Tank or Tankless Water Heater

Tank vs. Tankless Water Heaters

When looking for a new water heater, you may be asking yourself if you should get the standard tank heater or go for a new tankless water heater. The answer is not a simple choice. Which water heater you chose depends on several factors, each dependent on your specific needs.


Most homes come with a standard tank water heater. These heaters are the cheapest option, when it comes to choosing a hot water heater. If having enough money upfront is a concern, tank water heaters are the best choice. Tank water heaters also offer extra water storage, in case of emergency or natural disaster. The water already stored in the heater can be used for many purposes, including drinking, when needed. In the case of a power outage, you will still be able to get hot water, as the water is already heated, ready for you to use, without the need of electricity to heat it up on the spot. The biggest drawback of tank water heaters is when the hot water on reserve runs out and you have to wait for the heater to heat up more water. You also run the risk of flooding, if the heater ever gets a leak.


Tankless water heaters are more energy efficient than the traditional tank heaters. They can save you quite a bit of money on your utility bills. They also offer instant hot water. No more waiting for hot water to heat up, the hot water is available on demand, when needed. The biggest drawback of the tankless water heater is the cost. They are very expensive to buy and get installed, when compared to a traditional tank water heater. The equipment is more expensive and the installation is much more complicated, causing the overall cost to be high. You will save money on utility bills in the long run, but having the initial upfront investment is difficult for many homeowners.


Whether you decide on a traditional tank water heater or a tankless heater, your local plumbing company can help you assess your needs and make the right decision for your home. They can then help you install your new water heater, and get your hot water running again quickly and done right the first time.
