Decision
Best answer
Why it matters
Ask before booking
Good fit
You want one company that handles plumbing plus HVAC/electrical coordination.
Tankless jobs may involve gas line, venting, condensate drain, electrical outlet, water piping, and permit/code details.
“Will one Great Dane team handle plumbing, electrical, gas, venting, and permit coordination?”
Good fit
You are in Macomb/Oakland/Metro Detroit and want an in-home estimate.
Great Dane’s own pages focus on Metro Detroit, Macomb County, Oakland County, Clinton Township, Farmington Hills, and nearby cities.
“Is my ZIP code inside your active tankless water-heater service area?”
Good fit
You want to compare traditional tank, tankless, and hybrid electric options.
Great Dane’s water-heater pages discuss storage-tank, tankless, and hybrid electric water heaters, not only one type.
“Please quote tankless and the best non-tankless alternative so I can compare payback.”
Compare estimates
Your existing gas line, vent path, or utility room is difficult.
ENERGY STAR says installers should confirm GPM size, natural-gas line sufficiency, electricity near the heater, and venting.
“Is the quote all-in, or can gas/vent/electrical upgrades increase the price?”
Compare estimates
You are mainly chasing lowest upfront cost.
Tankless usually costs more upfront than a standard tank, even though it can save energy and space over time.
“What is the installed price difference between standard tank and tankless after coupons/rebates?”
Do more homework
You need exact rebate/tax-credit confirmation.
Utility rebates change, funds can run out, and federal energy credits for property placed after Dec. 31, 2025 are not available unless rules change.
“Which rebate applies to my utility account, model number, UEF, install date, and contractor participation?”

Bottom line: Great Dane is worth evaluating if you are in Metro Detroit and want a licensed, multi-trade contractor to size, install, and service a tankless unit. Do not book based only on the coupon. Ask for the model, UEF, GPM, venting plan, gas/electrical work, permit handling, maintenance requirements, and rebate eligibility in writing.

Is a Tankless Water Heater Right for Your House?

Good fit

You want continuous hot water, more floor space, and lower standby energy loss.

Needs sizing

Tankless output is rated by gallons per minute, not tank gallons.

Needs site check

Gas line, vent route, drain, electrical outlet, and water hardness can change cost.

Not always best

A standard tank or heat pump water heater may be better if upfront budget is the main concern.

Household situation
Tankless answer
What to ask Great Dane
Two showers plus dishwasher or laundry may run together
Tankless can work, but GPM capacity matters.
“What GPM do I need for simultaneous fixtures in Michigan winter groundwater?”
Old 40- or 50-gallon gas tank failed
Tankless may be an upgrade, but installation is not always a simple swap.
“Does my current gas line and venting support tankless without upgrades?”
Electric tank water heater replacement
Compare heat pump water heater before choosing electric tankless.
“Would a heat pump water heater save more than electric tankless for my home?”
Small utility room / finished basement
Tankless wall-mount design can save space.
“Where will the unit, vent, condensate drain, and service access go?”
Hard water / scale issues
Maintenance becomes more important.
“How often should this tankless unit be flushed in my area, and what does maintenance cost?”
Lowest upfront cost matters
Standard tank usually wins upfront.
“Give me tank and tankless quotes side by side after coupon, rebates, permit, and warranty.”

What a Great Dane Tankless Quote Should Include

Exact model, fuel type and capacity

Ask for brand, model number, fuel type, UEF efficiency, BTU input, and gallons-per-minute rating. A vague “tankless install” quote is not enough.

Fixture demand and GPM sizing

ENERGY STAR buying guidance uses GPM demand. Ask the estimator to size for realistic simultaneous use, such as shower + dishwasher + laundry.

Gas, electric, vent and drain scope

Tankless jobs can require gas-pipe sizing, electrical outlet, sealed venting, condensate drain, neutralizer, water piping changes, and old-tank disposal.

Permit and code handling

Ask who pulls the permit, whether inspection is included, and whether the estimate includes any required code corrections.

Maintenance and warranty terms

Ask for labor warranty, manufacturer parts warranty, heat-exchanger warranty, flushing schedule, water-softener recommendation, and service-plan cost.

Copy-paste estimate request: “I’m comparing tankless water-heater options for [city/ZIP]. Please quote installed price with model number, UEF, GPM, warranty, permit, venting, gas/electrical changes, condensate drain, old-tank removal, rebate eligibility, and maintenance requirements.”

✅

Positive signals

  • Metro Detroit service history since 1999.
  • Plumbing, electrical, and HVAC under one company.
  • Published contractor license numbers.
  • Official request-service and contact forms.
  • Water-heater page covers tank, tankless, and hybrid electric options.
🧾

Things to verify

  • Current price after coupon and financing.
  • Whether your city requires permit/inspection.
  • Exact model and warranty.
  • Utility rebate participation.
  • Whether gas/electric upgrades are included.
🚩

Red flags in any quote

  • No model number.
  • No GPM sizing explanation.
  • No written permit responsibility.
  • No venting or gas-line scope.
  • No maintenance explanation.

Best evaluation method: ask Great Dane for a complete tankless quote, then compare it against one other licensed plumber using the same model class, capacity, venting scope, rebate assumption, warranty, and permit responsibility. A lower quote is not better if it leaves out gas, vent, drain, or inspection work.

