Mike Reynolds
Lead Reviewer · Phoenix, Arizona
Mike Reynolds is the lead reviewer at Tankless Geek. He has spent more than two decades working around residential plumbing, hot-water equipment and home-energy systems.
Mike began his career in Ohio's plumbing and building-supply industry, helping contractors and homeowners select water heaters, components and installation equipment. After relocating to Arizona, he developed a particular interest in tankless technology and the challenges that affect real-world performance: water hardness, flow rates, gas capacity, electrical requirements and household demand.
Over the years he has evaluated gas, propane and electric tankless systems for homes of different sizes and climates. His approach focuses on practical questions: will the unit provide enough hot water, what will installation involve, how much maintenance will it need, and is the higher purchase price justified?
He joined Tankless Geek to make those decisions easier — comparing specifications, installation requirements and long-term ownership costs in plain language instead of repeating manufacturer claims.
