Since 2003, for the first time a widespread change to water heaters is being introduced. This is good news for homeowners looking to get more energy efficient appliances. The transition to more efficient units will heat water at a lower cost to the homeowners. But, when are going to replace your electric heater, you should know the basics of this home appliance as well as its’ working system.
Different types of Water Heater
Generally, the water heaters used for residential purposes are found in four different types.
The tank-type water heaters are most demanding kind of water heaters.
The tank-less water heaters are rising immensely with time.
The hybrid models of water heaters are comparatively new, but to get maximum amount of energy, you may consider this type.
The point-of-use water heaters are designed for supplying warm water speedily to the faucets. Pieces of this equipment are positioned far-off from the primary water heater.
Now, understand the working system of the different types of Water Heaters briefly:
Tank-Type Water Heaters
Traditional Tank-Type Water Heaters are found in most of the homes. Either gas or electricity provides power to these water heaters. Electric Water Heaters are cheaper than the Gas Water heaters. It is true that electricity is more costly than gas.
But the gas hot water heaters are not so effective as the electric models. The factor of energy ratings of electricity is higher than gas. Following its name, a heater tank-type with large insulated storage space tank which hold hot water till it’s essential.
Here is how it works: At first, the cold water gets into the tank. Then it is warmed by either a gas-flame under the water tank or an electrical basics into the water tank. An adaptable thermostat control and maintain the temperature water. A pressure-relief valve helps to prevent an excessive pressure that build-up into the tank.
When you require hot water through a faucet or a home appliance, the warmed water is released out from the top of the tank, and then it comes through the pipelines of the hot water of the home.
When the water level decreases into the tank, it is automatedly get replenished with cold water, and the total process restarts.
Tank-less Water Heaters
The tank-less water heaters are wall hung vanity unit and compact which offer hot water not only for one faucet but for the whole house. These are often called on-demand or instantaneous water heaters. And, this kind of water heater has no huge storage space.
Know how works this Tank-less Water Heaters:
A tank-less water heater starts to work after opening the hot water tap of the house. After that, chill water is drawn in the unit. Then a sensor for flowing activates the elements of electric heating or a burner powered by gas. As result, an Internal Heat Exchanger gets warm. As chilled water passes over the Heat Exchanger it gets hot the pre-fixed temperature. Then warm water pushes out that heater; then flows straight to the appliance or faucet, but not to the Storage Tank. Ignition gases, generated by the gas-fired units, are worn out through an enthusiastic, sealed vent pipe.
When the tap of the hot-water is switched off, then the heater is terminated in operation. And here is the key benefit of using the Tank-less Water Heaters. When there is no Storage-tank for filling water, the tank-less models are the only option for heating water following your necessity. Consequently, a Tank-less Water Heater supplying 40 gallons of warm water every day using less than 34% energy of a typical water heater.
And if you require maximum energy effectiveness, consider a concentrated Tank-less Water Heater that work with an effectiveness rating from 90% to 98%.
As there is no storage-space inside the tank, the Tank-less Water Heaters offer unlimited warm water supply, and it is very much useful for the big families. The longevity of a tank-less heater is near about twenty years, which is almost twice of a Standard Tank-type Water Heater. The downside of the Tank-free water heater is that it is more costly for purchasing and installing it than a slim-type water heater and its repairing cost is also high enough.
Hybrid Water Heaters
A hybrid water heater is a tank-type heater that’s equipped with an electric heat pump. The pump is mounted on top of the water-storage tank and it uses a compact compressor and evaporator coil to capture heat from the room air and then transfer it to the incoming cold water. As a result, a hybrid model uses 60% less energy than a conventional water heater.
Point-of-Use Water Heaters
The Point-of-use Water Heaters are also compacted like a Whole-House Water Heater. The Tank-free models give out warm water nearly right away to a particular location, for instance, a sink or shower of a bathroom.
This kind of Electric Heater is frequently fitted at fixtures situated at a distant of core water heater. Its key characteristic of selling is that it removes the normal issues of starting a tap and waiting for warm water. This type of awkwardness not only wasting of time and massive amount of energy and water also.
