Water heater repair, diagnosed by specialists
Hot-water problems are rarely one part. Burner or element, thermostat, thermocouple, dip tube, anode, gas valve, TPR valve — each fails differently. Our technicians walk that chain in a single visit and hand you the honest fix.
Most repair calls in the area fall into a handful of buckets: the burner or heating elements are worn, the thermostat is out of calibration, the pilot assembly has quit, sediment has caked across the tank floor, or the unit is simply at the end of its service life. The right call depends on the age of the tank, the failure mode, and whether the repair genuinely extends the life of the heater or only postpones a replacement by six months.
Our trucks show up fully stocked. Elements, thermostats, thermocouples, gas control valves, TPR valves, dip tubes, sacrificial anodes, flex connectors, and expansion tanks are all on board — so repairable failures are typically fixed the same visit, without a second service fee for a return trip.
What we repair, every week
- Heating element replacement (electric)
- Upper & lower thermostat swap
- Thermocouple / flame sensor
- Gas control valve replacement
- Pilot assembly & igniter
- TPR (safety) valve replacement
- Sediment flush & tank clean-out
- Anode rod replacement
- Dip tube replacement
- Expansion tank install
- Leaking supply / flex connector
- Tankless error-code diagnosis
- Tankless heat-exchanger descaling
- Recirculation pump repair
When repair is the right answer
Repair almost always wins when the heater is under eight years old, the tank itself is dry and intact, and the failure is a single discrete component. A twelve-year-old tank with a weeping seam in a finished basement off Wadsworth is a different conversation — see the repair vs. replacement guide below.
Pro tip: age the tank before you spend a dollar
Safety warning: TPR valves are not decorative
- Typically quick · Element, thermostat, thermocouple, pilot, TPR, flex
- 1–2 days · Gas valve, tankless control board, recirc pump
- 3–5 days · Warranty-covered heat exchanger swap
Water heater replacement done right
Replacement isn't just swapping a tank. It's sizing correctly for the household, updating the connections to current code, sealing venting properly, and disposing of the old unit — with the City of Arvada permit pulled and a final inspection scheduled.
The most expensive water heater is the one that was sized wrong. A four-bedroom home in Candelas running a 40-gallon tank will chase hot water forever; a two-person townhome near Olde Town with an 80-gallon unit pays every month to heat water it never uses. We size to first-hour demand, not a rule of thumb.
What a proper replacement includes
- Load-based sizing (first-hour rating + peak demand)
- Code-compliant venting: B-vent, direct-vent or power-vent
- New water shut-off, flex connectors, dielectric unions
- Expansion tank sized to house PSI
- New TPR valve and discharge tube to code
- Seismic strapping and drip pan where required
- Combustion air check on gas units
- Altitude derating verified on gas burners
- City of Arvada (or Adams County) permit pulled and inspection scheduled
- Old unit hauled and recycled at no extra charge

Water heater installation — done to code
New construction, whole-house remodels, ADUs, and finished basements. We work directly with homeowners, general contractors, and design-build firms across the west metro.
New construction
Ground-up single-family and townhome projects in Candelas, Leyden Rock, Whisper Creek, and the newer parcels off Indiana Street and 72nd Avenue. We coordinate directly with your GC on rough-in, gas sizing, and inspection scheduling.
Remodels & finished basements
Adding a bathroom to a 1950s brick ranch near Olde Town? Relocating the heater during a kitchen redo in Lake Arbor or Scenic Heights? We handle venting reroutes, gas resizing, and the permit so your remodel passes on the first walk.
ADUs & carriage houses
Detached ADUs are picking up across the older grid around Olde Town, Alta Vista, and Lamar Heights. We spec compact tank, tankless, or heat-pump units sized to the actual load — not the marketing brochure.
Every install includes, without exception
- Load-based sizing (first-hour or GPM)
- Correct venting: B-vent, direct-vent or power-vent
- New shut-off, flex connectors, dielectric unions
- Expansion tank sized to house PSI
- New TPR valve, discharge to code

Installation questions homeowners ask us
Do you pull the permit, or do I?
