    Not a long time ago, you could walk in the market street selling water heaters and the only options you could get were two: gas and electric. Water heaters in every home are crucial as you won’t have to wait for the water to heat up on these old model water heaters.

    With the advancement in technology, the water heater market has greatly changed, and now we have different and several options to choose from.

    As a buyer, you can now even consider tankless and hybrid water heaters. Such freedom and options may make you feel confused and in a deep dilemma when choosing the right and the best water heater. In this buying guide, we bring you all the information you need on water heaters and some of the best models in the market.

    Factors to consider before buying the best water heater

    While owning the best water heater on the market is a good feeling, it is equally important to know what you need to consider before you get your dream shower. Some of the key things to check are as follows. 

    Electric vs. gas

    The only difference between the gas and the electric water heater is the cost. If you prefer a gas water heater, you can pay an average of between $ 1,300 and $2,600, including the installation fee. In comparison, an electric heater will cost you relatively between $950 and $1,500, according to the prevailing rates.

    Although both gas and electricity operating costs keep fluctuating, gas is cheaper than an electric water heater. Gas will cost you around 30 dollars, and electricity will cost you about $42 a month.


    When buying your water heater, it is wise to consider your heater’s ventilation if you intend to buy a gas water heater. Gas water heaters produce carbon monoxide that is harmful to human health hence the need for ventilation. There is no need to worry about ventilation issues with electric water heaters since they require no ventilation and can be installed in any location.

    Size and capacity

    The size of your family or the people you leave with also plays a role in deciding the kind of hot shower you want. The larger the capacity, the more water you can use before the supply runs out and waits for more water to begin.

    If you live in the same building as a family of four people, hot water of between 40 to 50 gallons of water would be perfect water for you. It is also important to consider the water heart’s size and the space available in your home.  Both gas and electric water heaters come with different heights, and this will call for a consideration of the space available before you purchase.


    Different showers come with efficiency as far as energy consumption is concerned.  Efficiency tells the amount of energy used by the water heater.

    For instance, if a water heater has an efficiency of 80%, it means in the amount of energy consumed by the water heater, 80% of it is used in heating water.  But remember, this is not an indication of the amount of money you will pay as the electric bill. In this can, gas will have lower efficiency compared to electrical heaters because they are cheaper. 

    A tankless water heater may cost you less than a heater with tanks since they do not always run to the hot water supply.

    Regarding the water usage in your home, a tankless water heater may save you some coin as it saves up to 40% of the energy bill. We recommend estimating the water heater’s yearly cost to determine one that will not interfere with your overall budget.

    Valve material

    The tank water heater comes with valves most at the bottom used to clean the tanks. They can be connected to a garden hose, and since they are made of either brass or plastic, it is advisable to choose the one made of brass since it’s more durable than the one made of plastic.

    Digital features

    With the current water heaters, they are designed with digital features like a display screen that you can use to perform and program your water heater to perform a different task at a different time, including shutting it when the family is away.

    It may seem an additional cost to the electricity bill, but it is worth noting that it improves the water heater’s efficiency.


    You would not like it when you have just bought your water pump, and within no time, you find it not functioning. That’s the last thing you would ever wish to happen, even to your worst enemies. So it is wise to consider how durable the water heater you intend to buy lasts.

    This way, you will cross-examine different water heaters and probably land on a durable and long-lasting product.

    Working with the right plumber

    When buying, installing the same water heater will have a big role in the latter’s performance. Not all the plumbers will have experience in the installation of every other water heater. Consult with your plumber and get to know whether he is familiar with installing the water heart.

    Poor installation of the water heater is the leading problem associated with the performance of the water heaters.

    Consider water heaters with a warranty.

    Normally, water heaters come with a warranty between three to twelve years. Although you may pay more for the products with a lengthy warranty, it is an indication that the product is of high quality and the manufacturer trusts that the chances of performing beyond the warranty are very high.

    They are mostly made with elements that can heat water faster with thicker insulation to prevent heat loss. For this reason, choose a water heater with a longer warranty.

    Types of water heaters

    When that time comes to choose a water heater for yourself or the whole family, you would wish you had the right and most performing water heater. That’s not possible until you familiarize yourself with the types of water heaters available in the market. The following are the types of water heater you need to know before you embark on buying.

    Conventional water heaters

    storage tank water heater

    Conventional water hearts are also referred to as the storage tank water heaters and are the common types. Conventional water heaters are installed with a storage tank used to store heated water until they need to be used.

    A natural water heater can be expensive and difficult to install. Still, it is worthy to note they are cheaper to operate than electric water heaters because they use less energy.  With conventional water heaters, you will require regular maintenance to operate efficiently and effectively.

    Again, conventional water heaters must be drained at least once every year to remove residues and sediment, and build up that may cause clogging. The conventional water heaters’ life expectancy is estimated to be between 10-12 years but with the right and consistent maintenance.

    Tankless water heaters

    Tankless water heaters are water heaters that intensely flash heat against water-filled coils to heat water on demand. They are more energy-efficient than conventional water heaters but come with a high upfront payment. Tankless water heaters can serve bigger families that use a lot of water once as they continuously provide hot water.

    One downside with tankless water heaters, if you prefer to use them with natural gas, the installation may require a larger diameter gas line, which is potentially expensive to purchase.

    You may require upgrading your home’s electricity capacity with the electric water heaters if it is insufficient. Like the conventional water heater, tankless water heaters require to be descaled of minerals and other sediments at least once a year to keep them functional and reliable.

    Heat pump water heaters

    Heat pump water heaters, also known as hybrid electric water heaters, work through a mechanism whereby they capture heat from the air or the ground and transfer it to the water; they relatively cost more upfront payment but uses at least 60% less energy, making them energy efficient while making owners realize a return in their investment in the form of energy bills.

    However, for the people living in cold space, a heat pump water heater may not work for them because the heat pump is placed on top of the appliance and the hybrid unit requires as much as 7 feet clearance from the floor to ceiling.

    Solar water heaters

    Solar water heaters work through solar panels installed on the roof of the building that absorbs solar heat and transfers it to the eater enclosed in a loop system that runs to the water tank and heats the water.

    They are water heaters that can save you huge money during summer as far as electricity bills are concerned, making them ideal for the warm and hot regions. Consider talking or consulting an expert for advice accordingly on the right solar panel depending on the family size and the energy usage expectations.

    Condensing water heaters

    Condensing water heaters are water heaters with tanks like the conventional water heaters that capture hot exhauster gas normally expelled from home.

    The gas expelled is directed through a coil on the water heater base, where the incoming cold water is heated. Condensing water heaters are highly efficient water heaters for homes that use gas and require a large capacity of more than 55 gallons of water.
