silent
• Gas boilers are small resulting in them typically being installed in attached garages, laundries, or cupboards
• Outdoor models feature a corrosion-resistant, weatherproof, and fully insulated casing that houses the boiler and required accessories
• Higher temperature output typically 70-80°C resulting in quick reaction time
