Benefits of Buying An Electric Tankless Water Heater

There are many benefits of an electric tankless water heater which makes them useful.

First and foremost, electric water heaters are generally more affordable, especially when it comes to the upfront cost of the unit.

Secondly, electric water heaters are more efficient than other types of water heaters. With gas water heaters, the majority of energy loss occurs as a result of the venting process. Of course, this is not the case in electric water heaters and energy is better retained ensuring optimum savings.

Thirdly, electrical units do not experience leaks like gas units do. This means they can be placed inside the house without any worry of posing a safety risk. Typically gas units require additional piping or housing to be added, making installation slightly more complicated too.

Lastly, tankless electrical units work instantly on demand, which means you never have to wait for hot water. Also, they don’t have storage tanks, making them a big space saver.

Atmor Water Heater Features

Let’s take a closer look at the main features of this electric tankless water heating appliance.

We briefly touch on two of the smaller ThermoPro units further down in this post too, so that you can choose the appropriate size to suit your hot water requirements and climate.

Advanced Digital Control Panel

This model features an extremely easy to use digital control panel, allowing you to have absolute control over the temperature of your water around your home. This allows you full flexibility as to how hot the water is coming out of your faucets, and requires little to no effort to change.

Compact and Space-Saving Design

What really makes the Atmor water heater ideal for your home or apartment, is that it does not require any venting like gas heaters do. The sleek, space-saving design gives you ultimate flexibility as you can install it anywhere inside your home or garage.

Furthermore, because it is tankless, it takes up even less space in your home. A tank appliance stores and heats water within the unit, and therefore requires a bit more space for installation.

Safe To Use

Atmor has received an IP54 certification for this unit. The certification guarantees that internal components are kept safe and dry inside the water heater. Naturally, this is important to consider when dealing with electrical components and water.

Self-Modulating Technology

A great feature of this Atmor water heater is the self-modulating technology it uses. The unit automatically activates when it senses water flow, and then shuts off when the water flow stops. This means that there is less energy wasted, unlike what you see in tank appliances. That is because tanks continuously use electricity to keep the water heated to a specific temperature so that it is ready to use at all times.

Improved Energy and Water Efficiency

As we saw above, this Atmor only activates when it senses water flow. This means that it only uses energy when it is being used and is not constantly running. It is therefore incredibly energy efficient and will save on your household energy bills.

Ideal For Use In Various Climates

As previously mentioned, this Atmor 27kW/240V water heater unit can function in a variety of climates.

In warmer climates, you will be able to run up to five applications simultaneously, ensuring your family has access to hot water at all times. This could include two showers at 1.5GPM, a kitchen sink at 1GPM, and two bathroom sinks at 0.5GPM.

This is reduced to three applications in colder climates. For example, you could use a showerhead at 1.5 GPM and a kitchen sink at 1GPM without jeopardizing the heat of the water or facing the chance of running out.

What We Like

• Easy operation and low maintenance
• Space-saving and compact design
• Easy, wall-mounted installation
• Digital settings ensure optimum functionality and give you full control over the exact temperature
• Safe and efficient
• Good value for the price
• Works well for the entire house
• Self-modulating system offers increased energy efficiency and savings
• Long term 2-year manufacturer’s warranty and a 7-year warranty against leakage

Minor Drawbacks

• Pressure relief valve not included
• Does not reach full efficiency in colder climates due to lower inlet temperature
