Hot Water Systems
- Indoor gas water heaters are available but they require an available gas supply and flue through an external wall.
- A solar tank can be placed indoors, but if it’s gas boosted it will need a gas supply and flue through an external wall.
- Split heat pump systems – that allow the tank to be installed indoors and the heating unit outdoors – are also an option.
For the most effective solar hot water solution you need the following:
- Enough roof space – The average home needs about 2m x 2m of clear roof space to take 2 collectors which are around 2m tall x 1 m wide. You will also need some clearance space on your roof and some ground space for the ground-mounted hot water storage tank. If you decide to use a roof-mounted tank then you will need additional roof space depending on the size of the system.
- A north-facing roof area – north facing rooves are exposed to the most sunlight. The more sunlight your system gets the more effective it will be. If you’re not sure, use a compass or check your property plans to see which direction the roof faces.
- A shade-free roof – the roof area where the solar collectors are going to be fitted needs to be shade-free. Consider what trees are planted on your property or neighbouring properties. If they are going to grow large enough to cast a shadow on your roof then your system may be less effective. Also, consider building developments which may cast shadows on your property.
- Climate can also impact a solar heater. Extremely cold or hot temperatures will need units that need a product designed to suit the climate.
Our qualified plumbers can help you make sure you have the right set-up. If your house doesn’t suit solar, a Heat Pump is a great alternative and they can also attract solar rebates and incentives.
How much you save depends on your existing system. If your old system is an electric water heater then you are likely to save more. Your current energy tariffs and how your new solar system is installed may also have an impact. The biggest savings on hot water bills are seen when replacing an electric water heater on a continuous tariff.
It is also important to know that solar water heaters can reduce greenhouse emissions by up to 65% depending on where you live, according to Australian Government approved modelling.
It depends on the size of the existing pipes and the type of system that you want to install. Some gas storage systems can be fitted to existing piping, but continuous flow systems require larger diameter pipes from the gas meter. Our qualified plumbers are also gas fitters. They can inspect your home and give you the right advice for a system for your home.
t depends on how much hot water you use and when you use it. There are two types of gas hot water heaters:
- Continuous Flow – wall-mounted and compact these heat water as you use it so you should never run out of hot water.
- Gas Storage – these heat the water and stores it ready for use supplying it at mains pressure. This means you can run several taps or showers at once without loss of pressure.
These three valves are essential when installing your water heater.
