Tankless Water Heater

One of the most vital equipment in a home is a water heater. A water heater is a crucial necessity for heating water in a house. Its importance has led to the manufacturing many brands to meet the enormous demand. After checking tankless water heater reviews, you might be interested in knowing the pros and cons of this water heater. This is why we developed this simple guide to help you understand better.

There are different types of water heaters available, each with its own set of advantages and disadvantages. Here are the most common types:

Tankless (On-Demand) Water Heater:

How it Works: Heats water directly without the use of a storage tank. When a hot water tap is turned on, cold water travels through a pipe into the unit, which is heated by a gas burner or electric element.
  • Advantages:
    • Provides hot water on demand, so it doesn't run out.
    • It is more energy-efficient because it doesn't continuously heat water in a tank.
  • Disadvantages:
    • The initial installation cost is higher.
    • It may not be able to handle high demand if multiple hot water fixtures are used simultaneously.

Storage Tank Water Heater:

How it Works: Stores and heats a large amount of water in a tank, maintaining a constant temperature. When hot water is used, it is replaced with cold water that is then heated.
  • Advantages:
    • Lower initial cost compared to tankless.
    • Can supply hot water to multiple fixtures at once.
  • Disadvantages:
    • Limited capacity; can run out of hot water with heavy use.
    • Less energy-efficient due to standby heat loss.

Heat Pump Water Heater:

How it Works: Draws in ambient air and uses a compressor to transfer heat to the water, rather than generating heat directly.
  • Advantages:
    • Very energy-efficient, especially in warm climates.
    • It can also cool the surrounding air.
  • Disadvantages:
    • The initial cost is higher than traditional tank heaters.
    • Performance is affected by ambient temperature; less efficient in colder climates.

Solar Water Heater:

How it Works: Uses energy from the sun to heat water through solar collectors. The heated water is stored in a tank for later use.
  • Advantages:
    • Highly energy-efficient and cost-effective in the long run.
    • Environmentally friendly, as it reduces reliance on fossil fuels.
  • Disadvantages:
    • High initial installation cost.
    • Requires a good amount of sun exposure, which may not be suitable for all regions.

Condensing Water Heater:

How it Works: Extracts additional heat from the exhaust gases, increasing efficiency. It's often used in combination with a storage tank.
  • Advantages:
    • It is very energy-efficient, especially for gas models.
    • Reduces greenhouse gas emissions.
  • Disadvantages:
    • The initial cost can be higher.
    • Installation may require special venting.

Point-of-Use Water Heater:

How it Works: Small, compact units that are installed near the point where hot water is needed (e.g., under a sink). They provide hot water only to a specific fixture.
  • Advantages:
    • Eliminates the need for hot water to travel long distances, reducing wait time.
    • Can be more energy-efficient for certain applications.
  • Disadvantages:
    • Limited to supplying hot water to one fixture at a time.
    • It's important to consider factors like energy efficiency, installation costs, and local climate conditions when choosing a water heater. Additionally, consulting with a professional or a licensed installer can help you select the best type for your specific needs and circumstances.
Tankless water tank is named after the fact that they have no tanks for hot water storage. They are also called on-demand water heaters. The name is credited in that they get water when they a prompted to do so. Tankless water heaters are said to be instant water heaters. Let us now check the pros and cons of tankless water heaters.


Use Less Energy

The Tankless water tanks save on energy. These heaters use very little power. This is because water is heated proportionally. Because they heat water on demand, there is minimal heat loss. Furthermore, it heats the water at the time of need. Hence, they require very little energy to heat the water.

It is efficient to use

How would you feel when you go to shower and find there is no water? It would be embarrassing. Due to the above reasons, that is why you need a Tankless tank. It is efficient to offer water when you need it. Therefore, no shortage, and you also don't need to wait for the tank to get packed.

Save on space and reduce on Storage cost

The Tankless heater is great for saving on spacing. It does not require a storage tank that occupies a lot of space, hence saving space.

Offer a continuous supply of water

A tankless water heater always offers a continuous flow of water. There is no single time you will need hot water. Water is heated as it flows to the shower. If there is water in the tank, you will always have hot water. Thus, a continuous flow of hot water.

Eliminate extra cost

When you buy a water tank, you want to ensure it will not cost you much on maintenance. You want to reduce the additional charges to the least amount possible. With Tankless water tank reduces the additional cost because of:
  • A reduced cost on spares
  • Reduced maintenance cost.
  • There is no storage tank required.
  • Reduced power consumption.


Have no storage space

Just as their name suggests, the Tankless water heaters have no storage for the hot water. This might, at some point, be disadvantageous. Especially when one wants a large amount of water at once.

Have an upfront cost

When we talk about the upfront cost, we consider the cost incurred to make something usable. About this, the heater needs to be a large one because we need a high supply of hot water.

High Initial Cost

Installing the heater is usually very expensive. This is because there are factors that require money that you need to consider. Additionally, the materials used to put the heater into place. This also includes the cost of purchasing the heater.
