[quote=enron_by_the_sea]The main issue of going with tankless is that you will probably need a bigger gas line and better venting than what you have. Which may make the installation more expensive.
Remember that now to install even a tank heater, you need a permit from the city and a visit from an inspector to make sure it is done right. If you end up doing something to the gas line to go tankless, probably another permit/inspection will be required…[/quote]
Yes. Permits are required.
And to answer brian’s question – yes we installed it outside. The big challenge was that it had to be a certain distance from operable windows – so that gases (CO) wouldn’t get into the house. So even an outside installation requires thought about “venting”.
Replacing our old tank, in it’s location, with it’s pipe runs, would have left us with the same problem. If we hadn’t had those issues (hot water pipes going through slab, exceptionally long runs from tank to sink/shower) we probably would have stayed with a tank model.
