Tankless Water Heater Installation for Buffalo Grove homes
The details that matter with tankless are the gas supply and venting, since an on-demand unit fires at a higher rate than a standing tank and vents differently. We size the unit to your household's real hot-water demand, confirm the gas line and venting can support it, and handle the water connections so the install is clean and to code.
Licensed, insured installers mount the unit, run the gas, venting, and water connections, and test it before leaving. The old tank is removed and hauled away, and the warranty is registered. Where a qualifying high-efficiency unit earns a Nicor rebate, we hand off the paperwork and confirm the current program in your estimate.
