FAQs
What are the main benefits of switching to a tankless water heater?
Tankless (on-demand) heaters heat water only when you open a tap, eliminating standby losses associated with storage tanks. This typically cuts energy use by 25-40 %, provides a virtually endless supply of hot water, frees up floor space because the unit mounts on a wall, and often lasts 20+ years—about twice the life expectancy of a conventional tank. Many models also qualify for federal or local efficiency rebates.
How do I know what size or capacity tankless unit I need for my home?
Sizing is based on flow rate (gallons per minute, or GPM) and required temperature rise. Add up the simultaneous fixtures you expect to run—e.g., shower (2.0 GPM) + kitchen sink (1.5 GPM) + washing machine (2.0 GPM) = 5.5 GPM. Then calculate how much you need to raise incoming water (e.g., from 50 °F to 120 °F = 70 °F rise). A unit rated for at least 6 GPM at a 70 °F rise would cover that demand. Our technicians will perform this load calculation during your estimate to recommend the right model.
What maintenance does a tankless water heater require?
Most manufacturers call for an annual flush with white vinegar or a descaling solution to remove mineral buildup from the heat exchanger. Homes with very hard water may need service every 6 months or a water-softening system. You should also clean the inlet filter, inspect venting for blockages, and verify the pressure-relief valve is functioning. Routine maintenance keeps efficiency high and protects your warranty.
Can a tankless unit replace my existing tank heater without major changes?
In many cases yes, but several upgrades may be needed: (1) Gas units often require a larger ¾" gas line and Category III/IV stainless venting to handle higher BTU output. (2) Electric models need a dedicated 240 V circuit (or multiple circuits) with sufficient amperage. (3) A condensate drain line is required for high-efficiency units. (4) We may relocate water lines to meet clearance codes. During your in-home consultation we evaluate these factors and provide a fixed-price quote that covers all code-compliant modifications.
How long does installation take and will I be without hot water?
A typical retrofit takes 4–8 hours for gas models and 6–10 hours for electric, depending on venting and line upgrades. We remove the old tank, mount the new unit, run any new piping/wiring, and perform start-up testing. Your home will be without hot water only during the changeover window—usually a few hours—and we schedule installations at times convenient for you to minimize disruption.
Is a tankless water heater suitable for homes with hard water or poor water quality?
Tankless systems work fine with hard water but scale forms faster on the heat exchanger. If your water hardness exceeds 8–10 grains per gallon, we strongly recommend a whole-house softener or an inline scale-inhibiting filter. These devices dramatically reduce mineral buildup, improve efficiency, and extend the life of the heater. We can test your water during the estimate and propose the best treatment option.
