We will try to cover all the above factors in our review and present you an easy to understand guide, so you can find the best heater for your needs, such as the selection of the best models as found in this article.
Gas heaters can use both natural gas and propane gas or LP. Gas appliances are a good choice where this energy is available and since these are among the most energy-efficient systems - particularly those with the condensing technology. You can choose between tank and tankless models - water heater reviews cover them both. To know how much hot water it can be produced, look at the heaters' specification and the gas input given in BTU per hour.
Electric water heaters are recommended if electricity is the only option. Even with the higher energy factor than gas burning units, and due to the higher rates, using the electric unit is more expensive in the long run. They are a good solution as the point-of-use heaters for small jobs and heat pumps where the high energy factor offsets higher fuel costs.
Solar water heaters have a simple design that can be made at home where the solar energy, used for water heating is free. In the long run, using this renewable and cost-free energy, solar heaters can be a great lifelong investment.
Oil-fired units are becoming less-popular systems for residential, home usage, especially with the increased availability of gas and other "green" technology systems. Oil-fired models are also more expensive to install than gas and they last less.
Wood fired heaters and wood furnaces are the heating appliances that are using wood as the energy source, for cooking, home heating, and water preparation.
Tankless, usually called on-demand water heaters, do not utilize a water storage tank as the conventional type. This type heats water when needed (on demand) and provides hot water in endless supply while reducing energy consumption and the heating bill at the same time. It lasts longer than conventional storage tank heater and is more environment-friendly due to the reduced gas emission.
Water tank heaters for home use are the most popular of all heating systems. Hot water is always ready for usage, and even if you are away, the heater is keeping the hot water available.
Electric heat pump water heater is the system that utilizes a technology for an efficient and inexpensive heating, using electricity to extract the heat from the air and move the heat from one place to another.
High-efficiency units are very popular today due to its ability to maximize the energy savings, provide better performance and reduce the emission. These products are often Energy Star approved carrying the blue tag logo, an international symbol for energy efficiency, on the casing.
Water heater reviews also cover state-of-the-art appliances such as the ultra-efficient condensing models.
Condensing appliances are energy efficient systems that are designed to provide an efficiency of over 90 % and at the same time very low energy loss. Due to its advanced condensing technology, required professional installation and regular service, these are found more expensive than non-condensing units. They are especially popular in Europe (Vaillant, Buderus, Junkers), while in North America are getting in popularity (Rinnai, Noritz, Navien, Bosch).
RV water heaters are designed for mobile and recreational vehicles, mainly using propane gas and 120 V AC. The most common sizes are 6-gallon and 10-gallon tanks. These units are easy to operate, maintain, are reliable and can last longer. The most popular brands are Atwood and Suburban.
Portable hot water heater provides the perfect solution for heating the water for outdoor activities like camping, hiking, boating, fishing, hunting, surfing, boating, cabin owners and RVing.
If you already have a furnace or boiler with a burner, just combining it with a high-efficient storage tank, you can have a very efficient system for heating. These systems are usually called indirect hot water heaters.
Direct vent water heaters are ideal if planning a gas unit but don't have a proper ventilation to the outside, through the chimney. It has a built-in venting system that brings the air in and forces the fumes out, but without using the electric blower.
Power vent unit is similar to the direct vent models, but it uses an electrically operated powered vent (blower) as an assistance to mechanically exhaust the combustion gases to the outside.
Tankless coil doesn't use any storage tank for the heating as the water is heated directly inside the boiler. It is used for home space heating and with an option to heat the water. These units are the most efficient during the colder months when used for space heating, but less efficient during warmer months as the boiler is used less frequently.
Reviews of the top marine hot water heaters manufacturers, like Atwood, Isotemp, Webasto, Torrid, and others. Products are meant for boaters and sailors to enjoy showering and small jobs where hot water is needed.
Point of use water heater is a small heater, designed as the mini storage tank or tankless unit, used for water heating at the point of service, often installed under the kitchen sink. Also known as under-sink water heaters, these heating units are very popular in residential applications as they provide instant hot water, without taking up a lot of space.
