you need large supply lines for gas tankless, and do check your

cold.

tankless rarely save much because of their high initial cost, service
requirements, you need local service tech, and the warranty is never
more than 10 years.

newer regular tanks are foam insulated with nearly no standby losses
and very reliable requiring little or no service

if a gas tankless using electricity a power outage means no hot water
at all.........

standard tanks have enough hot water for at least a couple showers..

if you desire endless hot water get a 50 or 75 gallon regular high BTU
TANK. 75,000 BTU IS OVER TWICE a regulat 30K btu tank

regular tanks are pretty cheap tankless cost a fortune and
manufacturers require pro install for valid warranty...


Like most things, there are pros and cons. The biggest pro, IMO, is
the fact that with a correctly sized gas tankless you have unlimited
hot water. And you do save on energy by eliminating standby loss.

The negatives are, for any reasonable whole house use it has to be
gas, as electric would require the entire typical service capacity.
And even with gas, you may need to upgrade the supply lines to meet
the demands, as opposed to just dropping in a replacement std unit.
That combined with the cost of the unit means that it can take a long
time to recover the higher upfront cost.

You just have to decide what is important to you, how long you expect
to live there, etc.
