Why Choose GLV Plumbing for Tankless Water Heater Replacement in New Haven, CT?
A tankless heater is only as good as its gas supply and venting. We measure both before we quote, so your new unit fires at full output instead of shutting down on high demand.
- Clean Venting, We route venting to meet manufacturer clearances from windows, doors and roof edges.
- Longer Lifespan, Tankless water heaters typically last longer than conventional tank units, often up to 20 years with proper maintenance, giving you better long-term value.
- Energy Savings, Tankless water heaters only heat water when you need it, which can significantly reduce energy use compared to traditional tank models, a big plus for Connecticut utility bills.

Tank to Tankless Conversions in New Haven, CT
Converting from a 40 or 50 gallon tank to tankless frees up floor space and ends standby heat loss in a garage or closet. The catch is that tankless units usually need a larger gas line, often three quarter inch or bigger, plus new venting. We check your meter size and pipe run before quoting so there are no surprises mid-job. We also cap or reroute the old flue and seal the roof penetration if it is no longer used. Plan for a conversion to take a full day.
Like-for-Like Tankless Swaps in New Haven
When your existing tankless has a cracked heat exchanger or a failed control board that is not worth repairing, a direct replacement is often the fastest fix. We match the new unit to your current gas line, venting type and mounting location whenever possible. Many Rinnai and Navien models share similar footprints, which keeps wall patching to a minimum. We also replace the old service valves if they are corroded or seized. Most like-for-like swaps are finished in four to six hours.
