No homeowner wants to wake up to a cold shower. When performance drops or your unit hits the end of its service life, the smartest move is to replace the tankless water heater before it fails. CountBricks combines real-time voice capture, AI cost engines and blueprint takeoffs to turn a stressful upgrade into a predictable, data-driven project.
• Consistent lukewarm water due to scale or worn heat exchangers
• Rising energy bills signaling declining efficiency
• Frequent error codes that require expensive part swaps
• Family size changes demanding higher flow rates
• Desire to switch fuel types—electric to gas or vice versa—for local incentives
An honest evaluation weighs age, parts cost and downtime. CountBricks contractors recommend replacement when:
1. The unit is 10-15 years old—near or past its rated lifespan
2. Repair estimates exceed 40% of a new high-efficiency model
3. Safety issues such as heat exchanger cracks are detected
Traditional estimating takes days. By contrast, CountBricks captures a two-minute smartphone walk-through and instantly produces:
• Line-item labor and material totals
• Current supplier pricing synced daily
• Permit and disposal allowances
• Timeline projections down to crew-hour granularity
You get PDF quotes, interactive dashboards and the option to adjust brand, capacity and venting choices on the fly—no spreadsheet wrestling.
• Standard 6–8 GPM gas unit swap: $2,700 – $3,800
• High output 11 GPM with recirculation loop: $4,200 – $5,600
• Electric whole-house upgrade requiring panel upsizing: $3,000 – $4,500
CountBricks factors every elbow, isolation valve and vent termination so there are no “design-build surprises.”
1. Voice walk-through on your phone creates a digital twin of the utility room
2. AI engine selects compatible models based on gas line size, breaker capacity and flow demand
3. Instant estimate appears—approve with a tap to lock in price
4. CountBricks auto-orders materials and schedules licensed installers
5. On install day, technicians remove the old unit, flush lines, mount the new heater, connect utilities and calibrate
6. Digital QA checklist and site photos populate your CountBricks customer portal
• Gas undersizing—Our blueprint takeoff calculates BTU demand and pipe lengths automatically
• Venting code violations—Field app overlays local code snippets during technician setup
• Hard-to-source parts—Integration with distributor APIs shows stock levels before you approve the quote
• Cost creep—Locked material pricing means the number you sign is the number you pay

Maria and Luis owned a 12-year-old gas tankless unit that struggled to keep up with their growing family. After a two-minute CountBricks voice session, the platform generated three replacement options. They chose a 10 GPM condensing model, attracted by the projected $180 annual savings.
• Estimate to install: 6 days total turnaround
• On-site crew time: 5.5 hours, confirmed via CountBricks time-tracking
• Final cost: $3,450—exactly matching the initial AI estimate
• Post-install satisfaction score: 9.8/10
• Always photograph gas shut-off and vent terminations; CountBricks AI flags clearance issues automatically
• Use isolation valves with service ports to slash future maintenance time
• Tie recirculation pumps to occupancy sensors for maximum energy savings
Traditional bids for Maria and Luis ranged from $3,200 to $4,100 and took a week to arrive. CountBricks not only delivered a firm price on the spot but also synced with supplier inventories, ensuring every component was on the truck the morning of installation.
