Our distinction is the quality of service we bring to our customers. Accurate knowledge of our trade combined with ability is what makes us true professionals. Above all, we are watchful of our customers' interests, and make their concerns the basis of our business.

"Ontime Piping And Heating is on TIME and on POINT! I was in an extremely bad situation. I needed a new boiler and hot water heater. Home ownership is new to me, and I had no clue as to where to start. So, I just started googling and I had several so called â expertsâ come by and give me quotes any where from $8,000 to $14,000, and I was told so many different stories. Well, I decided to go on Angi (formerly known as Angieâ s List) and that is how I came across Ontime Piping And Heating. Matty (Matthew Mirabile) walked in and assessed the situation in absolutely no time. He was very professional, knowledgeable and confident. He took his time explaining what was needed and made sure I understood. He made his offer, which was very fair, and I did not feel like he was trying to take me for a loop because I was a woman. By the time he left I knew this was the guy for the job. I even had some one offer to do the job for $500 less, but I decided to stay with Ontime Piping And Heating because I had already given my word and after meeting with Matty I just knew this was the right decision. It was the best decision I made. Matty sent his guys in and handled the entire job in one day. Matty handled every single aspect of the entire process from taking out the old equipment and discarding to purchasing and installing (top quality equipment I must say there were no shorts there) the new equipment to the electrician. It was definitely a team process, and every single member of the team was knowledgeable, confident, professional and pleasant. The area was cleaned up and the new equipment is sitting nice and pretty. Ontime Piping And Heating has a customer for life. I will most definitely recommend Ontime Plumbing And Heating to anyone and everyone. This day and time finding these types of businesses with some type of integrity is hard to come by. Matty is definitely old school and a businessman of his word. Ontime Piping And Heating deserves a professionalism, Integrity and AWESOME job AWARD! Thank you Angi and thank you Ontime Piping And Heating!"

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.
