Why Buy Gas Tankless Water Heaters?

Gas Tankless Water Heaters provide an unlimited amount of hot water at the lower possible price.

Here is how Gas Tankless Water Heaters work. When there is demand for hot water, cold water coming from the main supply pipe of the building, travels through a pipe into the unit and a gas burner heats the water. The fact that there is no tank means that there are no standby energy losses as there is no need to keep the water in the tank at the desired temperature all day long. Instead, water is heated only when needed and on top of that, there is no limit to the amount of hot water you will be getting as there is no tank. With conventional water heaters, you get as much hot water as the tank can contain.

The biggest advantage of gas water heaters is that the price of gas is lower than electricity so you will gain the biggest possible savings. It's estimated that the cost of gas is approximately one-third that of electricity on a per-Btu basis. Gas tankless systems also have wider applications because they produce hot water at higher flow rates.

In the case of gas tankless water heaters, two types of gas can be used - propane and natural gas. Propane and natural gas are available in many areas of the United States to fuel conventional storage and demand (tankless or instantaneous) water heaters, as well as combination water and space heating systems, which include tankless coil and indirect water heaters.

Of course, installation of gas tankless water heater depends on the availability of an adequate gas source, whether it's natural gas or propane. The price of gas tankless water heaters ranges from $1,000 to $1,200 or more for reputable brand. Have in mind that venting requirements make installation very expensive, hence extending payback period on investment. The problem is that gas tankless water heaters have complex venting and combustion air supply requirements. The flow rate can be up to 8 GPM or more in warm climates. Compared to propane, natural gas is slightly cheaper to operate, but natural gas prices are projected to rise dramatically in future, and tankless is a long-term investment (20 years or more).

Currently, an electric tankless water heater is about 10-15% more expensive to operate than a natural gas tankless heater. A tankless electric heater is generally cheaper than a propane tankless heater.