We pull it, we file it under your address, and we stay on the job until the municipal inspector signs it off. The record follows the home at resale.
How long does a typical install take?
A like-for-like tank replacement is usually a single-visit job. A tankless conversion or a relocation with new venting and gas resizing is typically a longer install and may span a second visit for inspection.
Can you install the unit I already bought?
We can, but we'll walk you through the tradeoffs first — warranty registration, sizing, venting fit, and altitude derating. Most homeowners let us supply the unit so a single warranty covers parts and labor together.
Do you handle gas line or electrical upgrades?
Yes. Tankless conversions and heat-pump installs often need gas resizing, a dedicated circuit or a condensate drain. Those are quoted line-item on the written estimate before install day — no surprises.
One trade, done right. We repair, replace, and install residential water heaters every day of the week for homes from the mid-century ranches around Olde Town and Alta Vista to the newer builds out in Candelas, Leyden Rock, and Five Parks.
No hot water in Arvada? We're on the way.
Failing water heaters don't wait for business hours. Neither do we. Call the emergency line and a licensed technician will respond as quickly as scheduling allows — priority appointments for no-hot-water and active-leak situations from Olde Town out to Candelas and the west-side ridgelines.
- No hot water anywhere in the house
- Water pooling around the tank
- Pilot light won't stay lit
- Loud banging or rumbling from the tank
- Gas smell near the heater
- Pressure relief valve dripping
- Rusty or brown hot water
- Water heater completely burst
Residential water heater work — and only that.
Every technician on our team runs the same equipment every day. That focus is why we diagnose faster, install cleaner, and catch problems a general plumber will miss on the same call.

There is no universally better water heater. There is one that fits your household's hot-water pattern, your gas or electrical service, and the space you have to install it in. Here's how we help homeowners decide.
| Consideration | Tank | Tankless |
|---|---|---|
| Upfront cost (installed) | $1,800 – $3,400 | $4,200 – $7,500 |
| Expected lifespan | 10 – 13 years | 18 – 22 years |
| Space required | Floor: 24″×60″ | Wall: 20″×30″ |
| Simultaneous demand | Limited by tank size | Limited by BTU / GPM |
| Recovery after heavy use | 45 – 60 minutes | Continuous |
| Hard-water maintenance | Annual flush | Annual descale |
| Best for | 1–4 person households, tight budgets | Larger households, remodels, long-term owners |
Tankless installation, repair, and annual descaling
On-demand water heaters reward correct installation and punish neglected maintenance. Here's how we handle each phase of tankless ownership — from a first-time conversion in a new Candelas build to a decade-old unit throwing an error code in a finished basement off Ralston Road.
Tankless installation
Wall mounting, gas-line resizing (often ¾″ upgraded to 1″), stainless or PVC venting, condensate neutralizer, isolation valves, and warranty registration. Sized to peak GPM at Colorado's coldest winter inlet temperature — not a summer-day brochure figure.
Tankless repair
Flame-rod cleaning, ignition and flow-sensor diagnostics, control-board swaps, and error-code triage across Rinnai, Navien, Noritz, Rheem, and Bosch. Most repairs are completed in a single visit with parts on the truck.
Tankless flush & descaling
An annual descale with a food-safe solution strips calcium off the copper heat exchanger, restores GPM to spec, and extends unit life by 30–40%. The moderately hard supply serving most local homes makes this non-negotiable if you want the warranty to hold.
Sizing tankless by GPM, not gallons
Skipping the annual descale voids warranty
Gas, electric, or heat pump — an altitude-specific answer
Xcel Energy natural-gas rates keep gas the efficient default for larger households. But new heat-pump water heaters — combined with Xcel and Colorado Energy Office rebates — are changing the math in tightly sealed homes and conditioned basements.
