Best Electric Water Heater Buying Guide
As you are sure to have noticed, not all electric water heaters are created equally. They can vary widely in terms of efficiency, capacity, and a number of other factors. If you are searching for the best electric water heater around, here are some of the key factors to look for.
The Energy Efficiency
It goes without saying that this type of heater will use electricity to heat the water. However, the amount of energy that different models consume can vary widely. Unless you want your energy bills to sore, it is a good idea to choose a model that is as energy efficient as possible.
Models that are especially energy efficient only heat the water when it is actually needed. This prevents wasting energy by keeping the water permanently warm. Therefore, it is a good idea to make sure that the model heats the water quickly.
Hot Water Capacity
The amount of hot water that you require will depend on your specific needs and usage. If you have a large family, make sure that the model you choose has the capacity to suit. A best electric water heater that boasts a 40 or 50 gallon capacity is sure to be sufficient to serve the whole family.
The Flow Rate
In order to provide hot water, some heaters significantly reduce the water flow rate. This can be rather frustrating if you are taking a shower, and water starts to dribble out. Therefore, check the flow rate of the model you have set your sights on carefully.
The flow rate of different electric water heater brands is indicated by gallons per minute. Naturally, the higher the number, the better the flow rate is going to be. A flow rate of five gallons per minute (GPM) is likely to be sufficient, even for large households.
A water heater that displays the temperature on the front is sure to be especially useful. This will allow you to see what temperature the water is at a single glance. Ideally, the display should feature numbers that are easy to read from across the room.
If you do need to change the temperature of the water, it should be a smooth and easy process. There should either be a dial or buttons on the front of the unit. This will allow you to turn up or down the temperature very quickly and conveniently.
Some water heaters take up considerably more room than others. Before making a purchase, take the time to work out where you will install the heater. It is essential to make sure that you have enough space for the model you have set your sights on.
There are certain elements that reflect how durable your new best electric water heater is likely to be. The model should be set with an aluminum anode rod to protect the water heater from corrosion. Take a close look at the materials your water heater is made of and the overall build quality.
Going the Distance
The warranty that is supplied with the electric water heater is a good indication of how long it will last. It is important to check the details of the warranty carefully before making a purchase. Some warranties only include certain parts, while others cover the whole electric water heater.
It will be a real bonus if the model you choose comes complete with a lifetime warranty. This means that you can be sure the heater will be with you for the rest of your life. If anything goes wrong at any time, the company will fix or replace it free of charge.
Installation and Maintenance
Last but not least, spare a thought for the overall installation process. Some models tend to be much easier to install than others. If you are planning to complete the installation process alone, make sure you are provided with everything you need.
It will be an added bonus if the instructions that come with the water heater are very clear and detailed. A step by step guide is likely to be the easiest to follow. The process should be very quick so that if all else fails, you can contact a professional to complete the job.
It is also important to note that some electric water heaters require quite a bit of maintenance. If you have a busy schedule, you might find that constantly maintaining your water heater is a real chore. Therefore, you might prefer to choose a model that requires little or no maintenance.
Not sure if electric is the best choice for your water heating needs? Probably not, or you wouldn’t have got this far. However, if you’re not 100% sure, then it’s well worth checking out our in-depth Best Gas Water Heater reviews and our Best Tankless Water Heater reviews.
