Solar Water Heating System

Water heating is the largest source of greenhouse gas emissions from an average Australian home and the second largest segment of household energy use in Australia, after space heating and cooling.

Reducing your hot water use and using renewable energy sources to heat water are great ways to reduce your environmental impact. By installing the most appropriate and efficient water heater for your household size, water use patterns and climate you can save money and reduce greenhouse gas emissions without compromising your lifestyle.

An efficient hot water service HWS can also add value to your home and help meet state, territory or local government regulations. Energy use in the Australian residential sector — Data are projected energy use for More than half of hot water use is in the bathroom, a third in the laundry and the remainder in the kitchen. One of the best ways to reduce energy bills is to reduce hot water use by installing water efficient showerheads and taps — and save on energy and water.

Behaviour change also saves energy and water: take shorter showers, use cold water for clothes washing, use water-efficient appliances, rinse dishes in cold water, and use mixer taps in the cold water position when hot water is not required see Reducing water demand.

Both of the two basic types of water heater — storage systems and continuous flow or instantaneous systems — can use a variety of energy sources to heat water including solar, gas LPG and natural gas and electricity. Water is heated and stored in an insulated tank for use when it is required. These systems can operate on mains pressure or from a gravity feed constant pressure tank. Mains pressure — Hot water is delivered at a similar pressure and flow rate to cold water so more than one outlet can usually be turned on without greatly affecting pressure.

The storage tank is usually located at ground level inside or outside the house. Mains pressure systems have been the most popular systems in recent decades but heat losses from storage tanks and their associated fittings and pipes can be substantial. Large electric storage tanks and their fittings can waste up to 1,kWh each year; a typical 5 star gas storage HWS wastes 3,MJ.

This is equivalent to the energy required to heat 50—60L of hot water each day. Constant pressure or gravity feed — Hot water is delivered at lower than mains pressure from a tank located in the roof of the house.

Pressure depends on the height difference between the tank and the point of use. Gravity feed systems are most common for older properties and properties not connected to mains water.

For either type of system, storage tanks may be made of copper, glass enamel lined steel or stainless steel. Copper and glass- lined tanks typically have a sacrificial anode to reduce tank corrosion, which needs to be replaced every few years. Warranties offered for tanks typically range from five to ten years.

They can operate on natural gas, LPG or electricity. Gas models are available with either electronic ignition or a pilot flame.

They can be mounted externally or internally if suitable ventilation is available. Gas is not a renewable energy source. State and Territory Governments, homes and businesses are investing in solar, wind and water power. These factors are making electric heating a more sustainable option.

Because continuous flow systems heat the water as it is used, they cannot run out of hot water. Continuous flow water heaters can be fitted with sophisticated temperature controls, including controls that allow the user to set the desired water temperature at the point of use e.

Water is not overheated and hot water does not need to be diluted with cold water to achieve a suitable temperature, thus saving energy and reducing the risk of burns or scalding. Air-sourced heat pumps are an efficient type of water heater that extracts heat from the environment air, water or ground to heat water. Electricity is not used directly to heat water unless the heat pump is fitted with an electric boost element ; it runs the compressor and thus its use is much less than for traditional resistive electric systems and of similar efficiency to an electrically boosted solar system.

The pumps operate like a refrigerator but in reverse. Ambient air is used to heat a refrigerant, which converts to a gas. The gas is then compressed, expelling heat, which is transferred to the water. The refrigerant is expanded back to a liquid and the cycle repeats.

Like solar water heaters, heat pump water heaters cost more to purchase than conventional HWS but save energy and can reduce energy bills. Seek expert advice on choosing the most cost-effective heat pump and electricity tariff for your local climate and needs. Air-sourced heat pumps work best in warm, humid climates. In cold climates, the efficiency of a heat pump decreases to a point where the refrigerant is less able to absorb heat.

However, some heat pumps are designed to operate efficiently in cold climates and in frequent freezing or very cold and dry conditions. Note that some heat pumps have an electric booster element installed to help boost the water temperature in regions where it is cold or during periods of high hot water use.

The cost of running a heat pump may increase if it is required to operate its compressor on high cost electricity tariffs, or operate an electric booster. Electricity tariffs differ across the states and territories, and some heat pump water heater models are more suited to operation under restricted hours tariffs. For further information talk to your plumber or electrician, ask your supplier about the heating specifications of the product you are considering and contact your energy retailer to find out which tariffs may apply.

CO2 heat pumps , which use carbon dioxide CO2 as the refrigerant, are relatively new to the Australian market but have been operating successfully for a number of years in Japan.

They operate in the same manner as air-sourced heat pumps. In an integrated system, the heat pump is fixed to the hot water storage tank, which has similar characteristics to a standard electric HWS and is connected in the same way. Installation of an integrated system can be very straightforward, especially when replacing an existing electric HWS. In a split system, the heat pump evaporator unit is placed away from the hot water tank.

