2018 Buyers Guide to the Best Electric Tankless Water Heater
Washing dishes require warm water to ensure grime can be effectively removed and bacteria can be destroyed. You use warm water for food to ensure the water can boil faster, resulting in less cooking time. Buying an electric tankless water heater will give you instant access to unlimited warm water in your kitchen, laundry room and bathroom. There is no need to worry about having to maintain a full tank, and you get the benefit of lowering your power consumption. Before you make a final decision, there are some elements that need to be taken into account to ensure you buy the most appropriate device for your requirements.
3 Main Points to Consider:
- Size of the heater: The size of the electric tankless water heater that you buy will play a role in determining whether it will be easy to install. Buying a device that is larger than space you currently have, means you will have to make certain adjustments. Adjusting for space can be unpleasant and even lead to additional costs – since you are trying to save money with an electric tankless water heater, you want to keep the initial installation costs as low as possible. We recommend first considering where you want to install the heater and consider the space you have available for the device, and then to start looking for a device that will fit into this space. Electric tankless water heaters vary widely in size, so there is sure to be one that fits into the space you have available.
- Maintenance required by the heater: Lower maintenance requirements equal fewer expenses for ensuring an electric tankless water heater can continue operating without any problems. While older models of these devices tend to build up substances within the device, such as limescale, newer models on the market tend to utilize special technology that helps to reduce the buildup of limescale within the system. In turn, this means you will not need to spend as much money on the maintenance of the electric tankless water heater as compared to an option that will constantly cause limescale to build up in the pipes. Heaters fitted with infrared technology is one example of how limescale buildups can be reduced, and maintenance costs can be lowered significantly. Even though these models may cost somewhat more than an older heater, they will provide you with better value for your money in the long run.
- Configurations offered by the heater: Some electric tankless water heater will come with a single default setting build into the device, while others will allow for the configuration of the system. It is essential to consider this option as opting for a device with only one single setting might be unpleasant when the water becomes too hot or when you find that the water that comes from the device is not hot enough. A device that offers you the ability to configure the particular settings, including the temperature that water should be heated to, will ensure you get access to water that is just the right temperature – not too hot and not too cold. This can be very useful when washing dishes and even when cooking, as warm water is something that we constantly use in the kitchen, but we may sometimes require different temperatures of warm water to suit the particular activities they will be used in.
What makes electric tankless water heaters more energy efficient?
One of the primary reasons why so many people are starting to switch from traditional tank heaters to tankless water heaters is due to the energy efficiency offered by these devices. When it comes to the time spent in the kitchen, there are different ways in which the installation of an electric tankless water heater can help you save money on your utility bills. Firstly, these devices only consume power when they are put into action – this means that, when the tap is not open, the device will be switched off. Since there is no tank full of water that needs to be kept warm throughout the day, it means much lower utility bills since a tank heater will continuously consume power. Additionally, also think about the time you will save during cooking – and, of course, on your electric bill at the same time. When you start off with warm water, your food can get cooked faster – this means your stove will be on for a shorter period of time.
