      IMHO

      The good thing about tankless heaters less stand by losses but less peak demand also as far as lots of volume is concerned.

      The bad thing about gas water heaters is when they fail they leak all over the place.

      They have lots of stand by losses and take up a lot of space.

      The best manufacturer is the ones that don’t fail as most of the imported stuff today is PURE GARBAGE and border line dangerous.

      You could try to get Canadian brand rather then one imported by an “American company” from God knows what part of the planet.

      Canadian standards are now the ones to go by if your looking for Quality.

      To many American code bodies have been compromised by the almighty YEN to line their pockets.

      Think about why would any code official allow an AAV to be placed inside a home?

      Putting their trust on a piece of plastic and rubber to keep dangerous sewer fumes out.

      Ah the Almighty pay off we see on TV is not all fiction I guess.

      Do some home work before buying and do your very best to keep away from American IMPORTED crap flooding the market place.

      Good luck

      Check out Takagi, they have most recently come out with a larger unit that claims to deliver 7 gallons of 120F a minute. The technology is getting better all the time. http://www.Takagi-USA.com it seems as if this site is under construction. E-mail Marcelo Martinez at marcelo@takagi-usa.com or call 949-453-8388 for additional information.

      A 7 GPM heater is a true wonder. That calculates out to an appliance that uses a 300,000 btuh gas or electric input. Now let’s figure how far the gas line has to go to get to the heater and if the gas line in the house is large enough to carry this input and still supply the other appliances. Same with an electric input of 75 kw to do the same.

      Considering that the major draws are 1-1/2 hours in the morning or 2 hours at night, the unit sits there ready to do the duty of a commercial boiler in a factory for the little home. The unit has nice little coils of tubing to become restricted with lime in a short while; then the unit burns up or refuses to work. These units are serviced by rebuilding them every year in Europe and Japan, but not on the North American continent.

      A standard 75 gallon water heater can have a 40,000 btuh input to do the same 7 gpm flow that a home needs, with proven neglect.
