Signs a tankless unit makes sense for your house
Most homeowners call about tankless water heater installation for one of three reasons. The old tank is at the end of its life. The family has outgrown it and the last shower of the morning runs cold. Or the heater closet is needed for storage and a wall-mounted unit frees the floor. If any of those sound familiar, a tankless water heater Columbia SC quote is worth a call. Still weighing tank against tankless? Our guide to the five types of water heaters covers that decision.
An outdoor gas tankless unit. Outdoor models vent through the slot on the face, so no vent pipe runs through the house.
What we do on a tankless water heater installation
Every tankless water heater installation starts with a sizing visit. Manny counts fixtures, checks incoming water temperature, and confirms the gas line can feed the new unit. From that visit you get a written price covering the unit, the install, and any gas or vent work the house needs.
On install day we drain and remove the old tank and mount the new unit. We run the gas connection, set the venting, add the isolation valves that make future service a ten-minute job, and connect the water lines. Then we fire it, set the temperature, and check every joint. We pull the permit and schedule the inspection.
Gas line, venting, and permit: the three things that change
A standard gas tank heater draws roughly 40,000 BTU per hour. A whole-house tankless unit like Rinnai’s outdoor RE199eN draws up to 199,000 BTU per hour. That jump is why many Columbia homes need the gas line upsized before a tankless water heater installation will pass inspection. Venting changes too. Most new units vent in sealed PVC through a side wall instead of the old metal flue. Columbia and Lexington County both require a permit for a water heater swap; our permit guide explains what the inspector looks for.
Before you call
Have three things ready and the quote goes faster. Know whether the current heater is gas or electric, since an electric-to-gas switch means running a new gas line. Count the bathrooms and note whether two showers often run at once. Send a photo of the model label on the old tank. With that, Tanya can book the sizing visit the same week.
Tankless water heater installation is not right for every house, and we will tell you when a conventional tank is the better buy. When it is the right answer, you get a unit sized for your family, installed by a licensed SC Master Plumber, with the price agreed before we start.
