Planning to repair the water heater for your house? In most likely cases, a tank-type hot water tank and tankless water heaters will be your preferred choices. We will help you select the best one out of these two options.


Hot Water Tank

Tankless Water Heater


Hot water tanks come in a variety of capacities and sizes ranging from 20 gallons to 120 gallons and above.

As tankless water heaters don’t store water in them, they don’t have any specific capacity. However, they can heat a limitless amount of water continuously.


A hot water tank will take a long time to heat the entire quantity of water that’s stored inside the tank at a point. Depending on the capacity of your heater, it will take at least five minutes to get hot water.

You don’t have to wait for minutes before getting hot water. All you have to do is switch it on, wait for a few seconds, and you will get hot water instantly.


They are classified based on the energy they utilise. Gas, electric, and solar water tanks are the three most common types.

You will find tankless water heaters in gas, electric, or hybrid variants.

Availability of Hot Water

When you rely on your hot water tank, you can get a limited amount of hot water. This quantity depends on the capacity of your tank. If you have a 50-gallon hot water tank, you will only get 50 gallons (or less) of water at a time. If you need more hot water, you will have to wait for a few minutes for the new water to get heated.

There’s a reason why these water heaters are called “on-demand” water heaters. You switch the heater on, and you will get hot water till the time you want it. You switch it off, and it will stop giving hot water. This means that you’ll always have hot water without having to wait much.

Energy Consumption

Hot water tanks consume a lot of energy. You have to keep the power on till the entire volume of water inside the tank is heated. Even if you need one bucket of water, you will have to keep the power on.

When it comes to energy consumption, a tankless water heater is considered to be the right choice as it uses electricity only for a limited time when it has to heat water. You can switch the heater off once you are done with your bath.

Although tankless water heaters save money in the long run, they cost a little more than hot water tank heaters due to the high-efficiency elements which eventually help you save up on energy costs. Apart from these differences, you must also know that tankless water heaters survive longer when compared to tank-type heaters.
