Redring

Match the kW to how many outlets and the flow you want. For simple hand-wash use, the over-sink 3kW units (RMHW3 or infrared RAHW3) are ideal. If you need to serve one or two basins with stronger flow, the Powerstream range (9.5kW, 10.8kW or 12kW) gives progressively higher performance, 9.5kW suits a single basin with steady flow while 10.8–12kW will keep two basins comfortable.

Yes. The page notes the instantaneous Redring heaters can be used with up to two hand bathroom basins and deliver hot water instantly, so they're a practical choice for cloakrooms or small family bathrooms with dual basins. If you regularly use both basins at once, opt for the higher-power Powerstream models (10.8kW–12kW) for better simultaneous flow.

They are designed to be energy efficient because they heat water on demand, avoiding the standby heat loss of stored cylinders and long runs of pipework. The compact Powerstream units also cut wasted heat and the need for long pipe runs, so you only heat what you use. Bear in mind that higher kW models heat faster but draw more electricity while in use, so choose the output to match your typical usage.

Yes, Redring emphasises compact, space-saving instantaneous heaters that are easy to site where space is tight. You can choose small over-sink 3kW hand wash units (including an infrared RAHW3) for a cloakroom or prep sink, or the Powerstream 9.5–12kW range if you need greater flow. For kitchens where you want instant boiling water, Redring also offers boiling water taps as a separate option.
