Versatility for Older Buildings

Dave Blackmore from Terratherm said, “Design and careful installation are critical when you are dealing with a project on a property like this with solid stone walls, relatively high heat losses and legacy systems to integrate. STIEBEL ELTRON helped us ensure the design was spot on for this challenging project to ensure that the customer got the result they were looking for. This project proves that heat pumps can be used sucessfully for older buildings when you chose the right products and have clear, achievable objectives to meet.“
