What affects the price
The final price for a new water heater depends on a few moving parts. First, you have to choose the right fuel source—gas or electric—and decide if you want to stick with a standard tank or upgrade to a tankless model. We also look at the physical space where it sits and whether your current venting or gas lines meet modern safety codes. If we need to move the unit or upgrade plumbing to get it up to speed, that shifts the labor involved. Exact pricing confirmed free on the call.
About this service
Rinnai systems provide on-demand hot water, but internal components like flow sensors or igniters can eventually wear down. If your unit is making unusual sounds or failing to provide steady heat, it is time for a professional assessment. We identify the root cause of the performance drop to restore your system’s efficiency. Costs vary based on the specific part replacement needed. Exact pricing confirmed free on the call.
While you might not think about hot water as much in the summer, it is a great time to evaluate your system’s health. Because the incoming groundwater is warmer, your heater doesn't have to work as hard, making it a stress-free window to replace an aging unit before you hit the busy autumn season.
Frequently asked in Fort Collins
How long do hot water heaters typically last?
Tankless water heaters, like Rinnai models, generally have a longer lifespan than traditional tank heaters, often lasting 15 to 20 years. Proper maintenance in the Fort Collins climate, including regular flushing to prevent mineral buildup, is crucial for maximizing their service life. Following the manufacturer's guidelines will help ensure optimal performance.
What is the average cost of putting in a water heater?
What is the most efficient type of water heater?
Tankless water heaters are generally considered the most efficient option for homes in Fort Collins. They heat water only when you need it, eliminating the energy waste associated with keeping a large tank hot constantly. This on-demand heating system can lead to substantial savings on your energy bills. Condensing tankless models offer even higher efficiency.
What are signs I need a new water heater?
Signs that your water heater in Fort Collins may need replacement include a noticeable reduction in hot water supply, unusual noises such as banging or popping, or visible rust and leaks around the unit. If your current heater is over 10-15 years old, it's wise to consider an upgrade. An increase in your utility bills could also indicate inefficiency.
What is the most common problem with a hot water heater?
For tankless units, mineral buildup is a frequent issue, especially in areas with hard water, which can impact performance. Ignition failures, where the unit doesn't heat the water, are also common. Error codes displayed on the unit often point to specific malfunctions that experienced technicians can quickly diagnose and fix. Regular maintenance helps prevent these issues.
Is it worth it to repair a hot water heater?
Repairing a water heater in Fort Collins is often a cost-effective solution, especially for newer or moderately aged units. Addressing issues like a faulty igniter or a minor leak is usually less expensive than a complete replacement. However, if your heater is old and requires frequent, costly repairs, a new unit might be the better long-term investment. A professional can help you decide.
