Need more hot water for whirlpool. What are the options?
Posted by Bob A on January 13, 2004 at 13:01:25:
I just installed a new large whirlpool/shower and the 50 gallon gas water heater we now have is insufficient (by a lot).
What would you recommend and why? If you know the relative cost, that would be helpful, too.

We are considering the following
1. get rid of old water heater and replace with new 80/100 gallon gas water heater
2. get a tankless gas water heater to supplement the existing heater
3. get a tankless electric water heater to supplement the existing heater (this may not be possible since we a currently just about maxxed out on our electric)
4. get a second 50 gallon gas water heater.

As far as the tankless options go, we would either connect directly to exising heater (either between the existing heater and the outside main, or between the tub and the existing heater), or operate as a separate dedicated water supply to the whirlpool.

Thanks for any information.
