Advice needed! water heater dying soon before renovation
Renovation starting soon of bathroom and kitchen (contractors bidding now). I've been considering having Rinnai on-demand heater instead of standard one but haven't researched things like what people here say about putting in something so heat to certain places is immediate. I've upped the temperature and still lukewarm.
Advice re: getting in plumber to see about repairing this one -- is that even worth trying?, replacing w/o much or any research with on-demand, replacing with traditional.
