Installation of the Grant Wave cylinder range.

Grant’s range of Wave cylinders are manufactured from duplex stainless steel and are indirect, mains water cylinders. The single and double coil cylinders are high gain, leading to faster heating times and quicker recovery. Installing a hot water cylinder is step one to maximising a property’s efficiency, however, it is vital to correctly size hot water cylinders. Too small and there will be limited water for the property – too big and energy will be wasted.
