Tank & Pipe Insulation

The longer that you can keep your hot water hot, the less you have to heat it and therefore the less you spend and the less CO2 you produce.

Insulating your hot water tank with a jacket is one of the most effective ways to save money and energy!

How it works?

The hot water stored in your tank will cool over time and then you will need to re-heat this to ensure that you have hot water for washing and heating. If you do not have a jacket on your tank it will cool much faster and therefore require much more heating.

The recommended jacket should be at least 75mm (3 inch) thick and this will reduce heat loss by over 75%!

The same principle applies for the pipe work around the boiler and tank. You don’t want the heat to escape where it is not needed or you will need to heat more.


You can fit a jacket to your water tank very easily, as you can to pipes. In some cases pipe work might be hard to reach so you may need to get some professional assistance.

Cost and Maintenance

A jacket should cost £15 and the insulation for the pipes will cost in the region of £10.

If you require professional assistance to fit the insulation this will add to the cost.


By adding a new 75mm where there was none before will save £35 per year. This give you a payback in 6 months!

For pipe work the savings are around £10 per year which give a payback in approximately a year.

You would save in the region of 200Kg of CO2 per year too!

How energy efficient are replacement windows?
When choosing replacement windows, you can check its energy efficiency by looking at the BFRC energy label. The higher the energy rating, the more energy efficient it is. At the moment there is no obligation for window manufacturers to label their products, however by opting for a high rated window you know you will be buying the most efficient window.
What's between the two panes of glass in double glazing?
Very efficient windows might use gases like argon, xenon or krypton in the gap between the 2 sheets of glass.
What keeps the two panes of glass in double glazing apart?
The panes are separated by pane spacers set around the inside edges to keep the two panes of glass apart. For a more efficient window, look for pane spacers containing little or no metal - often known as 'warm edge' spacers.
Which window frame type would suit my home?
The frame you choose will depend on your home's style and your personal taste, as well as any planning restrictions in your area. The popular material types are; uPVC, wood, aluminium, steel or composite frames.
Do you need extra ventilation if you install double glazing?
Because replacement windows will be more airtight than the original single glazed frames, condensation can build up in your house due to the reduced ventilation, so it can be a good idea to get replacement windows which have trickle vents incorporated into the frame that let in a small amount of controlled ventilation.
