Electric water heaters are a popular choice as electricity is one of the most readily available power sources in the US. If you’re in need of a new water heater, you probably haven’t changed yours for a good few years, and you will find they have upgraded in technology and energy efficiency.
Here is a quick guide to choosing the right brand of electric water heater without breaking the bank.
Choosing an Electric Water Heater Brand
Choosing an electric water heater can be tough with so many on the market to go through. You’ll find you hear the same brand names over and over, and it can be challenging to decipher why one is better than the other. Often it is less about the brands themselves and more about which brand is right for your needs. Here are a few considerations to take into account.
The first thing to consider is your usage habits. In your household, what needs hot water and how often is it used. If you have a dishwasher, washing machine, and several bathrooms that all seem to be pumping out hot water in the first few hours of the day, you’re going to need something with quite a considerable capacity. This doesn’t necessarily mean that you need a water heater with a huge tank though.
When buying a tank water heater, you want to think about the FHR or First-Hour Rating. With a tankless water heater, you’re looking for the GPM or Gallons Per Minute. These ratings will give you an understanding of how much hot water can be produced over a given time. If you do not have a need for great amounts of water, you only need a small rating, otherwise, it will be hugely inefficient. However, if you have a big family and a lot of demand, higher ratings are more ideal.
When looking through the brands of water heaters, you need to think about what they have on offer in their range. There are three main types of water heaters: tankless, storage tank, and heat pump. A storage tank heater heats a large amount of water and stores it in a tank whereas a tankless heater simply heats the water as it comes out instantaneously and on-demand.
A heat pump water tank captures heat from the air and heats the water with this. Each has its own advantages and disadvantages, and preferred application scenarios, however, you first need to consider whether the brand you desire carries the type you want.
For example, if you are not that worried about energy efficiency and would rather simply retrofit your old tank system, EcoSmart would not be the right brand for you as they focus on energy efficiency and only make tankless water heaters.
The warranty that a brand offers will often determine the level of quality you are receiving. A brand that offers a lifetime warranty is far less likely to break in the first year than one with a very limited warranty. While most water heaters come with warranties from 3-12 years, you will find, however, that the longer warranties tend to cost you a bit more.
Equally, don’t just take the warranty at face value. Although the warranty may be long, often it is ‘limited’ which means it excludes certain issues. Make sure to check this out first as it may be an indication of future flaws in the system. Also, have a look at customer reviews to see how well the brands honor their warranties in the face of dispute.
Some brands put a real emphasis on energy efficiency and eco-friendliness. These tend to be brands that offer better efficiency ratings. A shortcut to seeing whether a brand is offering energy efficient products is to look for the Energy Star seal as it certifies that they are energy efficient.
A water heater brand can achieve this by meeting the criteria for Energy factor (an old way of measuring efficiency), Universal Energy Factor (the new way of measuring efficiency), standby loss (the amount of heat lost from the water heater while in use, such as that through pipes) or Thermal Efficiency. Often you will also see brands display the percentage of efficiency that a heater has, such that a water heater that is 95% efficient only fails to convert 5% of its energy to heat.
When considering durability, you can look for customer reviews to see how well each brand fares in their longevity. Often you’ll find reviews that discuss the lifetime of the internal parts and how easy it is to replace them as well.
You can also look for features that improve longevity. For example, glass lined water heaters are protected from erosion caused by rust due. Equally, some waters heaters contain anti-scaling devices that prevent the buildup of limescale residue inside the water heater, even in hard water areas.
Maintaining Electric Water Heaters
Maintaining an electric water heater is important to improve its longevity. The first way to do this is to keep it at a slightly lower temperature. When kept at a high temperature, it forces the water heater into overdrive, which is hard on the components inside.
You need to check your temperature and pressure on a yearly basis at the very least. This is pretty simple to do; simply discharge the valve a couple of times. If water is coming out the valve or the valve won’t go back to its original position, then you have an issue, and you may need a plumber.
Insulation is key to ensuring that you get the most efficiency from your water tank, but also keep it in good condition. Insulating both the tank, if you have one, and the pipes are important. Insulating the tank prevents standby loss while insulating the pipes prevents heat loss as well as the pipes freezing up in the colder months. It is even important to insulate the cold pipe as it can be subject to condensation in the summer.
Take a look at the anode rod. This rod is probably one of the most important indicators of durability. This rod is used to prevent the tank from rusting and filling up with deposits. You need to take out the rod and see what state it is in. If it is less than half an inch thick or it is covered in calcium deposits, it needs to be replaced.
Lastly, drain your tank every year. Draining it releases any sediment and deposits that come from your well or your main water supply. Drain the tank into a bucket and then flush it with the cold water supply. Keep doing this until the water drains clear.
A Look at the Major Players
Each of the brands available on the market has its own pros and cons. Their underlying principles lead them to be specialists in different areas. Here’s a quick guide to what you can expect from each brand.
