Insulating a Caleffi Antifreeze valve with 28mm Primary Pro

Insulating and sealing all the external heating pipework on an air source heat pump is so important not only for the C.O.P & S.C.O.P. but also for preventing any ingress of water/moisture which will corrode the insulation from inside and any external fittings, like lever valves. With our 28mm x 19mm Primary Pro and Bond & Seal we wanted to help professionals provide the very best insulation in all weathers, while also looking quality on the outside of customers' homes. This video has a solution for insulating the Caleffi antifreeze valve to the manufacturer's instructions and also sealing all areas for energy efficiency and protection of water/moisture ingress.

Thank you very much for checking with Caleffi since it's quite important to have every inch of installation outside insulated.
