These sophisticated systems require expert setup to work at their best, and our team is proficient in all Navien models.
Tank to Tankless Conversions in Trenton
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 often 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 haul away your old tank and patch the old flue penetration.
Electric Tankless Water Heater Installation in Trenton, NJ
Electric tankless water heaters are an excellent option for homes in Trenton 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. GLN Plumbing provides expert 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.

Tankless vs Tank Cost Comparison in Trenton, NJ
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 fits your budget.
