We developed the Hotflo range for people who need a hot water supply for two to three basins or sinks.

Flexible siting is a key design feature that we insisted upon because it means there is no requirement for a cold water cistern. Hotflo can be used with standard or mixer taps and fed from the mains water supply provides high hot water flow rates.  With the best possible performance, long-term reliability and corrosion-resistance in mind, our designers specify high-grade copper for the Hotflo's inner container. Using copper for this key component also means we don't have to fit a sacrificial anode - avoiding the need for the hassle and expense of regular inspections and replacement. In addition, copper is better than lower grade materials at withstanding shock and vibration during delivery,installation and maintenance.

The complete confidence we have in the quality of Hotflo's design and materials is proven by its two year guarantee with on-site service support.
