We Help You Choose the Right Unit and Get It Installed Properly
Most homeowners replace a water heater twice in their lives. It’s not a purchase you want to rush, guess at, or leave to whoever shows up fastest with the cheapest box. The wrong unit — undersized, mismatched to your fuel source, or not suited to how your home is built — will cost you more in energy and repairs than the upfront savings are worth.
At Garden City Plumbing & Heating, we start with your home: how many people, how much hot water you actually use, what fuel source you’re working with, and whether your existing setup can support an upgrade. Then we recommend what makes sense — and install it correctly, the first time.
We service all types of water heaters

✓⃝ Electric tank water heaters

What Does Water Heater Installation Cost in Missoula?
Water heater installation costs vary more than most homeowners expect — and the difference isn’t random. The unit itself, how your home is set up, what type of system you’re moving to, and the complexity of the install all play a significant role. What we can promise is a clear, itemized quote before we start, so you know exactly what you’re agreeing to.
Here’s what actually drives the cost of a water heater installation:
Type of system
Tank units are generally less expensive to install than tankless or heat pump systems, which may require additional infrastructure changes or electrical upgrades.
Size and capacity
A unit sized for a household of two is a different cost than one built for a large family. Right-sizing matters for performance and long-term energy costs.
Fuel type
Gas and electric installations have different requirements. Switching fuel sources adds complexity — new lines, updated connections, and code compliance work.
Existing infrastructure
A straightforward swap into an existing setup costs less than an install that requires new venting, updated electrical panels, or modified plumbing lines.
Location in the home
Accessible utility rooms are simpler than cramped crawlspaces or attic installs. Where the unit lives affects how long the job takes.
Removal of old unit
We handle haul-away of your old water heater. Disposal of older units, especially those with certain materials, may factor into overall cost.
The best move before committing to any unit is a conversation with one of our technicians. We’ll look at your home, walk you through your options honestly, and give you a quote that reflects what the job actually involves — not a lowball number that grows after we start.

Garden City’s Water Heater Installation Process
A water heater installation isn’t just a swap — it’s a decision that affects how your home runs for the next 10–20 years. Here’s how we make sure it’s done right.

2
On-site assessment and recommendation
A certified technician visits your home, evaluates your existing setup, and asks the right questions — household size, usage patterns, fuel preference, budget. From there we recommend the unit that actually fits your home, not the one with the best margin. If you’ve already chosen a unit, we’ll tell you honestly if it’s the right call.
3
Clear quote before anything starts
You’ll get a full, itemized quote covering equipment, labor, any required infrastructure changes, and old unit disposal. No surprises after we start. You approve everything before we move forward.

5
Full system test and walkthrough
Before we leave, we run the system through a complete test — checking water temperature, pressure, connections, safety valves, and any smart controls if applicable. We walk you through how your new unit operates and what to watch for.
6
Warranty documentation and long-term support
We follow manufacturer guidelines to protect your equipment warranty and provide all documentation you need. Our VIC Maintenance Program can keep your new system running at peak performance for years to come — with priority scheduling and annual check-ins built in.
Considering tankless? Tankless units cost more upfront but typically last 5–8 years longer than traditional tanks and use significantly less energy. We can walk you through a real cost-over-time comparison so you’re making an informed decision — not just a cheaper one today.

Frequently Asked Questions
How do I know when it’s time to replace my water heater?
Most water heaters last 8–12 years. Signs it’s time to replace include frequent repairs, rusty or discolored hot water, water pooling around the base of the tank, inconsistent heating, or a unit that’s simply past its expected lifespan. If you’re spending money on recurring repairs for an older unit, replacement is usually the smarter investment. Garden City Plumbing & Heating in Missoula can assess your system and give you an honest recommendation.
Should I replace my water heater with a tankless system?
Tankless water heaters provide on-demand hot water, use less energy than traditional tank units, and typically last 15–20 years — significantly longer than a standard tank. However, they cost more upfront and may require infrastructure upgrades like updated gas lines or electrical panels. Whether a tankless system is right for your Missoula home depends on your household size, usage patterns, and existing setup. Garden City Plumbing & Heating will walk you through a real cost-over-time comparison before you decide.
How long does water heater installation take?
A standard tank water heater replacement typically takes 2–3 hours for a Garden City Plumbing & Heating technician in Missoula. Tankless installations or jobs that require infrastructure changes — new venting, updated gas lines, or electrical work — may take longer. We’ll give you a realistic time estimate before installation day so you can plan accordingly.
What size water heater do I need for my home?
The right water heater size depends on the number of people in your household, your peak hot water demand, and the type of system you’re installing. As a general guide, a 40-gallon tank typically suits 2–3 people, while a 50–80 gallon unit is better for larger households. Tankless sizing is measured in flow rate rather than gallons. Garden City Plumbing & Heating helps Missoula homeowners right-size their water heater during an on-site assessment — getting this wrong costs you in energy and comfort for years.
Do you install gas and electric water heaters in Missoula?
Yes. Garden City Plumbing & Heating installs both gas and electric water heaters throughout Missoula and Western Montana, including tank, tankless, and heat pump models. If you’re considering switching fuel sources — for example, converting from gas to electric or installing a heat pump water heater — we assess your home’s infrastructure and handle everything from the unit to the connections.
What brands of water heaters do you install?
Garden City Plumbing & Heating works with premier equipment manufacturers and installs a range of leading water heater brands. As a locally owned Missoula company with decades of experience, we focus on units that are well-suited to Western Montana homes — built to handle cold inlet temperatures, local water conditions, and the demands of year-round use. Call (406) 481-3548 to discuss which brands and models we currently carry and recommend.
How much does water heater installation cost in Missoula, MT?
Water heater installation costs in Missoula depend on several factors: the type of system (tank vs. tankless vs. heat pump), the size and capacity of the unit, your existing infrastructure, fuel type, and the complexity of the install. A basic like-for-like tank replacement involves different costs than a full tankless upgrade that requires new venting or electrical work. Garden City Plumbing & Heating provides a clear, itemized quote before any work begins — so you know exactly what you’re approving.
Do you haul away the old water heater?
Yes. Garden City Plumbing & Heating handles removal and disposal of your old water heater as part of the installation process. You won’t be left with a tank sitting in your garage. We take care of it cleanly and correctly so you don’t have to.
