How do they work?

Unvented water heaters

The strong construction of the unit allows it to be connected directly to the mains water supply and store the water at mains pressure as it is heated.

• Expansion kits allow water to expand while it is heated without building up pressure.
• Pressure reducing kit provides a controlled cold mains water supply minimising final stored water pressure.
• Expansion back into the mains. Where conditions are suitable water expansion may be taken back into the mains without expansion or pressure reducing kits.
• Units >15litres must be installed by a competent person, and include all necessary safety kits.

Water boiler

• Stores water at near boiling point ready for call-off of high numbers of coffee/tea cups. On use the boiler fills and heats automatically without allowing the water to cool, so a fresh supply of hot water is always available.

Instantaneous handwash

• Cold water direct from the mains is heated as it passes through the unit.
• No stored hot water allows the unit to be left for long periods without fear of bacteria build-up and reduces ongoing energy usage costs.
• A spray pattern at the outlet reduces the water usage which further reduces running costs.
