Buying Guide
The choice of the best electric tankless water heater will depend on your individual needs and circumstances.
Benefits of using a tankless water heater
- These units can save energy use for heating water by up to 34% for an average family every day. This is because these units do not store hot water in the unit but instead heats the hot water as it is being used. This helps save the energy that would have been used to maintain the water temperature were it to be stored in the unit.
- A tankless water heater provides an endless and consistent supply of hot water when and wherever required. You won't have to wait for the water to heat up or for the tank to refill because these units feature coils and elements that heat the water instantaneously providing the hot water at any point of use.
- Tankless water heaters are available in a variety of models which makes them efficient in serving individual needs. There are small models for point-of-use installation and larger models that can save the whole house. Their availability in different sizes and varieties makes them not only efficient for specific hot water needs but also they help avoid energy wastage as they heat only the water that needs to be used at any particular time.
- They are reliable and long lasting: As opposed to traditional water heaters with a tank, water with minerals that may corrode the unit does not sit in the unit because it just moves through. This makes them highly reliable and durable as they easily outlast tank models by over ten years. You will be able to save a lot on replacement costs also.
- You can easily replace parts with tankless water heater models. Most other units will require a complete overhaul of the system which can be quite costly and time-consuming.
Water flow for tankless water heaters
When you are in the market for a tankless water heater, you should reconcile your hot water needs with the flow capacity of the unit you intend to buy.
This is because although all tankless water heaters supply endless hot water, the hot water isn’t stored anywhere but is heated directly as it runs through the unit.
As such, if you intend to use your tankless water heater to supply hot water to more than two points that are being used simultaneously, then you will need to look for a unit with powerful heating elements otherwise you may end up with lukewarm water if you go for a smaller unit.
Furthermore, you may need to stagger usage of the hot water if your needs require a lot of hot water. This is especially so if your faucet at the point of use has a heavy flow or you are using more than one point at a time.
This will help avoid the issue of getting lukewarm water when you need hot water. The issue of choosing the right size of unit for your hot water needs is a big factor here when you need a reliable and consistent supply of hot water.
Types of tankless water heaters
Basically, there are two types of tankless water heaters; electric and gas powered units.
The gas-powered models are much faster and more efficient in heating and providing a continuous supply of hot water. This makes them ideal for whole-house hot water use because of the heat output and faster response time required.
However, these units will require venting and are generally larger and costly than the electric models.
Electric models, on the other hand, are much smaller and with varied designs and construction. They do not require any venting and are much simpler to install and use. Some models will feature a plug-in design while others have to be hardwired; especially the larger electric models.
They are quite efficient and faster although they cannot match the gas models when large quantities of hot water are needed at ago.
Factors to consider when choosing an electric tankless water heater
Flow rate
Because tankless water heaters do not store hot water, their rated flow rate determines the capacity of hot water they can provide at a time.
Bigger flow rates usually mean they can provide more hot water and can be used for multiple points of use while smaller models with small flow rates are ideal for installation as point-of-use units.
Space
The point of installation for this unit determines the type of unit you choose. There are tall units that are ideal for installation anywhere where space is not a limiting factor while the smaller short units can be installed in constrained spaces and still provide the same effective service.
Dry fire protection
This feature helps prevent the upper element of the unit from burning out when the unit detects no water around it.
Energy Efficiency
As with any other electric appliance, high energy efficient tankless water heaters are not only good for the environment but will also save you money as the operating costs for highly energy efficient models are considerably low.
Intuitive technology
This includes features such as Wi-Fi capability and features that allow other operating features such as temperature to adjust accordingly depending on your needs and use patterns.
These features offer better energy efficiency, improved performance and better durability for these units.
