Rinnai Tankless Water Heaters

 You don't have to worry about running out of hot water again. Our innovative technology provides an endless supply of hot water whenever and wherever it’s needed – even for simultaneous uses at multiple fixtures. Back-to-back showers and baths? Absolutely. Laundry and dishes at the same time? No problem. Prioritizing activities and scheduling hot water use is a thing of the past. Designed for efficiency: Rinnai’s tankless technology features durable heat exchangers to provide maximum efficiency and uses up to 40 percent less energy* than a traditional tank.

By operating only when hot water is needed, with pilot light and no storage tank to heat and reheat water, our tankless technology helps save on energy and utility costs. The use of an electronic ignition means no standing pilot light that constantly uses energy.

Our Customers Are Our Most Important Investment.


  • "We have dealt with Clay at Southern Hearth and Patio for many years.  He and his staff have always been very helpful when we built our house for fireplaces, furniture, and our beloved Primo smoker. They always have the latest trends and quality products and our first go to when we need something new. Great place to go browse with no hassle or pressure. Will always be a repeat customer." - Michael D. Chattanooga, Tn. 
  • "I am a general contractor and have always appreciated the professional help given by Southern Hearth & Patio. Clay has always provided great products at a reasonable price. I would recommend any of my customers (and do) to Southern Hearth & Patio." - Tony H. Chattanooga, Tn.
  • "I have had multiple opportunities do business with Clay and Charlotte at Southern Hearth and Patio. Gas log purchase and installation were completed with ultimate professionalism. Service staff is very knowledgeable and helpful. My purchase of a pellet smoker is so much better than I thought it would be. Glad I listened to Clay as I have had many great meals. I also love the showroom as I am like a kid in a candy store. I can't imagine that anyone can do it better than Southern Hearth and Patio. I will no doubt be back again." - Randy B. Soddy Daisy, Tn. 
  • "Clay and Charlotte Dennis have proven once again that a great family business with happy, well trained employees will succeed. Their products, knowledge, service and showroom are "top shelf". Simply put, at Southern Hearth and Patio, they are "the best" at what they do." -Joel S. Chattanooga, Tn.
  • "Southern Hearth and Patio has tremendous knowledge with everything that has FIRE involved. From wood burning and gas fireplaces to wood burning and gas grills. Each and every employee can be called experts in their field. As an added bonus most if not all products sold by Southern Hearth and Patio are MADE IN THE U.S.A. Can not go wrong buying any products from Clay and his family." - Lenny D. Chattanooga, Tn.
  • "In the search for a high quality BBQ grill, I ended up at SH&P. I appreciated getting greeted when I entered but given the space to look around and take it all in. The showroom is impressive! I don't mind paying premium money for premium products and after I received accurate information regarding the Fire Magic grill, my perspective switched from "premium" to value! Clay and his staff are great! Their product selection was a little to good because I left with a Yoder Smoker also. 6 weeks later I could not be more happy with my purchases. I did well on a grill before, but the Fire Magic takes it to another level. The smoker makes me look like I have years of experience, it performs flawlessly. I had one issue with my grill and Clay's service technician fixed it the next day and I live in Cleveland, TN. Under warranty of course. That type of service is nearly a thing in past except for SH&P!" - Warren D. Cleveland, Tn.
