Category Information

Key reasons to insulate pipe include: 

  • Energy Saving. Adding insulation around hot water pipes can increase the temperature of the water by a couple of degrees, which doesn’t seem a lot, but it will allow you to turn down the overall temperature on your heating. 
  • Freezing Pipes. When used on pipes in loft areas, pipe insulation helps to prevent the pipes from freezing during the cold winter months 
  • Controlling condensation. On the opposite end of the scale, low temperatures can cause condensation on the surface of your piping, which in turn can cause corrosion and potential long-term damage. 
  • Dull Noise. If your pipes are known to rattle or allow sounds to travel from different areas of the building, insulation can help to prevent that. 

Which pipes should be insulated? 

We recommend insulating any pipes that transport hot water around your home, which as a rule of thumb includes: 

  • Hot water outlets. This is typically kitchens, bathrooms, WC and shower rooms and includes pipes beneath your sinks or behind bath panels. 
  • Boiler and Hot Water Tank. You should insulate all pipes that run between your boiler and hot water tank. This includes any pipes running into your airing cupboard. 
  • Radiators. This is an easy one to forget because many of us only remember to insulate the pipes coming directly out of the radiator, however, it’s important to remember the ones that are under floorboards.
