Water Heater Services

Water Heater Repair

Not every water heater problem requires replacement. Our plumbers inspect the system to identify the cause of the issue and determine whether a repair is the most practical option. We service common water heater problems including inconsistent water temperatures, lack of hot water, leaking connections, faulty thermostats and heating components, pilot and burner issues, pressure relief valve problems, and sediment buildup.

Water Heater Replacement & Installation

When a water heater is aging, leaking, inefficient, or no longer worth repairing, Legacy Plumbing can help you select and install a replacement that meets your household's hot water needs. We install traditional tank-style and tankless water heaters and can help determine the appropriate system and capacity based on your home, family size, available fuel source, and hot water usage.

Every installation is completed with attention to proper connections, venting, safety, and reliable long-term operation. We also remove and dispose of your old water heater as part of the replacement process.

Tankless Water Heater Upgrades

Thinking about switching to tankless? We can evaluate your home and determine what modifications may be necessary for a tankless water heater installation. Tankless systems heat water on demand and can be an excellent option for homeowners looking for a compact, efficient hot water solution.

Types of Water Heaters

Choosing the right water heater depends on your home, available utilities, hot water demand, available space, and budget. Legacy Plumbing installs and services gas tank, electric tank, tankless, and high-efficiency water heater systems throughout South Jersey. Whether you're replacing an existing unit or considering an upgrade, we can help you understand your options and select a system that fits your household's needs.

Gas Tank Water Heaters

Gas tank water heaters are one of the most common choices for residential hot water. These systems store heated water in an insulated tank and use natural gas or propane to maintain the desired temperature.

Gas water heaters typically offer strong recovery rates, making them a practical choice for households that use larger amounts of hot water throughout the day. They are available in several tank sizes to accommodate different household needs.

Electric Tank Water Heaters

Electric tank water heaters operate similarly to traditional gas models but use electric heating elements instead of a gas burner. They can be a practical option for homes without natural gas or where installing a gas-fired water heater isn't desirable.

Electric models generally have straightforward installation requirements and do not require conventional combustion venting. The best choice depends on your home's electrical capacity, hot water demand, and local energy costs.

Tankless Water Heaters

Tankless water heaters heat water as it is needed rather than continuously storing hot water in a tank. When a hot water fixture is opened, the system activates and heats the water as it passes through the unit.

A properly sized tankless water heater can provide continuous hot water while taking up significantly less space than a traditional tank. Tankless systems can also offer improved energy efficiency because they reduce the standby heat loss associated with storing hot water.

Tankless installations may require upgrades to gas piping, venting, electrical service, or other components depending on the home and equipment selected. Legacy Plumbing can evaluate your existing system and determine what is required for a proper installation.

High-Efficiency & Condensing Water Heaters (Power Vents)

High-efficiency water heaters are designed to capture and use more of the energy produced during operation. Condensing gas water heaters, for example, recover additional heat from combustion gases that would otherwise be exhausted.

These systems can reduce energy consumption compared with conventional models, although installation requirements and upfront costs may be higher. They're worth considering when replacing an older system or when energy efficiency is a priority.

Which Water Heater Is Right for Your Home?

There isn't one type of water heater that's right for every home. Household size, hot water usage, existing gas or electrical service, available space, efficiency goals, installation costs, and long-term operating expenses should all be considered. Legacy Plumbing can evaluate your home's existing system and help you compare traditional tank, tankless, and high-efficiency water heater options. We'll explain the differences and help you choose a system that provides the hot water your household needs without unnecessarily oversizing the equipment.
