How To Save Energy At Home
Categories :Energy Efficiency

Money, and how to save it, is one thing that all of us think about. Whether it is getting a great deal on insurance, finding that bargain in a shop or perhaps looking at ways you can reduce your outgoings from your home.

Saving energy and the costs related to it has definitely cropped up on many people’s radars of late. The benefits to looking at your energy usage at home is two-fold. Not only do you feel great about doing your bit to help the environment but you also get to keep some of the cash too!

We have put together this helpful guide on how to save energy at home; some of the tips are so easy to put in place that you could be saving money in no time at all!

Lights & Water

The lights around your home can be a drain on electric, so make sure they are only on when you need them to be. You can also replace your halogen light bulbs with LED ones that use less energy but are still bright, meaning that they are the perfect alternative to older style lightbulbs.

Water is another popular form of energy that is wasted in the home. In the kitchen you should try to wash up in a bowl rather than filling up the whole sink. You should also only ever fill the kettle with the water you need rather than filling to the maximum.

Showers can also use more water than they need to. Especially if they take water directly from the boiler or hot water tank. By investing in a water efficient showerhead you can save not only on your water usage but also the gas bill that heats up the water.

Energy-Efficient Doors & Draught Proofing

Like any other part of the home, doors can be insulated and draught-proofed to prevent heat from escaping. According to the Energy Saving Trust, just draught-proofing your doors alone can save about £25 a year on heating bills. When it comes to new front doors, they now generally contain integrated insulation to help reduce heat loss. But, if you have an older front door, it could be worth fitting draught-proofing strips around the seals and letterbox.

Have Better Control Over Your Heating

You may not realise it but half of the money spent on energy bills is for the hot water and heating in the home. The thermostat is the main way that you can control how much energy you use and by turning it down, even by just a fraction, you will see an improvement in your usage and costs.

Always make sure that the heating is only on when you need it to be; either by setting the timer or by purchasing smart heating controls which you can use to turn on (or off) your heating when you are not even there.

Energy-Efficient Double Glazing

Double glazed windows have two sheets of glass with a gap in between, usually about 16mm, to create an insulating barrier that keeps heat in, which is sometimes filled with gas. However, it is important to remember that every window has a different rating when it comes to how energy-efficient it is.

Energy-efficient windows come in a range of frame materials and styles. Performance criteria vary according to the following:

  • How quickly heat escapes through the window.
  • How much sunlight travels through the glass.
  • How much air can escape or come in around the window frame.

Fitting draught proofing to the doors and windows will save the typical household between £25 and £35 a year. To find out more about the energy ratings of windows, visit: BFRC Energy Rating.

Argon Gas – Q & A

Argon Gas

Argon Gas filled windows feature a double or triple glazed unit that is filled with gas between the panes of glass to increase energy efficiency and sound proofing.

Argon Gas increases the windows ability to insulate by reducing the heat transfer. Argon Gas does not conduct heat as readily as air, so it helps keep heat in during the winter and out in the summer at the same time as an advantage in decibel reduction.


No, Argon Gas is clear, colourless and odourless. Even if installed side by side, you cannot see the difference between a window filled with gas and one without.


Numerous studies show that gas typically leaks out at less than 1% per year. Over twenty years the window still has at least 80% of the gas still trapped inside it.


An emphatic NO! Argon Gas exists naturally in the air you breathe – it is both non toxic and inert.


Argon does not block any portion of the suns light. House plants will not be affected.


Argon Gas

No. Filling the glass sealed unit with Argon Gas alone will not give you an A-energy rated window. Whilst it will improve the thermal efficiency of the window, other measures need to be taken.

Sealed units used to have aluminium spacer bars separating the two panes of glass – these were conductors of heat and cold. Now spacer bars are made of an insulating plastic composite material that becomes a barrier to heat loss. We use the Warm Edge Spacer which does exactly as it ‘says on the tin’ – keeping the edge of the sealed unit warm. At the same time, the window frame needs to be manufactured in a way that meets a standard of thermal efficiency as well as be certified with a Window Energy Rating (WER) to confirm the whole window in its entirety has been correctly produced.


Whilst energy savings are important, the real “comfort” benefit of gas filling the sealed unit is the increase in the inner glazing temperature. Raising the inner glass temperature acclimatises or substantially reduces condensation on the glass. A “warmer” surface is also more comfortable to be near.

There is also a sound proofing element.


Unfortunately not! Gas filled windows are manufactured using specialised equipment and not all manufacturers have these facilities. So when buying new windows make sure your supplier can offer the benefits of Argon Gas for that extra insulation.

Or why not leave it to Cosyhomes. We have been providing Argon Gas filled sealed units with our Warm Edge Spacer bar and A-energy rated window frames to all our customers as standard since 2010. If you want to take thermal efficiency and sound proofing even further, get in touch about upgrades you can make to your existing windows by changing glass units alone or our new Rehau 36mm and 44mm triple glazing.

Simplicity is the ultimate sophistication.
