Solar Hot Water Systems utilize the free energy from the sun to provide your hot water. Some electric systems can account for up to 70% of your electricity bill. We service and install all the solar hot water brands -Bosch, Rinnai, Kelvinator, Envirosun, Conergy, Rheem solar hot water systems , Edwards, Solahart ,Beasley solar hot water systems with either gas or electric boosted back up for those not so great days without the sun
These types of hot water heaters are more environmentally friendly than your common electric hot water systems, a solar hot water system when install correctly should save you up to 80% of your hot water running costs, that's about $200 a quarter for the average household of 4 persons
There are two main types of solar hot water systems – close coupled and split systems.
Close Coupled Solar hot water systems commonly known as Roof Mounted Solar hot water heaters have the panels & tank mounted on the roof, not very aesthetically pleasing, in fact they look like a rolled up roller door on your roof, but when room on the ground is a problem or if you have a existing roof mounted solar & needs replacing, this becomes the cheapest option, this type of solar water heaters are old technology using thermosyphon to transfer heated water from panels to the tank, hot water naturally rises, water from the panels heat & rise into the tank on one side & the colder water in the tank falls to the lowest point in the solar panels from the opposite side of the tank, unfortunately this can waste a lot of water when tank is over heated in summer & hotter days. To install these types if your don't have a existing roof mounted solar hot water heater we will have to engage a building certifier or engineer to report that you roof is structurally sound to carry the 500+kg that these system weigh when they a re full of hot water By not doing this is something was to happen to your home your insurance company could void your policy
Split System Solar is when the storage tank is on the ground and the solar panels are on the roof, giving a more streamlined look to your roof. These models use a small circulating pump to feed the water through the collector panels to heat up and then back to the storage tank. These pumps are part of the system very small & quiet. They draw very little power to run, less than a radio, the water is pushed through around the 3 litres per minute rate heating up as it goes through the copper manifold inside the panels.
It is important with either system that it is installed correctly to gain maximum savings and hot water. No point having a solar hot water system if it not facing the sun, in south east QLD your panels should be facing within 45 degrees of north
There are 2 types of solar collectors available flat panel & evacuated tubes
Flat Panels are a manifold of copper pipe that is inside the insulated frame & glass. They generally have flat copper plates behind the tubing & powder coated black to attract & absorb heat quickly
The bottom is generally a 25mm copper tube with 15mm copper piping that is attached & to both top & bottom tubes, looks a bit like the old style pool fencing , very simple design works well & proven for dozens of years, very little is any maintenance is needed other than making sure your glass is clean
Evacuated Tube Collectors collect the heat through a number of annealed glass tubes that each have their own heat-absorbing plate inside. There is an extensive array of different designs on the market, but the basic principle applies for all. Basically, each tube is like a little greenhouse that traps sunlight inside the glass tube which is used to heat either the water, or a special heat transfer fluid called propylene glycol, that transfers the heat to the water, via copper pipes and a heat ex-changer. They come in different banks generally 12, 24 & 36 tubes, they are very efficient, some may say a bit too efficient, we have had cases where people have had 24 & 26 tube systems fitted by other companies & they make a rumbling noise on the roof & at the tank when the water is transferred back. Not a good idea in treed areas as they can trap leaves between the tubes therefor making the system less efficient