Gas water heaters
Natural gas heats water quickly and stays inexpensive per BTU compared to grid electricity. The trade-offs are venting and combustion air. At our roughly 5,340 ft base elevation — climbing toward 5,900 ft along the northwest ridgelines by Candelas — gas burners are derated roughly 4% per 1,000 ft above sea level, an install detail your general plumber may skip but we always verify.
- Fast recovery — good for high-demand households
- Lower cost per gallon heated at current CO gas rates
- Requires venting: B-vent, direct-vent or power-vent
- Needs combustion air and proper draft
- Altitude derating verified on every install
Electric & heat pump
Standard electric resistance heaters are simple and reliable. Heat-pump water heaters (HPWH) deliver 3× to 4× the heat per unit of electricity and qualify for federal, Xcel Energy, and Colorado state rebates that can offset most of the upgrade cost. HPWH need conditioned space and a condensate drain — a fit we evaluate during the estimate.
- No combustion air, no venting required
- Heat-pump models: 3–4× the efficiency of resistance
- Rebate-eligible under IRA, Xcel, and CEO programs
- Need proper breaker & wire sizing
- HPWH require condensate drain and airflow
Every failure has a cause. We find it in one visit.
These are the calls we take most often from homes in the area. Read through — if you recognize your symptoms, chances are we carry the parts to address it on the visit.
No hot water at all
Usually a failed thermocouple, gas control valve, or tripped high-limit switch on gas units; a burned-out element or reset breaker on electric.
Puddle around the tank
Could be a dripping TPR valve, corroded drain valve, a loose supply flex — or a leaking tank seam, which is not repairable.
Water not hot enough
Thermostat drift, dip tube failure, sediment buildup, or an undersized tank for the household's real use pattern.
Rusty or discolored hot water
The sacrificial anode has been consumed and the tank is corroding from the inside. Test the anode annually.
Loud banging or rumbling
Almost always mineral scale cooking on the burner surface. A proper flush usually fixes it. On old tanks it can signal a failing bottom.
Pilot won't stay lit
Thermocouple, thermopile, or a dirty pilot orifice — usually a same-visit repair on modern gas units.
Breaker keeps tripping
Failed element with a short to ground, a bad thermostat, or an undersized breaker from a prior install.
Tankless error code
We diagnose ignition, flame-rod, over-temp, and flow-sensor codes across Rinnai, Navien, Rheem, Noritz, and Bosch units.

Text or call with the make, model, and age of your unit and we'll give you an honest read before we roll a truck.
Water heater types and sizes, matched to your household
Choosing between a 40, 50, 75, or 80-gallon tank — or skipping tanks entirely — comes down to first-hour demand, fuel type, and how the space is laid out. A quick primer on the options we install every week.
Storage tank water heaters
The classic 40–80 gallon insulated tank, gas-fired or electric. Lowest upfront cost, simplest install, easiest like-for-like replacement. Best for households whose hot-water use is predictable and clustered (morning showers, evening dishes).
Tankless (on-demand) water heaters
Wall-mounted units that heat water only as it flows. Higher upfront cost, much longer lifespan, unlimited continuous hot water sized to BTU and GPM. Ideal for larger households out in Candelas, West Woods, and Leyden Rock, long-term owners, and remodels reclaiming floor space in older ranches near Olde Town.
Heat pump (hybrid) water heaters
Electric units that pull ambient heat from surrounding air — 3–4× the delivered efficiency of resistance. Best in conditioned basements with a floor drain and Xcel service for rebate eligibility.
Point-of-use & solar-assisted
Small under-sink electric units are a fit for detached ADUs, workshop sinks, and long plumbing runs in older homes around Olde Town and Alta Vista. Solar-thermal preheat is still viable for south-facing roofs with the right orientation.
