What Is a Tank Water Heater?

All the time we seek new means that could make our household life more comfortable and less stressful. Today it's almost impossible to imagine a house without such amenities as gas, electricity or hot water. The thing, however, is that we wouldn't have had all these conveniences if not for certain appliances, like oil heaters, for instance. They help us keep our homes warm in the wintertime.

In this review though, we're going to give a rundown on popular water heaters that are widely used by people as a main or emergency source of hot water for washing dishes, taking a shower, etc. In order to help you choose, we have narrowed down to the five best electrical water heating tanks that are ideal for frequent use in the kitchen or in the bathroom under or over the sink thanks to their compact design and simple installation. They heat up quickly and can supply you with hot water anytime you need it. Plus, they are eco-friendly that is great when the economical operation is a priority for you.

What Features to Compare

Type

The choice of a water heater depends on certain requirements against the features like size, capacity, and so on. It's important to understand the difference between various water heaters to be able to pick a suitable one. First of all, you should know that some heaters are electric and others are gas-powered. The latter are usually powered by natural gas or butane (some heaters are oil-fired) and fitted with exhaust pipes to draw out exhaust fumes. Electric water heaters do not need any air pipes, what they need, however, is connecting to a power grid.

Technical Details

Before you decide on a water heater, you should ask yourself several questions, how big is your family, why exactly you need a water heater, is it going to be only a backup water source supply or maybe you need it for regular use? Your own answers will help you choose the right capacity and power of the heater you need. People who live by themselves shouldn't overpay for big water tanks, while if your family is rather big, you wouldn't get along with a tiny water heater. The power should be considered too. It will tell you how quickly the heater can heat the water and how long it would take it to run a new cycle.

Special Features

Nearly every water heater has certain special features that can provide users with extra convenience. The heater should be equipped with user-friendly controls and convenient inlet and outlet connections. It may also feature an information display on the front. Don't ignore the material; tank water heaters should be made of corrosion-resistant material and feature a protective inner layer. This is the only condition you can be sure of great performance and long service life of the chosen heater.
