Seminole, I heartily agree with you about Lowe's...never did like them and they are more expensive than Menards. I find it user friendly when I go to Menards. You know, how guys are, partial to their favorite home improvement stores. Usually I shop at Menards more than I do with Lowe's.
My sis got a tankless heater and LOVES it. When I look at the set up and asked my Dad about installations, he said it is very simple and easy to do when you have a little knowledge of plumping and gas lines. No special treatments needed and he was perplexious about the employees at Lowe's about lining the chimney and so forth...sounded like a rip off but no use telling hubby that!
I am hoping in near future, we will get a tankless heater.
