Water Heaters
We install conventional hot water heaters and service them to keep them functioning at their best.
We also specialize in the installation and service of Navien tankless water heaters. Navien uses advanced technology that allows water to be heated on demand. Tankless water heaters never run out of hot water, save money on energy bills, and have a much longer life span than traditional water heaters. They are wall-mounted, which saves space, and are environmentally friendly.
Lawrence Plumbing LLC is one of just a few Knoxville area companies certified to service and install Navien products; proudly maintaining a Navien NSS certification.

Testimonials
“We have been happy customers of Lawrence Plumbing for several years. Two years ago, we replaced our aging water heaters with two new Navien tankless units. We absolutely love them. They instantly provide an endless supply of hot water for our large family and even when we have multiple guests staying with us, they meet the demand every time. Lawrence gave us great advice, a great price, and exceptional service during the installation process. Two years later, we couldn’t be more satisfied with our purchase.”
– Mike & Ashley Baisley
“Lawrence Plumbing made the installation process and transition from a tank water heater to a Navien tankless very smooth. We have been very happy with the performance of tankless and it has been a big help to our family. With 3 dirty boys, lots of sports. and lots of showers- We could not be happier!”
