Water Heater Installation in Lake Shore Village

Lake Shore Village is a Windsor Homes community in Rowlett, with a sales address at 8522 Watersway Drive and homes on Watersway Drive and Windmere Drive. Windsor's ready-to-build plans there are named Rockport, Laredo, Victoria, Kerrville, Sherman, Lufkin and Crockett, with base prices from about $409,990 to $494,990. The community's overall listing range runs from $419,990 to $599,000, and the school district is Garland ISD. A home on Watersway Drive is listed as built in 2026 at 2,374 square feet, and one on Windmere Drive was under construction in July 2026 at 3,376 square feet with four bedrooms and four baths.

Prices and availability change by the week and we quote none of them. We also found data only for these new builds. If your house is one of the older ones around the community, its age isn't something we could verify, so we look at the label and the connections house by house.

The two homes we found are different sizes of problem. A 2,374 square foot house is typically a three- or four-bedroom plan, and a 50-gallon tank usually serves a household of three or four. The 3,376 square foot house has four bedrooms and four baths, and that is where one tank starts to run out. Our guidance for a four-bath house is a 65 to 80 gallon tank, or a tankless unit sized for the busiest morning, and the arithmetic is on the tankless page.

The figure that counts is the first hour rating on the energy label, which is how much hot water a tank delivers in an hour of heavy use. The sizing guide shows how to read it.

Rowlett's water comes from the North Texas Municipal Water District, which calls it moderately hard because of minerals in Lavon Lake. Its tables show 183 mg/L total hardness in January 2015 and 122 to 160 mg/L in sampled months of 2022 and 2023, which is 7.1 to 9.3 grains per gallon by the district's divide-by-17.12 rule. New plumbing doesn't change that. A lake-side address doesn't either: Lake Ray Hubbard is owned by the City of Dallas, and Rowlett's tap water comes from NTMWD.

In Rowlett, gas is delivered by Atmos Energy and electricity by Oncor, and the EIA's 2020 survey puts gas at about 48% of U.S. homes' main water heating fuel and electricity at about 46%. A hybrid is estimated at $3,000 to $5,500 and a tankless conversion at $3,800 to $7,500. The DOE puts a tankless unit's efficiency gain at 24% to 34% for homes using 41 gallons a day or less, and ENERGY STAR shows $550 a year saved by a heat pump heater for four people against a standard electric tank. Each needs a plan for the gas line, the vent or the drain, and it is cheapest to settle in a house this new.

Our shop is 3.4 miles from Lake Shore Village in a straight line. A like-for-like swap takes 3 to 5 hours, and the written quote comes before the old heater is touched. Texas requires work for customers to be by a plumber licensed through the State Board of Plumbing Examiners, and Texas cities set their own permit rules, so we confirm what Rowlett requires and show any permit as its own line.
