Tankless Water Heater Installation in Norfolk & Virginia Beach | Anchor Plumbing & Gas
Endless Hot Water. No Tank. No Standby Waste.
A tankless water heater does something a traditional tank unit fundamentally cannot — it heats water on demand, only when you need it, in the exact quantity you need it. No tank of water sitting there losing heat around the clock. No running out of hot water mid-shower when someone starts the dishwasher. Just hot water, whenever you turn on the tap, for as long as you need it.
At Anchor Plumbing & Gas we install Rinnai and Navien tankless water heaters throughout Hampton Roads — two of the most respected names in the tankless industry. We size every system correctly for your home's demand, handle every aspect of the installation, and stand behind our work.
How Tankless Water Heaters Work
A tankless unit — also called an on-demand or instantaneous water heater — uses a high-powered burner or heating element to heat water directly as it flows through the unit. When you open a hot water tap, cold water enters the unit, passes over the heat exchanger, and exits at your set temperature within seconds. When you close the tap, the unit shuts off completely.
There is no storage tank. There is no standby heat loss. There is no finite supply of hot water to exhaust.
The Real Benefits of Going Tankless
Endless Hot Water The most immediate benefit for most Hampton Roads homeowners. A properly sized tankless unit delivers continuous hot water regardless of how many people are in the home or how many fixtures are running simultaneously — as long as the unit is sized correctly for the demand.
Energy Efficiency A traditional tank water heater runs its heating element or burner periodically all day and night to maintain stored water temperature — even when no one is home and no hot water is being used. A tankless unit uses energy only when hot water is actively flowing. For most households that translates to meaningful energy savings over time.
Space Savings A tankless unit mounts on a wall and takes up a fraction of the space a tank unit requires. For Hampton Roads homes with limited utility space — particularly older Norfolk and Portsmouth homes where mechanical space is tight — this is a real practical advantage.
Longer Lifespan A properly maintained tankless water heater typically lasts 20 years or more — roughly twice the lifespan of a traditional tank unit. The long-term cost of ownership is often lower even accounting for the higher upfront investment.
No Risk of Tank Failure Tank water heaters fail by corroding from the inside and eventually leaking — sometimes significantly. There is no tank to corrode with a tankless unit.
The Honest Tradeoffs
We believe in giving you the full picture. Tankless isn't the right answer for every situation and we'll tell you that honestly.
Higher Upfront Cost Tankless units and their installation cost more than a standard tank replacement. The long-term economics typically favor tankless but the upfront investment is real.
Gas Line Requirements Most tankless gas units require a larger gas line than a traditional tank water heater. If your existing gas line is undersized we'll need to upsize it as part of the installation — which adds to the cost. We assess this before giving you a price so there are no surprises.
Venting Requirements Tankless units require proper venting to the exterior. In some Hampton Roads homes — particularly older construction — the venting configuration needs to be evaluated as part of the installation scope.
Cold Water Sandwich In some situations with tankless units, a brief burst of cold water can occur between hot water draws. This is a known characteristic of tankless systems, not a defect, and can be addressed with a recirculation system in homes where it's a concern.
We'll assess your home before recommending tankless and tell you honestly whether it's the right fit — including what the full installation scope and cost will be.
The Brands We Install
Rinnai Rinnai is one of the most recognized names in tankless water heating and has been manufacturing tankless units longer than almost anyone in the industry. Their residential and commercial units are known for reliability, efficiency, and strong warranty support. We recommend Rinnai for homeowners who want a proven, widely supported system.
Navien Navien is one of the fastest-growing tankless brands in North America and consistently earns top marks for efficiency and technology. Their NPE series condensing tankless units are among the most energy-efficient residential water heaters available. We recommend Navien for homeowners who prioritize maximum efficiency and are interested in the latest in tankless technology.
We'll help you choose between the two based on your home's specific needs, your hot water demand, and your priorities — with honest information about the differences.
Sizing Matters — A Lot
The most common tankless installation mistake is undersizing. A tankless unit that can't keep up with your home's simultaneous hot water demand will leave you with lukewarm water when multiple fixtures run at the same time — and that's a failure of the installation, not the technology.
We size every tankless installation based on your home's actual peak demand — number of bathrooms, appliances, household size, and groundwater temperature — before recommending a unit. A correctly sized system delivers on the promise of endless hot water. An undersized one doesn't.
Tankless Installation in Hampton Roads Homes
Older Norfolk & Portsmouth Homes Historic homes in Ghent, Larchmont, Freemason District, and Old Towne Portsmouth often have original gas lines and limited mechanical space that need to be evaluated before a tankless installation. We assess everything upfront so you know exactly what the full scope and cost involves.
New Construction in Chesapeake & Virginia Beach New construction is increasingly being built with tankless water heaters as the standard. If you're building or have recently moved into a new Chesapeake or Virginia Beach home and want to upgrade to tankless, we size and install the right system for your household.
Mid-Century Homes Throughout Hampton Roads Homes built in the 1950s through 1980s often need gas line evaluation and venting assessment before tankless installation. We handle both as part of the installation process.
