Tank-to-Tankless Conversion in Old Lyme: what is different here

Many Old Lyme conversions involve propane, since natural gas is limited across much of town. We size the propane line for the tankless unit's higher demand and plan the new vent. In Lyme Street's historic homes, vent placement is planned to stay out of sight.

How the job runs

  1. Site check

    We measure your gas meter and lines, find a venting route to an outside wall and check where the unit will hang.
  2. Plan the switch

    We explain the gas line, venting and drain work, and size the unit for winter groundwater.
  3. Remove the tank

    We drain and disconnect your old tank, carry it out, and cap the old vent if it is no longer used.
  4. Upgrade gas and venting

    We run the larger gas line, install new venting and add a condensate drain if the unit needs one.
  5. Mount, connect and test

    The unit goes on the wall with service valves, then we test flow at several taps and walk you through it.

Old Lyme questions

Yes, propane tankless units are common in Old Lyme. The fuel line and regulator need to deliver more fuel at once than a tank uses, so we check sizing. Your propane supplier may need to confirm tank and regulator capacity. We include any line upgrades in the quote.
