Every hot water installation specialist in Melbourne will tell you the same thing. It is important that you choose a suitable Hot Water Systems Melbourne for your Melbourne home. There are two main types of water heaters, one that operates as a storage device the as an instantaneous devices.
Storage water heaters operate by heating water to a relatively high set temperature (usually between 60 degrees Celsius and 70 degrees Celsius). The water is kept at this temperate in the tank. When you use hot water, it's drawn from the top of the tank and replaced by a layer of cold water at the bottom. The temperature drop is sensed by a thermostat, which turns on the heater at the bottom of the tank. Although the tank is insulated, it's constantly losing energy. So the water temperature drops over time unless it's reheated. If you draw off hot water faster than the cold water can be heated up, the cold layer can eventually move to the top of the tank.Instantaneous water heaters can operate using natural gas, LPG or three-phase electricity. The benefit of an instantaneous system is that it only heats water, as it is needed, helping to generate massive savings on energy. Despite this, instantaneous systems deliver water at a slightly reduced pressure and when multiple taps are in use, the pressure and temperature of the water can drop even further.
There are also gravity-fed hot water systems but these are not as popular. These systems are non-pressurised tanks located in the roof space. They were common before mains-pressure systems became popular some decades ago. They are still available. Some solar hot water systems are also available with gravity-fed storage tanks. You're probably aware of the main disadvantage: as the hot-water pressure depends on the height difference between the tank in the roof space and the water outlet, it's usually not enough to allow several hot-water outlets to draw from the tank at the same time. However, these systems don't require much maintenance, and can last for a very long time. And you can connect solar collector panels.
In terms of what to power your system with, you have the options of electricity, gas or solar. Electric water heaters can heat water at any time of day but are by far the most expensive option. Off-peak electric (which heat only when tariffs are lower) and gas systems have similar costs, depending on the tariffs you have to pay.Natural gas produces much less of the greenhouse gas carbon dioxide (CO2) than electricity to heat the same amount of water. But it's not available everywhere.In areas where you can't get natural gas, liquid petroleum gas (LPG) is an alternative. But expect to pay about one-and-a-half to three times as much as for natural gas or electricity.
There are two types of solar hot water systems. The first consists of two flat plate collectors that work on copper pipes running through a glass-covered collector. This system is often connected to a water storage tank on the roof. The sun heats the copper pipes and the resulting hot water is thermo-siphoned out of a storage tank. The second is operated using two glass evacuation tubes that are fused at the top and bottom. A copper pipe (called a heat pipe) runs through the center of the two tubes, meeting at a common manifold that is then connected to a slow flow circulation pump that pumps water to a storage tank below, thus heating the water during the day. The hot water can be used at night or the next day due to the insulation of the tank.
