My solar heating system is not performing too well, hardly any tepid water at best. I know the daytime temperature has dropped this week but I thought there would still be plenty of energy in the constant sunshine as the last couple of days have been cloudless.

Is this normal for this time of year or is my system not working?

You certainly should have good hot water. Depends on your system, but it could be a faulty circulation pump from the panel to the hot tank, or controller wrongly set, or the differential temperature guages faulty . I had the latter problem where the pump didn't cut out when the panel became colder than the tank water at night, and all my heat was radiated back into the night sky! You could peek at the instruments and try to make sense, but best to get a specialist, if you can find one who doesn't also crack your roof tiles. Good luck.

Every year I read about these problems on all the forums and remain glad that we don't have a "modern" system with pumps, controllers and pressure vessels to make them work. Ours uses gravity, provides adequate pressure and excessive hot water most of the year.

It is notably less scalding at the moment but still hot in copious supply.

Do make sure the panels are clean from all the dust that will have settled on them.

I have noticed my water isn't as hot over this past week, but as the sun drops lower in the sky with the season and then moves around the back of the panels, it is missing them.

Ideally my panels need realigning.

In our new house we have a flow-type calorifier, working with gas.
For 2 people we need one ordinary bottle, 14 E at Paps every 2-3 months.
Hot water 365 days a year without need to use electricity if the sun doesn't shine for as much hot water as you like and always at a touch of a button. We like it!

I can see the advantages but if Cyprus can't use the sun to get free clean energy, who can?

And gas can't be blamed to be clean....

Anders, he's talking about using the heater during the times when there is no sun. That will happen during the cold season when he will be heating cheaper than most of us who have electric immersion heaters. Although Cyprus boasts 365 days sun, apart from not being totally true, for some of that time it won't heat the water enough.

I have heard of a compact heat exchanger water heater which would use electricity far more efficiently but the capital cost of it is too ridiculous to contemplate.

Of course you can use the sun to get energy, but if there is not enough sun, you have to heat it up with electricity. Is that better? I just love to have a full bath, especally in wintertime, my hubby prefers the douche and it's great to do the dishes, wipe the floor, then take a bath and my hubby his shower.
Never could do that before in the houses with solar panels!
But naturally it's also a question of the immense difference in the cost of purchase.
We couldn't afford to have a really good working solar system for the whole year and the size we want and a gas heater in additional.

Sorry I misunderstood, and thought you used gas all year round. I ofc understand you want water also in the winter. I do too.

I have never heard of this over here.

I find it hard to believe that it is cheaper to heat all the year round than have free heating for at least 9 months of the year and boost the remaining time.

But obviously you are happy with your decision. You may be even happier in 10 years time if gas prices drop!

Believe me, IF we had free hot water 9 months a year, 24 hours a day, we would have the solar heater.
But we often did not have it when we needed it in the old house, early in the morning, for several things at the same time......., 300l was often not enough or /and expensive to heat them per electricity when the sun doesn't do the job.
Sometimes we needed 500 l within 1 hour, sometimes just 50l, but had to heat up the whole quantitity
I'm sure there are technical solutions for that, it's just a matter of money!!
For us thousands for a solar water system that fits our needs is simply too much,
so the costs of about 600 E for the gadget and then:
7 E per month (or even less in summertime) for constant hot water whenever we need it, is just perfect.

500 Liters per hour?? :eek: a bath is about 80 liters, and the average shower is 35 liters. this is mixed warm water. Are you sure you need 500 liters per hour hot water? that sounds pretty..... high....

Yes, sometimes we need alt least a quantity higher than a usual boiler has. Our bathtube has 180l, 80l, brrrrh and 3,5 bucketful for a shower? Not enough for me, maybe for hubby (he's bald :cool:) You should also see our 5 dogs, when they come in in wintertime. They can go outside all day long cause we live in the middle of nowhere and there is a lot of 'nature', perfect for them, they like to get dirty :rofl: and often each of them needs a bucket of warm water at least once a day.....
Cleaning the floors: 3 buckets.........
We have a large garden, a lot of work outside, so even we need a bucket extra many times.
The 250l hot water, we had in the old house, definitely was not enough. Too often we had to heat up a second amount, which took long and needed the electricity.
Additionaly my mother visits us for 1-2 months a year, usually in wintertime.......
I was just fed up with the situation, that the hot water was finished, just when you needed some litres more.
With the gas: very comfortable and cheap now!
Our electricity bill is 20-40 E lower than it was before.
As said before there is also the huge difference in acquisition costs!

So there is only one negative thing then, its not very good for the environment.

I hope the environment pardons me my bottle of gas every 2 months and the fact, escpecially casuse we cannot afford anything else. As a punishment :rolleyes:we collect the rubish every monday in wintertime, left by all the hunters who use our land for their sport and dumpside and go for shopping with a jutebag instead of using millions of plastic bags.......
Sometimes you have to balance pros and cons.
I just wanted to explain this possiblility especially for people who are low on funds.:yo:
