Everything You Need to Know About Mains Pressure Hot Water Cylinders
Hot water is something most of us take for granted, but without it our lives would be far less comfortable. How many of us even know what system we have in place in our home to heat the water? There are actually several different ways of getting hot water into our homes, one of which is a mains pressure hot water cylinder. Keep reading if you are interested in learning more about these systems.
What are the different types of system?
There are plenty of choices in terms of water structures, it is up to you to decide what is the best option for your household. One of the most common systems are electric based. These work by heating the liquid with an element at the bottom of the unit, the liquid is then stored and kept warm so it is ready whenever you turn the tap on. A benefit of this system is that they are really affordable to buy and install, however, they are the most expensive to run. Solar systems are becoming increasingly popular, especially in Australia. Although these are more expensive to install than other types of system, they have lower running costs, so it could save you money in the long term. Gas cylinders are another option, these come in two main types, low pressure and mains pressure hot water cylinders. Both of these are very cost effective choices, and they are also really effective heaters.
What is a mains pressure hot water cylinder?
This is a system that supplies liquid to all outlets in the building. One of the benefits of this type of storage is that it supplies both warm and cold liquid at the same pressure. Many of us have experienced the annoyance of the cold liquid coming out of the tap at a good pressure, however as soon as the warm tap is turned on, only a very weak stream comes out. If you opt for a mains pressure hot water cylinder, this will be a problem of the past. This type of system is also very effective at heating the liquid up, meaning you wont have to wait before the stream becomes warm. A gas structure can be installed using both mains, and low force, so it is appropriate for almost any household.
How do they work?
They work by converting gas to energy in order to heat the liquid. An encased element inside an insulated tank will heat and preserve the temperature of the liquid. A thermostat will measure the temperature and ensure that the liquid is kept at that temperature throughout the day. A simple system consisting of two separate pipes keep the liquid going in and out of the tank; cold pipes bring liquid in and a withdrawing warm pipe will let the water out from the tank. This warm pipe allows the liquid to come out whenever a tap or appliance is switched on.
What are the components?
Any liquid storage system is made up of several components, depending on the type you have, these elements will differ. A mains pressure hot water cylinder is made up of six main parts, which are as follows: The storage tank, these usually have a steel inner section to help with insulation, and this is the section where the liquid is kept. The thermostat, this is basically a thermometer to keep track of the temperature of the liquid. The element, this creates the heat needed to warm the liquid. The temperature pressure relief valve, this is to protect the storage tank from excessive temperatures. The anode rod, this is to prevent corrosion and to extend the life span of the storage tank. The drain valve, this is used to drain the liquid out of the storage tank if repairs are needed.
How much do they cost?
These systems do require a larger initial investment than their electric counterparts. An electric tank of about 160L will often cost about $750 compared to the $1000 you will have to pay for a gas structure of a comparable size. However, the installation cost isn’t the only thing to consider, a more economic system can mean you save money over several years.
