Awesome company, awesome installation. A forum recommendation lead me to contact Tankless Concepts to discuss an install in late January of this year. The installation was completed in early February, and even an A rating doesn't do the company justice. Impeccable customer service, responsiveness and patience in explaining and discussing the pros and cons of the different models of tankless water ...

GREAT PRODUCT. GREAT PEOPLE. SAVED OVER $2,000 ON HEATING THE FIRST YEAR, We hired Tankless Concepts to replace our oil-fired heating boiler and gas-fired tank-style hot water heater with a gas-fired NAVIEN combination boiler and tankless hot water heater, after meeting with four contractors and reviewing three proposals. We saved over $2,000 on our heating costs the first year. The old system use...

The service was outstanding right from the estimates to completion. The technician who came for the estimated was very knowledgeable and catered to all my questions with detailed responses. I felt very comfortable going with a tankless water heater as I was hugely debating this with the tank water heater. The installation was a breeze as well. The crew came on time, worked independently and cleane...

Tankless Concepts responded within minutes to a voicemail left on Saturday, and a detailed quote was provided based on an extensive phone conversation and photos that I provided, including discussion of anything that could arise unexpectedly.

Excellent overall experience. Tankless Concepts' bid was easily the best (by a couple thousand $$$ on a roughly $5K job). They scheduled the job in a very reasonable timeframe (a couple weeks). All folks I met with - the individual who provided the bid, several on day of install - were very pleasant to work with. Installation was handled efficiently, easily completed in one day, hauled away the ol...

They were very professional and knowledgeable. The company's rep knew exactly what size water heater we needed for the size of our house and explained all the details of their installation process. The day before the installation, they had Washington Gas come and change the regulators on our gas meter to accommodate the larger gas draw for the tankless water heater. The installation went exactly as planned. We had a problem getting our county to pass the installation inspection because the inspector didn't think our gas pipes were large enough for the high end gas draw when the unit was at max capacity. Tankless Concepts took care of contacting the head of the plumbing inspectors and arranging for him to do the 2nd inspection. One of the company's owners was here when the inspector arrived, explained how the unit worked and demonstrated that our current gas lines were adequate to power the new water heater. We passed with flying colors on the 2nd inspection. We highly recommend this company if you're looking to purchase a tankless water. heater.
