Fort Collins Water Heater Installation — Tank and Tankless
Bluewave installs both tank and tankless units running on gas and electric power. We pull the required permit and perform the post-install inspection — all in one visit for most standard jobs. For tankless conversions, we handle the gas line or electrical upgrade the new unit requires.
We are a plumbing-only company. Licensed Colorado plumbers, same day available for tank replacements. If your existing unit has a problem that might be repairable, see our water heater repair page first.

We stock the most common tank sizes and can usually complete a straightforward replacement the same day. Tankless conversions take a full day and are typically scheduled for the next available morning.
Signs It Is Time to Replace Your Fort Collins Water Heater
If you are seeing any of the following, you are past the repair stage. If you have an existing unit with a problem that might be repairable, visit our water heater repair page first.
-
The tank body is leaking from the bottom or sides.
Internal corrosion that has reached the tank wall is not repairable. A leaking tank body means the unit needs to come out.
-
The unit is 12 or more years old in Fort Collins hard water conditions.
Failing, struggling to recover, or failing repeatedly despite repairs — Fort Collins hard water shortens a rated 10 to 12 year tank lifespan to 6 to 9 years without a softener.
-
You are getting rusty or discolored water.
Even after the pipes have been ruled out as the source. Rust inside the tank means the tank is corroding from the inside.
-
Repair cost was quoted at more than half the cost of a new unit.
At that point a new unit is a better investment than extending the life of an old one.
-
The unit is 15 or more years old.
At that age in Fort Collins water conditions, the unit is on borrowed time. Replacement now, on a schedule you control, is better than an emergency replacement when the tank lets go.
-
You want to upgrade from a tank unit to an on-demand tankless system.
The best time to make the switch is before the old unit fails so you can plan the right installation instead of rushing it.
Fort Collins hard water shortens a rated 10 to 12 year tank lifespan to 6 to 9 years without a softener. Past 10 years with any of the signs above, call now.
Tank or Tankless — Which Water Heater Is Right for Your Fort Collins Home?
The honest answer depends on your home, your budget, and how long you plan to stay. Here is how we think through it.
A tank water heater is right when:
-
Budget is the primary factor. A tank replacement runs $1,200 to $2,200 installed in Fort Collins. A tankless conversion runs $2,500 to $4,500, more if the gas line needs upgrading.
-
You need same day hot water today. Tank replacements are available same day for most standard sizes. Tankless conversions require a site assessment and a scheduled installation day.
-
The existing gas or electric connections do not need upgrading. A like-for-like tank swap is the fastest and most straightforward installation.
-
Hot water demand is moderate and running out is not a regular problem.
A tankless water heater is right when:
-
You want on-demand hot water without running out. Tankless units heat water as it flows through the unit. There is no tank to deplete.
-
Energy efficiency matters to you. Tankless units typically use 20 to 30 percent less energy than a tank unit for the same household size.
-
You plan to stay in the home long term. Tankless units last 15 to 20 years in Fort Collins conditions with proper maintenance, versus 6 to 9 years for tanks in hard water without a softener.
-
You already have a water softener or plan to install one. A water softener paired with a tankless unit is the best long-term combination for Fort Collins water conditions — the softener protects the heat exchanger and extends the service interval between descalings.
⚠️ Fort Collins hard water note: Annual descaling is a requirement for tankless units in this market, not an option. The Cache la Poudre mineral load is among the highest in Northern Colorado. Factor that into the long-term comparison.
Is a tankless water heater worth it in Fort Collins?
For most homeowners who plan to stay long term, yes. Tankless units last 15 to 20 years in Fort Collins conditions with proper maintenance, compared to 6 to 9 years for tanks in this hard water market. They cost more upfront and need annual descaling due to the Cache la Poudre mineral load. Paired with a water softener, a tankless unit is the best long-term investment for this market.
Tankless Water Heater Installation in Fort Collins — What to Expect
If you are considering a tankless upgrade, here is exactly what the installation involves so you know what to expect before you call.
-
Site assessment first.
We assess the existing gas line or electrical supply, the current venting configuration, available wall space, and access before recommending a unit size or brand. What works in one Fort Collins home may not be feasible in another without additional work.
-
Gas line upgrade for most conversions.
Most gas tankless units draw significantly more BTUs than a tank unit. The existing half-inch gas supply line in many Fort Collins homes is too small. Upgrading to a three-quarter-inch line is part of the standard tankless conversion and is included in our quote.
-
Sizing with a Fort Collins hard water buffer.
We size one to two gallons per minute higher than national calculators suggest because scale buildup in the heat exchanger reduces effective flow rate over time in hard water conditions.
-
Cold incoming water temperature in Northern Colorado winters.
Fort Collins incoming water drops to around 40 to 45 degrees in winter. Undersized units struggle during winter peak demand. We size for the coldest months, not the average.
-
Venting the unit.
Most modern gas tankless units are direct vent — they draw combustion air from outside and exhaust through a dedicated wall or roof penetration. We handle the venting run as part of the installation.
-
Permit from Larimer County or the City of Fort Collins.
All water heater installations require a mechanical permit. We pull it, schedule the required inspection, and coordinate everything. You do not have to manage any of the permit process.
What does it cost to switch from a tank to a tankless water heater in Fort Collins?
A tankless conversion in Fort Collins typically runs $2,500 to $4,500 installed, including the unit, venting, and permit. If the existing gas line needs upgrading, add $300 to $800. Rinnai and Navien are the most commonly installed brands here. We give you a written quote after the site assessment, before any work starts.

