Flexibility for Any Installation
One of the reasons Andrews is among the top water heater model providers is their systems' adaptability. Their heaters can be installed:
- As standalone units
- In cascaded arrays for scalable output
- Wall-mounted for space savings
- Floor-standing for high capacity
Whether your plant room is tight on space or you’re installing in a new build with generous access, Andrews has a format that suits the project.
Andrews systems also allow for integration with commercial circulators, expansion vessels, and DHW pumps for maximum efficiency in circulation and pressure management.
Integration with Modern Controls and Renewables
All Andrews models are designed for seamless integration with building management systems, helping operators monitor energy use and system performance. They’re also compatible with renewable technologies such as solar thermal and heat pumps, supporting your decarbonisation efforts.
Using an Andrews water heater in tandem with renewable sources enables hybrid systems that lower energy bills while maintaining high-demand performance. In combination with pressurisation units and smart thermostats, the heaters adjust dynamically to changes in load and temperature.
Low NOx and High Efficiency
Many Andrews models meet NOx Class 5 or 6 requirements and exceed 90% thermal efficiency, helping buildings meet Part L compliance and reduce carbon emissions. This level of performance means you’re not just getting heat—you’re getting sustainable performance that’s ready for tomorrow’s environmental standards.
Energy efficiency also translates into long-term savings. For example, upgrading to a MAXXflo EVO or ECOflo can reduce gas bills significantly in older properties where older boilers are still in operation.
Built to Last
Each Andrews water heater is built with corrosion-resistant materials and designed to reduce maintenance frequency. Easy-access panels, durable heat exchangers, and quality components ensure these models hold up under demanding usage.
Andrews units also come with built-in safety features such as anti-legionella cycles, flame failure detection, and overheat protection, giving operators peace of mind in high-traffic, critical facilities.
