Hot Water Systems are one of the most frequently used appliances in households and they use a significant amount of energy (second only to space heating and cooling). The type of hot water system you choose will affect your household’s energy costs for years to come, so it is important that you choose a high efficiency model that suits your household and lifestyle. A highly efficient model can reduce your electricity consumption by up to 20%, saving you money and reducing greenhouse gas emissions.
The most common hot water system is the storage tank electric type. It works by sending cold mains water into a large strengthened hot water tank (cylinder) which is heated by an element or by two elements depending on the size of the tank. Once the hot water reaches the required temperature (140F-160F) it is then dispersed around the house via a pipe network and is delivered to taps, showers and outlets at pressure.
This type of system can be electric or gas and might also be tied into your home heating system. A drawback of this system is that it is possible to run out of hot water if everyone in the house demands it all at once. This is often referred to as a ‘peak period’ and occurs when demand for hot water is highest. To avoid this problem you can use a system that uses smart controls such as the Heat-Timer ETV which is able to sense demand and manage your usage.
In addition to this you can use a continuous flow or instantaneous hot water system. These are generally electric and work by heating water as it is being consumed so they don’t have the same energy losses as storage systems. This type of system can be connected to natural gas, liquefied petroleum gas (LPG) or a gas bottle, but you will need a larger gas supply pipe installed.
A drawback of this system is that it can take a while for the heater to kick in and start producing hot water. This can be a disadvantage in some households, particularly with children who may want to turn on the shower first before getting out of bed.
A good way to determine which type of hot water system will suit your family is to look at the energy efficiency of each model and ask a professional to help you make the right decision. Choosing a high efficiency model will not only save you money but can increase the resale value of your property.
