Expert Tankless Water Heater Installation in Norwich, CT
GLV Plumbing knows that hard water is the biggest threat to tankless units, since scale builds up inside the heat exchanger. Public water in most of Connecticut runs soft to moderately hard, and soft water can be mildly corrosive to older copper plumbing. We install service valves for easy flushing and recommend a scale inhibitor or softener to protect your warranty. You get efficient, endless hot water that keeps performing.
Our expertise includes:
- Accurate sizing and model selection for your home.
- Clean integration with existing plumbing systems.
- Careful sizing and venting for optimal performance.

Tankless vs Tank Cost Comparison in Norwich, CT
Tankless installation costs more upfront than a standard tank because of the unit price, gas line upgrades and venting changes. Over time, lower standby energy losses and a longer expected lifespan offset part of that cost. Tankless units often last 15 to 20 years with proper descaling, compared with about 8 to 12 years for many tanks in hard water areas. We give you a side-by-side quote so you can decide what suits your budget.

Upgrading from Tank to Tankless in Norwich, CT
Making the switch from a traditional tank water heater to a tankless system involves more than simply swapping units. It often requires changes to gas lines, electrical wiring and venting. GLV Plumbing manages all aspects of this conversion, making sure all upgrades meet current codes and your new tankless unit performs at its best, giving you a modern hot water solution in Norwich, CT.
Gas Tankless Water Heater Installation in Norwich
For many homes in Norwich, gas tankless water heaters are a common choice due to their powerful heating and lower operating costs compared to electric models. Our licensed technicians handle all aspects of gas line connections, venting and combustion air requirements, so your system operates safely and efficiently. We work with leading brands like Rinnai and Noritz to provide high-performance, on-demand hot water.
Electric Tankless Water Heater Installation in Norwich, CT
Electric tankless water heaters are an excellent option for homes in Norwich where natural gas is not available or preferred. These units are often smaller, simpler to vent and can be installed closer to the point of use. GLV Plumbing provides professional electrical sizing to make sure your home's panel can safely support a new electric tankless unit, offering consistent hot water without the need for a gas line.
Rinnai, Navien and Noritz Installation in Norwich, CT
We install leading tankless brands including Rinnai, Navien, Noritz and Rheem.

Commercial Tankless Water Heater Installation in Norwich
Businesses often have higher and more consistent hot water demands than homes.

We understand the value of minimal disruption to your operations during installation, providing a quick and professional setup in Norwich.
Tank to Tankless Conversions in Norwich
Converting from a tank requires more than swapping units. A 40 gallon tank heater uses roughly 40,000 BTU, while a whole-home tankless unit may need up to 199,000 BTU, so the gas line usually needs to be upsized. Venting changes from a metal flue to PVC or stainless, and the unit moves to a wall location. We remove and dispose of your old tank and patch the old flue penetration.

Navien is a leading brand known for its advanced condensing technology and strong energy efficiency.
