FAQs
What are the main benefits of switching to a tankless water heater in Grandview?
Tankless units heat water on-demand, so you eliminate standby heat loss from a storage tank and can save 20–40 % on annual water-heating costs. In addition, the compact wall-mounted design frees up floor space, you get an unlimited supply of hot water (flow-rate permitting), and the life expectancy—20+ years—is nearly double that of most tank models. Tankless systems also qualify for federal tax credits and Evergy or Spire utility rebates that are available to Grandview homeowners.
How do I determine the correct size (gallon-per-minute rate) for my home?
Sizing is based on two factors: (1) the peak hot-water demand in gallons per minute (GPM) when multiple fixtures run at once, and (2) the temperature rise required—Grandview’s incoming water temperature averages 54 °F, so reaching a 120 °F set point requires a 66 °F rise. We add up the GPM of the fixtures you want to use simultaneously (e.g., shower 2.0 GPM + dishwasher 1.5 GPM) and choose a unit that can deliver that flow at a 66 °F rise. During a free in-home estimate we’ll perform these calculations and recommend a properly sized gas or electric model.
Will my gas line or electrical service need upgrades?
Most high-output gas tankless heaters draw 150,000–199,000 BTU/h—much higher than a standard 40-gal tank. If your existing natural-gas line is under-sized (commonly ½-in.), we may need to run a dedicated ¾-in. or 1-in. line from the meter. Electric tankless units often require 120–160 amp draw, which can exceed the capacity of a 100-amp panel. During our site visit we measure line pressure, pipe size, and panel load; if an upgrade is needed, we’ll provide a turnkey quote that includes gas piping, venting, condensate drain, or panel/service upgrade so there are no surprises.
How long does a typical tankless water heater installation take?
A straight swap in the same location with adequate gas, vent, and electrical supply usually takes 4–6 hours. If we have to relocate the heater, upsize gas piping, or install new vent penetrations through brick or siding, the job may run 8–10 hours or be split over two days. We arrive with all permits in hand, protect work areas with drop cloths, handle disposal of the old tank, test for gas leaks, and commission the unit per manufacturer specs before we leave.
Do I need a permit to install a tankless water heater in Grandview, and who handles inspections?
Yes. The City of Grandview requires a mechanical (and sometimes plumbing) permit for any water-heater replacement. Gas work must comply with the 2018 International Fuel Gas Code, and venting must meet manufacturer UL-listed specs. Our licensed master plumbers pull the permit, schedule both rough-in (if needed) and final inspections with the Grandview Building Department, and provide you with a copy of the signed-off permit card for your records.
What maintenance is required after installation, and do you offer service plans?
To keep the heat exchanger free of mineral buildup, manufacturers recommend a yearly flush with a 5-gallon vinegar solution—especially important with Grandview’s moderately hard (7–10 grains) water. We install isolation valves to make this procedure simple. In addition, the inlet screen filter should be cleaned every 6–12 months, and the combustion chamber inspected for debris. We offer affordable annual service plans that cover flushing, filter cleaning, gas-pressure check, and firmware updates, which not only maintain warranty coverage but also ensure peak efficiency and long unit life.
