Frequently Asked Questions

1. What Is A Tankless Water Heater?

Tankless water heaters are energy efficient, money saving devices that allow homeowners to save on conventional hot water heating by preventing the need for storage tanks. Tankless water heaters are not only more energy-efficient, but also more reliable than conventional tank heaters, which can experience mechanical problems such as pump failure and loss of refrigerant. In addition, tankless water heaters are safer than conventional tank heaters because they do not store water internally, only heat the water that is delivered to the faucets. tankless water heaters are especially popular in rural areas because of their convenience and energy efficiency.

Tankless water heaters provide families with hot water whenever they want it, day or night. Because tankless heat pumps use an energy source that is nearly free, most tankless water heaters are priced at just a few cents per gallon. Even the smallest tankless water heaters use less than one tenth of a pound of fuel, making them extremely cost-effective. The energy savings are compounded over time, which means that your heating costs will be much lower than if you were to use traditional heating sources, such as furnaces and gas burners.

Some tankless units use a small amount of fuel to provide enough hot water to run the whole house, while other tankless units use a larger amount of fuel to provide enough hot water to run several small water units. One tankless unit that uses a smaller amount of fuel and heats water only when the tank holding it is filled with water is called a peak demand water heater. peak demand water heater: provides enough hot water for a home of approximately 15 to thirty gallons; uses only three to five gallons of fuel per cycle; requires a minimum of one hundred eighty-five gallons of water to operate on a daily basis. The maximum daily capacity is two hundred forty-one gallons.

2. How Can A Tankless Water Heater Heat Water Instantly?

How can a tankless water heater heat water instantly? This is a question many people often ask when considering the switch to an energy efficient unit, but there are several reasons why it’s impossible. First of all, because water only makes up about 3% of the heating load in most homes, you really don’t need a large tank. Smaller water heating units have almost no effect on your electricity bill, so you will save a lot of money in the long run.

Second of all, these units are more efficient, which means that you will pay less in the long run. As stated earlier, they have a much longer expected lifespan, and a smaller unit will be much less likely to break down in severe use. The main drawback of tankless water heaters, however, is that their upfront cost (installation and unit) is usually much higher than traditional tank-style heaters.

Finally, a tankless water heater will not increase your energy efficiency because you will no longer be using gas or electricity. Although both of these sources have pros and cons, it is better to go with a natural gas or electric model. It is very possible to retrofit an electric model over a gas one, making them extremely energy efficient. Even if you choose to go with natural gas instead, your utility company may offer you rebates for using alternative energy sources (even gas heaters). In addition, you should check with your local building codes to see if your new unit will be required to have an efficient heat exchanger.

3. What Are The Advantages Of A Tankless Water Heater?

There are many reasons why more people are choosing to install a tankless water heating system in their home. In addition to energy and cost saving, there are also many other advantages to choose a tankless water heating system over a conventional tank style heater. Tankless water heaters provide an unlimited amount of hot water at a very low cost per gallon, require little room to store water and can save thousands of dollars in monthly energy costs. Tankless water heaters are also safer, produce much less risk of leakage, have a longer lifespan on average, and produce an unlimited amount of warm water. The following article will outline the top three advantages of tankless water heaters to help you make the best possible decision.

One of the top advantages of tankless hot water heater is that the installation costs are much less than those associated with conventional tank type heaters. Tankless heaters require very little building, plumbing, or wiring to install. This is in stark contrast to the installation costs of tank heaters. The cost of a tankless water heater can often be less than half of what is required to heat and maintain a conventional tank style heater.

Natural gas and propane are the most common sources of power for tankless units. Because natural gas and propane are clean burning fuels, these types of heating units reduce the carbon footprint of your home while providing a steady hot source of hot water. These units are also much more convenient than conventional heating units because they provide a constant hot supply of water even if your home’s natural gas or propane supply is out of service for one reason or another. You can also expect these types of units to provide much higher energy efficiency than their tankless counterparts.

4. Will One Tankless Water Heater Be Enough To Heat My Entire House?

If you are planning on installing a new water heating system in your home then you should consider the efficiency of one tankless water heater. Since they only require one installation, and you can easily relocate it if necessary, they are extremely energy efficient. They are also more likely to use energy than traditional hot water heaters since they are only heated when the hot water is needed. This cuts down on your electric bill by not using the service for a prolonged period of time.

Now that you are already aware of how efficient these types of units are, it would probably be best to ask a professional about how long it would take to actually heat your home. There is no point in installing one if you won’t ever use it, right? So, ask your professional if it will take as long as two years for one tankless water heater to heat your entire home. This will give you a pretty good idea of how much money you will need to set aside in order to have the system installed. It may even be possible for you to save money on your energy bill this way, as some systems will use less energy than traditional systems. You will most likely pay more up front, but in the long run it will be more cost effective to use one heater throughout your home instead of two.

When you decide to purchase a new water heating system make sure that you ask yourself the question, “Is one tankless water heater enough to heat my entire house?”. It’s important that you do your research, and get all the facts before making a decision. Make sure that the model you choose is energy efficient, and that it will provide you with enough hot water during the summer and winter months. Also, make sure that you ask your professional which heating units they recommend for your house.

5. What If I Have Hard Water?

What is Hard Water? Water which is extremely mineral and not very pure is known as hard water. Generally, this type of water is not suitable for consumption. It freezes up in pipes, clogs sinks and other fixtures making it difficult to use. Water which is hard due to high minerals contains more sodium than salt and as a result, poses problems during treatment.

Tankless water heaters are used with electricity to reduce the amount of hard water in the household. Hard water contains high dissolved minerals which make the process of distillation difficult. Tankless water heaters use a combination of electricity and heat to change the hardness from hard to soft. With the installation of tankless water heaters, there is no need to filter the household water as it is changed on demand and with ease.

To understand the entire process of tankless water heater, it is important to have an understanding of how a tankless water heater works. As water enters the tankless heater it is heated and the heat exchanger heats up the water coming in. The heat exchanger heats the water until it is at the proper temperature to meet the needs of the household. After the water is heated, it exits the tank through the heat exchanger down a heat pipe. This process continues as long as there is a constant flow of water going through the tankless heater. Once the flow stops, the tankless water heater shuts off and the unit is drained.

6. How Do I Properly Size My Tankless Water Heater?

If you’re just beginning your search for a tankless water heating system, then you’re probably asking, “What size tankless water heaters do I need?” There are two basic types of tankless water heaters that are currently on the market. There are also tankless water heaters with two tanks – one large tank that is placed on the exterior of the building and one smaller tank that is placed inside the building. The type of tankless water heaters that use a larger tank and an external unit tend to be more efficient than those that use a smaller tank and an internal unit. In addition to the size of the unit, which is what determines how many gallons can be heated, this also determines the cost per gallon.

Tankless water heaters have several advantages. They are most often used in public buildings such as restaurants and public restrooms, but they are also used in homes for a variety of purposes. In addition to being space savers, they are also quiet because there is no need to vent the furnace; therefore, there is no noise associated with running it. Another advantage of tankless water heaters is that they are quieter than conventional units since they do not require a fan to circulate the warmed air.
