"I bought a water heater. They first connected me with a plumbing company that tried to add on $270 for additional materials and labor costs that they could not justify. I returned the water heater, and they again connected me to Holthaus. Holthaus called later that same afternoon and scheduled for the next morning. Dan came out and installed the water heater and new stand in just an hour. He only charged $30 for additional materials related to new gas fittings. He was very polite, transparent, and thorough. I would highly recommend them."

Service Plus Heating, Cooling & Plumbing, is the premier Plumbing provider in Central Indiana. We look forward to serving all of your Plumbing needs. We proudly serve the Indianapolis metro area and look forward to earning your business.

"Company uses its cheap maintenance program (Service Plus Club) to push unnecessary repairs/upgrades, and high-pressure tactics to get you to commit before having a chance to research your true needs or competitive prices. Had an inspection today. Recommended two unnecessary things, including replacing my old, but perfectly working garbage disposal. Who proactively upgrades a working garbage disposal?? I definitely needed a water heater. I consider tankless + a water softener, but their quote was 68% higher than a bid I later got (from a highly recommended small, local business). But, I could save $3k if I agreed to the service that day...which was still 23% higher. When I got the later bid, I told them that I was going with the other company. They offered to match the bid. Really??!! If you can do it for that much, why did you give me an inflated bid to begin with? Nope. Trust broken. Club membership canceled. Never going back. Stay away from this predatory company!"

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.
