Best Water Heater

Article Contents

One of the things that define a civilized society is its supply of clean, potable water. In the United States, we use more water than any other nation, and we use it in more ways than any other nation. Heating water for bathing is almost unheard of in most countries, so remember not to take this for granted the next time you bathe.

The energy used to heat enough water for a typical family of four accounts for up to 30 percent of the average home's energy budget. Deciding what type of energy used to heat your water, and what mode of heating you chose, is very important as it will play a very large role in your day to day life.

There are only a few sources of energy used here, namely electric, gas, oil, and solar. Depending on where you live and how much hot water you consume, these things will dictate how to store your hot water, and what style of hot water heater you should use.

You can have the traditional hot water tank that holds 30 to 80 gallons of water, maintained at a constant temperature, ready to use when you need it. Or you may opt for the newer tankless hot water heater that runs water through a heating element it as you need it. This is far more energy efficient than traditional tanks as it only uses energy when you make a draw on the water. Since the tankless hot water heaters don’t have to maintain a hot water tank, when not in use, tankless hot water heaters will consume no energy at all.

If you live in a very sunny area of the country, you might opt for a solar hot water heating system that is a combination of both. Insulated tubing sits on the roof of your home, being heated by the sun. Once it reaches a certain temperature, it is then pumped down to a tank that will store this hot water ready for use. Because these solar panels sit in the sun all day, they are also generating enough electrical energy to circulate the water, and run the pumps that allow it all to function. If your conditions are right, these can be a very good source of hot water all year long.

Learning all you can about hot water heaters, and discovering all the choices you have is a great way to help make this decision. Please consider, whatever you purchase, you will probably live with it for the next 30 years, or more.

Best Electric Water Heater:

What makes a great hot water heater consists of a few things, the most important being its energy efficiency. The higher the Energy Factor rating, the more energy efficient the heater is. A score that is over two, would be considered a very good score, and certainly qualify for the current tax rebates through December 2013. If a score is not very good, this doesn't mean that it will not qualify, just that it is not as energy efficient as one that does. It is believed that hot water heaters use as much as 30 percent of the typical homes energy consumption, so shopping smart here, will payoff monthly for years to come. Some of the other features will include the warranties, rust-resistance, installation, and how they deal with sediment build up inside. All of these recommended electric water heaters score well in all these areas, and will include a few unique features of their own.

    Best Tankless Water Heater:

    When looking for a tankless hot water heater, you should consider a few things. First and foremost, are the gallons per minute. Making sure your new unit is sized right is very important. Even if your unit will produce the hottest water with the greatest of ease, if it is not enough to shower with, it is useless. So gallons-per-minute tops the list. The next feature will be its efficiency rating. The higher the rating, the more efficient that unit will be. Easy installation is also a consideration, as some people will need units that will fit in small spaces. Thankfully, that is par for the course with tankless heaters, and most of them are very compact, and easy to install. Lastly, a good warranty is important to consider as once purchased it is yours - win, lose, or draw. Most tankless water heaters come with both gas and electric energy options and up to a 6-year warranty on the product. If you shop around you are sure to find something that works for you.

              Best Natural Gas Water Heater:

              Natural gas hot water heaters come in a few styles; hybrids, tank-less, and solar supplemental. Some of the criteria used for grading them include their Energy Star rating; the length of their warranty; their insulating and noise factors; and mostly their energy efficiency. Almost all hot water heating devices come with the Energy Star certification now, as well as a typical 3 to 12-year warranty. An extended warranty is well worth it, as hot water heaters typically dont have problems before twelve years of age. It is at this time, problems will appear if they are going to have them. Some other features that help postpone issues are a brass drain valve, and a glass tank lining to help reduce rust. Some heaters have anti-scaling features, however by getting a heater that has a longer warranty (12 or more years); these will have a longer and thicker heating element that will naturally resist rust.

                    Best Solar Water Heater:

                    Solar hot water heaters are not for everyone, but if you live in an extremely sunny place, they could be right for you. Since these systems typically sit in the sun all year long, it is important for all the metals to be galvanized, and made from metals that will expand and contract well. The rubber seals being used must also be able to withstand extremely high temperatures, ranging as high as 320 degrees. The copper pipes inside the heat collectors must also be built in such a way to minimize joints, to further reduce cracking and leaking. The water tanks themselves, must also be built to last, and should include some type of insulation, a way to stir the water in order to produce an even heat, and an exit valve to permit the owner to rinse and clean the tank periodically.

                      There are only two types of tankless hot water heaters available on the market; the whole house and the point-of-use. The whole house tankless hot water heater is designed to heat water on demand, and do it at a rate that will supply enough water for the whole house. The point-of-use hot water heater is a much smaller hot water heater that stores hot water in a mini-tank, but supplies enough for one bathroom at a time. Based on your need, point-of-use hot water heaters can do the job, and save lots of money by not using the energy it takes to maintain a full tank of hot water. The features to look for in a point of use hot water heater will include its capacity, its UL listing, the type of energy used, a glass lining, a pressure release valve, and its insulating capability.

                          My vote will go for Reliance 6-50DORT Electric Water Heater. One of my relatives is using it for a while and getting great service. So, I's thinking about it. But after comparing the hot water system prices from above, I'm now in a dilemma that would I go for Rheem FVR Natural Gas 22V40F1 Water Heater or not as it's the cheapest but it's drawback is that gas is required for it.
