Water Heaters

Water heaters are an essential part of a home. For those busy people and always in a hurry, heating their water to use is always a problem everyday. This may cause them delay on their works or appointments. It is such an irritating feeling knowing that the cause of your delays is just simply heating the water. Gone are the days you will experience these stuffs again. A water heater is the solution for your everyday problem. It is a household appliance used to heat waters. There is a hot water tank in it that heats up the water into its full capacity. Thus, this provides instant water for you. Conventional and Less conventional types

Types of Water Heaters

 Conventional • Fossil Fuel Fired – This uses gas or propane burner located at the bottom of the storage tank to heat the water. Using different kinds of venting technologies, the smoke emitted from this type of heater is barred. There is a need of an exhaust fan to help the throwing out of combustion gases. • Electric Resistance – There are two electric resistance elements located at the bottom and top of the tank to heat the water. An independent thermostat is present to control each element. The lower element provides recovery for standby losses while the upper element provides heating when there is a large use of water.  Less Conventional • Heat Pump – There is a use of an air source heat pump to transfer thermal energy from the air to the storage tank. There is also the presence of electric resistance elements to serve as backup if the heat pump cannot provide enough heating capacity. • Solar powered – This is the most used among the heaters. The solar collectors are usually found outside the buildings or on the roofs or walls. There is a specific design of hot water storage for solar thermal.  Direct-gain type – The potable water goes directly to the collector. Naturally, it has storage within the collector. Direct heating is more efficient than heating via heat exchangers. However, the system has a limited heat loss protection, thus, this suffer from heat loss during cold nights and cloudy days.  Indirect or Closed-loop – Compared to Direct-gain type, this system do not allow water to go on panels. When the collection of heat in the panels occurs, the heat transfer process lets the fluid flow through a heat exchanger and then transfers the heat to the potable water. The controller in the closed-loop system stops the circulation pumps if the storage tank reaches its maximum temperature.  Drainback System – It drains the water into a storage tank that is contained in a conditioned or semi conditioned place. How to maintain your water heaters The average lifespan of standard heater will last long for eight to twelve years. Moreover, a tankless heater can last two to three times. Therefore, you will need proper maintenance in order to preserve the life of your heater. The life of your tankless heater could last longer than usual up to three times longer if the owner takes care of the heater well.
