Heat Pump Water Heater Installation in Frederick, MD
A homeowner in Frederick, MD was ready to move away from a gas-fired water heater in their basement. The goal was a full conversion — replacing the existing unit, capping the gas and vent lines, and stepping up to a more efficient electric system that would reduce long-term operating costs.
Brian installed an LG 80-gallon heat pump water heater, a square-profile unit with inverter-driven heat pump technology and a UEF of 3.9 — a significant efficiency jump over a standard electric resistance model. The tank features enamel coating and an anode rod to resist corrosion, and it carries a 10-year warranty on both the tank and compressor. The unit connects to LG’s ThinQ Wi-Fi platform, giving the homeowner remote control over operating modes — Auto, Heat Pump, Turbo, Vacation, and Schedule — along with live temperature monitoring from a phone. A required surge protector was installed alongside the unit to protect the system from transient voltage events. Brian also installed a 4.5-gallon expansion tank and a drain pan at the time of the water heater swap, avoiding the need to drain the house for the expansion tank work. The existing gas supply and vent line were capped and decommissioned as part of the same visit. Permits were pulled for the job.
With the conversion complete, the homeowner has a high-capacity electric system that no longer depends on natural gas service. The LG unit’s 10-year tank and compressor warranty provides long-term coverage on the core equipment. The installation is Tax Credit Eligible, and the unit carries an Energy Star rating — both documented at the time of the project.
Heat Pump Water Heater Installation in Frederick, MD
A homeowner in Frederick, MD was ready to move away from a gas-fired water heater and upgrade to a high-efficiency electric system. The switch meant capping the existing gas and vent lines, so the project required a permit — pulled before work began to keep everything above board.
Matt installed a 58-gallon LG heat pump water heater with a UEF of 3.9, a significant efficiency jump over a conventional tank. The unit runs on inverter-driven heat pump technology as its primary heat source, with two backup heating elements for reliability if the heat pump component ever needs attention. A 2.1-gallon expansion tank was added to the cold-water supply line, and a drain pan was set beneath the unit at installation. Because heat pump water heaters pull moisture from the surrounding air as part of their operation, a new condensation pump with vinyl tubing was run to an existing drain location to handle that output. The existing gas supply and vent line were capped as part of the same visit. A surge protector required by LG for the installation was also connected to protect the unit from electrical transients. The LG carries a 10-year warranty covering both the tank and compressor.
With the gas line decommissioned and the new system running, the homeowner has a water heater that costs significantly less to operate than the unit it replaced. The installation is permitted and inspected, the equipment qualifies for a federal tax credit, and the 10-year tank and compressor warranty provides long-term coverage on the investment.
