Water heaters have become essential household equipment. Several household chores and conveniences like washing clothes and dishes or having a hot shower need hot water supplied by the water heater. It could be the first time that you are installing a water heater or replacing the old one.
When installing a new water heater, you should first determine the capacity and energy consumption of the equipment. Also, you must know the volume of hot water required every day. It means that you have to consider the number of users in the family. Besides, you must have an idea about how much energy charges you are ready to bear. In case you are replacing the water heater, you must already have the data readily available. However, for both scenarios, you must know the different kinds of water heaters so that you get just what you want. After gathering information from the market, look at the water heater review of each type to understand about its performance and maintenance aspects. From storage water heaters to tankless water heaters and from electric heat pump water heater to solar water heater, you will know about your options in this article.
Storage water heater
The most common type of water heater consists of an insulated tank that stores hot water. It comes in different capacities varying from 30 gallons to 80 gallons. The heating system depends on the utility services available, and it can be anything like natural gas, oil, liquid propane, and electricity. The system uses a thermostat attached to the tank set at a given temperature. When the temperature exceeds the limit, the energy source is automatically cut off thereby preventing any possibilities of overheating. Again, when the temperature falls below a certain preset level, the heating system becomes operational. The cycle of heating the water in the tank continues round the clock and throughout the year.
Half yearly cleaning of the tank is recommended to avoid deposition of sediment that can affect the performance. Besides, testing of the pressure relief valve is necessary to ensure its smooth functioning. Switch off the heating source when working on the water heater.
Tankless water heaters
As the name suggests, this type of water heater does not use any tank for storing water. Such types of equipment use the technology of instant heating and are also known as an instantaneous water heater. The water starts heating when you switch it on and is available for ready use. You get hot water as long as you keep the equipment switched on. The moment you switch it off, no more hot water will be available. Since heating is done when you need hot water, the system uses less energy as heating stored water does not require anything. These water heaters can supply only 2 to 5 gallons of hot water per minute, and you can only accomplish one household task at a time.
If you want to use hot water at multiple points, you have to install a compact design water heater consisting of various units catering to a different set of appliances. The average lifespan of tankless water heaters is about 20 years. Periodical flushing of the unit is recommended to avoid sedimentation inside the equipment.
Electric pump water heaters
Electric pump water heaters are storage type water heaters, but the method of heating is different. This type of water heaters uses electricity as the source of energy as it draws heat from the environment first and then heats it up further for heating water in a tank. Since the technology uses heat available from the environment, the equipment works best in hot climates. With the proper environmental support, the machine can be three times more energy efficient than other types of water heaters.
The maintenance aspect of the water heaters is same as the storage water heaters expect that you have to clean the air filters periodically.
Solar water heaters
The solar water heater uses solar energy to generate the heat required for heating water. Although some might believe that it does not work well in all types of climate, the reality is just the opposite. The unit comprises an insulated tank and a solar collector and installing the equipment on the roof or in the yard is the standard practice. Active solar heaters use a pump to distribute water at different points while the passive solar heaters use the gravitational force. Active solar heaters can deploy direct or indirect circulation system for heating water. Passive solar heaters are less expensive and are available as integral collector storage system and thermosyphon system. You would need a solar water heater specialist to maintain the system.
Consider the facilities at your home for proper installation to decide what would be good for you.
