Extending the pool season with a gas pool heater means dedicating a substantial gas line from your service to the pool equipment pad. Gas pool heaters are high-BTU devices (typically 250,000 to 400,000 BTU) that often require gas service upsizing in addition to the new line install. Tim Whistler Plumbing handles the full installation across the DMV with appropriate permits and inspections.
Three components: (1) gas service evaluation to confirm capacity (many existing residential services need upsizing to handle a 300,000 plus BTU pool heater on top of indoor appliances); (2) a dedicated gas line from the meter or sub-distribution panel to the pool equipment pad, typically buried per code with appropriate sleeve protection; (3) electrical service for the heater's controls and ignition. Our team is licensed across plumbing, gas, and electrical to handle all three.
We assess your existing gas service, do a load calculation that accounts for the pool heater plus existing appliances, plan the line routing and any service upsizing required, pull the appropriate permits, install the line and electrical service, pressure test, coordinate the inspection, and verify operation before we leave.
Standard pool heater gas line installations in the DMV typically run $2,500 to $6,500 installed, depending on the distance from the gas meter to the pool equipment pad, whether the gas service requires upsizing, and any electrical work needed for the heater controls. We provide written, itemized quotes.
Often no without upsizing, especially for higher-BTU pool heaters. A typical 250,000 BTU pool heater nearly doubles the gas demand of a typical residential service. We do a load calculation as part of the assessment to confirm whether upsizing is required.
With appropriate sizing and sub-distribution, yes. Many of our McLean and Bethesda installations include both. We design the gas distribution to handle all the outdoor appliances under one engineered system.
