Right sizing, code-compliant venting, isolation valves installed by default. Done once. Done right.
Tankless water heaters are capable of 20-plus year service lives. Most don't get there.
The reason isn't the equipment. It's the install.
A tankless heater installed with the wrong gas line capacity, the wrong vent configuration, no isolation valves, or sizing that doesn't match the household's actual hot water demand will underperform from day one and fail prematurely. The unit isn't broken. The install was.
We do tankless installs that match what these units are actually capable of.
The full menu. Each item done to a standard that lasts.
Sized by actual hot water demand. Gas line capacity, venting, electrical, and recirculation needs all addressed during the install.
Higher flow rates and lower operating costs. Proper gas line sizing, manufacturer-specified venting, and condensate management completed correctly.
Ideal for homes without gas or point-of-use needs. Full electrical capacity assessment before recommendation.
We install all major brands and match the right unit and features to your actual usage patterns.
Full conversion including gas line upsizing, new venting, and proper commissioning.
Isolation valves installed on every unit for easy annual descaling.
Gas line verified and upsized if needed. Measured against actual BTU requirements.
Manufacturer-specified vent. Correct materials, sizing, and routing — no generic substitutions.
Isolation valves on every install. Standard, not optional.
Condensate drain properly routed and neutralized when required.
Combustion air verified. Matches unit type (direct-vent or non-direct-vent).
Pressure tested and fully commissioned. Unit must meet specifications before we leave.
Complete documentation handed over. Model, serial, configuration, and maintenance schedule.
A straightforward tank-to-tankless conversion typically takes 6 to 10 hours. More complex installs with gas line or vent work may extend to a second day.
Varies based on scope including gas line upsizing, venting, and electrical work. We quote based on actual conditions in your Mack home.
Best for high-demand households with long ownership horizons. We provide honest math for your specific situation.
A properly installed and maintained unit should last 20 years or more — roughly double a tank unit.
Annual descaling recommended for most Mack homes. More frequent with hard water.
Undersizing the gas line, wrong vent configuration, skipping isolation valves, incorrect sizing, ignoring water quality, and choosing price over proper installation are the most common errors that cause premature failure.
The install matters more than the unit brand. Get the install right and a quality tankless delivers decades of reliable service.
Considering a tankless conversion in Mack? Done right, it delivers two decades of efficient endless hot water. Done wrong, it disappoints from day one.
