What the Pros Say
"For 9 out of 10 service calls, a standard tank heater is a straightforward replacement. We can have a family's hot water back on in a few hours with minimal surprises. Tankless units often require significant plumbing, gas line, and venting upgrades, which adds time and cost."

Mike Johnson
Plumbing Technician, 15 years"When a customer calls with a leaking heater, they usually need a fast, affordable solution. A conventional tank heater meets that need perfectly. We present tankless as a long-term investment option, but the upfront cost is a major hurdle for many families."

Sarah Chen
Service Manager, Apex Plumbing"A tankless system is fantastic for large families or homes with high-demand fixtures like a jacuzzi tub. You get endless hot water and save on energy bills. However, you must factor in the cost of a potential gas line upgrade and annual descaling maintenance, especially in areas with hard water."

Carlos Rodriguez
Master Plumber"We recommend what's right for the customer's situation and budget. For a family planning to stay in their home for 15+ years, the math on a tankless might work out. For most people, the reliability and low initial cost of a traditional tank is the smarter financial decision."
