Best buying guide for Tankless Water Heaters

We are faced with countless decisions each day and heating water is a daily thing all of us do. Water heating accounts for roughly 20% of your household budget and it only comes second to your heating and cooling of your home. This is an enormous part of your budget so why won’t you want to get one? With a tankless water heater, you can cut back on cost and save thousands each year. This guide will give you insight on what to look out for when buying a tankless water heater.

 

 

The difference between a normal and tankless water heater 

 

Traditional water heater – A traditional water heater with a tank is used to supply your home with continuous hot water until the tank runs out. It stores water that heats up over and over again even when it is not in use. This means it negatively affects your budget through this wastage of electricity heating the water.

Tankless water heater – A tankless water heater on the other hand only provides you with hot water when you need it. The system is effective and costs effective on your budget. And unlike a traditional water heater, it will never run out of water because it is tankless.

 

What should I look for when buying a tankless water heater

There are a couple of things you should look out for before getting yourself a tankless water heater. The first time you make use of your hot water faucet the heating elements in the tankless water heater will heat the water as it flows your way.

Water pressure – In return you will have a never-ending water supply but this comes at a cost. Because the heating elements will require some time before the water is fully heated up, this will decrease your water pressure considerably.

Mostly they will produce a water flow of between 2-5 gallons per minute and some can even reach 11 gallons per minute. However, this should not be a cause for concern as your morning shower tops out at 2.5 gallons per minute.

Household size – If you plan on using the tankless water heater to supply hot water to countless faucets around your home this may be problematic. They typically only supply hot water to one tap. This means you will have to install a couple of tankless water heater to maintain the demand issues. However, the US Department of Energy said in a statement that if your household uses 86 gallons of water per day you will start saving on energy costs considerably.

Electric units’ vs Gas units – There are mainly two varieties when it comes to tankless water heaters a gas or electric unit. A gas heater will use a larger gas line than conventional water heaters thus requiring more wiring which will cost more in the long run. However, the gas heaters will heat water faster than an electric unit. When using a gas unit the pilot light is always on even when you aren’t using any water and in so doing uses more energy. But if you still set on getting a gas look for one with an intermittent ignition device which will allow you to turn the pilot light off.

 

 

 

 

What is the downside of a tankless water heater

It’s not all sunshine and roses when dealing with tankless water heaters, there are a few downsides about the product that you should know. It is quite expensive when starting with this product the installation cost and upfront cost will bite your pocket. This may put some people off but you should note that you will be saving more in the long run. Installing costs are pushed up because tank-style water heaters have been around for longer and more people are trained at installing them than the newer tankless water heaters.

Another thing that you should consider is the hard water that is created due to high levels of minerals in the water. This makes tankless water heaters work harder than the conventional ones and leads to premature breakdowns. Some of the manufacturers require you to install a water softening system to your tankless otherwise your warranty will be void. The downside is adding this feature will also push up your overall cost.

 

 

 

What are the advantages and disadvantages of a tankless water heater

 

Advantages

The tankless water heater will only operate when you need hot water. This will greatly reduce your energy consumption throughout the year. You will be able to save between 35-50% on energy costs annually.
