What is a Tankless Water Heater?

A tankless water heater is a great choice for anyone looking to save space and money on their utility bills. These units heat water on demand, so you only pay for the hot water you use – no wasted energy keeping a tank of hot water heated and ready to go.

How does a Tankless Water Heater Work?

If you are considering purchasing a top tankless water heater in Malaysia, it is important to know what the top options are. Tankless water heaters are becoming increasingly popular due to their energy efficiency and space-saving design. 

A tankless water heater is a very efficient way to heat water on demand. They use a gas burner or an electric element to heat water as it flows through a heat exchanger. This means that there is no need to store hot water in a tank, so they are more energy-efficient than traditional storage water heaters.

Tankless water heaters are becoming increasingly popular in new homes and renovations because of their space-saving design and energy efficiency. If you are considering installing a tankless water heater, here is how they work:

1. Cold water enters the unit through a pipe connected to the main water supply.

2. An internal gas burner or an electric element heats the water as it passes through the heat exchanger.

3. The now hot water exits the unit through another pipe to be used for showers, dishes, laundry, etc.

Advantages of Tankless Water Heaters

If you’re considering a tankless water heater, you may be wondering what the advantages are compared to a traditional storage-tank water heater. There are several key benefits that make tankless water heaters a great choice for many homeowners.

Perhaps the most obvious advantage of a tankless water heater is that it takes up far less space than a storage tank model. Tankless water heaters are compact and can be hung on a wall, which frees up valuable floor space in your home.

Another big advantage is that tankless water heaters provide an endless supply of hot water. With a traditional storage tank heater, you’re limited to the amount of hot water stored in the tank. Once that’s gone, you have to wait for the unit to heat more water before you can use it again. This isn’t an issue with a tankless model since it heats water on demand as you need it.

Tankless water heaters also tend to be more energy-efficient than their storage tank counterparts since there’s no need to continuously heat and reheat stored gallons of hot water. This can lead to significant savings on your energy bills over time.

Disadvantages of Tankless Water Heaters

If you’re considering a tankless water heater, there are a few disadvantages to be aware of. One is that they require more maintenance than traditional tank heaters. You’ll need to descale your tankless water heater every few months to prevent mineral buildup, which can lead to corrosion and decreased efficiency.

Another disadvantage of tankless water heaters is that they have a higher initial cost than traditional tank heaters. They also require special venting and gas lines, which can add to the installation cost.

Finally, tankless water heaters have a limited flow rate. This means that if you have a high demand for hot water (for instance, if you have a large family or frequently entertain guests), a tankless water heater may need to be able to keep up.
