We currently have a standard 60 gallon water heater. It is a long run to the bathrooms, so we have a hot water recirculating pump. But my wife likes to take baths in our large tub, and often there is not enough hot water for her to be comfortable - sometimes there's plenty, sometimes hardly any.
Our water heater is about 15 years old, but seems to be operating fine.
Which of these options or upgrades do you recommend, or do you have another suggestion?
1. Turn off the recirculating pump and just live with the long wait for hot water at the business end of the house (seems that wastes a lot of water).
2. Buy a water heater with a larger tank (maybe 90 gallons?)
3. Replace the water heater with an on-demand water heater for the whole house
4. Keep the w/h with the tank but add an in-line, on demand heater just before the two distant bathrooms
5. Add a supplemental water heater with a small tank just before the two distant bathrooms
Those are the options I thought of, maybe there are others. Also, what should I do with the recirculating system in each of these scenarios?
I'd like to get unbiased opinions from the good folks here first. I know local water heater sellers could make suggestions, but I know they'd only recommend whatever products they personally sell, which may or may not be the best solution for me.
All advice will be greatly appreciated!
