Tankless Concepts

Very well. Was accomplished by working a 12 hour day. Minimal impact of water turn off ( a few hours only) and no electrical disruption. Great service in locating new unit in footprint of previous tankless hot water heater which drained into sump pump well. Heat is very efficient and does so much quicker than previous system which had no circulating pump and took up space at opposite end of the cellar. Purchased larger unit (only $200 more) since planning an expansion of one room addition which now has one radiator. Replaced old piping with multple shot off valves in the event another zone needs to be added in the future.

Fantastic! They showed up on time and stayed late to finish a flawless installation in one day, got the hot water and space heat back on, and cleaned up everything before they left. They were back the following morning to make some final adjustments. The price was among the lowest of four bids we got, and other firms estimated the job would take 3 days. The DC plumbing inspector said it was among the neatest installations he has seen. We are more than satisfied.

Everything from Scheduling, Installation Support, there was a problem which was taken care immediately and lastly the overall customer service and quality of installation + county inspection was a pass Great experience Would highly recommend

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 heaters available, the company is really a pleasure to work with. Further, as they are a local company in the Northern Virginia area, I was also very happy to be able to support an awesome local business. Their installation was flawless and I am overjoyed to finally have the tankless system I have wanted for a long time There are many reasons for choosing to install a tankless water heater and if you are considering it or even curious about them, you should do yourself a favor and speak with Tankless Concepts first.

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 used four zones to unevenly heat our 80-year old; 2,300 square foot; 4-bedroom; 3-1/2 baths; house. The new two-zone system, developed from a room-by-room heating analysis of our existing radiators and cast iron baseboards, heats the house evenly. The hot water is endless. As a retired engineer, I was impressed by their detailed technical and product knowledge. They understood and answered all my questions. They developed innovative low-impact cost-effective boiler venting solutions for this old brick colonial. The installation started, proceeded, and completed on the planned schedule and at the agreed cost. There were no surprises. We are reaping substantial savings. With the old equipment, our monthly non-electric energy costs were about $230 a month ($2,760 a year) for the oil-fired boiler and about $25 a month ($300 a year) for gas-fired hot water, cooking, and clothes drying. With the new equipment, we heated the house through the entire 2019-20 heating season for about $600.

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 cleaned up well after the job. They kept me informed on where they would have to cut holes in ceiling to route the vent and it was all as planned earlier. The plumbing job was immaculate with multiple valves installed for convenience. I also loved how the pipes were laid out in a designer fashion. Overall me and my wife are extremely happy with the install and the overall experience. The price was reasonable and comparable to other quotes I received.

Our tank water heater stopped working during the COVID-19 shutdown, and we decided to have it replaced with a tankless heater. 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. The installers arrived on Monday, and the system was installed exactly according to plan, with the job completed in less than 5 hours. They arranged upgrade of the gas meter with Washington Gas (on the same day), removed and disposed of the old tank, arranged for utility rebates, and provided forms to apply for tax credits. The installation was done "contactless" during this pandemic. Everybody was highly responsive and professional.

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 old unit, no mess of any kind left behind. System looks great, working well. Linda Cahill in the main office was particularly helpful throughout. From helping us choose the right equipment, to explaining their bid and keeping the work on schedule, to informing us about rebate options, etc., she is both knowledgeable and a pleasure to work with.

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.

They kept me informed every step of the way he handled all the permits and contacted Washington gas. Other companies wanted me to do the legwork for the same price. The price is reasonable and fair, no surprises.
