A small investment can keep you warm this winter & save you £££

Pipe lagging is a type of insulation fitted around water pipes that saves energy by sealing in heat to ensure the heat in your hot water is not lost before it gets to its destination. Lagging can also prevent pipes from freezing and potentially bursting in very cold weather which could lead to costly repairs.

The main benefits of pipe lagging are to:

  • Reduce heat loss from the pipes and save energy
  • Ensure that the water in your hot water pipes remains hot where it is needed
  • Prevents the water in your pipes from freezing which can expand enough to burst the pipe

Central heating system pipes are usually made from copper as it is highly conductive making it ideal for transporting hot water. But, just as the pipes can get very warm, they can also get very cold and cold pipes can attract water vapour that can lead to corrosion when it condenses on the surface. Lagging prevents condensation from forming on cold pipes.

Which pipes should you lag?

Pipes in your loft as the insulation in your loft prevents heat from your living space rising into the loft so your loft area can get very cold. It is worth lagging the pipes to prevent heat loss and freezing.

All hot water pipes to prevent heat loss and ensure the maximum amount of heat is delivered. Lag all hot water pipes including pipes in the airing cupboard, pipes from the boiler and central heating pipes.

Outside pipes such as those leading to garden taps.
