Campbellford Is Four Degrees Colder Than Toronto — Undersizing Here Isn’t a Paperwork Problem
Campbellford sits well inland of Lake Ontario’s moderating influence, and its SB-1 design temperature shows it: -22°C, the same as Peterborough. Around Trent Hills, Havelock and the Kawartha lakes, a GTA-calibrated calculation doesn’t just fail at the permit office — it produces a house that can’t hold temperature in a February cold snap.
GTA-Calibrated Calculation
Four degrees of design-day difference is real capacity. A system sized for -18°C runs flat-out and loses ground on the coldest nights of the year — exactly when failure matters most.
Cold house in FebruaryPropane Sized by Guesswork
Much of Trent Hills runs on propane, and propane punishes oversizing twice — capital cost and short-cycling. An oversized rural install wastes money every single month.
Oversized & expensiveCSA F280 at -22°C
Room-by-room load at the real inland design temperature, with heat pumps sized from certified output at -22°C and backup heat set from the actual balance point.
Accepted first submissionExactly What Trent Hills’ Building Department Expects to See
New builds, cottage-to-four-season conversions, propane system design, and cold-climate heat pumps with rebate documentation — the complete OBC 2024 package for every project type.
Room-by-Room CSA F280 Heat Loss & Gain
Every room calculated separately at Campbellford’s -22°C design temperature — walls, windows, ceiling, floor, infiltration.
Equipment Sizing Sheet
Right-sized furnace, heat pump, boiler, or AC matched to the calculated load — not a square-footage guess.
Duct or Hydronic Layout Drawings
Fully dimensioned supply and return layout with airflow for every room per HRAI standards.
MVDS & Ventilation Design
The Mechanical Ventilation Design Summary — mandatory on every Ontario new-home permit since January 1, 2025 — plus HRV/ERV selection.
Schedule 1 & BCIN Stamp on Every Page
Signed designer declaration and BCIN stamp throughout — exactly what the Municipality of Trent Hills requires before issuing your permit.
Cold-climate heat pumps absolutely work at -22°C — but only when sized from certified output at that temperature, with backup heat established from the real balance point. All of it starts from this number.
Serving Trent Hills, the Kawarthas & Rural Northumberland
Waterfront cottages converting to four-season homes need their envelope upgrades reflected in the load, not a square-footage guess. Rural propane systems need honest sizing to avoid paying twice for oversized equipment. Both start with a correct F280 at -22°C.
Trent Hills accepts externally prepared BCIN-stamped design packages; we format for direct submission and answer plans-examiner questions at no charge. Same package available at Peterborough’s -22°C for City of Peterborough permits.
Only Need the Heat Loss Report?
The full HVAC design package is $695 flat. If your project only requires the certified CSA F280 heat loss calculation at -22°C, that’s $395 — same 48-hour delivery.

The questions Campbellford homeowners and builders ask most — answered in plain language.
Do cold-climate heat pumps actually work at -22°C?
Yes — when sized correctly. We verify the CCASHP’s certified output at -22°C against your calculated load and establish backup heat from the real balance point. Nominal BTU ratings on the box mean nothing at design temperature. Heat pump sizing guide →
Can you design for a cottage-to-four-season conversion?
Yes — it’s a Trent Hills specialty. The conversion permit needs a heat loss calculation reflecting the upgraded envelope, and often a ventilation design too, since sealed-up cottages need mechanical fresh air.
Do you cover Peterborough?
Yes — same package at Peterborough’s -22°C SB-1 design temperature, formatted for the City of Peterborough’s permit process. Havelock, Marmora, Stirling and rural Northumberland too.
How does propane change the design?
Propane costs more per BTU than natural gas, so oversizing hurts twice — purchase price and running cost. A correct F280 load routinely supports a smaller furnace or a hybrid heat-pump-plus-propane setup that cuts fuel use dramatically.
