Music playing Narrator Over 50 percent of the greenhouse gas emissions you produce in your home are generated by heating, air conditioning and hot water. In other words keeping your home warm in winter, cool in summer with nice hot water on tap is emitting 2.5 to 5 tonnes of greenhouse gas emissions each year. It also contributes a hefty amount to your electricity bill, between 50 to 60 percent. CSIRO has invented a new solar air conditioning system for Australian homes. This technology solution will reduce Australia's emissions, reduce your energy.
Bills and reduce our demand for electricity and gas. If every home in Australia installed our solar cooling technology it would be the equivalent of saving 15 mega tonnes of CO2 or taking 3.5 million cars off the road. CSIRO's solar air conditioning is an innovative three in one technology that provides hot water, cooling and heating. It uses only a fraction of the electricity of current systems and halves greenhouse gas emissions. The process begins with a typical solar hot water system. Water is heated by solar panels and stored in the hot water tank.
This solar hot water can then be used throughout the home, reducing the need for gas or electricity. A portion of the hot water is diverted into CSIRO's new solar air conditioning unit, which is divided into two compartments. The hot water enters a heat exchanger in the first compartment of the unit. Similar to a car radiator the heat exchanger uses the hot water to heat outside air that has been drawn into the first compartment through the vent. At the same time outside air is also being drawn into the second compartment into a desiccant wheel.
The desiccant wheel is the most critical part of the system. It is used to dry out the air before it goes into the house. Slowly turning the desiccant material in the wheel continuously absorbs moisture in the second compartment and then the absorbent material dries out in the first compartment. The desiccant material is dried out using the hot dry air generated by the heat exchanger. This air is then exhausted outside the home. The dry air from the desiccant wheel flows through an indirect evaporative cooler which creates a stream of cool dry air.
Solar Water Heater System
We install our gas boosted solar hot water system. The collector panels are mounted on the garage roof directly above the storage tank. The gas booster is adjustable so we can fine tune the hot water supply to maximise its efficiency. Getting the temperature right means you don't have to mix in too much cold water. Once it is up and running, the system is bled and we are ready to roll. The panels are on the north face of the house and angled at about 9 degrees. Because we are installing the storage tank inside the garage it will need to be flumed out into.
The atmosphere to comply with safety regulations. This is part of our gas boosted hot water system installation. It's called the water guardian and what it does, when you turn on the hot tap instead of allowing the cold water to run out first before the hot water arrives it recycles it back into the storage tank. Just press the button, it comes on we wait for it to stop There we are, piping hot water strait away. This device saves 16000 litres of water per annum per outlet. Worth doing.
Solar Water Heating in 5 Easy Steps Home or Business
Are you ready to get started Great! You'll be well on your way with these five easy steps. Step One Take the Survey Make a Reservation The SoCalGas Energy Efficiency Survey is how your rebate and energy savings is determined, without it you can't get a rebate. Log onto your SoCalGas My Account page, click on the Ways to Save tab and take the Energy Survey. Or ask your contractor to help you. Now if you're a business customer, you'll also need to obtain an incentive reservation prior to installation in order to be eligible.
You can do that at csithermal That brings us to Step Two Hire a Certified Contractor Once you've hired a certified contractor, you're well on your way to enjoying the benefits of solar water heating. Now if you're installing your own system, this is the time to take the mandatory nocost selfinstaller workshop. To sign up, go to socalgas Search SOLAR. On to Step Three Install your System. Make sure that your system is installed using all applicable codes and standards, and that it has freeze, stagnation and overheat protection. Working with your certified contractor or taking the selfinstaller workshop will help ensure that you purchase the correct system and install it properly.
Once you've installed, it's time for Step Four Apply for your rebate. Now If you've taken the energy efficiency survey and selected an approved system, this should be a snap. Or if you're working with a certified contractor, they'll apply for you. Finally, the best step of all Claim your Rebate. So just sit back, and relax. or better yet, take a solarheated bath and wait for that rebate check. For your convenience, we have all the information you need to know in our Solar Water Heating Toolkit right here on this site.
Solar Water Heating for Your Home
Some solar water heating systems are more efficient than others. The California Solar Initiative offers rebates to home owners who install certain types of solar water heating systems, and I'm going to walk you through those right now. A closedloop active system uses a heattransfer liquid with a higher boilingpoint and lower freezingpoint than water to heat your water indirectly. The liquid circulates through the solar collector, gathers heat energy, and travels through a heat exchanger coil, acting as a water heating element in your water tank. This is called an active system because it uses a pump to circulate the heattransfer liquid.
This type of system is most common in California, and works better with hard water than other systems. A closedloop passive system relies on the principle that hot water rises and cold water sinks to circulate the heat transfer liquid without the use of a pump. For that reason, this system is also known as a thermo siphon system. The Integral Collector System stores water in the solar collectors themselves. Although this adds additional weight to your roof, the efficiencies gained might make this a good choice. As you can see, there are a few different options out there for your home, and your certified contractor will work with you to help you decide which system best suits your water heating needs.
There are other solar water heaters that use an openloop system but these do not qualify for the CSI rebate for home owners. These circulate the water in your plumbing, rather than the heat transfer liquid throughout the system. While we're on the subject of eligibility, you should know that space heating and cooling uses, and pool and spa heating uses, are not eligible for the CSI rebate for home owners. That's because the rebate is intended to encourage solar water heating for domestic hot water use only. So now that you know a little bit more about the different types of solar water heating systems available, the next step is to take a nocost selfinstaller workshop,.
Savings and Rebates for Residential Solar Water Heating
I'm going to walk you through how much money you can save by installing a solar water heating system in your home and the process you need to go through to get the California Solar Initiative, or CSI, rebate. On average, the cost of purchasing and installing a solar water heating system is $8,000 $10,000. Of course, it could cost less if you choose to do your own installation, or more depending on the location and type of system. Once you've installed your solar water heating system, you could receive thousands of dollars in CSI rebates.
Add that to your lower energy bills for water heating and the savings really start to add up. You may also be eligible for local, state and federal tax credits and incentives speak to your tax professional to see if you qualify. Now, because the rebate is based on how much energy the new solar water heating system will save you, you'll need to go online to take an energy savings survey. You can do it by logging into your SoCalGas MyAccount page. on the Ways to Save tab and take the Energy Survey. Or you can always ask your contractor to help you.
