Tankless Water Heaters

Thornton & Grooms is proud to offer Michigan residents state-of-the-art brands like Navien Navien® Tankless Water Heaters. 

Hot Water…Only When You Need It!

Navien's Condensing tankless water heaters can provide you with an endless supply of hot water, providing hot water on demand. Navien achieves this by activating the unit the second you open a hot water tap. Conventional tank-type water heaters eventually run out of hot water when you take multiple draws in a row from the tank. Since Navien Condensing tankless water heaters only provide hot water when you need it and can provide an endless supply of hot water, you never have to worry about running out of hot water no matter how many hot water draws you have in a row.

Why Condensing Technology?

To help explain "condensing technology," imagine the condensation on a glass of ice water. This condensation is created inside Navien's condensing heat exchanger (secondary heat exchanger) from the incoming cold water cooling the hot gases inside the unit. Navien's state-of-the-art, stainless-steel condensing heat exchanger then traps this condensation and uses it, making the whole process incredibly efficient and economical.

This condensation (or vapors and gases) would normally escape through the vents in a conventional tankless water heater. But with Navien's cutting-edge technology, these water heaters reuse the condensation, providing you with the most efficient and economical water heater on the market today.

Tankless Water Heater - Condensing Technology

Condensing technology effectively utilizes heat that would otherwise be lost, for an unmatched 98% heating efficiency. Its energy consumption and utility bill savings surpass both conventional tank water heaters and non-condensing tankless systems alike.  Knocking the competition out of the water, these extremely efficient and eco-friendly units will provide extra savings for you and your family.

Endless Hot Water. Without the Tank. Without the Cost.

Customer Review
“I was very impressed with my Thornton & Grooms plumber. He was on time, understanding of my concerns, and patient when answering all of my questions. He had the new water heater operating within a few hours, and left no mess after the job was done.” - Steve
