How Does An Instant Hot Water Heater Work?

instant hot water heaterSo you have been using your tank-type water heater for years and now it’s no longer working. Chances are, you’ll still have it checked by professionals to find out if it can still be repaired or the otherwise. If it doesn’t, then you’ll have to put up with boiling water every time you want to take a hot bath. But if you are thinking about investing on a new heating system, then you might want to consider an instant hot water heater. Before you go crazy just thinking about how much it costs, let us first weigh its advantages and disadvantages. How does it work in the first place? Why is it referred to as the demand-type water heater? Read on and get some answers.

How does a hot water heater work?

An instant hot water heater obviously does not have a tank where it’s supposed to store water for heating. It heats water by demand. That means it only makes use of its heating capability whenever you turn on your hot water tap or your shower’s hot water knob. This type of heating system is popular in Japan and in Europe for quite some time and is now gaining popularity in the United States. Now there are two main types of tankless water heaters: the whole house heater and the point of use heater.

The point of use heater is relatively small and can even be stored inside a cabinet. What it does is supply hot water to a specific plumbing fixture only. For instance, you only want to get hot water from your kitchen tap. Thus, you’ll have the heater connected only to that faucet. You can also have another unit connected to your shower if you are a sucker for warm baths.

Meanwhile, the whole house heater can supply hot water on more than one fixture. You can have it connected to your dishwasher, your shower, your kitchen faucet or anywhere else you’d like to get instant hot water from. Just remember to check the flow rate of the unit you’re eyeing to make sure that it suits your needs.

What are its advantages?

The tag price is one reason why homeowners disregard the purchase of a tankless water heater. It’s really more expensive than the traditional tank-type units. However, if you’ll consider its advantages, you might actually be convinced into buying one.

First of all, since the heater doesn’t have a tank and doesn’t heat such a large amount of water every time you demand it, it produces less energy or standby heat loss. Meaning, it won’t only save you money on your electricity bill but also save you money on your water bill. To put it simply, it only heats water as needed. Another advantage is that it is durable. As compared to traditional heaters that can last 7 to 10 years, instantaneous units are known to last for as long as 20 years. When it comes to maintenance and repair, a tankless unit is also less demanding. It doesn’t have a tank that you’ll need to flush and check on regularly. You won’t have to replace anode rods or worry about leaks in your basement. That said, it will also save you a considerable amount of repair expenses.
