When you turn the tap on and a good stream of hot water flows down, you are content and glad to have a water heater installed at home. The water coming down the tap or shower makes a long journey before you can finally have it. Water heaters play an integral part in providing you and meeting your hot water needs. Besides bathing, hot water is generally needed for other purposes too, such as dishwashing and laundry. When these units are doing so much work for you, spending some time to understand how they work is not a big problem. So let’s begin:
Water heaters commonly look like big cylinders. These are tall drums and usually installed in the basement, garage or a laundry room. Although modern heaters have certain changes but their working is almost the same. These drums store with water and heat it through a mechanism. Heaters are simple devices and not at all complex to understand. All heaters come with certain components which help in its functioning. These components include the tank, a shut-off valve, thermostat, heat-out pipe, drain valve, pressure relief valve and sacrificial anode rod.
Every part has a role to play and the heater can be termed incomplete in case any of them is not present. Undoubtedly, a tank is the most important component in a heater and does most of the work to bring you the hot water you need. Water heaters are broadly divided into two categories that is gas and electric water heaters. After the tank, the thermostat is what heats your water on the desired temperature. The lower the temperature the better for your heating bill because low temperatures save energy to a significant extent.
When going out for long such as on a vacation, it is best to turn the dial to the minimum otherwise your water heater can add up extra amounts to your heating bill which are actually of no use. A thermostat is generally a knob or more like a dial which you can use to achieve the temperature you need. Dip tube is another component present in the heater. This is where the water from your water supply fills in the interior of the tank and it begins to warm up.
Water heaters have a certain life after which their maintenance is mandatory. If you maintain and keep your heater in proper shape, it will not only bring down the costs but will also help you conserve energy to a great extent. Moreover, if any of your heater parts require a replacement, do it as soon as you can. The more you delay the repair the worse it will become. For this reason it is important that you understand what maintenance can actually mean to a water heater.
If you are not sure about what has gone wrong with your model, ask a plumber to come and have a look. They are professionals and will be able to guide you better. If you are new to a heating system and have bought one recently, consider hiring a professional for its installation. Doing it yourself might be easy in certain cases but it is always better to have someone who has the right expertise to do the job. Good luck with your heating unit!
