FAQs
What are the primary benefits of installing a tankless water heater in a Rockford home?
Tankless (on-demand) systems heat water only when you open a tap. That means no standby heat loss, virtually unlimited hot water, and units that are roughly the size of a suitcase—freeing up floor space. Because they run at 95 %+ efficiency, most households see energy-use reductions of 25–40 % compared with storage-tank heaters. Tankless models also last 18–20 years—about twice the lifespan of a conventional tank—so you save on both utilities and replacement costs.
How much can I expect to save on energy bills in Rockford with a tankless unit?
Actual savings vary with family size and water-use habits, but Rockford customers usually lower gas consumption by 150–250 therms per year. At current Nicor Gas rates of roughly $1.10 per therm, that equates to $165–$275 in annual utility savings. Over a 20-year life, the payback can exceed $3,000, not including potential $300–$500 state or utility rebates available for ENERGY STAR® certified models.
Will a tankless water heater provide enough hot water for my entire household?
Yes—if it is sized correctly. Instead of storing 40–50 gallons, a tankless unit heats water as it flows through the heat exchanger. As long as the unit’s flow-rate capacity (measured in gallons per minute, or GPM) exceeds the combined demand of your fixtures—showers, dishwasher, washing machine—hot water will be continuous. During your estimate we calculate your peak simultaneous demand and incoming-water temperature (groundwater in Rockford averages 50 °F) to select a model that delivers the needed GPM at a comfortable 120 °F outlet temperature.
How do I determine the right size tankless water heater for my Rockford home?
Sizing is based on two factors: 1) peak flow rate and 2) required temperature rise. We add up the GPM of fixtures likely to run at the same time—e.g., two showers (2.0 GPM each) plus a kitchen sink (1.5 GPM) equals 5.5 GPM. Next we calculate temperature rise: desired output temp (120 °F) minus average incoming temp (50 °F) equals 70 °F rise. A unit rated at 6–7 GPM at a 70 °F rise will meet that demand. Our technicians perform this calculation on-site, factoring in winter groundwater temps, gas line capacity, and venting options to recommend the optimal unit.
How long does installation take and will my existing plumbing need major alterations?
Most residential replacements are completed in one day. We mount the compact tankless unit on a wall, run stainless-steel or PVC venting through an exterior wall or roof, and upgrade the gas line if necessary (tankless burners draw up to 199,000 BTU/h). Copper or PEX water lines tie into your existing plumbing with minimal disruption, and we install a condensate drain for high-efficiency models. Because units are wall-hung, you regain the floor space occupied by the old storage tank.
What maintenance is required for a tankless water heater and how long will it last?
Annual maintenance keeps efficiency high and preserves the warranty. We recommend a 45-minute flush with food-grade white vinegar or a manufacturer-approved descaling solution to remove mineral buildup caused by Rockford’s moderately hard water (10–12 grains per gallon). The burner and air intake filters are also inspected and cleaned. With proper care, most tankless heat exchangers carry 12- to 15-year warranties and routinely deliver 18–20 years of reliable service—far longer than the 8–12 years typical for tank heaters.
