Ready to Upgrade to Tankless Hot Water?
Let’s assess your home’s hot water demand and show you how much you’ll save. We’ll evaluate your gas line, venting options, and flow requirements, then present tankless models with upfront and long-term costs.
Why Scottsbluff Homeowners Choose Tankless Installation
Unlimited Hot Water On Demand—No Cold Showers, No Waiting
A tankless unit heats water instantaneously as it flows through the system, so you never run out mid-shower or during heavy use. Multiple showers running simultaneously, laundry and dishwashing at the same time—a properly sized tankless system handles it all. This is fundamentally different from tank systems, which deplete their reservoir during peak usage and then slowly reheat. For families with high hot water demand, tankless eliminates the frustration of waiting for reheating or the guilt of telling kids to take quick showers.
30–40% Lower Water Heating Costs Long-Term
Because tankless units only heat water when you demand it, you eliminate the standby heat loss that tanks suffer. A 40-gallon tank heats its entire volume every few hours, whether you use it or not—waste. Panhandle winters make this loss especially expensive. Studies show tankless systems deliver substantial annual savings for the average family; over a 15–20-year lifespan, those savings often exceed the upfront cost difference. Propane tankless units are even more efficient in our region where propane costs less than electricity.
Factory-Trained Installation for Complex Systems
Tankless installation is significantly more involved than tank replacement. Sizing requires precise calculation of simultaneous flow demand, gas line upsizing for the high BTU requirements, Category III stainless steel venting, and control module programming so temperature remains consistent. Many DIY attempts and budget installers leave customers with inconsistent temperature, inadequate flow, or unreliable operation. Our technicians are factory-certified on Rinnai and other leading brands, ensuring your unit is commissioned to manufacturer specifications so you get the performance and warranty protection the system is engineered to deliver.
Space Savings and Modern Efficiency
Tankless units are compact—about the size of a large briefcase mounted on a wall—freeing up floor space in basements, utility rooms, and closets. Combined with their 15–20-year lifespan (vs. 8–12 years for tanks), a tankless system is a long-term investment in efficiency, reliability, and convenience. Modern units include remote controls, smartphone apps for temperature adjustment, and smart features that integrate with your home automation.
Mitsubishi Diamond Dealer & Factory-Backed Expertise
Our partnership with leading manufacturers means ongoing technical support, access to genuine parts, and extended warranty options that reward professional installation. When you buy a tankless unit from us, you’re getting not just a product but also our accountability for proper commissioning and responsive support if issues arise.
Transparent Sizing, Transparent Costs, Flexible Financing
We assess your household’s simultaneous hot water demand, test your existing gas line capacity, evaluate venting options, and calculate the right BTU capacity before recommending equipment. This assessment prevents undersizing (cold showers during peak use) and oversizing (wasted money). We provide detailed written estimates so you know exactly what you’re paying for. Synchrony and Service Finance financing spreads costs over 12–60 months with no money down for qualified homeowners.
Signs It’s Time to Upgrade to a Tankless Water Heater
You Frequently Run Out of Hot Water
If your household regularly exhausts the tank’s supply during morning showers, evening laundry, or back-to-back baths, your current system can’t keep up with demand. A properly sized tankless unit eliminates this problem entirely—it heats water on demand, so the supply is effectively unlimited as long as your gas supply and flow rate are adequate. This is the most common reason homeowners switch to tankless.
Your Energy Bills Are Higher Than Expected
Traditional tank water heaters run heating cycles every few hours to maintain temperature—even at 2 a.m. when no one is using hot water. This standby heat loss adds up significantly over a year, especially in cold panhandle winters where the tank loses heat faster. If your utility bills seem high relative to your usage, your water heater may be a major contributor. Tankless units eliminate standby loss entirely.
Your Tank Water Heater Is 8–12 Years Old
Tank water heaters typically last 8–12 years. As they age, efficiency drops, sediment builds up, and the risk of failure increases. Rather than waiting for a tank failure (which often means an emergency replacement with whatever is available), proactively upgrading to tankless gives you time to choose the right system, plan the installation, and potentially qualify for rebates or financing.
