Large hot water boilers or tanks are renowned for causing headaches for homeowners and property managers. The threat of a water leak is ever-present, with many boilers and hot water tanks using natural gas to heat water, thus raising the risk of a gas leak, which could potentially lead to an explosion. Hot water heaters and boilers also need to be kept insulated, as pre-heated water slowly returns to room temperature if not “consumed”, wasting prodigious amounts of non-renewable energy sources.
Tankless water heating systems do not waste time heating water that won’t be used, instead providing homeowners and property managers with on-the-fly water heating to dramatically reduce energy loss and wastage.

While Europe has been using tankless water heating systems for decades, this energy-saving advanced system for providing on-demand hot water is becoming increasing popular across the United States. Without any large boiler or hot water tank to worry about leaking, a tankless water heating system provides hot water instantaneously, exactly when it is needed. Standard cold water entering the house can be rapidly heated to a desired temperature on the fly, allowing homeowners and property managers to only pay for the hot water that they actually use.
Many Americans are used to the sight of a large, ugly water heater tank or boiler in their basement or garage. Connected to the gas main, it is a constant threat that could leak fumes or water at any time. Big exterior hot water tanks use tremendous amounts of energy heating water that isn’t used, wasting energy when there’s no demand for it. A tankless water heating system works by applying a very high source of heat to normal cold water as it enters the house, heating water on the spot.
Just as the gas or electric burner on a stove can be used to heat water, a tankless water heating uses a power source to quickly and efficiently heat water to a specified temperature.
What are the different types of Tankless Water Heaters?
Some tankless water heating systems rely on propane or other gases to heat water, while other tankless water heating systems are powered via an electrical outlet in the home. A modern tankless water system is easily equipped to heat water on demand to provide sufficient hot water for a shower or operating a dishwasher, washing machine or other home appliance that requires heated water.
Other systems are more powerful, providing enough hot water on the fly to allow for multiple showers or other high-use demands on the system, while other tankless systems are less powerful and are meant to be used in an auxiliary capacity. Many tankless water systems are designed to be used to boost or aid other water heating systems, including solar, wind-powered and other “off-the-grid” renewable energy sources.
What are the advantages of owning a Tankless Water Heater?
Not only are big hot water tanks and boilers a hazard, prone to leaking gas or water or potentially even exploding, but they also take up a lot of space. The so-called “footprint” of a hot water boiler or tank is usually quite large, as nothing can be kept in close proximity to a hot water boiler or tank. These systems, on the other hand, don’t take up much space as there’s no need to store large volumes of pre-heated water. Homeowners and property managers can discretely mount tankless water heating systems wherever there is a need, including in outbuildings or other structures not connected to main lines.
With a safe and reliable source of energy, and a much smaller “footprint” in the home, tankless water heaters are a tremendous benefit over older, traditional-style big hot water tanks. Since tankless water heating systems only consume energy when hot water is needed, they save homeowners and property managers in the long term by not wasting precious energy resources to heat water when there is no demand for it.
