    I chose this for a tiny wall space under the kitchen sink, and I did well. There wouldn't have been space for a bulkier one, and this one now sits there quite smugly, surrounded by its shiny copper pipes, and does the job - every time. Enough instant hot water for a few dishes and for washing my hands on a cold day - perfect.

    It's a Redring so not expecting any worries about the quality. Bought to provide instant hot water when indirect heating system not being used in summer to keep costs down and also to be more green. The delivery was quick and at a good price. Would definitely recommend Plumbworld on both service and price.

    This was a like for like replacement so knew what I was getting but it arrived next day and for a great price so thank you. If anyone fits one of these always worth turning the temperature down inside the unit or it tends to overheat and trip if it is starved of flow for whatever reason.

    I bought to replace the previous model which had ceased working after 20 years. Ideal for supplying instant hot water to two wash basins.

    Not yet installed, but just what I want to save running long water supplies. I`m sure the water saving will be considerable.

    Cold water in, hot water out. Straight forward fitting but bear in mind the power entry is at the bottom right or from the rear. I bought this to replace a Hyco unit that gave good service for about 12 years so 4 stars as just fitted and longevity still to be proved. Quick to heat and good temperature. Copper fittings used not plastic push on. All in all a smart compact heater.

    This instant water heater is very good for what it's meant for, my only criticisms are the connectors for the water inlet & outlet could be longer to make it easier to connect & it could do with an external reset button, apart from that all is good. Also the service from plumbworld is excellent.
