Here are some basics of water heaters, and what different kinds of heaters are available. A water heater takes cold water from the water supply and heats is up to a certain temperature, ready for you to use.

There are many differences to each type of heater, but they basically have all of these components. A cold water intake is a connection from your water supply line. Water enters here on its journey to heat.

You are going to have some kind of water holding chamber. Many people thing of this at the hot water holding tank. But even tankless heaters store water in coils until ready to heat. (More on this later.) You have a heating unit that is either powered by electricity, natural or propane gas, or even solar energy.

There is a thermostat, a hot water outlet pipe, and a drain valve for maintenance and replacement.

A tank style heater will also have a pressure relief valve, which lets off excess pressure. If left unchecked it could potentially cause an explosion. Each style of water heater may have its own type of monitoring system as well.

Now when you are picking out your new water heater there are some things you need to know. One of them is what your first hour rate is, or FHR. FHR is based on the size of your family, and what variables there are, like more than one bathroom, if you have a large bath, or a Jacuzzi.

The basic guidelines for FHR requirements are; 45-55gallons for up to two people, 55-65gallons for three and so on in 10 gallon increments. These are just the basics, your needs may be more, or less, and standards may change from community to community.

There are two basic styles of water heaters, ones with holding tanks, and those that are tankless, or on demand. Both of these run on electricity, gas, propane, or solar. No matter if you choose tank or tankless, electrical heaters take far more time and energy than gas models. You have some advantages and disadvantages with each kind of heater.

Tank heaters are by far the best water heaters if you want almost instant hot water. Because hot water is stored in the tank, it gets to your faucet or showerhead within seconds.

Many people like being able to have instant hot water, but there is a big drawback. It takes a lot of energy to heat that stored water, and keep it that way. Every time the temperature drops below a certain point the heating element kicks on and heats the water back up.

For people who are trying to conserve energy, cut down on heating up water, and save a little water as well, a tankless water heater can be ideal. The advantages here are that you will use less energy, because the water only gets heated when needed, no tank to keep filled, nothing to maintain, and they usually last longer than a conventional tank model, because there are less working parts.

The drawback is that you will not get instant hot water, and may even go through a whole gallon of water before it is heated to temperature.

A 50 gallon water heater is what you will find in most houses, and many are getting old and worn out. Because of this, many are looking to replace it with a brand new one. Before you do, take the time to check your unit out. While it may be that the heating unit is the problem, what you need to ask yourself is, is it worth it to call someone out and replace it, when it may be cheaper and more fuel efficient to just replace it.

When you are looking to replace your 50 gallon water heater with a new one there are a few things to consider. One of them is will you choose electric, or gas? No matter how high the efficiency rating is, the best bet for a new water heater is a gas one. Some people may argue that an electric one is better and safe, but this really isn’t the case. In actuality a gas heater can not only be safer, but much more energy efficient than an electric one.

One of the biggest drawbacks to a 50 gallon water heater is heating up a full tank of water, and keeping it hot. It takes longer for an electric heater to bring the water up to temperature and more energy to keep it hot. Electricity uses a wire heating coil to heat up the water, where gas heaters use real fire from the pilot light. Since the tank uses direct heat, it reaches temperature far faster and recovers quicker than electric hot water heaters.

If you have natural gas in your area, you should be taking advantage of this option for your 50 gallon water heater. It burns better and more efficiently, and cleaner than many fuels, and doesn’t run out when the power fails. You can have hot water longer, hotter and more of it than electric heaters.

When you are looking to buy your next 50 gallon water heater, here are some tips. The first thing are going to want to look for is the Energy Star Sticker. This will tell you that the heater is a high efficiency unit, and the higher the rating, the higher the energy savings. No matter what heating source you plan on using, make sure this number is the highest you can afford.

The other thing you need to look for is a warranty, the longer the warranty the better off you are. Realistically, a higher warranty only adds fifty to a hundred dollars more than a model with a shorter warranty, so you might as well just spend the little bit extra to get many years of service from your unit.

Usually when you get a longer warranty, the 50 gallon water heater is manufactured better. The heating element will be larger, and the metallic rods inside the tank that helps reduce corrosion will be bigger.

You can find more information on what other things you will need to know, like what the first hour rating is, or FHR, and how it is used to determine water usage. While a 50 gallon water heater may suit your needs now, you may want a bigger or smaller one after the warranty has expired, usually in about 10-12 years, depending on if you have hard water or not.

Water heating is a thermodynamic process that utilizes sources of energy to heat water above its normal temperature. Hot water is usually in very high demand in most homes for purposes of cooking, cleaning, and bathing. Using hot water for industrial applications is also common practice. Heating water at home has for a long time been done in water heaters such as kettles, which cannot provide a constant supply of hot water. The need for a constant hot water supply has brought to the use of relatively larger water heating appliances otherwise known as boilers to the forefront.

Water heaters are available in various types and sizes. The most common are the tank water heaters, designed to store water and utilize energy from sources such as electricity, geothermal and others to heat the water. These water heaters are specifically designed for industrial or commercial purposes and are often found in modestly large capacities. The common water heater sizes in this category include 30, 40, and 50-gallon units, which are the standard sizes. It is also possible to find tanks ranging from 2.5 gallons to 19 gallons.

Tankless water heaters are another type that have the ability to provide instant hot water whenever the need arises. These heaters do not require any storage capacity and can thus come in a variety of sizes. Tankless water heaters are small by design, often the size of a loaf of bread or even a laptop. In fact, the largest tankless water heater is rumored to be the size of a suitcase. Given their tiny size, tankless hot water heaters can actually be mounted on a wall and be operational. This gives them an edge over tank water heaters.

There are certain factors to consider when selecting the appropriate water heater for your needs. Water heater size will be a key element here as it determines the weight of the tank and has a direct bearing on the transport and delivery course. Another factor to consider is the after sales service i.e. how easy is it to access and replace parts. It is also important to look into the efficiency of the water heater and its convenience to use. With these factors in mind, you should easily be able to identify the water heater that satisfies your specifications.

It is equally important for you to be able to pick a water heater of the right size. This may necessitate a visit to the manufacturers’ sites and obtaining an update from the source. Alternatively, chatting up an experienced contractor can give you valuable insight on the size that suits you. When it comes to size, tankless water heating technology seem to have an edge. They have a reputation for being efficient and provide a longer lifespan. Anyone wishing to buy a water heater would do well not just to go looking for affordability, but also the right size that fits well with the space that he or she has for installation.
