Many people do not stop to wonder where all their hot water comes from. It is easy to take a hot water supply for granted until you wake up one morning and you cannot get hot water. The water heating system is one of the most important appliances around the house. There are many types of hot water heaters. It is important to understand these different types, especially if you are planning to replace your old water heater. Here are the types of water heaters you’ll find in the market today.
1. Storage Tank/Conventional Style Water Heaters
This is the most common type of water heater. It is powered by electricity, fuel oil, natural gas, or propane. These heaters can hold up to 80 gallons of water but you can get a smaller size that holds just 20 gallons. In this type of system, the water is heated and stored in the insulated water tank. As hot water is released from the top of the tank, cold water accesses the tank from the bottom to be heated and replace the used water. It gives your home a ready supply of hot water and is affordable. One downside is that a lot of energy is lost during standby and it only lasts for about 10 years.
2. Tankless Water Heaters
Tankless water heaters provide hot water on demand. For this reason, they have zero standby energy loss. They are powered by electricity, propane, or natural gas. Cold water runs through a heating element where it is heated instantly. This heater improves heat efficiency by up to 50% more than storage water heaters and guarantees availability of hot water at all times. However, they are a bit expensive to install and the flow rate can limit the supply of hot water.
3. Heat Pump Heaters
Heat pump heaters can also be used to heat or cool the home. They are powered by geothermal energy or electricity. This heater works the same way as a tank water heater even though the first-hour ratings may vary. This heater works by pulling heat from the environment and drawing it into heat water. It works like a refrigerator but as a heating system instead of a cooling system. It is more energy efficient than the tank water heater, it’s cheaper to run, and is easy to maintain. However, it can only work in areas with temperatures of 40 to 50 degrees. It is expensive to install and purchase.
4. Solar Heaters
These make use of solar energy to heat water. They come with collector plates that absorb the heat of the sun which is then used to heat water stored in a tank. Because it uses renewable energy, it is highly efficient and has a low running cost. Even so, it will almost always require a backup water heating system.
5. Indirect or Tankless Coil Heaters
This is one of the not-so-popular types of water heaters. They use of your home’s heating and cooling system to heat water. The tankless coil heater will produce water on demand while the indirect heater uses a storage unit. They both need a boiler or furnace to work. They are most effective when used in an integrated home heating system. They are less expensive this way. Even so, these systems can be inefficient for people living in warm climates.
