Case Study

Combining technologies to maximise efficiency

Replacing an old, inefficient boiler with a new condensing Vortex or VortexBlue oil-fired boiler can instantly help reduce fuel consumption. Householders can further improve their system’s efficiency by opting to install a high-performance hot water cylinder alongside their new boiler. Grant cylinders are designed to deliver maximum heat transfer as well as low standing heat losses to reliably and effectively meet a property’s hot water needs.
