Nu-Heat's successful Optiflo manifold has received an upgrade to help it achieve even better performance. System flow rates are measured by sight, but when a system has been in use for some time flow guages can become grimy or occasionally stop giving an accurate reading. Nu-Heat has introduced isolation valves beneath the guages on the manifold so they can be cleaned or replaced if necessary, without having to release the pressure from the system. As before, it arrives preassembled on brackets and has identical space requirements, layout and mounting adaptability. Spare parts are readily available. The product continues to be made by a UK supplier and the price remains the same.
