"Boiler broke down this week. Matty was first to respond. Told me would see me next day & he did. On time, literally, disciplined, caring & very clear in communicating expectations. He listens then tells you pros and cons. Although very busy, you do not feel shortchanged if he needs to run to another emergency. He makes sure to be the first one to arrive, sets up his crew (excellent crew too), tells them exactly what & how he wants things done, & patient answering probably redundant questions. He is fair in pricing & gives good advice. His crew is skilled, quiet and fast. Do more than what is expected. In my case, they secured loose pipes, replaced pieces that were old, & even bought a dead radiator back to life (had not worked in years). Doc, the electrician wrapped things afterwards. Very thorough & organized and again, arrived when he said he would. The place was left clean and all debris & boiler was taken by them. I hit the lotto with Matty, one in a million!"

"Let me start by saying they fixed my leak, cleaned up after himself, were available to start when I needed them, and did not leave any open areas. They quoted me a price to fix a water leak in between my first and second floor bathrooms. Tony quoted me $3800 (I only had $3600) saying this was a big job after he cut a 1ft 6in hole in my 1st floor bathroom ceiling to see what is going on. He said he had to also remove the 2nd floor toilet and create another hole to work through both floors (him and his partner) to access the leak. He called his partner in and by the time it was completed they did not even remove the 2nd floor toilet - which is why I agreed to the higher price because I was led to believe it was more labor intensive."

Tankless water heater installations FAQs

Yes, although they have a higher upfront cost compared to traditional units, tankless water heaters can be worth the investment for many homeowners. They heat water on demand, eliminating standby energy losses and leading to 24% to 34% greater energy efficiency for homes using up to 41 gallons of hot water daily. Tankless units last longer—around 20 years with proper maintenance—and require less space than traditional units. They also reduce the risk of leaks and water damage since there's no tank to corrode and fail.

Tankless water heaters, including gas-powered models, do require electricity to operate components like the ignition and control systems. This means they won't function during a power outage. If you live in an area prone to outages and want to ensure a continuous hot water supply, consider installing a battery backup system or generator to keep your tankless water heater running when the power goes out.

You should set your tankless water heater to 120 degrees Fahrenheit for optimal safety and efficiency, as recommended by the U.S. Consumer Product Safety Commission. Setting the temperature at 120 degrees prevents scalding accidents, particularly for children and the elderly, and reduces energy consumption. Temperatures above 140 degrees increase the risk of burns and promote mineral buildup, which can decrease the system's efficiency.

A 20-minute shower uses 50 to 60 gallons of water, assuming a flow rate of 2.5 to 3 gallons per minute. A typical whole-house tankless water heater can produce 4 to 8 gallons of hot water per minute, providing continuous hot water for long showers. By installing low-flow showerheads and reducing shower time, you decrease water consumption and energy costs, maximizing the efficiency of your tankless system.

With proper maintenance, a tankless water heater lasts around 20 years, significantly longer than conventional tank water heaters, which last between 8 and 12 years. Regular inspections and timely repairs can further extend its lifespan. To keep your tankless system operating efficiently, have it inspected or serviced annually and address any minor issues promptly by contacting a local tankless water heater repair service.
