Considerations for the Best Tankless Water Heater
When you finally decide to go tankless, you need to know what to look for to get the best there is on the market. Here are a few indicators you need to look out for to get the best tankless heater that’s also suitable for your needs.
Hot Water Flow Rate
All tankless water heaters have an indicated flow rate, which is the amount of hot water a heater can put out in a minute.
This flow rate can be lower than indicated, depending on the groundwater temperature. The lower the temperature of the groundwater, the lower the flow rate.
If you are looking to get a high volume of hot water from your heater, such as for a large family, you ought to get a heater with a high flow rate. Otherwise, it’s better to get a lower flow rate to save on energy costs.
Tankless water heaters can cost more than traditional heaters in most cases. When you get one, you want to ensure that you are making a worthy investment in the purchase.
The only thing that can give you this confidence is the kind of warranty offered by the manufacturer. A longer warranty means that the manufacturer believes in the heater, which means you can too. It also means that should you encounter any problems you will easily get help.
If you are shopping for a tankless heater, you need to consider the cost of one. Just know that paying more for a heater does not guarantee quality. You can still get a cheap heater that still meets all your needs.
Another important consideration when it comes to the cost of a heater is the cost of energy. You can get a cheap heater that will cost you a lot in terms of energy. Such a heater may not be worth buying, as it will be more expensive in the long run. On the other hand, you can buy an expensive heater that is very energy efficient – and in the long run, this could be a worthy investment.
The energy factor is the rate at which supplied energy is converted into heat energy. In an ideal situation, this rate should be 100%. Obviously, this is not the case with most heaters. The best you can do is ensure that this figure is as close to 100% as can be while still having other qualities you are looking for.
The higher the energy factor, the more energy you will be saving.
The size of the heater you are buying is another factor you should pay attention to. If you are pressed for space, you should look for a small compact heater that doesn’t take up much space for installation.
The two major energy sources for tankless water heaters are electricity and gas. Gas water heaters are more cost effective, making them suitable for large families and their water heating needs. If you have a smaller family, however, an electric water heater can serve your family sufficiently.
Tankless Water Heater Frequently Asked Questions
1) What’s the difference between tank heaters vs. tankless water heaters?
Apart from the most obvious one that one has a tank and the other one doesn’t have one, there are some big differences in the energy consumption of these two.
While a tank water heater heats and keeps reheating the water in the tank to keep it ready for use, a tankless water heater heats water as it passes through the pipes when the faucets are turned on. As a result, a tank water heater uses a lot of water to keep the water hot while a tankless heater doesn’t need any standby energy.
2) What’s the best flow rate for a heater?
As I mentioned earlier, the flow rate indicates the amount of hot water you can get from a heater in one minute. If you have a large family, you might need a higher flow rate than if you have a small family.
3) How long does a tankless heater last?
This depends on the quality of individual heaters you’re considering, but one of the benefits of a tankless water heater is that most of the time they last longer than tank water heaters. This is because they don’t corrode like tank water heaters do. Some have a life expectancy of up to 20 years, which is very impressive.
Tankless water heaters are a revolutionary technology that have completely changed how people heat water in their homes. They help save a lot in terms of water heating costs.
While the best water heater will be determined by your home’s individual needs, we think that the Rinnai V65iN-Natural Gas Heater is a pretty solid choice for a tankless water heater.
