Water Heater Installation Near Downtown Rowlett Station

The station at 5000 Martin Drive began as a bus facility, the Rowlett Park and Ride, which opened on May 22, 2000, on a former Missouri-Kansas-Texas rail corridor DART had bought for future light rail. Before it, commuters parked at Christian City Church about 3.5 miles east at Lakeview Parkway and Dalrock Road, and DART paid the church $10,000 a year. Groundbreaking for the rail extension was on March 25, 2011, testing began in April 2012, and rail service opened on December 3, 2012, when the facility took the name Downtown Rowlett station.

Since then it has had a few changes. A shuttle linking the station to Greenville began in September 2016, and DART introduced a parking permit system on May 7, 2018, with some lot segments reserved on weekdays for drivers with a free permit available to residents of DART's 14 member cities. Fiscal year 2025 saw 1,106 average weekday riders, up 5%.

A household that catches a train leaves at about the same time, so its showers cluster. That is the peak a heater is sized for, and the number to look at is the first hour rating on the energy label, the hot water a tank delivers in an hour of heavy use. For a tankless unit the sum is flow: two showers at the U.S. EPA WaterSense cap of 2.0 gallons a minute plus a bathroom tap at 1.5 gives 5.5 gallons a minute, and 5.5 x 500 x 65 degrees of rise is 178,750 BTU an hour of output.

A tank that recovers in an hour suits a household that showers in sequence. One whose members all shower in the same fifteen minutes may want a bigger tank or a tankless unit. The sizing guide shows how to count.

Older houses add their own sediment to the hardness NTMWD describes, so a tank that has never been flushed deserves a gentle first flush, a few gallons at a time. The district's January 2015 figure of 183 mg/L, or 10.7 grains per gallon, is the high mark in the tables we found. The flushing guide has the steps.
