40 and 50 Gallon Tank Replacement in Claymont
The 40 and 50 gallon gas tank is the workhorse of most Delaware homes. When yours starts leaking from the bottom seam or produces rusty water, replacement is the only real fix. We match the new tank's height and diameter to your space and reuse the venting when it is in good shape. Newer tanks are sometimes taller due to efficiency standards, so we check clearance before ordering. Most of these jobs take about two to three hours.
Large Capacity 75 Gallon Gas Heaters in Claymont, DE
Big families, soaking tubs and multiple showers running at once often need a 75 gallon tank or a high-recovery 50 gallon model. These heaters use larger burners, sometimes 75,000 BTU, and may need a bigger gas line and flue. We check your meter and pipe size to make sure the larger tank gets the gas it needs. A high-recovery unit can be a good middle ground when space is limited. We walk you through recovery rates so you pick the right fit.
Power Vent Water Heater Replacement in Claymont
Power vent gas water heaters use an electric blower to push exhaust through PVC pipe, which lets them sit far from a chimney or roof flue. When the blower motor or pressure switch fails again and again, replacing the whole unit can be the better choice. We install new power vent models and confirm a dedicated outlet is available. Venting length and number of elbows must stay within the manufacturer's limits. Power vent tanks cost more but solve tricky placement problems.
Thermal Expansion Tank Installation in Claymont
Many water utilities install pressure regulators or backflow devices that create a closed system. When water heats and expands, pressure spikes can strain your tank and fixtures. Code commonly requires a thermal expansion tank on these systems. We install a properly sized expansion tank and pre-charge it to match your water pressure. This simple add-on can help your new heater last longer.
Standard Vent Gas Water Heater Replacement in Claymont
Many homes in Claymont rely on standard atmospheric vent gas water heaters. When these units reach the end of their lifespan, typically 10 to 12 years, we provide expert replacement. Our service includes safely disconnecting the old unit, installing a new, energy-efficient model, and connecting it properly to your existing natural gas line and flue venting system. We also check for enough combustion air and perform a thorough leak test for safety and efficiency.

Tankless Gas Water Heater Conversion in Claymont
If you are looking to switch from a traditional tank to a tankless gas water heater, GNV Plumbing can handle the entire conversion in Claymont.