You’re Remodeling or Adding a Bathroom
Adding a bathroom, finishing a basement, or building an addition increases your household’s hot water demand. If your existing tank is already near capacity, adding more demand will push it over the edge. A tankless upgrade during a remodel is ideal timing—venting and gas line work can be coordinated with other construction, and you can right-size the system for your expanded home.
You Need More Space in Your Utility Room
A 40–80-gallon tank takes up significant floor space. Tankless units mount on the wall and are roughly the size of a large briefcase. If you’re converting a utility room, adding storage, or simply want to reclaim space, switching to tankless frees up that footprint permanently.
You Want to Reduce Your Environmental Footprint
Tankless water heaters use 30–40% less energy than traditional tanks, which directly reduces your home’s carbon footprint. If you’re making other energy-efficiency upgrades—insulation, windows, HVAC—adding a tankless water heater is a natural complement that compounds your overall efficiency gains.
Our Tankless Water Heater Installation Process
A tankless unit only works well if it’s sized correctly for your home’s peak hot water demand. We don’t estimate based on guesswork—we calculate precisely. Our technician visits your home and asks detailed questions: How many people live here? How many bathrooms? Do family members shower simultaneously? Do you run laundry and dishwasher during peak morning/evening times? What’s your typical hot water usage pattern?
- Calculate peak simultaneous hot water demand for your household size and usage patterns
- Measure inlet water temperature in summer and winter to determine heating load
- Inspect existing gas line capacity and identify any upsizing needed for code compliance
- Evaluate available venting routes (roof, exterior wall, chimney reuse) and associated costs
- Test water quality and hardness to recommend descaling maintenance intervals
- Review equipment options: fuel type (natural gas, propane, electric), brand, BTU capacity, and long-term operating costs
- Discuss smart thermostat integration and remote control features
- Explain the difference between condensing and non-condensing models, warranty options, and energy efficiency ratings
Tankless units are high-BTU appliances—they demand significantly more fuel than traditional tank water heaters. Existing gas lines sized for a tank system are often too small, causing inadequate pressure and undersized performance. We inspect your gas line from the meter and determine if upsizing is necessary. In many homes, a half-inch line serving a tank becomes a three-quarter-inch line for a tankless unit.
- Upsizing gas line from meter to unit if current capacity is insufficient
- Ordering Category III stainless steel venting materials (not standard B-vent)
- Planning venting route: roof penetration, exterior wall direct vent, or chimney conversion
- Ensuring proper pitch and termination to prevent water intrusion, freezing, or animal nesting
- Verifying code compliance for vent termination distance from windows and air intakes
- Identifying and planning any structural modifications (penetrating roof, exterior walls, interior framing)
- Calculating installation timeline based on venting complexity (simple exterior wall vent vs. complex roof/interior work)
Once you’ve approved the plan and purchased your tankless unit, we schedule the installation. If you’re replacing an existing tank water heater, we carefully drain the old tank, disconnect gas/water lines, and haul away the old unit responsibly. If this is a new installation, we prepare the designated wall or mounting location.
- Mount the tankless unit securely on wall or pedestal, accounting for weight and vibration isolation
- Connect natural gas or propane supply line with proper gauge copper tubing and shut-off valve
- Install cold water inlet line with isolation valve and sediment filter (recommended for hard water areas)
- Connect hot water outlet line with isolation valve and proper slope for drainage
- Install Category III stainless steel venting with proper pitch, supports, and termination
- Run electrical power line (120-volt, typically) and ground per code
- Connect vent termination per code: minimum distance from windows, doors, and outdoor air intakes; proper cap to prevent rain and animal intrusion
- Pressure-test all water connections for leaks and electrical connections for proper voltage
- Install or configure any bypass valves, check valves, or expansion tanks required by code or manufacturer
After physical installation, we commission your tankless unit—this is where expertise matters. We fill the system slowly to eliminate air pockets (which cause temperature fluctuations and noise), bleed any air from lines, and perform initial startup under controlled conditions.
