Radiant Floor Heating Design — Simcoe County
In-floor and hydronic radiant design for every Simcoe County municipality — CSA F280 load, supply-water temperature, loop and manifold sizing, and boiler or air-to-water heat pump selection, BCIN-stamped for your town.
Radiant floor design in Simcoe County starts from a CSA F280 heat loss calculation at your town design temperature — about -20°C at Innisfil, -21°C at Collingwood and Wasaga Beach, -24°C at Barrie, Oro-Medonte, Midland, Penetanguishene and Tiny, and -25°C at Orillia (all Climate Zone 6). We size supply temperature, loops and manifolds to that load and select the heat source, BCIN-stamped. From $895.
Design temperatures by municipality (Zone 6)
Radiant slabs are unforgiving of an undersized load, so the design must start from your town official January 2.5% value from Supplementary Standard SB-1 — not a neighbouring town or the GTA -18°C. Simcoe County spans a real range:
| Municipality | Design Temp (2.5%) | Zone |
|---|---|---|
| Collingwood, Wasaga Beach, Blue Mountains | -21°C | 6 |
| Innisfil, Bradford, New Tecumseth | -20°C (est.) | 6 |
| Barrie, Oro-Medonte, Springwater | -24°C | 6 |
| Midland, Penetanguishene, Tiny Township | -24°C | 6 |
| Orillia | -25°C | 6 |

What a Simcoe County radiant design includes
Every package starts with a room-by-room CSA F280 heat loss calculation at your town design temperature, then the radiant-specific design: required supply-water temperature, loop length and tube spacing per zone, manifold layout and flow balancing, and heat-source selection — a condensing boiler or an air-to-water heat pump — per CAN/CSA-B214. BCIN-stamped for your municipality, paired with the MVDS and Schedule 1. See the radiant design service.
Heat source: boiler or air-to-water heat pump
Radiant runs at low supply temperatures that suit air-to-water heat pumps, but on the design day output falls to roughly 55-75% of rated capacity depending on your town (less at Orillia -25°C than at Collingwood -21°C). We verify output against the CSA F280 load and specify backup or a boiler where needed. Ground temperatures sit near 8-10°C year-round in Simcoe County, far above the winter air design temperature — which is exactly why the load must be calculated at the correct value. See our cold climate heat pump guide.

Radiant Design in Simcoe County — FAQ
What design temperature is used for radiant design in Simcoe County?
It varies by town within Zone 6: about -20°C at Innisfil, -21°C at Collingwood and Wasaga Beach, -24°C at Barrie, Oro-Medonte, Midland, Penetanguishene and Tiny, and -25°C at Orillia. The radiant load and supply temperature are based on your exact value.
How much does a radiant floor design cost?
A BCIN-stamped radiant design — CSA F280 load, supply temperature, loop and manifold sizing and heat-source selection — starts at $895. A standalone heat loss report starts at $395.
Can an air-to-water heat pump run a radiant floor here?
Yes for well-insulated homes. Radiant low supply temperatures suit heat pumps; on the design day output falls to roughly 55-75% of rated depending on town, so it is verified against the CSA F280 load with backup or a boiler specified where needed.
Does the County of Simcoe issue the permit?
No — each lower-tier municipality runs its own building department. We format the radiant package for your town (Barrie, Collingwood, Wasaga Beach, Midland, Orillia, Oro-Medonte and others).
