  • I just wanted to let you know what a great customer service experience we had from Dan Berry today who covers our area. We had one of your treatment plants installed and weren’t convinced it was operating as it should. Dan reassured me on the phone, visited as soon as he was able and sorted the problem. He is super knowledgeable and a credit to your organisation. Customer service as it should be.

  • I decided to give HeatStream Electric a go after Scott Lorraine recommended it. I am mighty pleased with the product as, with it, I am able to provide my family with plenty of mains pressure hot water. I was able to upgrade from my old vented low pressure system to the HeatStream Electric quite easily. It does away with all the problems of a traditional unvented cylinder.  Would highly recommend.
