Large Capacity 75 Gallon Gas Heaters in Hartford, CT
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.
Thermal Expansion Tank Installation in Hartford
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.
Power Vent Gas Water Heater Installation in Hartford, CT
For homes in Hartford, CT 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 experienced 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.

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

Frequently Asked Questions About Gas Water Heater Replacement in Hartford
The cost for gas water heater replacement in Hartford, CT usually ranges from $1,200 to $3,000, including the unit and installation. This can vary based on the model, capacity and any needed changes to gas lines or venting. We provide a detailed, upfront quote after assessing your needs.
Most gas tanks last 8 to 12 years. Sediment from hard water and extreme garage temperatures can shorten that. Annual flushing and anode checks help them last for more years.
Replacing a gas water heater involves working with gas lines, water connections and venting, which can be dangerous if not done correctly. It is highly recommended to hire a licensed professional like GLV Plumbing for safety and code compliance.
Atmospheric vent water heaters use natural convection to vent combustion gases up a chimney or flue. Power vent models use an electric fan to force gases out, allowing for more flexible venting options and often higher efficiency due to more complete combustion.
Water pooling at the base, rusty hot water, rumbling or popping sounds and a tank over 10 years old are typical signs. A leak from the tank itself cannot be repaired.
Absolutely. Modern gas water heaters are significantly more energy-efficient than older models, especially if your current unit is over 10 years old. Upgrading can lead to noticeable savings on your monthly utility bills by reducing gas use.
Most standard gas water heater replacements in Hartford can be completed within 3 to 5 hours. More complex installations, such as converting to a different type of unit or significant plumbing changes, may take longer.
A typical gas water heater has a lifespan of 10 to 12 years with proper maintenance. Factors like water quality in Hartford, such as hard water causing mineral buildup, and usage patterns can influence its longevity.
