POWERflow meets specific requirements


Having recently used a POWERflow unvented horizontal cylinder, and both the installer and the homeowner were impressed with the performance, it was fantastic to hear we were the first choice when it came to selecting a cylinder for another restricted installation space within a loft space.

John from Blades Heating Ltd (Oxted, Surrey) said, “As part of a large refurbishment project, we installed of one of McDonald Water Storage horizontal unvented hot water cylinders, within an angled roof void over the kitchen and backing a new Guest Bedroom En-Suite Bathroom.

Having the POWERflow manufactured to meet our specific requirements, serving the hot water requirements for the new ensuite bathroom as well as the kitchen, was the perfect solution.”
