Hot water heaters are one of the most common appliances found in every household. In the US, an average household spends about $400-$600 every year on water heating. It is the second largest expense that accounts for 14% to 18% of a household’s utility bill. This suggests that investing in energy efficient hot water heaters is the need of the hour. It will not only help save you some money but also conserve energy.
Here, we have compiled a list of different types of hot water heaters that you should be aware of before buying the one right for you.
Storage water heater
This type of water lasts for 10-15 years. In this, the heater holds a pool of hot water and releases it from the top of the reservoir whenever the hot water tap is turned on. Once the hot water is released, cold water fills the bottom of the reservoir. These are inexpensive and easily available.
Tankless water heater
These heaters provide hot water only when needed and eliminate any standby heat loss. Tank-less water heaters last for around 20 years and are up to 34% more efficient than storage water heaters. Also, Energy Star qualified tank-less water heaters may help you save $100 annually.
Solar water heater
There are several types of solar water heaters but the two most common types are active and passive. Active types have circulating pumps and controls while passive types do not have any. Solar water heaters are 50% more efficient than electric or gas heaters. Although its initial cost may be a little higher than the normal hot water heaters, it makes use of sunshine as fuel which is a free and renewable resource. However, these heaters may require a back up during cloudy days.
Tankless coil heater
This type of a heater does not have a tank and provides hot water on demand. The water gets heated as it flows through a heat exchanger or a heating coil(installed in the furnace) when the hot water faucet is turned on. This usually lasts about 10 years. Tank-less coil heaters are highly efficient during colder months when heating is often a major requirement.
Heat pump heater
This heater does not generate heat directly; instead, it uses electricity to allow heat to move from one point to another like in a refrigerator in reverse. ENERGY STAR qualified heat pump heaters can help save around $300 on your electric bills annually. These heaters can last between 10-15 years. However, there are a few limitations to this type of hot water heaters and you will have to consult a specialist.
