Water Heater FAQs
Common Water Heater FAQs in Longmont, CO
At Homerun Heating & Air, we understand that having a reliable water heater is essential to the comfort of your home or business. Whether you’re dealing with inconsistent hot water, rising utility bills, or you’re unsure when to replace your unit, we’re here to help. We’ve compiled a list of the most frequently asked questions from homeowners and businesses in Longmont, CO, to give you the knowledge and confidence you need to make informed decisions about your water heater system. If you’re looking for expert advice, reliable service, or just curious about how water heaters work, we’ve got your answers covered—right off the bat.
1. How long does a water heater typically last?
Most traditional tank water heaters last about 8–12 years, while tankless water heaters can often last up to 20 years with proper maintenance. The actual lifespan depends on several factors, including water quality, usage habits, and whether or not the unit receives regular servicing. In Longmont, where hard water can be an issue, sediment buildup may shorten the lifespan if not addressed. Performing annual maintenance like flushing the tank and inspecting the anode rod can greatly extend the life of your unit. If your water heater is nearing the 10-year mark, it may be time to consider replacement options before you’re left without hot water.
2. What size water heater do I need for my home?
Choosing the right size water heater depends on your household size and hot water usage habits. For a family of four, a 40–50 gallon tank is typically sufficient. If you frequently run multiple appliances at once—like a dishwasher, washing machine, and shower—a larger tank or a tankless system might be more appropriate. In commercial applications or larger homes in Longmont, CO, it’s best to consult with a professional to assess your exact hot water demand. Our team at Homerun Heating & Air can help calculate the proper capacity to ensure you never run out of hot water.
3. Should I repair or replace my water heater?
It depends on the age of the unit and the extent of the damage. If your water heater is less than 8 years old and has a minor issue—such as a faulty thermostat or heating element—repairing it may be the most cost-effective option. However, if it’s older and experiencing frequent issues or leaking from the tank itself, replacement is usually the better long-term solution. At Homerun Heating & Air, we offer free estimates and expert inspections to help you make an informed decision that fits your budget and household needs.
4. What are the signs my water heater is going bad?
Common warning signs include inconsistent or no hot water, strange noises from the tank, rusty water, or water pooling around the base of the heater. High energy bills and frequent pilot light issues are also red flags. If you notice any of these symptoms, it’s time to schedule an inspection before the issue becomes a full-blown emergency. In Longmont, where seasonal temperature swings can put extra stress on plumbing systems, it’s especially important to stay on top of early signs of trouble. We recommend checking your water heater regularly and scheduling yearly maintenance.
5. Are tankless water heaters better than traditional tank models?
Tankless water heaters are highly energy-efficient and provide hot water on demand, which makes them a great choice for households looking to reduce energy costs. They also have a longer lifespan—typically around 20 years. However, they come with a higher upfront cost and may not be suitable for homes with high simultaneous hot water usage unless multiple units are installed. Traditional tank water heaters are more affordable initially and are ideal for standard household needs. At Homerun Heating & Air, we help homeowners weigh the pros and cons of each system based on their lifestyle, home size, and budget.
6. How much does it cost to install a new water heater?
The cost of installing a new water heater in Longmont, CO, varies depending on the type (tank or tankless), size, brand, and complexity of the installation. On average, homeowners can expect to pay between $1,000–$3,500 for a new system, including labor. Tankless systems tend to be on the higher end of that range due to the added installation complexity. We offer free estimates at Homerun Heating & Air, and our technicians are happy to walk you through all available options to find the best fit for your needs and budget.
7. How often should I flush my water heater?
Flushing your water heater once a year is recommended to remove sediment and mineral buildup—especially in areas like Longmont, where hard water is common. Sediment can cause your water heater to work harder, reducing efficiency and shortening its lifespan. Flushing the tank helps maintain energy efficiency and consistent water temperatures. If you hear rumbling or popping noises, that’s usually a sign your water heater needs flushing. Don’t feel comfortable doing it yourself? No problem—we offer affordable water heater maintenance services that take care of everything for you.
8. What is the energy efficiency rating on water heaters
The energy efficiency of a water heater is measured by its Uniform Energy Factor (UEF). The higher the UEF, the more efficient the unit. Tankless models usually have higher UEF ratings compared to tank models. ENERGY STAR® certified water heaters meet strict energy efficiency guidelines and can significantly reduce your utility bills. You can learn more about water heater efficiency from the ENERGY STAR website. At Homerun Heating & Air, we carry a wide selection of high-efficiency water heaters and can help you find the right model for your home or business.
9. Can I install a water heater myself?
While it’s technically possible to install a water heater yourself, it’s not recommended unless you have plumbing and electrical experience. Incorrect installation can lead to leaks, gas line issues, code violations, or even personal injury. In Longmont, local plumbing codes must be followed and permits are often required. Hiring a licensed and insured professional like Homerun Heating & Air ensures your system is installed safely and correctly. We also handle the required inspections and paperwork, so you don’t have to.
10. Why is my water heater making noise?
Water heater noises—such as rumbling, popping, or hissing—are usually caused by sediment buildup at the bottom of the tank. As the water heats, trapped sediment can cause the water to boil or create air pockets, leading to these sounds. While it may not seem like a big issue at first, it can cause long-term damage and lower energy efficiency. Flushing the tank can usually resolve the problem. If noises persist after flushing, give us a call to inspect the system and ensure nothing more serious is going on.
11. What temperature should my water heater be set to?
The U.S. Department of Energy recommends setting your water heater to 120°F for optimal efficiency and safety. This temperature is hot enough to provide comfortable showers and clean dishes while reducing the risk of scalding and saving energy. Some homeowners increase the temperature slightly for specific needs, but anything above 130°F can increase the risk of burns and energy waste. Need help adjusting your water heater’s thermostat? We can handle that during a routine service call or maintenance visit.
12. Why is my hot water running out so fast?
If your hot water supply doesn’t last as long as it used to, it could be due to sediment buildup in the tank, a failing heating element, or a water heater that’s too small for your household. Another common issue is a broken dip tube, which causes cold water to mix with hot water prematurely. Our team at Homerun Heating & Air can diagnose the problem and offer the right solution, whether it’s a quick repair or upgrading to a more suitable unit. Don’t let short showers ruin your day—give us a call!
13. How do I know if my water heater is under warranty?
You can usually find your water heater’s warranty information on the label attached to the tank or by checking the manufacturer’s website using the model and serial number. Most standard water heaters come with a 6–12 year warranty, but extended warranties may be available. At Homerun Heating & Air, we help customers determine warranty coverage during service calls and offer guidance on manufacturer claims if your unit is still protected. Keep all paperwork and receipts in a safe place to make the process smoother.
14. Are there any rebates for upgrading to an energy-efficient water heater?
Yes! Longmont residents may qualify for rebates and incentives through local utility companies or federal programs when they upgrade to an ENERGY STAR® certified water heater. These rebates can significantly offset the cost of a high-efficiency unit. Visit the Department of Energy’s website for updated rebate and tax credit information. Our team stays informed on current offers and can help you navigate the rebate process when upgrading your system.
