Whether your family is upgrading from an aging tank-style unit or building efficiency into a larger home renovation, Harriett’s Plumbing & Water Treatment installs, replaces, repairs, and services high-efficiency tankless water heaters across Medford, Medford Lakes, Tabernacle, and the surrounding Burlington County area.
Our licensed technicians specialize in gas tankless systems built to deliver dependable hot water, reduce energy costs, and hold up over years of daily use. Each installation is planned around your
household’s specific plumbing setup and hot water demand.
Conventional tank water heaters keep a large reservoir of water hot around the clock, whether anyone’s using it or not. Tankless units instead heat water on demand, the moment a faucet or appliance calls for it — which means less wasted energy and hot water that doesn’t run out.
Homeowners across Medford and Medford Lakes are choosing tankless systems for:
From back-to-back showers before school to running the dishwasher and washing machine at once, a correctly sized tankless system keeps up with a busy family’s routine.
Picking a tankless water heater isn’t just about brand — sizing it correctly matters more.
We evaluate:
Matching the unit to your home’s real-world demand is what keeps performance and efficiency high for years.
Many homes throughout Medford and neighboring Tabernacle deal with water quality issues that can shorten the life of plumbing equipment. Because Harriett’s also handles residential water treatment, we check water quality as part of every tankless installation.
That review can include testing for:
Catching these issues up front helps prevent scale buildup inside the unit, keeps efficiency high, and extends the life of your investment.
Most homeowners wait until their water heater fails outright — but replacing it proactively often avoids emergency repairs and water damage to your home.
Consider replacement if you’re noticing:
We’ll assess your current system honestly and tell you whether repair or replacement makes more financial sense long term.
A qualifying high-efficiency tankless installation can open the door to manufacturer and utility rebates — currently up to $850 depending on the equipment and programs available at the time of installation.
We check every rebate option before your installation so nothing gets left on the table.