Which size is right?
| Household | Tank size | Tankless BTU |
|---|---|---|
| 1–2 people, 1 bath | 30–40 gallon | 140,000 BTU |
| 2–3 people, 1.5 bath | 40 gallon | 160,000 BTU |
| 3–4 people, 2 bath | 50 gallon | 180,000 BTU |
| 4–5 people, 2.5 bath | 50–75 gallon | 199,000 BTU |
| 5+ people, 3+ bath | 75–80 gallon or dual tankless | 2× 180,000 BTU |
What water heater work actually costs in Arvada
Real installed prices — not equipment-only, not stripped-down. Numbers include the unit, permit, labor, and all standard code updates. Older homes with extensive venting or gas-line work in the pre-1970s pockets around Olde Town and along Ralston Road land on the higher end.
| Unit type | Installed price | Typical lifespan | Best fit |
|---|---|---|---|
| 40-gal atmospheric gas | $1,850 – $2,600 | 10–12 years | Standard 3-bed household |
| 50-gal atmospheric gas | $2,100 – $2,900 | 10–12 years | 3–4 bed with 2 baths |
| 50-gal power-vent gas | $2,900 – $3,900 | 10–12 years | Utility closet / no chimney |
| 50-gal electric (resistance) | $1,700 – $2,400 | 10–13 years | No gas / townhome |
| 50-gal heat-pump electric | $3,400 – $4,800* | 13–15 years | Rebate-eligible upgrades |
| Tankless gas (interior) | $4,200 – $5,900 | 18–22 years | Space-constrained / high demand |
| Tankless gas (exterior) | $4,600 – $6,400 | 15–20 years | Freeze protection required |
| Tank-to-tankless conversion | $5,800 – $7,500 | 18–22 years | Gas resize + venting + condensate |
* Heat-pump price shown before Inflation Reduction Act, Xcel Energy, and Colorado Energy Office rebates, which frequently cover $1,500–$2,600 of the installed cost.
Water heater replacement cost
A straight like-for-like tank replacement runs $1,850–$2,900 installed for a standard 40 or 50-gallon gas unit — permit, expansion tank, code updates, disposal, and warranty registration included. Power-vent, direct-vent, and tankless conversions add $1,000–$3,500 depending on venting and gas-line work.
Water heater installation cost
A new installation (no existing unit — new construction, ADU, relocated closet) starts around $2,400 and scales with rough-in work. A first-time tankless install with fresh venting and a resized gas line typically lands between $4,600 and $7,500.
We install and service every major residential brand
Our technicians carry manufacturer-authorized training on the brands below. That matters two ways: warranties stay valid, and we know each unit's failure patterns before we open the panel.
Local water is hard on water heaters. A yearly service pays back.
Arvada Water pulls primarily from Ralston Reservoir and supplemental Denver Water supplies. Hardness lands firmly in the moderate range year-round — enough to cake sediment on tank bottoms and scale tankless heat exchangers. An hour a year keeps efficiency up and extends heater life 30–40%.
Annual flush
We drain sediment from the tank bottom, inspect the drain valve, and refill and vent the unit properly.
Anode rod check
The sacrificial anode is the only thing between hard water and your tank steel. We measure remaining rod and swap it before it's fully consumed.
TPR & expansion test
We test the safety valve, verify expansion-tank pressure, and confirm house PSI is inside spec — the leading cause of premature tank failure.
Tankless descaling
Every tankless unit on the local water supply needs an annual descale. We isolate the heater, circulate a food-safe solution, and restore flow to spec.
Combustion check
On gas units we verify draft, flame appearance, gas pressure, and confirm altitude derating is still correct after any Xcel meter changes.
Element & thermostat test
On electric units we meter both elements, verify both thermostats, and confirm no ground faults are developing on aging wiring.
