Water Heaters – The facts you must know!

 


Visitors: 184

Water heating is probably the largest energy utilised in an Austin home. Several kind of domestic activities call for water heating facility. It is for a good water heater to provide sufficient amount of hot water during any time of the day. The importance of choosing the right kind of water heater when replacing an existing faulty or worn out one cannot be over stressed.

You can say a list of house hold chores cannot be carried out without hot water. From cooking to bathing and from cleaning to heating up a space, water heaters are absolutely essential.

Water heating is a thermodynamic process in which an energy source is utilised to raise the temperature of water from its initial level. By the way, thermodynamics is a branch of physics in which the causes and the effects of changes in temperature is studied.

In a house, common things like kettles are used to heat water. But you cannot get continuous supply of hot water from our domestic kettles. Water heating facility provides us continuous supply of hot water, as and when necessary.

Like all other domestic appliances, water heaters also come with the required safety precautions. In machines like these, such safety measures against expected risks are very necessary. Two main risks that can happen in a water heating facility are the risk of water getting contaminated with Legionella and the risk of scalding. These two risks contradict one another and a balance is always achieved. If the water is over heated scalding will occur. But if the water is not heated enough the bacteria germs will not get killed and will result in water contamination. As a balance to these two conflicting factors, the thermostat is usually set at 50°C (120°F).

Yet another safety concern here is that, the appliance may explode in case if some important safety devices go uninstalled. A water heater explosion is very dangerous that in addition to damages and injury it can cause even death. If the temperature of water is above 100°C (212°F), the water will be in liquid state inside the tank. But as when the water comes out of the tap, the pressure gets released resulting in water boil and can cause burns. If water with temperature above 88°C (190°F), pours on our skin, it will cause 3rd degree burns. T & P or TPR valves (temperature and pressure relief valves) are fitted on water taps, as a safety device, which will stop the water from coming out if the pressure or temperature is very high.

Tips to safeguard your water heater:

  • insulate the water heater
  • prefer showers over baths
  • insulate the water pipes (both hot and cold) connected from your water heater up to a 6 feet length
  • Every three months, drain a quarter of water from your tank so as to remove the efficiency reducing sediments

You may not realise the importance of water heater unless, one morning, when you wake up and go to take a shower and find no hot water.

When the cold water enters the heater, it settles at the bottom of the tank as the hot water is less dense. When you have consumed all the hot water up in the tank, the cold water will start to flow. If you get cold water from a heater, either the heater is too small for your house or else the bottom heating element of the heater might have been burned out.
