It is very important to have all the pipes inside and outside your home fully insulated. Outside the house insulation protects the pipes from freezing. If it is inside the house it aids the efficiency of the heating system and hot water system. We do recommend that you insulate pipes when ever possible; hot or cold.
It is most important to insulate the pipes in your loft and outside. We recommend you only use proper pipe insulation like climaflex and not the pipe tapes you can get. Proper pipe insulation is designed for the right size of pipe and has much better insulating properties. It also looks better.
