FAQs
How does a tankless water heater work and what benefits does it offer over a conventional tank?
Instead of storing 40–50 gallons of pre-heated water, a tankless unit uses high-output gas burners or electric elements to heat water only when you open a hot-water tap. Because it is on-demand, it eliminates standby heat loss, delivers an endless supply of hot water, frees up floor space, and can cut water-heating energy use by 25–40 %. Many Madisonville homeowners see their monthly natural-gas bills drop noticeably after switching.
Is a tankless water heater a good fit for Madisonville’s water quality and climate?
Yes. Our area’s relatively mild winters mean incoming water temperatures are not as cold as in northern states, so a mid-range tankless unit can usually meet a whole-house demand without oversizing. Madisonville’s water hardness averages 6–9 grains per gallon—moderately hard but manageable. During installation we include a scale-inhibiting filter or annual flush service to prevent mineral buildup and keep the heat exchanger efficient.
What size (flow rate) tankless water heater do I need for my home?
Sizing is based on two factors: 1) the total gallons-per-minute (GPM) you expect to use at one time, and 2) the temperature rise required (difference between incoming cold water and desired hot water). A typical Madisonville household needs a 7–9 GPM gas unit to run two showers and a dishwasher simultaneously, while a smaller condo may need only a 4 GPM model. During our free in-home consultation we calculate your peak demand and incoming water temperature to recommend the properly sized unit—preventing both cold-water “sandwiches” and wasted fuel.
What is involved in the installation process and how long will it take?
Most conversions from a tank to a gas tankless heater take one working day. We: • Shut off water, gas, and electricity to remove the existing tank. • Install a mounting bracket on the wall (usually in the same utility room or garage). • Upgrade gas line and add a Category III/IV stainless or PVC vent through an exterior wall or roof. • Connect cold- and hot-water lines with isolation valves for future maintenance. • Add a condensate drain and, if needed, a condensate pump. • Flush, pressure-test, and commission the unit, then teach you how to use the digital controller. Electrical tankless models may require a panel upgrade and can take 1–2 days.
What ongoing maintenance does a tankless water heater require?
To maintain efficiency and warranty coverage, manufacturers recommend: • Annual or bi-annual descaling/flush with a vinegar solution (we can perform this in about an hour). • Cleaning the inlet water filter every 6–12 months. • Checking the condensate drain and vent for obstructions. Because there is no large tank, you avoid the risk of tank corrosion and major leaks, but staying on the simple maintenance schedule can help the heat exchanger last 20+ years—roughly double the life of a storage-type heater.
How much does a tankless installation cost in Madisonville, and are there rebates or incentives?
Installed prices run $2,800–$4,500 for most gas units, depending on capacity, gas-line upgrades, and venting complexity; premium condensing models are at the top of that range. Electric tankless systems are often less up-front ($1,200–$2,000) but may require a costly electrical service upgrade. Federal tax credits of 30 % up to $600 are available for ENERGY STAR-certified units, and Entergy Louisiana occasionally offers $250 rebates for high-efficiency gas appliances. With the energy savings (average 15–20 % of total household gas use) most homeowners break even in 5–7 years, after which the lower utility bills are pure savings.
