FAQs
What are the main advantages of installing an on-demand (tankless) water heater in a Cleveland home?
Tankless units heat water only when you open a tap, eliminating stand-by heat loss from a storage tank. This can cut water-heating energy use by 24–34 %, lower utility bills, and free up floor space. Because they never “run out” of hot water, they’re great for large families or back-to-back showers. Tankless heat exchangers are usually stainless steel or copper, giving them a life expectancy of 20+ years—roughly twice that of a conventional tank. In Northeast Ohio’s cold winters, they also reduce the risk of basement flooding caused by a ruptured tank.
How can I tell if a tankless water heater is the right choice for my Cleveland property?
A tankless unit is ideal if you have limited space, want lower gas/electric bills, plan to stay in the home for at least 5 years, or need high volumes of continuous hot water (e.g., large families, soaking tubs). Homes with natural gas service and ¾-inch gas lines already in place can convert easily, while electric-only homes may require a panel upgrade. Our technicians offer free in-home assessments: we test incoming water temperature (typically 45–50 °F in Cleveland), inspect venting paths, and verify that water flow rates meet manufacturer specs. If your peak demand exceeds ~9 gpm, a hybrid or multiple-unit cascade may be recommended.
What size or capacity tankless unit will I need?
Sizing is based on two factors: (1) your household’s peak simultaneous flow rate and (2) the required temperature rise. In Cleveland, incoming water can be as low as 40 °F in winter. To deliver 120 °F water, the unit must raise the temperature by 80 °F. For example, a shower (2.0 gpm) plus a dishwasher (1.5 gpm) running together equals 3.5 gpm. You’d choose a unit that can deliver at least 3.5 gpm at an 80 °F rise—typically a 160–180 k BTU natural gas model. Our plumbers measure your fixtures’ flow rates and use manufacturer sizing charts to ensure adequate performance year-round.
How long does installation take and what should I expect on the day of service?
Most single-unit gas installations are completed in one business day. We begin by shutting off utilities, draining and removing your old tank, and checking for code-compliant gas shut-offs, expansion tanks, and venting. We mount the new unit on a wall, upsize gas lines if necessary, install stainless-steel or PVC venting through an exterior wall or roof, and add a condensate neutralizer for high-efficiency models. Finally, we flush the system, test for leaks, and register the warranty. You’ll have hot water again the same day; total downtime is typically 4–6 hours.
What does a tankless installation cost in the Greater Cleveland area, and are there any rebates or tax incentives?
Installed pricing varies with fuel type, capacity, and any gas-line or electrical upgrades required, but most homeowners spend $3,200–$4,800 for a 160-199 k BTU natural gas unit fully installed. High-efficiency models (≥0.95 UEF) may qualify for a $200 rebate from Dominion Energy Ohio and up to a $600 federal tax credit under the Inflation Reduction Act (Section 25C). We handle all rebate paperwork and provide itemized invoices to make claiming incentives easy.
What maintenance is required for a tankless water heater in Cleveland’s water conditions?
Cleveland’s municipal water is moderately hard (110-140 ppm). To prevent mineral scaling in the heat exchanger, manufacturers recommend an annual vinegar or citric acid flush. During our annual tune-up we: (1) descale the heat exchanger, (2) clean the inlet water filter, (3) inspect the combustion chamber and venting, (4) check gas pressure and CO levels, and (5) update firmware on electronic controls. Proper maintenance keeps efficiency high and protects your warranty; a neglected heat exchanger can fail and is not covered if scaling is evident.