Sizing a Water Heater for Fort Collins Water and Climate
Hard water and cold winters both affect real performance versus what the spec sheet says. Here is what we account for in Fort Collins.
-
Hard water reduces effective tank capacity.
Sediment accumulates at the tank base from Fort Collins hard water. A 50-gallon tank delivers closer to 40 to 45 gallons per cycle after a few years without flushing. We recommend annual flushing to preserve capacity.
-
Size tankless units with a hard water buffer.
Scale builds inside a tankless heat exchanger over time. We size tankless units one to two gallons per minute above national calculator results for Fort Collins conditions, so the unit delivers full performance as it ages.
-
First hour rating is more useful than tank size.
The first hour rating tells you how much hot water a tank unit delivers in its first hour of peak use. A 50-gallon tank with a fast recovery element often outperforms a 75-gallon tank with a slower one in the same household.
-
Cold incoming water in Northern Colorado winter.
Fort Collins incoming water drops to around 40 to 45 degrees in December and January. A tankless unit sized for 60-degree incoming water will underperform on cold mornings. We size for the coldest months, not the annual average.

Fort Collins Water Heater Installation Questions
My water heater failed last night and I have no hot water. Can you install a new one today?
In most cases yes for standard tank replacements. Call (970) 997-1528 and we confirm same day availability on the first call. We stock the most common sizes and can usually complete a straightforward tank replacement the same day you call. Tankless conversions take longer and are scheduled for the next available morning.
How long does water heater installation take?
A standard tank replacement takes two to three hours from arrival to completion in most Fort Collins homes. A tankless conversion takes a full day in most cases, longer if gas line or venting work is also required. We give you a realistic timeline in writing before we schedule the installation.
Do I need a permit to replace my water heater in Fort Collins?
Yes. Water heater installation requires a mechanical permit through the City of Fort Collins Building Services or Larimer County depending on your address. We pull the permit, schedule the inspection, and handle all coordination. Unpermitted water heater installations create problems at resale and with home insurance claims.
What size tankless water heater do I need for my Fort Collins home?
Sizing depends on your peak demand — how many fixtures you run simultaneously — and Fort Collins water temperature, which drops to around 40 degrees in winter. We size units with a hard water buffer because scale buildup reduces effective flow rate over time. We assess your home before recommending a size, not after.
Can you replace a gas tank unit with a gas tankless water heater?
Yes. In most cases the existing gas line needs to be upgraded from a half-inch to a three-quarter-inch supply line to meet the higher BTU demand of a tankless unit. We assess the existing supply, handle the upgrade if needed, install the unit, and pull the permit. Most conversions are a one-day job.
Do you install electric tankless water heaters in Fort Collins?
Yes, though electric tankless units require a significant electrical panel upgrade in most homes — typically 240V circuits at 150 to 200 amps. We assess the existing panel capacity before recommending one. For most Fort Collins homes with natural gas service, a gas tankless unit is the more practical and cost-effective choice.
How long does a new water heater last in Fort Collins?
A tank water heater lasts 6 to 9 years in Fort Collins homes without a water softener, due to hard water from the Cache la Poudre. With a softener and annual flushing, closer to 10 to 12 years. A properly maintained tankless unit lasts 15 to 20 years. A water softener is the single best investment for extending any water heater's life in this market.
Can I schedule a tankless installation in advance rather than waiting for the old unit to fail?
Yes, and that is the better approach. A planned tankless conversion lets us size the unit correctly, assess the gas line and venting at your pace, and schedule the installation without the pressure of an emergency. Most Fort Collins homeowners who upgrade to tankless do it when the old unit starts showing signs of age, not after it fails.
