    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.

    Bought this unit to serve a wash hand basin and small sink in an outbuilding. Didn't have high hopes to be honest. After setting up as per instructions, nice hot water perfect for hand washing or doing some dishes. Would certainly buy again. Easy to install as well.

    The unit was a replacement for my previous Redring The old one lasted 8 years. I hope this on lasts that long. It was a fair price from plumbworld and was easy to order Deliver was first class. This was my order from Plumbworld and I would recommend.

    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.