This can be useful in circumstances where the tank location does not offer the ventilation required to operate the heat pump system. The tank, for example, can be placed inside a cupboard and the smaller evaporator in a well-ventilated space or outdoors.

Split systems require a small amount of additional electricity for pumping. Some heat pumps can be fairly noisy, so check noise level and consider potential noise impacts on neighbours.

Heat pumps avoid the need for the roof-mounted collectors of solar HWS units. They also avoid any risk of overheating or dumping of water in hot weather, as the compressor switches off when the stored water reaches the required temperature.

Ground source or geothermal heat pumps use a waterbody, shallow trench or deep bore instead of the air as a heat source. They usually provide both space heating and water heating. Electricity is used to pump water or refrigerant around a loop buried in the ground or immersed in a waterbody.

The enclosed water absorbs heat from the surroundings. Geothermal heat pumps can produce more than four units of heat energy for every unit of electrical energy used. They are best suited to multi- residential applications, where plenty of space is available and the high capital costs can be spread over a number of users. Heat pumps can be located and designed to use waste heat from air conditioners and refrigerators. Natural gas water heaters generate far fewer greenhouse gas emissions than electric resistance storage systems using mainland grid electricity.

Natural gas burns more efficiently than the coal burnt to generate most electricity in mainland Australia. Gas storage systems have quicker heat recovery times and generally use a smaller tank than a comparable electric storage system. However, they can lose heat quickly due to a lack of insulation. For fire safety reasons there is no insulation at the bottom of the tank due to the burning gas flame and insulation around the outer layer of the tank can be minimal.

Natural Gas is not a renewable energy source, although gas water heaters might produce less greenhouse emissions than electric water heaters, the growth in sustainable electricity production will make electric appliances a more sustainable option. Instantaneous systems must heat the water as it is used.

They thus require high gas flow rates when delivering large amounts of hot water, which may necessitate installation of larger gas pipes and even larger gas meters. Standard units can deliver adequate hot water to only one or two points at the same time but high performance gas units can supply several points at once. Some continuous flow gas units operate erratically at low flow rates, especially when the inlet water is relatively warm e.

Their burners cannot turn down low enough to avoid overheating the water, so they shut down for safety reasons. Thus some units may not work well with water-efficient showerheads or solar preheating. Check with your plumber or local people using the same models. Liquefied petroleum gas LPG systems are typically two to three times more expensive to run than natural gas. For example, if you have a clothes washer and dishwasher that heat the water themselves or if you wash in cold water , most of your hot water will be used for showering.

With only a couple of people in a household and water efficient showerheads, hot water use is probably low. Instantaneous models, particularly high power electronic control models, use a much larger gas burner than storage systems, and generally need a larger gas supply pipe. So, where possible, decide what you are going to buy before having the gas supply pipe installed.

If you already have gas connected to supply a stove or room heater, the supply pipe may have to be replaced with a larger one. LPG units will generally require two 45kg capacity gas cylinders to avoid frequent replacement of gas bottles.

Solar hot water systems use roof mounted solar collectors to absorb energy from the sun to heat water which flows to a storage tank. They cost more to buy and install than conventional HWSs but can save energy and reduce bills.

The time required to break even the payback period depends on the climate, type of system installed, hot water use and energy tariff applied. Solar water heaters have additional benefits: they last longer than conventional water heaters and add to the value of your home. Seek expert advice to help you choose the most cost effective solar water heater for your needs.

Consider the energy source for boosting gas or electricity , energy efficiency, energy tariffs, ease of installation and product cost.

There are two common types of solar collector: flat plate units and evacuated tubes. Flat plate units have been well proven in Australia for over 50 years.

Evacuated tubes have dropped in price and are becoming more common in Australia, particularly in colder climates. To provide hot water on cloudy days or when demand exceeds supply, most solar water heaters come with a gas or electric booster. A gas booster usually produces fewer greenhouse gas emissions unless renewable electricity is used or the booster is a heat pump. Automatic booster systems located inside the storage tank can be inefficient — cutting in and pre-empting the sun. Override switches and timers can correct this problem if well managed.

A popular approach is to use an inline gas booster that works like a continuous flow water heater but the system must be specially designed to work as a booster for solar hot water see Continuous flow water heaters above.

Water heating is a heat transfer process that uses an energy source to heat water above its initial temperature. Typical domestic uses of hot water include cooking, cleaning, bathing, and space heating. In industry, hot water and water heated to steam have many uses. Domestically, water is traditionally heated in vessels known as water heaters , kettles , cauldrons , pots , or coppers.

Industrial manufacturing. Other humidifier applications. With the continual development of new products and manufacturing techniques in the pharmaceutical industry that require tighter and tighter environmental conditions for production, specialist environmental control systems have never been more important. It has always been known that certain processing methods require control of the environmental conditions in terms of both humidity and temperature, and conventional heating and ventilation systems have in the past been suitable.
