All water heaters, as the name suggests, provide a home with a steady supply of hot water for cooking, bathing, and cleaning. Different designs and power sources, however, accomplish this task in very different ways.
In general, the major decision you will have is whether to go tank or tankless. Best electric water heaters keep a large supply of water heated for use, making them more suitable for larger homes. Since tanks store the hot water, they are susceptible to heat loss depending on the design and build materials of the tank itself.
Tankless options, on the other hand, rapidly heat up water using gas or electric heating elements as the water passes by towards the faucet. This makes them quicker while potentially limited in the amount of hot water they can supply at any given time.
We researched the best tank, tankless, gas, and electric water heaters on the market to help you find the right one for your home’s needs.

How to choose the best electric water heaters
So long as you know what you’re looking for, you can be confident buying any of our recommended water heaters that fit the task. However, sometimes you don’t know precisely what you need, and comparison shopping can become rather overwhelming.
Understanding tank storage vs tankless water heaters
There are two primary types of water heaters you’re most likely to come across in your comparison shopping: tank storage, and tankless heaters. Obviously, one has a tank while the other doesn’t. But do you know the significance of that difference?
A traditional tank storage heater has a definite amount of water it can dispense, while a tankless heater can, in theory, provide continuous heat. Warm water from a tank tends to be extremely consistent–until it suddenly runs out.
Tankless heaters, on the other hand, will have to work harder if the mains are very cold. If you’ve picked an underpowered tankless heater, you’ll find it serves you better some months better than others.
If you tend to use around 150L or less of water per day, the tankless heater wins the efficiency contest hands down. This is because it only heats water as you need it, rather than expending energy to keep a reserve tank hot all day. Once again, though, the temperature of the water in the mains is a mitigating factor in how efficient your tankless heater is. If you live in a particularly cold climate, you can expect your electric water heater to work a good bit harder to reach par.
That said, tank storage heaters typically use natural gas, which is itself a clean, efficient fuel source. If you use a lot of water per day and have an adequately large tank, you might actually see lower bills with the tank storage heater. It is, however, paramount to get a well-insulated tank, as cold weather will increase the amount of fuel consumed to reach the preset temperature. What’s more, your tank may wait on standby all day, and you don’t want it bleeding heat due to poor insulation.
Purchase, installation, and maintenance costs
Typically speaking, tankless heaters are more technologically advanced than their traditional, tank-fed counterparts. Thus, they boast higher price tags for equivalent performance. Tankless are also more difficult to maintain and repair, as they require specialist parts and labour.
It might sound daft, but some heaters withstand water and moisture far better than others. After all, electronics and water are a poor combination without proper hydroelectric insulation, and rusty components can lead to decreased performance or even danger.
Flow rates and capacities
You’ll often see water heaters rated for a certain number of litres–and the numbers can vary wildly from 1 or 2 litres up to 30 or even 50 litres! Even tankless heaters seem to have some sort of capacity, what gives?
There are as many types of electric water heaters as there are applications for them–and then some. You may need a miniature, oversink water heater for your workshop or cloakroom; or you may need something much larger to supply hot water to multiple rooms throughout the house simultaneously.
Whatever the case, we’ve reviewed a few of the best water heaters for any application. We’ve also given you some tips we hope will prove helpful in informing your own comparison shopping beyond this article.
