|In response to Re: Need more hot water for whirlpool. What are the options?|
: I'm not a plumber or other expert, but we did install a whirlpool tub during our remodel last year. We had a similar problem, and considered some of the same options, including installing a separate water heater just for the master bath.
: We found, however, that running only the hot water at the beginning until we can turn the jets on, and letting the inline heater on the tub keep the temperature steady while the rest of the tub fills works pretty well. The tub heater measures the temperature of the water when you turn it on, and then keeps it at that temperature. Once the heater is going, it doesn't matter if the hot water runs out. Just make sure you have the tub at the temperature you want when you turn the jets on.
: The inline heater can be purchased separately for about $150 or so, plugs into a regular outlet, and installs in about 2 minutes on many tubs.
: Maybe one of the experts here can comment more on efficiency and how it would compare to other alternatives. It works for us, it might work for you too.
: : We'll let the crew ring in on this one as you have a lot of ?s.
: : The electric tankless heater is very expensive to operate and consumes a lot of power from (on avg.) 240V 30 amps on up to 120+ amps depending on capacity such as dual tank multiple elements, etc. You could have anywhere from one double pole 30 amp on up to 2 Double Pole 60 amps (breakers) or more.
: : Other than the smallest (double pole 30), if you have other 240 volt appliances such as range, dryer, etc., you "might" be able to get away with one double pole 60 amps tops. If you have electric heat, forget it. [Assuming 200 amp residential service]
: : An electrician can advise you, but the cost to use is expensive. The benefit is that the water does not sit around and cool down. You are using current only when you use water.
: : P.S. What is your current WH temp set at?
: : Some homes can get by with 50 gallons for one whirlpool. Although that takes most (if not all) of it.
: : That's my turn, who's next?
: : : We are considering the following
: : : 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.
