There are several types of hot water heaters available on the market. These appliances are used to dispense near-boiling water, and there are various models in different styles and forms, ranging from contemporary to modern and suitable for various budget levels. Some instant water heaters also double as a water purifier, since they may include complex water cleansing filters. Also, there are mix heaters which may also dispense cool water when necessary.
Usually, the tank used by instant hot water dispensers is installed under a sink, connected to a standard sink hole. When you open the tap, the hot water in the tank flows from the spout, while the tank is filled with cool water which is then heated so it can be used in other occasions. Some heaters are quite powerful though, and they can heat the water in the tank to near-boiling temperature in a matter of few minutes. While looking for the right instant hot water heater, you should try to get a model that matches as closely as possible the demand for hot water in your household.
There are essentially two types of instant water heater solutions: portable and non-portable. When it comes to portable water heaters, you can choose between boil-on-demand heaters and electric kettle water dispensers. These devices are small, inexpensive and they don’t require installation or maintenance. Usually they only boil a small amount of water, and even though they are very fast (taking less than one minute to do the trick, generally) it’s not exactly instantaneous. They have to be refilled manually and they’re usually used to quickly boil a few cups of water to make tea. Electric kettles do waste some electric energy to keep the water temperature at the desired level after it boils, whereas boil-on-demand devices just boil the water, they don’t keep it hot.
If you’re looking for non-portable water heaters, then what you need is a hot water tank dispenser. This is a larger device that will connect to your water pipes, which is good since it will be able to refill on its own; however, it also means that you will need the help of a professional such as a plumber to install one of these heaters. They include a tank where the hot water is stored, which can be of different sizes depending on the model; large amounts of hot water can be accessed with these tank heaters, so they’re normally used to heat water for the shower or the bath.
Some models also include special features such as a thermostat which can be used to regulate the water temperature and a water filter that improves the water purity, in case it’s meant to be used in the kitchen. Hot water tanks also waste some electric energy to maintain the water temperature, after it’s heated to the desired temperature – thus making it feel like you have instant hot water.
Choosing the right instant hot water heater for you depends on two main factors: the amounts of water you need to heat and the desired application. If you just need a small portion of hot water for making tea, you just need to get a simple on-demand heater. If you sometimes also want hot water for cooking, you will probably be happier with an electronic kettle. If you want higher amounts of hot water in the kitchen that may be used for either drinking or doing the dishes, you should get a hot water tank with embedded filters.
If you’re looking for an appliance that provides you with hot water for your bath or shower, then you need a hot water tank dispenser. You should try to get a instant hot water heater with a tank that’s neither too large nor too small. Because if it’s too small, you’ll probably run out of hot water frequently, and if it’s too large you’ll waste electric energy for no good reason. You should look into how long it takes for a water heater to heat a full tank, and judge if the water volume in the tank should be enough to provide for you hot water needs during that amount of time.
