Are Tankless Water Heaters Worth the Money?
Before you choose which water heater to buy, you probably ask yourself, ‘Are Tankless Water heaters Worth the Money?’. You do have the right to receive answers to this essential question. After all, installing a tankless water heater costs a lot. No one would want to do it if it wasn’t efficient. The following part of the article will help you get the answers you need.
Tankless water heaters provide hot water right away whenever you need it. In doing so, they need more power than traditional heaters because they use electric coils. However, the water doesn’t have to be reheated, which makes these devices budget-friendly. According to recent research, tankless water heaters are around 25 % more efficient than traditional ones.
Indeed, traditional water heaters need initially less power to heat the water. However, they keep the water in them always hot, even when it is not being used. Of course, if the hot water is not used, it gets cold at some point. So it has to be reheated. Following this stream of thought, tankless water heaters don’t waste so much energy because they don’t need to reheat any water.
Anyway, before you decide whether to get a tankless water heater, it is a good idea to calculate whether the overall cost of installing the tankless device and the monthly electric bills will be cheaper than using traditional heaters. Keep in mind that tankless heating devices need more energy to heat the water. Check whether your house is prepared to handle such an energy flow. If your home is old, you may also need to rewire it, which will cost some additional more money.
What is the Lifespan of Tankless Water Heaters?
The initial cost of installing a tankless water heater may seem a fortune and may become even the reason for some people to get rid of this idea. However, if you consider how much you are going to save from energy costs, maybe you will decide that the tankless options are worth it after all.
Another factor that you need to take into account is how long you plan on staying in the house in which you want to install the heater. If your plans exceed ten years, then you should know that if you decide to go with a traditional water heater, you have to replace it every ten years. Whereas, the tankless device is supposed to function properly for at least 20 years.
How to Minimize Costs?
If you want your tankless water heater to work effectively, it is advisable to install a water heater timer. Thus you can adjust the heater to function according to your needs. For example, you can set it to turn off when you go to bed, and then turn on again some hours before you will need it. The timer will not only help you to reduce costs, but it will prolong the life of the heater.
Another idea that will help you minimize costs is to reduce the desired temperature. Keep in mind that every 10 degrees Fahrenheit that you cut will help you to reduce your electricity bill with 5 %. Yet another way to decrease energy waste is to insulate the heater using an insulating blanket. This type of insulation will reduce your power costs by around 10 %. As you can see, reducing electricity bills while using a tankless water heater is achievable.
All of the above information is relevant for indoor water heating devices. If you want to understand if outdoor tankless water heaters are worth the money, we will encourage you to visit our exclusive guide on the matter. There you will read our reviews on the top outdoor units and will learn about their benefits and drawbacks.
