Valenta Plumbing sells, installs, and services Navien premium condensing tankless gas hot water systems. We sold and installed several other brands before focusing exclusively on Navien brand products. Navien has earned our trust and support—they are simply the best tankless hot water system on the market.

“I believe in doing thorough, real-world tests on every product we sell. Valenta Plumbing tested two other tankless water systems prior to trying Navien. We were dissatisified with all previous products. Navien is by far and away the best tankless hot water system on the market—with an unmatched 15 year warranty on its stainless steel heat exchanger, and 5 year parts warranty.”

The ultimate in energy efficiency

Navien condensing technology provides up to 0.99 Energy Factor. These extremely efficient and eco-friendly units provide extra energy savings over traditional tank and non-condensing tankless water heaters.

A cooler way to save energy

Navien’s primary condensing stainless steel heat exchangers recover extra heat that would be lost in non-condensing tankless heaters. That keeps exhaust temperatures very low—so low that economical Schedule 40 PVC pipe can be used for venting in almost all applications.

Navien condensing tankless water heaters are ideal for replacement of less efficient tank systems as well as for new construction.

Go Green! Better for You, Better for the Environment

Navien utilizes an ultra-efficient condensing technology, which uses less gas resulting in a significant reduction of green gas emissions—better for you, better for the environment.
