Renovations, Tips and Advice, Lifestyle

Summer is now well behind us and autumn is in its final stages. Already the temperatures have started to drop and people have begun to turn on their heaters. Winter will soon be here.

Many people believe that their power consumption is at its highest during the warmer months, but the reality can be that you will actually spend more on power during the cooler months as you try to warm things, dry things and heat things.

Summer BBQ’s give way to dinners roasted in the oven. Fans go off but electric blankets go on and clothes dryers can really get a workout at this time of year.

Of course a well designed, eco-friendly home will use a lot less power than your average house, but regardless it’s still worth looking at ways to reduce power bills even further. So over the next few months, we’ll be sharing some energy saving tips with you that don’t cost the world, starting with saving money on your heating costs this winter.


Many homes, particularly older ones, have ‘cold spots’. Now we’re not talking about cold spots caused by something supernatural, we’re talking about drafts and gaps where heat can escape and the colder outside air can come in.

If you believe you’re losing heat or suffering from drafts you could get someone to come and check your home for you; and if you’re thinking about renovating or you have a lot of energy loss areas this might be a wise choice; but if you’re looking for a cheaper D.I.Y. alternative then Black & Decker have just the thing for you.

The Black & Decker Thermal Leak Detector is a handheld device that uses an infrared light to detect any cold (or hot) spots in your home. It’s easy to use, you simply point it at a section of the wall that you believe is free from drafts or gaps and get a reading. This is then used as your ‘control temperature’ and all other areas will be compared to this initial spot.

You can set the device to measure in Celsius or Fahrenheit detecting anything from as little as 1-degree temperature variation up to 10 degrees. As you point the detector at the wall and hold the button the light shining on the wall will be green, however, if it detects a lower temperature (based on your settings) it will turn blue. If it detects a higher temperature the light will turn red.

So what to do with this information once you have it? Well now that you know where you’re losing heat (and therefore money) you can now consider the most practical solution which could include things such as filling in any gaps or putting in additional insulation.

The cost of the Black & Decker Thermal Leak Detector is around $50 but it has the potential to save you a whole lot more than that, with studies showing that stopping drafts and energy leaks can save you as much as 20% on your power bill.

And of course, keep in mind that a well-designed renovation can save you even more in running costs as well as make your home more comfortable.
