Water Heater Tank and Tankless: Which One Suits Your Needs?
With our busy lives, we often tend to overlook the importance of hot water until we run out of it. Having a reliable and efficient water heater is crucial for every household. If you are currently in the market for a water heater, you may have come across the two common types: the water heater tank and the tankless water heater. In this blog post, we will discuss the differences and advantages between the two and determine which one suits your needs.
How They Work
A water heater tank stores and heats a pre-determined amount of water, typically ranging from 20 to 100 gallons. Once this hot water is used, the tank refills and reheats the water to maintain the set temperature. A tankless water heater, on the other hand, heats water on demand. As soon as a hot water tap is turned on, cold water flows through the heating element and gets heated instantly. This means that a tankless water heater does not store hot water, and eliminates the need for a tank altogether.
Energy Efficiency
Because a water heater tank needs to maintain the set temperature of the stored water, it is constantly using energy even when not in use. This leads to standby heat loss, which is a significant waste of energy. In contrast, a tankless water heater only uses energy when hot water is needed. This results in minimal energy loss and more significant energy savings in the long run.
Installation and Maintenance
Water heater tanks are generally easier and more affordable to install because they are a common and widely-used option. Maintenance is usually just flushing sediment from the tank and checking the anode rod. Tankless water heaters may be more challenging to install, take up a bit more space, and usually require professional installation. However, maintenance is more straightforward as there is no tank to flush or sacrifice anode rod to replace.
Capacity and Demand
Water heater tanks come in different sizes, ranging from small households to larger families. The capacity of the tank determines the amount of hot water available, and this can limit the amount of hot water available during peak demand times. A tankless water heater’s capacity depends on the flow rate of hot water demanded. Although they can be limited by the number of hot water tasks running simultaneously, they deliver endless hot water and prompt recovery.
Cost
Water heater tanks are generally more affordable than tankless water heaters upfront. They also have a longer lifespan, typically lasting between 10 and 15 years. However, energy efficiency and standby heat loss make water tanks more expensive in the long run. Meanwhile, tankless water heaters have a higher upfront cost yet offer more energy savings. They also have a shorter lifespan of around 20 years, and maintenance is typically less expensive.
When deciding between a water heater tank and a tankless water heater, ultimately, your decision should depend on your household’s specific needs. If you have a small household with minimal hot water demands and have limited space and budget, you may wish to opt for a water heater tank. Suppose you are looking for energy efficiency, endless hot water, and minimal maintenance costs. In that case, a tankless water heater is a smarter investment. Remember to consider how much hot water you need, how much energy you want to save and how much you can afford to spend upfront. With this guide, we’re hoping that you can make an informed choice and choose the best option for your household.
