FAQs
What advantages does a tankless water heater offer over a traditional storage-tank model?
Tankless units heat water on demand, which means you only pay to heat the water you actually use. This cuts standby heat loss and can reduce energy bills by 25–40 %. They also provide an endless supply of hot water, free up floor space because the unit mounts on a wall, and generally last five to ten years longer than tank models. Many systems qualify for efficiency rebates available to Guild homeowners, adding further savings.
How do I determine the correct size (flow rate) for my household in Guild?
Sizing is based on the total gallons per minute (GPM) of hot water your fixtures may require at the same time and the temperature rise between incoming cold water and desired outlet temperature. We add the GPM of all fixtures that could run simultaneously—e.g., a shower (2 GPM) plus a dishwasher (1.5 GPM) equals 3.5 GPM. In Guild, groundwater temperatures average about 50 °F, so for a 120 °F setpoint you need a 70 °F rise. Our technicians perform this calculation on-site and recommend a properly sized gas or electric unit so you never run out of hot water during peak use.
Will my existing gas line, venting, or electrical service need to be upgraded?
Possibly. Gas tankless models usually require a larger BTU input (150,000–200,000 BTU) and a ¾-inch gas supply line. If your current line is undersized, we’ll upsize it to ensure safe, efficient operation. Most units also need Category III or IV stainless-steel venting or outdoor-rated direct venting. Electric tankless heaters may need a 200-amp service and multiple dedicated 40- to 50-amp breakers. During our free estimate we inspect your home’s infrastructure and provide a detailed quote for any necessary upgrades so there are no surprises on installation day.
What does the installation process look like and how long will it take?
A standard retrofit in Guild takes 4–8 hours. We start by draining and removing the old tank, mounting the new tankless unit on the wall, and connecting water, gas, or electrical lines. Next we install proper venting or condensation drains, pressurize the system, and run performance tests. Finally, we walk you through the controls and maintenance steps. For complex gas line or electrical upgrades, the job may extend to a full day, but you’ll always have hot water back the same evening.
How much maintenance does a tankless water heater require?
Most manufacturers recommend a yearly service. This includes flushing the heat exchanger with a vinegar solution to remove mineral scale, cleaning the inlet screen filter, and checking the combustion or heating elements. In areas with hard water around Guild, installing a scale-reduction system or water softener can lengthen intervals between flushes. Routine maintenance protects your warranty and keeps efficiency high, so we offer affordable annual service plans to make it hassle-free.
What are the upfront costs, energy savings, and available incentives in Guild?
Installed costs typically range from $2,800 to $4,500 depending on size, fuel type, and any line upgrades. Although the initial investment is higher than a tank unit, homeowners usually save $80–$150 per year on energy, meaning the payback period can be as short as 4–6 years. Guild residents may qualify for up to a $300 federal tax credit under the Energy Efficient Home Improvement Credit and additional rebates from local utilities. We handle all paperwork and will apply any rebates directly to your invoice to lower your out-of-pocket cost.
