Some years ago I rented my Casa to holiday tenants. On receiving the electricity bill I was horrified to see the amount. The extra amount was I understand from the air conditioning working at full pelt day and night.

Therefore, I was delighted when I heard there was a company importing a neat little unit to stop this happening. Not only saving electricity, but extending the life of the air conditioning units but saving the environment an amount of pollution.

The saving on the bills can be very attractive not just for holiday rentals, but people just forgetting to turn off the unit when leaving a room. It is very easy to install, and already comes with two batteries.
