Review: Instant hot water and compact unit - been installed and working now for a few months. I replaced an existing one that lasted about 7 years. Great Instant Hot water.
Review: Delivered promptly - I bought this to save energy heating litres of water by the combi boiler to reach the bathrooms miles away, so you end up washing hands in cold water anyway and all the hot in the pipes is wasted. In that respect, this will be a great saving, as it does heat quickly to warm enough for hand and face washing, but the flow rate is necessarily slow. At 3.75 kW, it seemed to blow a 13amp fused spur and cut out, so it may need a higher rated connection. We did that and it works. We've plumbed it in a way that can easily switch back to boiler if necessary, or f energy prices ever revert to something like normal.

### ⭐ The quality is rubbish
*by A***R on 18 April 2024*

I bought this a month ago, and it stopped working after a month. Now I have to hire electrician again to remove it, send to the seller, and then asking the electrician again to come and install it. Which will costs me two times more. Hence decided to write a review
