Whether we are using it to shower or for washing clothes and dishes. Hot water is an indispensable part of everyday life. A tankless water heater is one of the most energy-efficient options to meet your home’s hot water needs. But finding the right one might require you explore different options. Before you set out, you should check out reviews of different products and models. At the end will require a combination of useful information and essential tips provided by the Electric Tankless Water Heater Review site.
* Gas and Electric Tankless Water Heater Review:
When shopping for tankless heaters or checking out reviews, there are certain important points that you must keep in mind. Since many different types of tankless water heaters are available. Essential to look out for to help you narrow down your options and eventually make the right choice. Here are some important factors to consider when choosing a tankless water heater.
* Consider Fuel:
Regarding the fueling options, a tankless water heater is either fueled by electricity or gas. An important factor to consider when choosing a water heater since either of them offer different benefits, and each has its drawbacks as well.
Gas units are either fueled by propane or natural gas. It is typically a less expensive fueling option compared to electricity. They are making it a more economical choice compared to the electric tankless water heater. The Tankless Water Heaters are also a bit more efficient and faster for heating water than the electric heaters.
However, though gas is a more economical fueling option, an electric tankless water heater unit is generally cheaper to purchase compared to a gas powered Unit. Venting is another major disadvantage of gas heaters. Because of venting issues, gas-powered heaters cannot use when you don’t have sufficient space. They are also larger than their electric-powered counterparts.
Installation is also more complicated for a gas powered unit. In some especially when space is an issue, you might have to go for outdoor installation. Or spend money in setting up extra ventilation and gas pipes if you want to install the gas heaters indoors. Electric heaters are also prone to combustion which makes them a more reliable alternative in the long run.
Your final choice depends on personal preferences and also on the availability of fueling options. A gas powered unit will be advisable if space is not a barrier and fuel is readily available. However, if the area is a barrier and you don’t mind power costs. Then you might want to look at an electrically powered unit instead.
* Water Consumption:
Another important factor to consider before the Tankless water heaters is how much water you will be making use of in your home at any given point in time. Choosing a heater that cannot handle your home water supply needs means you might end up with cold water when its carrying capacity exceeded.
Calculate how much hot water each of your household fixture will use and many of them you will have to operate simultaneously. It will help you determine the flow rate (measured in GPM or gallons per minute). Once the flow rate of each of your household fixtures like shower, dishwasher, etc. has determined, you can then add each of these flow rates together to determine the flow rate that your tankless water heater must be required to deliver before you can purchase it. Generally depends on the size of your household and how much you use water.
The Tankless Water Heaters rated in BTU (British thermal unit) this determines the flow rate of the heater. BTU is the amount of energy that the heater will require to raise the temperature of water by one degree. Thus, the higher the flow rate of your home from your calculations. The higher the BTU of the heater that you will need to purchase.
Generally, you will need a heater with a BTU rating of 31,000 to deliver 1.2GPM of hot water and up to 190,000BTU for a flow rate of 5.7. This value also varies depending on the incoming water temperature as will be discussed later.
* Water Temperature:
Another factor is the average temperature of water which your heater has to warm up. It varies from one region to the other depending on the climate. As expected how much work your heater has to do is to determine by the temperature difference between the water in the pipe. And the desired hot water temperature. In most cases, you will wish your tankless water heater to raise the temperature of your water to about 105–115°F.
* Energy Efficiency:
Another point to consider is the efficiency rating of your tankless water heater unit. It’s important especially if you are concerned about your energy consumption. The efficiency rating of your heater indicates how much of the fuel is converted to heat by the unit. Generally, the higher the efficiency rating, the better the Unit performs. In most cases, the efficiency ratings vary from 78 to 87%.
Choosing the right tankless water heater depends on a combination of factors all of which you have to put into consideration when making your choice. For example, If you use two showers in your home with each with a flow rate of 2.6gpm, and the temperature of the water supplied to your home is 50°. And you want to raise your water temperature to 104 first you have to ensure that your water heater has a capacity of at least 5.3 GPM. Also, it must be able to produce a minimum temperature rise of 50 degrees for optimum performance. Only when calculated this way, can you truly determine the right type of heater for your home?
