Know the Warning Signs
Is Your Tankless Heater Acting Up?
An on-demand water heater is a dependable appliance, but it will show signs of trouble when a component is failing. Don’t wait for a complete breakdown to call for help. If you notice any of these issues, it’s time to schedule a professional repair service to prevent further damage and more costly fixes.
Common warning signs include inconsistent hot water, a sudden drop in water pressure, unusual sounds like humming or clicking, visible leaks or corrosion around the unit, or an error code on the digital display. Ignoring these symptoms can lead to system failure, leaving you with no hot water when you need it most. Our technicians can quickly identify the root cause and provide a lasting solution.

A Modern, Efficient Solution
Why Switch to a Tankless System?
A traditional water heater constantly burns energy to keep a large tank of water hot, leading to wasted energy and higher utility costs. A tankless water heater, by contrast, only heats water when you turn on the tap. This on-demand functionality can reduce your water heating energy costs by up to 35%.
Beyond energy savings, tankless units are compact and wall-mountable, freeing up valuable floor space in your utility closet, basement, or garage. They also boast a lifespan of 20 years or more—nearly double that of a conventional tank heater. With endless hot water, lower bills, and a longer-lasting system, the advantages of going tankless are clear.
Protect Your Investment
Tankless Water Heater Maintenance
To ensure your tankless water heater operates efficiently and reliably for its entire 20+ year lifespan, regular professional maintenance is essential. Hard water minerals can build up inside the unit over time, restricting flow and reducing heating efficiency. Our comprehensive maintenance service keeps your system in pristine condition.
During a tune-up, our technicians perform a system flush to descale the heat exchanger, clean the filters, inspect all connections, and test the unit’s performance. This preventative service not only extends the life of your water heater but also ensures it runs at peak energy efficiency, saving you money on your monthly bills.
The Importance of Annual Tune-Ups
Why You Shouldn't Skip Maintenance
Skipping annual maintenance on your tankless system can lead to serious and expensive problems. Mineral scale buildup is the primary cause of component failure, forcing the unit to work harder to heat water, which increases energy consumption and strain on parts. Over time, this can lead to premature system failure and unexpected replacement costs.
An annual tune-up by Astacio is a small investment that pays for itself. It helps maintain your manufacturer’s warranty, prevents sudden breakdowns, and keeps your energy bills low. By catching and addressing minor issues early, we ensure you continue to enjoy the reliable, on-demand hot water you depend on every day.

Lower Bills, Better Performance
Maximize Your Energy Efficiency
One of the most compelling reasons to install a tankless water heater is the significant reduction in energy consumption. Traditional tank-style heaters suffer from standby heat loss—they constantly reheat water to keep it at a set temperature, even when you’re not using it. This is like leaving your car idling all day just in case you need to drive somewhere. It’s an enormous waste of energy that you pay for every month.
A tankless system completely eliminates standby heat loss. By heating water only when there’s a demand for it, these units operate with remarkable efficiency—often over 95%. For a typical family, this can translate into annual savings of hundreds of dollars on utility bills, allowing the investment in a new system to pay for itself over time.
Beyond the savings, this efficiency is better for the environment. By reducing your home’s energy consumption, you’re also lowering your carbon footprint. Choosing a high-efficiency tankless water heater from Astacio is a decision that benefits both your wallet and the planet, providing sustainable comfort for years to come.
Comfort & Convenience
Never Run Out of Hot Water Again
Remember the days of scheduling showers or spacing out laundry loads to avoid running out of hot water? With a tankless water heater, that inconvenience is a thing of the past. Because the system heats water on demand, the supply is continuous and unending. You can run the dishwasher, do a load of laundry, and have multiple family members take showers back-to-back without ever getting a blast of cold water.
This level of convenience transforms your daily routine. There’s no more waiting for a 40- or 50-gallon tank to refill and reheat. Hot water is available instantly, whenever you need it, for as long as you need it. This is especially beneficial for large families, homes with high-demand fixtures like soaking tubs, or anyone who simply values the comfort of a reliable hot water supply.
Furthermore, tankless systems deliver clean, fresh hot water every time. In a traditional tank, water sits for hours or days, allowing rust and sediment to accumulate at the bottom. Since a tankless unit heats water as it passes through, you’re always getting a fresh supply for bathing, cooking, and cleaning.
Ready for Endless Hot Water?
Whether you need an emergency repair, are considering an upgrade to a new tankless system, or want to schedule routine maintenance, our team is here to help.

Got Questions?
Your Tankless Water Heater Questions, Answered
Making the switch to a tankless water heater is a big decision, and it’s natural to have questions. We’ve compiled answers to some of the most common inquiries we receive from homeowners in the Norwalk area to help you make an informed choice.
How much does a tankless water heater cost?
A tankless water heater has a higher upfront cost than a traditional tank model, but it provides significant long-term savings on energy bills and has twice the lifespan. We provide free, detailed estimates based on the right model for your home and the specific installation requirements.
Are tankless water heaters worth it in Connecticut?
Absolutely. With high energy costs in Connecticut, the monthly savings from an energy-efficient tankless system provide a fantastic return on investment. They also perform reliably in cold climates, providing endless hot water even on the coldest winter days.
How long do tankless water heaters last?
With proper annual maintenance, a quality tankless water heater can last 20 years or more. This is nearly double the average 8-12 year lifespan of a traditional tank-style heater, making it a much better long-term value.
What kind of maintenance do they require?
To ensure longevity and efficiency, tankless water heaters should be professionally serviced once a year. The main task is flushing the system to remove mineral deposits (descaling), which is especially important in areas with hard water. Our maintenance service also includes cleaning filters and inspecting all components.
Can any plumber install a tankless water heater?
Installation is more complex than a standard water heater and requires specific training in sizing, venting, and gas or electrical configuration. It is crucial to hire a licensed and experienced plumber, like the team at Astacio, to ensure a safe and code-compliant installation.
