electric tankless water heaterAre you searching for the best electric tankless water heater?

Heating water for several functions has nowadays become a basic requirement for every home. To serve this purpose, people are currently using water heaters that vary across different prices and models.

They are high power heaters which heat water instantly in an efficient manner.

In addition, they do not retain any water internally. This kind of heaters is normally supplied with flow sensors which activate it once the water travels through them. The water then circulates through the device and is warmed by electricity or gas. They are coated with sturdy coatings so as to shield them from the acidic environments.

How To Choose a Best Electric Tankless Water Heater:

The heater technology is always changing. Even though all the new heater models are designed to be more energy efficient, this does not mean that you will find them as the most cost-effective tankless water heater for your family.

Therefore, before buying a high-tech heater, you should take a minute and understand how each model works, its pros, cons and the projected payback. Your goal is to find the correct balance between efficiency and performance for your particular home.

Here are the factors to consider while choosing an electric tankless water heater:

CapacityRating EfficiencyTemperatureCostsFuel TypeDemands
Although some consumers normally base their purchase of water heaters on the storage tank’s size, the peak hour demand capacity, also known as the FHR (first-hour rating) on the Energy Guide labels, is in fact, the most important figure. FHR is the measure of the amount of hot water that the heater can deliver during busy hours.

Therefore, before buying a tankless electric heater, you should estimate the household’s peak hour’s demand and then look for a heater with an FHR that’s in that range.

Once you’ve decided the type of water heater that best suits all your needs, you should then determine the water heater in that category that’s the most fuel efficient. The best indicator of a water heater’s efficiency is the EF (Energy Factor), which is based on the recovery efficiency. The higher the Energy Factor, the more efficient the heater.
Gas tankless heaters are capable of producing a large temperature rise per GPM as compared to electric models. Most water heaters are rated for a wide range of inlet temperatures. Normally, a 70F temperature rise can occur at a flow rate of five gallons per minute via gas-fired water heaters and two gallons per minute via electric ones. Cooler inlet temperatures or faster flow rates can reduce the water temperature at times. Thus it is important to consider the temperature while purchasing electric tankless water.
Another factor which should be uppermost in most consumers’ minds is the cost, which encompasses the purchase price as well as operating expenses and lifetime maintenance. When you have to choose among different models, it’s wise to analyze well the life cycle costs, the total costs and the benefits associated with the purchase during its estimated lifetime.
Best electric tankless water heaters can be heated using different fuel sources. The 2 most common sources of fuel in homes are electricity and natural gas. When you are comparing electric and gas water heaters to buy, one of the important factors to be considered is each heater’s annual operating costs. Even though gas water heaters are usually a bit expensive to install than the electric heaters, the operating cost of gas heaters is much lower and can result in long-term savings on utility bills.
It is important that the type of water heater that you choose is correctly sized for your home. There is no point in paying more money for a water heater which is too large for you.

However, you also do not want a unit which is too small to meet all the demands of the home when you require hot water the most. When you are buying a water heater, ensure that its 1st-hour rating is large enough for your entire home.
