Tankless Water Heater Installation in Orlando

Serving Orlando Since 1997, Led by a Licensed Master Plumber

Mercury Plumbing has been handling plumbing projects across the greater Orlando area since 1997, when founder Tom Murphy opened the business after working his way up from apprentice to licensed master plumber. That hands-on experience guides every installation we take on today. We’re fully licensed, insured, and bonded, and we hold an A+ rating with the Better Business Bureau.

We install tankless water heaters for homeowners, custom homes, remodeling projects, multi-family properties, apartment complexes, and commercial buildings. Whatever the property type, we bring the same level of care to the job.

Installation Experience That Handles the Hard Cases

Tankless installation isn’t always a straight swap. In homes without an existing gas line, or where the electrical panel doesn’t have the capacity to support a new electric unit, the project requires additional retrofit work before the heater goes in. These are the jobs where our background sets us apart.

Our team is guided by a master plumber who has spent decades in the trade, and we’ve built a reputation for taking on difficult problems and completing jobs where other plumbers have already tried and failed. Tight installation spaces, gas line retrofits, panel capacity questions: we’ve worked through all of it. We run five stocked, radio-dispatched service vans around the clock, so we’re available when your project needs to move.

Get a Quote with No Upfront Cost

We offer over-the-phone estimates for many jobs and no-charge on-site estimates for larger projects. If you’re weighing the cost of a tankless installation, we can give you a clear picture before any work begins. Flexible financing is also available for bigger projects, so upfront cost doesn’t have to be the reason you hold off.

We’re available 24 hours a day, seven days a week, including same-day appointments. Call (407) 315-1187 to talk through your project with Mercury Plumbing.
