Some trouble with the pressure release which my plumber will fix, but this is really good. I have got rid of all hot water plumbing and central heating and gone for localised heat management and this does the job perfectly for the kitchen sink and the business of washing up and having good hot water (easily adjustable) when you want it.

It seems to be working well. I needed to purchase a pressure reducing valve.

A good product which does the job as described. I have fitted it in my log cabin and it supplies hot water to my kitchen sink and toilet whb as required and quickly.Only con is that the instructions did not make it clear that the water wasn't heated until the red light went off. Otherwise very happy with this product.
