More Hot Water With Less Wasted Energy

Tankless systems are known for providing a continuous supply of hot water when properly sized. That can be helpful for busy households where showers, laundry, and dishwashing often happen close together.

Because the system does not keep dozens of gallons hot throughout the day, it may use less energy than an older storage-tank model. Tankless equipment also takes up less space, reduces the risk of a large tank rupture, and can last longer than many conventional water heaters when maintained properly.

Planning a Successful Tankless Upgrade

Switching to tankless involves more than removing the old tank and connecting a new unit. The home must have adequate gas flow or electrical capacity, proper venting, sufficient water pressure, and plumbing that supports the required flow rate.

Household demand matters as well. A unit that is too small may struggle when several fixtures require hot water at once. We evaluate the number of bathrooms, appliances, peak usage, fuel source, and existing connections before recommending equipment.

Installation costs may be higher when gas lines, wiring, vents, or plumbing need upgrades. We explain those requirements clearly so homeowners understand the full scope of the project before work begins.

Common Tankless Water Heater Repairs

Mineral scale is one of the most common causes of tankless water heater trouble. Buildup inside the heat exchanger can restrict flow, reduce efficiency, and cause the system to shut down. Routine flushing is especially important in homes with hard water.

Other repairs may involve clogged inlet filters, failed ignition components, flame sensors, heating elements, flow sensors, control boards, or venting problems. Error codes, changing water temperatures, reduced flow, unusual noises, and repeated shutdowns are all signs that the unit needs attention.

Pro Flo plumbing fixed two issues in our home that we had been putting off. The price was fair, our plumbers were outstanding and both jobs were done right.
Pro Flo also has now helped the nonprofit animal shelter my wife and I work with (APS Caswell) twice and did a great job for the shelter as well. When you go with Pro Flow, you can count on knowledgeable professionals explaining everything thoroughly, and getting the job done right for a reasonable price. I know my family are Pro Flo customers for life.

Paid this company for nothing! Told them the issue (disconnected pipe and clogged) the man claimed he climbed under the house and seen no issue then charged me a service fee but he didn’t do anything and I had to call another company out and they had the problem fixed within an hour and a new pipe connected.