- Fill system slowly to purge air pockets and eliminate temperature spikes
- Program the control module for your preferred output temperature and comfort settings
- Test hot water delivery at multiple fixture combinations: single shower, shower + sink, dishwasher + shower, etc.
- Verify consistent temperature during simultaneous demands without “cold water sandwich”
- Configure smart thermostat and smartphone app (if equipped) and test remote adjustment
- Run diagnostic safety checks: gas leak detection, combustion analysis, pressure/temperature sensor verification
- Test electrical grounding, safety breaker function, and emergency shutdown
- Verify venting integrity and confirm proper draft
- Document all settings and commissioning results for your records and warranty
Your tankless system is only as good as your understanding of how to operate it safely and maintain it properly. We walk you through every feature: the remote control interface, smartphone app functions, temperature adjustment, emergency shut-off, maintenance schedules, and what to expect seasonally.
- Demonstrate the unit’s control panel and remote control operation
- Explain smartphone app features and how to adjust temperature from your phone
- Show you how to interpret any status lights or error codes
- Discuss water temperature seasonal adjustments (hotter water in winter may feel excessive; you can dial it down)
- Explain descaling requirements if your water is hard (annual descaling extends unit lifespan significantly)
- Review filter replacement schedule and show you how to access/replace the cold water inlet filter
- Discuss what emergency shut-off looks like and when to use it
- Provide maintenance reminders and explain the benefits of annual professional inspections
- Leave you with detailed commissioning documentation, warranty information, and Gering Valley service contact info
- Review what’s covered under equipment warranty, our labor warranty, and extended warranty options
- Discuss membership in our Superhero Maintenance Club for annual descaling and service discounts

Get a Rinnai EstimateAO Smith Tankless Installation
AO Smith offers a strong lineup of natural gas and propane tankless units with excellent efficiency ratings. We install AO Smith systems with the same precision commissioning process: demand calculation, gas line evaluation, venting planning, and full system testing. AO Smith’s warranty requires professional installation—we ensure your unit qualifies.
Get an AO Smith EstimateGas Line Upsizing for Tankless
Most homes need gas line upsizing when switching to tankless. Tankless units demand significantly more BTU than tank systems. We inspect your existing line from the meter, calculate required capacity, and upsize as needed using proper copper tubing and fittings per code. This work is included in our installation estimate so there are no surprises.
Gas Line AssessmentCategory III Venting Installation
Tankless units require Category III stainless steel venting—not the standard B-vent used for tank systems. We plan and install venting routes through exterior walls, roofs, or converted chimneys, ensuring proper pitch, support, and termination per local codes. Correct venting prevents back-pressure, corrosion, and carbon monoxide issues.
Venting ConsultationCondensing Tankless Unit Installation
Condensing tankless units achieve 95%+ efficiency by cooling exhaust before it exits, allowing PVC venting instead of stainless steel. They cost more upfront but deliver greater long-term savings. We install condensing models from Rinnai, AO Smith, and other brands, and help you calculate whether the efficiency premium pays back within your expected ownership period.
Condensing Unit InfoPropane Tankless Installation
Many panhandle homes use propane rather than natural gas. Propane tankless units are highly efficient and well-suited to our region. We install propane systems with proper regulator sizing, line pressure verification, and commissioning for propane BTU values (different from natural gas). We also coordinate with your propane supplier if tank sizing needs to be evaluated.
Propane System EstimateTank-to-Tankless Conversion
Converting from a traditional tank to tankless involves more than swapping equipment. We drain and remove your old tank, assess gas line and venting requirements, install the new tankless unit with proper connections, and commission the system. We haul away the old tank responsibly. This is our most common installation type and we’ve refined the process for efficiency and minimal disruption.
Conversion EstimateWhole-Home Tankless System Design
Larger homes with high simultaneous demand may benefit from multiple tankless units or a high-capacity commercial-grade unit. We assess your home’s total hot water demand, evaluate whether a single large unit or multiple units is more cost-effective, and design a system that meets your needs without oversizing. Proper whole-home design prevents the most common tankless complaint: inadequate flow during peak use.
