Direct Water Heater Vs Indirect

Powerful high amounts of heat btu s are produced in smaller units when compared to indirect fire heaters.

Direct water heater vs indirect. These types of water heaters are traditionally the most energy efficient. This increases the chance of heat losses in the boiler and associated pipework between the boiler and calorifier. Indirect heaters balance this by having fewer parts exposed to the naturally corrosive elements found in the tank water and no independent energy cost. Standard direct water heaters don t need to transport water over a distance so in one regard they can be seen as more efficient.

The heat exchanger coil inside the heater then uses the heat from the boiler water for its heating. They are more energy efficient than an indirect water heater because it heats the water itself. Indirect fired heaters. Overall indirect water heaters have been around for decades and are much more easy to use.

Direct fired water heaters are solely dedicated to the job of hot water generation providing a faster heat up and response time compared with an indirect system which is in fact heating water to heat water. Direct fired heaters are both more efficient and less expensive than indirect fired heaters. Conventional heaters are only about 50 efficient. Indirect fired water heaters vs conventional water heaters.

Direct water supply systems demand huge pressure because high capacity pumps are required to facilitate the reach of water to the upper storeys. Here are the core benefits or features of the heater. However indirect heaters are more efficient in other ways. Let s compare an indirect fired water heater to a separate gas fired water heater and boiler combination.

Additionally with indirect water heaters you would not have to worry about maintaining a stand alone heating system which would involve flushing the tubes and cleaning the heating coil to say the least. The two most common sources are direct and indirect fired heaters. Easy to transport direct fired heaters are fairly simple pieces of equipment that can be moved to where heat is needed. Some units do not require electricity.

Lower rental costs direct fired heaters are less expensive. Whereas for indirect water supply systems even moderate pressure will suffice as here water needs to be supplied only at the ground level. A direct fired water heater can be heated by propane oil or natural gas and has its own burner. In other words for every 100 spent on gas for the water heater 50 goes out through the chimney.

In other words indirect water heaters work with the existing boiler or furnace in your home to supply domestic hot water.
