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.
Why Medford Homeowners Are Switching to Tankless
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:
- An uninterrupted hot water supply for larger households
- Reduced monthly utility bills
- A space-saving, wall-mounted footprint
- A longer service life than tank models
- Better overall energy efficiency
- Less standby heat loss
- Steady water temperature throughout the home
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.
The Right System Starts With the Right Sizing
Picking a tankless water heater isn’t just about brand — sizing it correctly matters more.
We evaluate:
- Household size
- Number of bathrooms and fixtures
- Peak simultaneous hot water use
- Current plumbing layout
- Available gas supply
- Venting needs
- Where the unit will be installed
- Plans for future additions to the home
Matching the unit to your home’s real-world demand is what keeps performance and efficiency high for years.
Local Water Conditions Matter
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:
- Hardness
- Iron content
- Sediment
- Low pH
- Mineral scale
- Existing softener performance
- Filtration needs
Catching these issues up front helps prevent scale buildup inside the unit, keeps efficiency high, and extends the life of your investment.
Signs Your Water Heater Needs Replacing
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:
- Leaking around the tank or fittings
- Rust-tinted hot water
- Temperature swings
- Not enough hot water to go around
- Climbing energy bills
- Repeat repair calls
- Banging or rumbling noises
- A unit older than ten years
We’ll assess your current system honestly and tell you whether repair or replacement makes more financial sense long term.
Rebates That Lower Your Cost
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.
Financing Built Around Your Budget

- 0% promotional financing
- PSE&G financing
- South Jersey Gas financing
- Enhancify home improvement loans
We’ll walk through the options and help you find a plan that fits.
