you two can debate this till hell freezes over....
What do you charge to de-lime tankless heaters?? once a year $175.00 ....$250???
if you dont factor in the mandatory maintaince then you are simply
lieing to the customer about payback... just to get them to go tankless
that is called .........greed......... you blind yourself to the facts and mis-inform
the customer just to get to make some big bucks and then you walk away
then 8 months pass and they call you and you say oooppps I forgot to tell you
that you need to de-lime these things every so often........
the average return on the investment works out to about
22 years...consumer reports 08.. that is with a saveings of
a massive $80 bucks a year over a normal tank type heater..
wow, 80 bucks , I want to run out and get one right now.....
read it for yourself..
you must factor in the de-limeing service that MUST be
done at least once a year or sometimes TWICE...in Indiana...
are you planning on going out for the next 22 years for FREE to do this??
What do you plan to charge the customer to DE_LIME
their tankless unit each year??? Does $175.00. sound fair???
basically...if the customer does not do their own maintaince
on these units their really is no saveings at all..
their is actually a huge loss over a tank type heater.. :yes::yes::yes:
now once the tax credits end........
the fat lady sings like a songbird............
One can find infinite literature/reports for or against tankless. And as was pointed out the return can be manipulated for or against the actual return as well. So I wont argue those points. But I will say that most of the ones Ive installed, the owner did not buy based on the return.(Does one buy a Ferrari based on a return?)It was more for the fact that they will never run out of hot water and will never have to replace the unit. And the wives loved the extra space that was cleared by getting rid of old tank.
As for the descaling, there are several ways to handle that.
* Charge X amount per year as most have pointed out. (A gross waist of money for the owner indeed).
* Install a point of use descaler (Noritz has their own or you can use any other). 1 or 2 de-scalings would pay for it.
* Install a softener. X per year forever to descale or X one time only and have the benefit of a new softener.
* Include the descaling in your annual maintenance plan (if you offer this service) just as you would include flushing the tank water heater.
Or plan B: Stand back and watch, clearing the way for those who do offer them.:jester:
