We’ll Find the Right Water Heater Service

A water heater that runs poorly or stops working affects everything from morning showers to dishwashing. The right fix depends on what the unit actually needs, and that starts with a proper diagnosis.

Our water heater services include:

Water Heater Repair: We diagnose and repair heating elements, thermostats, pressure relief valves, and other components in tank and tankless water heaters.
Water Heater Replacement: We remove the existing unit and install a replacement matched to the household's hot water demand and available space.
Water Heater Installation: We install new tank and tankless water heaters, handling connections for gas, electric, and combination systems.
Tankless Water Heater Service: We repair and install on-demand water heaters, heating water as the flow passes through the unit and eliminating the standby cycle tank systems require.
Flushing and Maintenance: We flush sediment from tank water heaters to restore efficiency and extend the service life of the unit.

Choosing between repair and replacement depends on the unit's age, the cost of the repair, and the efficiency gains a newer system provides. We walk through the options before any work starts.

Tank vs. Tankless Water Heaters

Traditional tank water heaters store a set volume of water and heat the stored supply continuously to maintain temperature. Tankless water heaters skip the storage tank, heating water on demand as the flow passes through a coil when the unit activates. Because tankless units only heat water when it is needed, they avoid the ongoing energy use of maintaining a standing temperature.

Tank systems suit households with consistent hot water schedules and lower upfront installation costs. Tankless units use less energy over time and work well where demand is spread throughout the day. RooterMan of Exeter, NH can assess your household's demand and available space and help you determine which system fits.

Common Signs Your Water Heater Needs Service

Water heaters give off warning signs before failing completely. These are the most common indicators service is needed:

Inconsistent Water Temperature: Water going from hot to cold mid-use, or taking longer than usual to reach temperature, often points to a failing heating element or thermostat.
Discolored or Rusty Water: Rust-colored water from hot taps indicates corrosion inside the tank, which typically signals the unit is nearing the end of its service life.
Unusual Sounds from the Tank: Popping or rumbling during heating cycles often comes from sediment accumulating on the heating element inside the tank.
Water Around the Base of the Unit: Pooling near the water heater signals a leak from the tank, fittings, or pressure relief valve and requires prompt inspection.

Most tank water heaters have a service life of 8 to 12 years. If yours is reaching the end of its range and showing any of these signs, repeated repairs often cost nearly as much as replacement.
