"Fitted one of these to feed a bath for a client - Unit failed after two months due to a faulty electrical component - Ok things go wrong. Salamander didn't even look at the pump, and their initial approach was to find reasons why the installation voided the warranty and to offer me a new pump at half RRP - which was about the same as the purchase price. But only once the cold water storage tank had been increased to 700 Liters because there were two other bathrooms in the house - this single ended pump was only used to supply hot water to one bathroom, and in any event the hot water tank held less than 150 liters. To cut a long story short they eventualy agreed to look at the pump if I would return it to their technical department, where having diagnosed the faulty component they agreed to supply a new pump. This process took a month and a lot of effort, and in the meantime I replaced the pump with a Stuart Turner who did not require such a huge storage tank in order to validate their warranty."
