What is the typical cost of buying the equipment and installation of tankless ‘Gas’ water heater? For my house we need 2 of them.
My house is being constructed right now, so I asked my builder to put this instead of regular tank. They are charging $2500 for each unit. I think this is too high and payback time will also be long. Am I right?
Also, any idea about cost of installing hot water circulation system to conserve water. Push of a button will bring the hot water within a minute to the faucet.
Thanks You!
Thanks Eric.
What will be the payback period if I’m replacing tank one with this Tankless Gas Hot water system? If I save $20 a month, then it is more than 10yrs. Seems not worth it. What you guys think.

The cost of a tankless unit is about double that of a conventional unit, and you need extra pieces such as a surge tank. The circulation system, is self-defeating with a tankless water heater. That is my opinion, your contractor should be your guide. If in doubt, get a second opinion from another local plumbing contractor. Rather than a circulatory system, consider a filtration or softener system to extend the life of your new system.

2500 is an average price for a tank-less water heater installed.
On most manufactures adding a recirculating system takes the warranty from 10 years to 3 years. In addition the re-circ. system will cause early wear and tear on your copper pipes unless an aqua-stat and timer are used.

You are mixing apples and oranges.
A tankless gas HWH will cost about $2500 installed but there should be a credit from the unit they are not installing, since you paid for it in the cost of the house.
DO NOT add a circulation loop as this will defeat the gas savings of the Tankless system by causing it to run all the time to heat the circulating water.
Think not of the ROI think of the endless hot water.

Ed Z has got the low down for you, but recirculating loops are beneficial if the recirculation is pumped to you roof and heated via the sun. I have this system and i heat the water less than before average annual savings 2 adults 2 teenager and 1 child household natural gas cost 37%
