How We Assess a Prairie Utility Room Before Recommending Equipment.

We do not guess over the phone or push whole-house water softeners on homes served by naturally soft Shoal Lake water. Our scoping process audits physical mechanical boundaries, combustion margins, and winter Delta-T constraints.

Methodology CAN/CSA-B149
100% Non-Commission Scoping

All audits calculate coincident winter peak loads before specifying burner or tank sizing.

Core Verification Sequence

The 4 Mechanical Scoping Benchmarks

SYS-AUDIT // 01
Fuel Infrastructure

Gas Distribution Capacity Audit

Verification of 1/2" vs 3/4" gas trunk lines, calculating coincident peak load with central furnace to prevent burner starved drops during -35°C polar vortex events.

Branch Sizing Check Pressure Differential Target
Trunk: 3/4" NPT Min. (for 199k BTU) ΔP ≤ 0.5" w.c. Coincident
Furnace Coincident Fire (-35°C)
BTU Margin Audit Regulator Lockup Checked CSA B149.1 Compliant
SYS-AUDIT // 02
Combustion & Exhaust

Venting Geometry & Chimney Integrity

Inspecting clay chimney tile deterioration for atmospheric drafts, or calculating equivalent pipe run feet for dual PVC/polypropylene sidewall penetrations.

Equivalent Length Limit Spillage Risk Status
Max 65 eq. ft (2" PVC) / 150 ft (3") Negative Draft Pass
Tested run: 28 eq. ft / 65 allowable (Safe margin: 57%)
No Orphaned Atmospheric Vents ULC S636 PVC/Polypropylene Frost Hood Clearance
SYS-AUDIT // 03
Electrical Capacity

Panel Availability & Load Calculation

Sizing 240V/30A circuits for Hybrid Electric Heat Pumps or ensuring dedicated 120V GFI outlet proximity for power-vent blowers and tankless control boards.

Service Panel 200A Main
HPWH Breaker 240V / 30A
Control Plug 120V GFI OK
NEC/CEC Subpanel Check Surge Suppressor Spec Ampacity Coincidence
SYS-AUDIT // 04
Hydronic Safety

Potable Baseline & Safety Containment

Verification of municipal backflow devices, ASSE 1017 mixing valves (storing at 60°C for Legionella control while tempering delivery to 49°C), and thermal expansion bladders.

Legionella Disinfection Storage: 60°C (140°F) Tank Core
ASSE 1017 Delivery Temper: 49°C (120°F) Anti-Scald
Expansion Bladder Pre-charge: 65 PSI Match Baseline
Anti-Scald ASSE 1017 Dual Check Backflow Thermal Bladder Calibrated

The Shoal Lake Aqueduct Baseline: Why We Refuse to Upsell Salt Softeners

Winnipeg tap water is drawn through a 137-kilometer gravity-fed aqueduct from Shoal Lake, Ontario. Unlike prairie well water or Saskatchewan deep aquifers, Winnipeg municipal water is naturally soft to moderately soft.

Many commercial contractors run automated sales scripts that prescribe a $3,500 whole-home ion-exchange salt softener on every estimate. We consider this a structural misuse of client capital. Winnipeg water does not produce destructive calcium scale on modern copper or stainless heat exchangers. We advise directing those funds toward certified point-of-use drinking microfiltration and ultra-efficient modulating combustion.

The Clearwater Transparency Rule We verify municipal water source ID on every assessment. If you are on Winnipeg city water, we will actively talk you out of whole-home salt softening.
Hardness Spectrum (GPG) Shoal Lake: 4.7–5.2 GPG
0 GPG (Pure) ▲ Winnipeg (~5.0) 10.5+ GPG (Prairie Wells)
Total Hardness (CaCO3) 80 – 90 mg/L
Scale Accumulation Risk Negligible
Ion-Exchange Salt Need Not Recommended
Optimized Investment Sub-Micron Lead/Taste
Average Capital Preserved $2,800 – $4,200 CAD By declining unnecessary salt softeners
