Standard Vent Gas Water Heater Replacement in Wilmington
Many homes in Wilmington 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 adequate combustion air and perform a thorough leak test for safety and efficiency.
Power Vent Gas Water Heater Installation in Wilmington, DE
For homes in Wilmington, DE where traditional venting is not possible, or for those wanting higher efficiency, power vent gas water heaters are an excellent choice. These units use a powered fan to exhaust combustion gases, offering more flexibility in installation location. Our technicians are skilled in installing these more complex systems. That includes running new PVC vent piping and making proper electrical connections for the blower motor, all while following local codes.
Propane Gas Water Heater Replacement in Wilmington, DE
For homes outside the natural gas grid in Wilmington, DE, or those that rely on propane, we offer dedicated propane gas water heater replacement services. Our team is experienced with propane systems, ensuring correct gas line sizing, proper combustion and safe venting. We will replace your old propane unit with a new, dependable model. All connections are secure and up to code for propane gas appliances.
Thermal Expansion Tank Installation in Wilmington
Many water utilities install pressure regulators or backflow devices that create a closed system. When water heats and expands, pressure spikes can stress your tank and fixtures.

This simple add-on can help your new heater last longer.

Atmospheric Vent Tank Upgrades in Wilmington, DE
Most older homes have atmospheric vent water heaters that rely on natural draft up a metal flue. We inspect the flue pipe for rust, proper slope and correct connector size during replacement.