Coupons, Utility Rebates and Tax Credit Reality Check

Great Dane coupon

Great Dane’s plumbing specials page lists $500 off a tankless water heater, expiring July 31, 2026. Restrictions apply, cannot be combined, and can be used once per household.

DTE customers

DTE lists water-heater instant discounts for eligible residential natural gas customers replacing gas water heaters, including ENERGY STAR tankless water heaters meeting program requirements.

Consumers Energy customers

Consumers Energy lists instant rebate paths for gas tankless water heaters for natural gas customers when eligible equipment is installed through participating contractor channels.

Money-saving item
What to verify
Ask this before signing
Great Dane $500 tankless offer
Expiration date, household limit, restrictions, combination rules.
“Is the $500 tankless coupon included in this written quote?”
DTE instant discount
Whether your home is DTE gas, whether the model qualifies, whether Great Dane/installer channel participates, and whether funds remain.
“Will you apply the DTE discount instantly, or do I apply separately?”
Consumers Energy rebate
Whether your home is Consumers Energy gas, whether the model is ENERGY STAR, and whether the contractor route qualifies.
“Is this model eligible under my Consumers Energy account?”
Michigan Home Energy Rebates
Income eligibility, electrification pathway, heat pump water heater eligibility, program availability.
“Should I compare a heat pump water heater before choosing gas tankless?”
Federal energy credit
IRS 2025 instructions state energy efficient home improvement credits end for property placed in service after Dec. 31, 2025.
“Do not include a 2026 federal credit unless you can cite a current official rule.”

Rebate rule: do not assume the installer, coupon, utility rebate, and tax credit all stack. Ask for a final “net cost” line that separates base install price, coupon, utility incentive, permit, optional maintenance plan, financing charges, and any non-guaranteed rebate.

Tankless vs Standard Tank vs Hybrid: Which Quote Should You Ask For?

Option
Best for
Watch out for
Ask Great Dane
Gas tankless water heater
Continuous hot water, space saving, long service life, lower standby loss.
Higher upfront cost, gas line sizing, venting, condensate drain, maintenance flushing.
“What GPM and UEF model fits my peak demand?”
Standard gas tank
Lower upfront replacement cost and simpler swap in many homes.
Can run out of hot water; standby energy loss; tank leak risk as it ages.
“What is the tank quote after the $100 standard-water-heater coupon?”
Hybrid electric / heat pump water heater
Homes replacing electric tanks, utility rebate hunters, energy-efficiency shoppers.
Needs space/air volume, condensate management, longer recovery considerations.
“Would a heat pump water heater beat gas tankless for lifetime cost in my home?”
Point-of-use water heater
Remote sink or fixture far from central heater.
Not a whole-home replacement for most families.
“Is my slow-hot-water problem really a distribution issue instead of heater capacity?”

Most useful ask: request a three-column quote: standard tank, gas tankless, and heat pump water heater. That makes the decision clearer than reading generic “tankless benefits” pages.

Tankless Sizing: Do Not Skip the GPM Conversation

GPM is the key number

Tankless water heaters are rated by gallons per minute, not storage capacity. A bigger household or simultaneous fixtures may need a higher-capacity unit.

Michigan winter matters

Cold incoming groundwater can reduce effective output. Ask for sizing based on local winter temperature rise, not only brochure performance.

Fixture math

Estimate the fixtures that may run together: showers, bathtub, dishwasher, clothes washer, kitchen sink, and bathroom sinks.

Fixture / demand
Why it matters
Quote question
Shower
Often the highest comfort complaint if undersized.
“Can two showers run at once in winter?”
Bathtub
Large tubs need high flow and fast fill rate.
“How long will this unit take to fill my tub?”
Dishwasher + shower
Common evening overlap.
“Will water temperature drop if dishwasher and shower run together?”
Laundry + shower
May require a higher GPM model.
“What simultaneous-use scenario did you size for?”
Long pipe runs
Tankless does not automatically fix long wait time at far faucets.
“Do I need recirculation or point-of-use help?”
Hard water
Scale can reduce performance and shorten life if maintenance is ignored.
“Should I add water treatment or a service plan?”

After Installation: Maintenance Questions That Protect the Investment

Maintenance item
Why it matters
Ask Great Dane
Annual flushing / descaling
Tankless heat exchangers can scale, especially with hard water.
“How often should this model be flushed in my area, and what is your maintenance price?”
Filter cleaning
Inlet filters can restrict flow if neglected.
“Which owner-cleanable filters should I know about?”
Condensate drain / neutralizer
Condensing gas tankless units may need condensate handling.
“Is a condensate neutralizer included and how often is it replaced?”
Combustion and vent check
Safe venting is critical for gas-fired appliances.
“Is vent inspection part of annual tankless service?”
Warranty documentation
Manufacturer warranty may require registration or maintenance proof.
“Will you register the unit and give me warranty documents?”
Service plan
Great Dane offers maintenance programs for home systems.
“Does your MVP/service plan cover tankless flushing and priority plumbing repairs?”
Post-install script: “Before the technician leaves, please show me the shutoff valves, isolation valves, filter location, error-code display, vent path, condensate drain, warranty paperwork, and recommended annual maintenance schedule.”
