GAS TANKLESS WATER HEATERS



WHOLE HOUSE High Performance GAS Tankless HOT Water Heaters

Top Gas Tankless Water Heater Reviews

By heating water only when it’s needed, our powerful gas tankless water heaters cut water heating expenses, while providing continuous hot water delivery.
Instead of maintaining a tank full of hot water at all times, tankless gas water heaters achieve greater efficiency than standard traditional tank-type water heaters.
They really do save energy by heating water only when needed, eliminating energy lost during stand-by operation.

Gas tankless are becoming popular as a replacement for gas storage water heaters and a great choice for new construction and remodeling.


HOW Does a GAS TANKLESS Water Heater WORKS?!
Here is how a Whole House Gas Tankless Water Heater works

Whole house gas tankless water heaters apply the same principle to heat water as standard gas water heaters, but without a storage tank.
The tankless gas heats water as it flows through the tubing in the heat exchanger inside the heater.

When you open a faucet or turn on the shower, instant command for hot water tap is turned on in the home, cold water is drawn into the water heater, a sensor detects water flow and activates the gas burner which warms and heats up the heat exchanger, hot water is instantly brought in within seconds…and keep on flowing continuously.
That incoming cold water encircles the heat exchanger and leaves the heater at its set-point temperature, combustion gases safely exit through a dedicated, sealed vent system.

With traditional tank type water heaters, you have hot water until the hot water tank’s supply is depleted, then you must wait for the storage tank of cold water to re-heat before you again have hot water.
But with a tankless hot water heater, the time it takes for hot water to arrive at the tap is done immediately, a real on-demand switch command : as soon as the faucet is turned on, hot water is delivered : instantly, efficiently, and continuously … until you turn off the faucet.
The best thing about the hot water that comes from a tankless model is that you will receive an endless supply of hot water for as long as the faucet is being turned on.

USEFUL INFO ABOUT THE NATURAL GAS UNITS VENTING SYSTEM

Exhaust ___ Direct Vent ___ B-Vent ___ Z-Vent ___ Pipe Lines ___ Flue

The proper venting Materials and procedure for the venting of the Natural Rise Power Gas Series are as followed :

The preferred material for these heaters is B-Vent which means : doubled walled, galvanized metal outside, polished aluminum inside.
The GA5 and GA10 both require 4” venting and the GA16 requires 5”, but the supplied adapter may be used to go up to 6” (Never reduce in size).

You must establish an 18” collar rise before installing any bends or condensation catches.
Never install a 90 degree bend directly on top of the heater.

The minimum height allowed is 6 feet, this is to allow enough pipe to heat up to properly vent the gases and moisture from combustion.
A straight vertical run is preferable.

IF horizontal runs are necessary then they must always be sloped up at least .25” for every foot and must be kept shorter than 75% of the total vertical length.
Never terminate the venting horizontally, you need the last bit of vertical run to “pull” the remaining gasses that may have cooled in the horizontal run.
Many municipalities require a “chase” to be added up to the roof line for any venting running up an exterior side wall of a structure.
Please check local guidelines.

IF venting through the roof then the termination height will depend on your roof pitch.
IF condensation is a concern for a specific installation then other more specialized materials should be used most common is Z-Vent (double walled stainless steel on both in and outside layers).

IF there are any deviations from these guidelines then please seek the help of a qualified HVAC technician.
Improper venting is risky, could be hazardous, dangerous.

Question: What size is the Flue pipe on the power natural gas and propane units and do they come with a through the wall kit?
ANSWER: The vent pipe for the gas tankless units is 4 inches. ALL units come with a Stainless Steel Chimney adapter piece.