Recommended water heater maintenance schedule
A predictable cadence keeps efficiency up, prevents premature tank failure, and preserves the manufacturer's warranty. Print this and stick it inside the utility-room door.
| Interval | Tank (gas or electric) | Tankless | Heat pump |
|---|---|---|---|
| Every 6 months | Visual leak check, TPR lever test | Check inlet filter screen | Wipe evaporator coil, clear air intake |
| Annually | Full sediment flush, anode inspection, expansion-tank PSI check | Descale heat exchanger, flush isolation valves, clean burner | Full flush, anode inspection, condensate drain flush |
| Every 3–5 years | Anode rod replacement (sooner on softened water) | Replace inlet filter, inspect flame rod & igniter | Anode rod replacement, refrigerant sensor check |
| Every 8–10 years | Plan replacement budget; recheck warranty status | Replace flow sensor / igniter as needed | Compressor & fan performance test |
Water heater lifespan by unit type
How long a water heater lasts depends on fuel, water chemistry, and whether it's been maintained. These are the realistic service lives we see on units across the area — well-maintained on the upper end, neglected on the lower.
- Atmospheric gas tank10–13 years
- Power-vent gas tank10–12 years
- Electric resistance tank10–15 years
- Heat pump (hybrid) water heater13–15 years
- Tankless gas (condensing)18–22 years
- Tankless gas (non-condensing)15–20 years

What Arvada homeowners say
Every review below is from a real, verifiable service call. We pull our public ratings from Google, Nextdoor, and the Better Business Bureau.
Installed a heat pump water heater and walked us through the Xcel rebate paperwork. Total out of pocket was less than what a standard replacement would have been. Very professional crew.
We did a tank-to-tankless conversion. They handled the gas resize, venting through the rim joist, and the City of Arvada permit. Passed inspection first try. Office kept us updated the entire time.
Our 12-year-old heater started weeping around the base on a Sunday. They didn't try to sell us anything on the phone — walked us through shutting off the water and had a new 50 gallon installed Monday morning.
Called at 6 a.m. with no hot water. Tech was on-site by 8:15, diagnosed a bad gas control valve, had one on the truck, and I was showering by lunch. Priced exactly what was quoted.
Third company we called for a tankless error code. First two wanted to replace the whole unit. Their tech diagnosed the flame rod in fifteen minutes and cleaned it. $220 instead of $6,000.
Annual maintenance visit. They flushed the tank, replaced the anode rod, and showed me the expansion tank was shot. Fixed it on the spot. Not pushy about anything, just useful.
Serving neighborhoods across Arvada
From the mid-century ranches around Olde Town and Alta Vista to the newer subdivisions out in Candelas, Leyden Rock, and West Woods, we cover every ZIP code — 80002, 80003, 80004, 80005, and 80007 — and most surrounding communities without an added trip charge.
Local details that matter
- Elevation: Arvada sits between roughly 5,340 and 5,900 ft, climbing gently from the older grid near Olde Town toward the newer builds along the northwest ridgelines around Candelas and Leyden Rock. Gas burners are derated on every install we do.
- Water: Arvada Water serves the city directly, pulling from Ralston Reservoir and supplemental Denver Water supplies. Hardness sits in the moderate range year-round — plan on annual tank flushing and tankless descaling.
- Permits: The City of Arvada Building Inspection Division issues permits for most addresses; the small slice of Arvada inside Adams County goes through the county building department. We pull it every time.
- Utilities: Xcel Energy for natural gas and electric service across the city. Rebates on efficient equipment run through Xcel and the Colorado Energy Office.
Arvada permits, code requirements, and Colorado rebates
A code-legal installation protects your homeowner's insurance, your warranty, and the resale value of the house. It also unlocks utility and federal rebates that can knock thousands off a heat-pump or high-efficiency install.
Arvada water heater permits
The City of Arvada Building Inspection Division requires a mechanical or plumbing permit for water heater replacement inside city limits. Addresses on the Adams County side of the city go through the county building department. We pull the permit under our license, schedule the inspection, and hand you the closed-out paperwork.
Code requirements
- • Expansion tank on any closed system with a PRV or backflow
- • Sediment trap and appliance shutoff on the gas line
- • Full-port cold-side shutoff within reach of the unit
- • TPR discharge run to within 6″ of the floor or a drain
- • Seismic strapping in garages and living spaces
- • 18″ ignition height on gas units in garages (unless FVIR)
- • Drip pan piped to drain on any unit above finished space
