Water heating costs account for about half of most household's energy
bill. Through an efficient solar hot water system, you can reduce energy
costs for hot water by 70% per year.
To work at maximum efficiency, your solar panel should be placed to
face north at around 35 degrees. From the evacuated tubes, the heated
water is pumped down to the hot water cylinder (HWC). The hot water
is moved with a circulating pump which costs around 10c a day to run.
Solar water heating has come a long way in the past 15 years. Heat
loss for solar panels used to be an issue; particularly during the winter
months. However, with the introduction of evacuated glass tube technology,
heat loss is minimised. Heat can not pass through a vacuum, so evacuated
glass tubes work like exceptionally efficient double glazing.
Yes, of course you can. Admittedly, it is better to install a solar
hot water system when building your house, but it can be retrofitted.
It is recommended you have a large hot water cylinder. The larger the
cylinder, the more freely heated hot water you can store. I always suggest
to my clients they have a 300 litre hot water cylinder to store that
free heat for later use.
