"Due to their point-of-use installation these units also benefit from minimal standing heat loss, and when added to the fact that, because this heater is only 3kW, unlike instantaneous water heaters, it can be spurred off a ring main rather than requiring its own dedicated circuit and then it becomes clear why the Redring WS7 Water Heater has quickly become a firm favourite."
Outlet Spout: 300mm
Is this really sensible advice. Years ago we put 3kW immersion heaters on a dedicated radial circuit. Is this advice a backwards step?
