Tankless Water Heater FAQ
After reading our electric tankless water heater reviews, you probably have a good idea of the product you’d like to purchase for your home. But let’s look at some frequently asked questions about on demand electric water heater products in general.
Is a tankless water heater worth it?
One of the biggest reasons why you might be interested in purchasing a tankless water heater is to save money on your electricity bill. If so, there’s good news.
You can save more money on hot water because the water gets heated as you need it, instead of being stored in a tank.
There are other benefits of electric water heater tankless products.
- They save space. Gone are the days when your water heater had to be put in the attic. With tankless water heaters, you can easily store them anywhere in the house because they are much more compact than traditional water heaters. Some even enable you to quickly and easily store them underneath your sink or cabinet. An example is the Camplux ME40 Mini Tank Electric Water Heater that’s featured in our tankless water heater reviews.
- They work immediately. The best tankless water heater electric products are convenient for your lifestyle. With traditional water heater tanks, you have to wait for the water to heat up before you can wash the dishes in winter or step into a hot shower. These situations can be prevented with the use of an instant hot water heater electric model because it’s always ready to give you hot water when you open the faucet.
- They last longer. The average water heater tank will last you approximately 10 years, but tankless water heaters are capable of lasting double that amount of time, as YGrene reports.
- They prevent standby loss. Traditional water heaters will keep reheating water so that you have it when you need it, but this means that they’re notching up energy costs. With tankless water heaters, you prevent this extra cost and standby loss –this is defined as the energy that goes to waste when hot water in the pipe cools or when it sits in the storage tank, as Energy Depot reports.
What is the downside of a tankless water heater?
Although a tankless water heater has lots of benefits, there are some disadvantages to consider. These include:
- They don’t give you unlimited use. Although you can usually use two sinks or a sink and a shower simultaneously with the use of a tankless water heater, that doesn’t mean you can do lots more. There’s not enough hot water available for all those tasks.
- They don’t always give you a constant hot temperature when the flow rate varies unless they have modulating temperature control. This could especially cause you a problem if you have water pressure that varies in different spots in the house.
- They can’t give you hot water during a power outage because they need electricity to heat the water. However, the use of a gas-powered unit can help in this regard. An example of an effective gas tankless water heater is the Rinnai V Series HE Tankless Hot Water Heater that’s featured in our best rated electric tankless water heater reviews.
How does my tankless water heater go cold?
There’s a term used with tankless water heaters that’s known as cold water sandwich.
What this refers to is sudden fluctuations in temperature that can make your tankless heater produce both hot and cold water at the same time. This can be caused by various things. As My Dad Can Do That, reports these things can be the culprit:
- A plumbing system crossover that shouldn’t be there. A crossover is defined as when cold water flows into the hot water system.
- Venting pipes that are not of the right length.
- A damaged flow sensor.
- A dirty water filter on the cold water inlet.
- Corroded lines, such as because there is condensation dripping on the gas burner.
- You’re pushing the heater to its limit. There’s only so much that a tankless water heater can do, so if you’re trying to get a lot of hot water running at the same time, this can cause cold water to come out instead.
- Your tankless water heater shuts down during use, which can be as a result of its minimum flow rate not being met. This is the minimum amount of water that the unit requires so that it can give you hot water. If this amount isn’t being met, then the unit will shut off as a safety measure.
How much you can save with the water heater on demand?
If you’re hoping to save water and money by purchasing a tankless water heater that gives you hot water on demand, then you’re in luck.
The U.S. Department of Energy states that gas-powered tankless water heaters will save you an average of $108 in your yearly energy costs when compared to traditional tank heaters. Also, electric tankless heaters can save you around $44 per year, Abacus Plumbing reports.
Also, these products are between eight and 34 percent more energy efficient when compared to tank water heaters, as Smart Wheater reports.
When it comes to how much it costs to purchase a tankless water heater, you can expect to pay between $1,500 and $2,000 which includes installation, but as can be seen in our tankless water heater reviews, this amount can be much less without sacrificing on important features such as durability.
For example, the most expensive tankless water heater on our list is approximately $600 while the most budget-friendly is approximately $150.
By comparison, a whole-house tank will cost approximately $430 without any installation, and a traditional water heater will be around $440, as Fixr reports. So, if you shop in the right places, there isn’t much difference in price between traditional and tankless water heaters.
What’s really important is that you can save more money on your electricity bill and water usage when owning a tankless water heater.
Investing in a tankless water heater is better for the environment because it saves water, it’s better for your wallet because it saves money, and you can find many types of tankless water heaters that suit your lifestyle, whether you want to use one at home or on the road.
In this article, we’ve featured the best on demand water heater for the money and provided you with alternative products that can save you more money or give you other features you might want in a tankless water heater.
