Water Heater Replacement FAQ — Longmont, CO

Common questions about water heater replacement in Longmont.

How do I know when to replace my water heater in Longmont?

Replace your water heater in Longmont when it is over 10 to 12 years old, produces rusty or discolored water indicating internal corrosion, leaks from the tank body, requires frequent repairs, or no longer meets your household hot water demand. A water heater approaching these conditions often fails unexpectedly — replacement before failure avoids an emergency.

Should I get a tank or tankless water heater in Longmont?

Tank water heaters cost less upfront and are simpler to install. Tankless units provide endless hot water on demand and typically have lower operating costs, but cost more initially. For most Longmont families, a quality tank unit in the correct size is the most cost-effective choice. Our plumbers help you compare the total cost of ownership for your specific situation.

How much does water heater replacement cost in Longmont, CO?

Water heater replacement in Longmont typically costs $800 to $1,800 for a standard tank unit including the heater and installation labor. Tankless water heater installation costs $1,500 to $3,500 depending on the unit and installation complexity. Phoenician Plumbing provides free replacement estimates so you can make an informed decision about unit type and budget.

What size water heater do I need for my Longmont home?

For a tank water heater, the right size depends on the number of occupants: 30 to 40 gallons for 1 to 2 people, 40 to 50 gallons for 3 to 4 people, and 50 to 80 gallons for larger households. For tankless units, the required flow rate in GPM determines the correct unit size. Phoenician Plumbing assesses your household demand and recommends the right unit for your Longmont home.
