Long ago, towards the end of last century when we first moved to Cyprus, we were told that electricity was 'very expensive'. The people Richard worked with used gas for all their cooking, and various forms of heating in the winter that didn't include electric heaters. None of them had air conditioning.
And, indeed, Cyprus was one of the most expensive countries in Europe for electricity, so we, too, were as careful as we could be. We turned off lights when we weren't in rooms, and when we did, eventually, instal one air conditioner in our living/dining room, so that we could use computers without destroying them, we calculated carefully what the cost of running it might be, and didn't use it more than was absolutely necessary.
But costs are lower now, and appliances are more efficient. I like having an electric oven, and various other kitchen gadgets. Lightbulbs now are so long-lasting that we think nothing of leaving them on when we're out, or when we forget to turn them off. We knew, of course, that it would be pricey using our electric water heater in the winter, and the air conditioners in the summer. And, indeed, our bills for those seasons were sometimes double those in the spring and autumn months.
However we didn't look too closely into the amounts, as they were never unreasonable; certainly not the huge amounts we heard about from some other folk here and elsewhere.
Towards the end of July 2019, we had to replace the air conditioner in our bedroom. It was quieter than the old one, and considerably more efficient. We started wondering how long it would take to pay for itself, so to speak. And then we wondered whether, if we replaced the elderly and very inefficient air conditioner in our living room, and ran the new one more often, would it in fact cost less than turning it on only when in the room?
Since the ambient temperature was only about 32 at the time, I wondered if running even the old unit more often at 30 degrees, rather than our usual 28, would make the whole house more comfortable. In particular it would remove the humidity which is often the worst part of the heat.
So I started monitoring our electricity usage. The meter is outside, in a little box so it's easy enough to read.
And to our great relief, we received a letter from the electricity board, informing us that our old meter was faulty, and we would receive a refund on our next bills. Which, indeed, we did.
