Radiant Floor Heating Design in Aurora
Radiant and hydronic floor heating design for Aurora custom homes, renovations and additions — tube layouts, loop lengths, zoning, manifold planning and boiler sizing, all verified against your home’s actual room-by-room heat loss.
Radiant floor heating is the quiet, even, luxurious kind of warmth — no blowing air, no cold corners, warmth underfoot. It’s a natural fit for the kind of custom and high-end homes common in Aurora. But it only delivers that when it’s designed correctly. Done casually, it produces cold spots, warm-and-cold striping you can feel through the floor, a system that responds slowly, or a boiler that never settles in.
ON Point HVAC Design is based in Aurora and provides independent radiant design — we don’t sell tubing or install systems, so the design is built for your home, not for a supplier’s order sheet. You take it to any qualified installer.
Radiant works especially well in Aurora homes — here's why
Aurora’s winter design temperature is colder than Toronto’s −18°C but milder than the deep-cold pockets further north [confirm exact SB-1 figure for Aurora — see notes]. That matters for radiant in a specific, favourable way.
A heated floor can only put out so much heat — there’s a ceiling on watts per square metre, set by floor area, safe surface temperature and what covers the floor. In the coldest climates, a very high heat loss can push a room past that ceiling, forcing supplemental heat. In Aurora’s more moderate climate, that ceiling is reached far less often, which means radiant can more often carry a room’s full heating load on its own — including in well-built custom homes with good envelopes, which describes a lot of Aurora’s newer housing stock.
In other words: Aurora is close to a sweet spot for whole-home radiant. Well-insulated homes here can frequently run radiant as the primary heat source, cleanly, without the compromises a harsher climate imposes. We still verify it room by room — big glazing and high-loss spaces get checked against the floor’s real output — but the odds of a clean, radiant-only design are good here.
What our radiant floor heating design includes
A complete, installer-ready design:
- Room-by-room heat loss at Aurora’s correct design temperature — the foundation everything is sized from
- Tube layout and spacing — tightened along exterior walls and under glazing, so no cold edges or striping
- Loop lengths and counts — kept within limits so no loop’s far end runs cold
- Manifold sizing and placement
- Zoning strategy — matched to how each space is used and to the floor’s thermal mass
- Supply water temperature — designed as low as loads allow, which protects condensing-boiler efficiency
- Boiler and mixing system planning — sized to the real load, with proper protection and mixing
- Floor-covering allowances — the finished floor’s R-value is accounted for so carpet or engineered wood doesn’t strangle output
- Installer-ready drawings and documentation
Almost every radiant failure traces back to one of these being wrong at the design stage — and once tubing is in the slab, you can’t move it. Here’s a plain-language rundown of what goes wrong with radiant and why.

Frequently asked questions
Is radiant floor heating a good choice for an Aurora home? Often an excellent one. Aurora’s climate is cold enough to make radiant’s steady, even warmth genuinely valuable, but moderate enough that a well-insulated home can frequently run radiant as its only heat source. The design confirms this room by room before anything is committed.
Can radiant be my only heat source? Frequently yes, in a well-built Aurora home where the design confirms the floor can meet each room’s full heat loss. Rooms with large glazing or high loss may need supplemental heat — the load calculation identifies which, so it’s a decision, not a surprise.
Do you install radiant systems? No. We provide the design only, independently, and you take it to any qualified installer. We don’t sell tubing or equipment, so nothing in the design is there to pad a sale.
Do you design radiant for basements and additions? Yes — basement slabs and additions are among the most common radiant projects, along with whole-home custom builds.
