Wasting water heat energy


We pay a lot of money to heat our homes and provide us with hot water and certainly in the last eighteen months these costs have been pretty high.  This got me thinking about how we waste money in the form of heat.

Example 1

When filling the basin in the bathroom to wash, I used to run the hot tap for a while without the plug in.  This was so that the water would be hot, but every time I ended up added cold water!!!  Now I put the plug in, start with the hot tap, which is cold for a while and usually I have enough water and at the right temperature without adding any cold.  This of course saves heat energy, but also reduces the amount of water I’m actually using.

Example 2

An old classic, only filling the kettle enough for my immediate requirement (ie one cup).  This has been well documented for years and handy gadget kettles are available which help with this.  I have a slight addition to this.  If say I’m working at home and I know one cup isn’t going to be enough, I refill the kettle with water for the next cup.  This takes the energy from the hot kettle and very slightly raises the water from the tap a few degrees.  Thus using less energy next time.

Example 3

Another slight variation on example 2, but during the winter, the tap water is very cold and therefore it takes more energy to boil.  I tend to fill a jug with enough water for the days tea and coffee and have it near the kettle and it effectively gets towards ambient temperature during the day.

Closing remarks

The above suggests are very simple and easy ways to reduce the energy I can use in my house and whilst they are very small and perhaps insignificant to some, but together they offer a saving in terms of financial and CO2.  But the most interesting part for me is it doesn’t take any effort or change to my life at all, just a bit of thought.
