Water heater installation involves more than swapping out an old tank — correct sizing, venting, and code compliance determine whether a new unit runs efficiently for the next 8–12 years or fails early. Long's Plumbing has installed gas, electric, and tankless systems throughout Cornish, NH since 2016, and every install includes a load calculation based on household size and fixture count rather than a one-size-fits-all swap.\n\nOwner Brock Long brings hands-on plumbing experience to every job, and the company is BBB accredited with an A+ rating. Homeowners in Cornish, NH can expect a straightforward walkthrough of tank versus tankless options, upfront pricing before work begins, and a finished install that meets code — not just a unit bolted into the same spot the old one occupied.
