The Pros of a Tankless Option

Our comparison of tankless water heaters vs. solar water heater starts with the tankless unit. It works by using water directly. The advantages are very significant and beneficial for anyone. They are as follows:

  • It heats it in about 5-10 seconds only.

  • The ability to get hot water on demand without waste of time.
  • It has a compact design and will never take up a lot of space in your house.
  • It is more affordable than a solar system.

The Cons of a Tankless Option

Now, we should check the cost of our solar hot water heater vs. tankless comparison. The main con is the cost of the installation of this device. It is pretty expensive itself. Moreover, the cost increases if your house is old and has an old system of pipes. They must be adjusted to the new device that does not fit them at all. In case your house is new, it surely suits any modern tankless water heater.

The second drawback is the water capacity of this device. When several people use it at the same time, it may not be able to supply everyone. Someone will have to wait a bit longer to get the water heated to the desired temperature. In the meanwhile, this process will take just about 30-60 seconds. Therefore, it’s not that long, and this drawback is not decisive. After all, this issue can be solved if the power of your device is more considerable.

The Pros of a Solar Analog

The comparison of tankless water heater electric vs. solar heater continues by mentioning the main benefits of using the solar analog. The solar device heats water by storing it in a specific collector. It has great benefits as well and can suit your household under certain conditions. Make allowances for its strong sides:

  • An incredibly cost-efficient because it uses the sun as fuel.
  • Can work with a current water heater you already have.
  • It is adaptable and efficient.
  • Saves a lot of money on monthly and yearly billings for electricity. It can save up to 50%-80%.

As you can see, these advantages are very profitable for anyone.

Sometimes, the choice of a solar unit isn’t reasonable for householders. Our tankless water heater vs. solar water heating comparison surely highlights these obstacles as well. Let’s review them here below:

  • Its upfront cost is very expensive.

Nonetheless, this con may turn into a pro in the long run. If you count all the money you will spend on energy in some 5-10 years by using solar and tankless units, the solar type is surely more profitable for you.

Both options have their pros and cons. The tankless unit costs less, suits large households, and can be used anywhere. Its installation costs are pretty pricey.

The upfront cost of a solar analog is much higher. However, this con disappears in several years. It helps to save up a lot of money – 50-80%. It makes little use in regions with a cold climate because clouds and snow commonly hide the sun.
