At least for now, they are trying to keep up with the private labeled Japanese units and they are participating in the market. However, the battle lines have been drawn and it is going to be very interesting for those of us watching this market develop. Party Lines! Pioneers! Rural Companies! In fact, many times it makes sense to move the location of the heater closer to an outside wall and run the water lines to it rather than run longer venting. Next generation wall phone manufactured by Automatic Electric in Brockville. Tankless water heaters can have their venting go either out a side wall with horizontal venting or up through the roof. As long as the velocity of the water is acceptable most people are quite happy and of course some showerheads are better than others. This is not a big problem though and rarely causes issues with the better tankless water heaters. An easy way to do this is to use a tankless water heater valve set like the EXP made by Webstone. If you can run the proper vent product up through an existing chimney to the outlet and provide the proper condensate drain to protect the unit, you can use the existing chimney as a "chase" to run your new vent pipe in.

Do not assume that if your existing gas line is the same size as the connection to your tankless heater that your pipe is large enough. Some will print more than others will but it is all for the same reason. This can be a product like CLR or a vinegar/water solution of one of the commercially available cleaners that boiler companies use to do the same thing with tankless coils in boilers. This one pipe kit saves about 16 joints at the heater! Every foot of pipe and each fitting in the water main has a pressure loss. Another reason this vent is required is that the vent systems are under pressure from the fan within the heater. Type "B" gas vent can not be used on most of these heaters for this reason.

This also may give you a reason to get some needed space back within the home.

This is known as "Positive Pressure" venting and requires that the vent system be UL listed as positive pressure and sealed to prevent carbon monoxide from leaking out into the occupied space. This is due to system pressure loses. All tankless heaters need a minimum flow rate and pressure to work properly. Even with a minimum flow rate of .5 GPM it is possible to have a flow related problem but it is a lot easier to solve. That is about as high a minimum flow rate as you would want in a home. This is why I advise to not use tankless water heaters with high minimum flow rates in homes. What tank manufacturers don't want you to know is it effects ALL water heaters. The heat exchanger is the main part, much like the tank in a tank water hater. The condensate in the venting will destroy the heat exchanger if allowed to run back to the unit. The least of these is the unit may fail very soon in its life span due to condensate being allowed to enter the product. It is also not allowed to tie these vents together or tie them into an existing masonry chimney.

The condensing gasses would quickly begin to cause damage to the masonry and result in structural damage to the property as well as a very unsafe condition with carbon monoxide. At far ends of the home these add up and can cause lower flow rates at fixtures like showerheads. Commercial units can have minimum flow rates of .75GPM . Most homes requiring these units (Large luxury homes with "carwash" shower systems) do not have very low flow fixtures and typically do not need to worry about minimum flow rates. Also, debris in faucet aerators and showerheads can cut their flow rates down to a point that will keep the tankless from firing. Most 2.5 GPM showerheads will not supply 2.5GPM of flow in a new home. Most people never know the difference and as stated above, it is almost impossible for most people, even plumbers to tell the difference between 1.5GPM and 2.5 GPM in today's showerheads without measuring the flow. Even the ones with their "private labeled" products! When these products have to go to high fire to meet a large demand you must be able to provide enough gas for the unit to function properly.
