Boiler Systems We Install for Heated Driveways in the GTA

The boiler is the engine of a heated driveway — it heats the water that circulates under your slab. These are the three hydronic boiler packages Pisces installs in the GTA, each with proven Canadian availability and support. Pick the tier that fits your home and your budget; we handle the design and the installation.

What the boiler package actually does

A heated driveway needs more than a boiler box on the wall. The mechanical package is the whole heart of the system: the boiler heats the water, circulator pumps push it through the loops under your driveway, a manifold splits it evenly across every circuit, and a smart snow-melting control with slab and air sensors decides when to fire — automatically, while you sleep.

Every package below is a wall-hung condensing boiler (95% efficiency) paired with the same proven supporting cast: circulator pumps, a hydraulic separator and radiant manifold, smart snow-melt controls with sensors, and inhibited propylene glycol. What changes between the three is the boiler itself — its capacity, its quietness and its price.

Three packages, three budgets

All three are commonly installed across Canada. Every price below is an installed planning range for a typical ~1,000 sq ft heated driveway, in CAD — consistent with the boiler + mechanical ranges in our heated driveway guide. Final pricing is always set after a free on-site assessment.

Value pick

Navien NHB-150H

A compact, high-efficiency condensing boiler with one of the widest turndown ratios in its class — it sips fuel in mild weather and ramps up when the storm hits. Built-in control of the boiler pump plus zone pumps keeps the wiring simple.

  • Input (natural gas)10,000–150,000 BTU/h
  • Efficiency95% AFUE
  • Turndown15:1
  • Heat exchangerDual stainless steel

Best for: budget-first projects where the formal heat-load design confirms the capacity fits — our free assessment checks this for you.

$9,000 – $12,500Installed planning range, CAD — boiler + mechanical equipment + controls. Not a quote.
NTI TRX Series II wall-hung condensing boiler

Our balanced pick

NTI TRX199 (Series II)

More heating muscle for full-size driveways, from a Canadian manufacturer (Saint John, NB). Integrated circulator, Wi-Fi and outdoor-sensor input come standard, and it can cascade with up to eight units for larger properties.

  • Input (natural gas)19,700–197,000 BTU/h
  • Efficiency95% AFUE
  • Turndown~10:1
  • Heat exchangerStainless water-tube

Best for: most full-size (~1,000 sq ft) GTA driveways — the sweet spot of capacity, efficiency and price.

  • Input (natural gas)19,900–199,000 BTU/h
  • Efficiency95% AFUE
  • Turndown10:1
  • Heat exchangerStainless Inox-Radial

Best for: premium, no-compromise projects — maximum capacity margin and long-term build quality.

An honest note: product photos above are manufacturer images of each system — photos of real Pisces boiler installs are coming soon. Every price is a planning range, never a fixed quote: your final price is set after a free on-site assessment. Gas-line work, electrical service, permits and inspections, a gas-meter upgrade, excavation, the slab and the driveway finish are quoted separately and transparently.

What a Pisces boiler install includes

Whichever package you choose, the process is the same — one coordinated job, no hand-offs between strangers:

  1. Free on-site assessmentWe visit, measure your driveway and check your gas service, electrical panel and mechanical room space.
  2. Equipment sizingThe boiler and pump sizes are matched to your driveway’s actual heat load — not guessed, not oversized “just in case”.
  3. Gas-line & venting coordinationWe coordinate the gas run and venting route with licensed technicians, so the boiler lands exactly where it should.
  4. Manifold & controls wiringThe manifold, circulators, sensors and smart snow-melting control are installed and wired as one system.
  5. Pressure testing & commissioningThe whole loop is pressure-tested, the controls are calibrated, and we walk you through exactly how it runs before we leave.
The right trades, guaranteed: licensed technicians handle the boiler, gas and electrical hookups — Pisces builds everything around them: excavation, base, the heating layer and the finished driveway surface.

Boiler questions, answered

Which system should I pick?

For most full-size GTA driveways we recommend the balanced NTI package — the best mix of capacity and price. The Navien suits tighter budgets when the design load fits; the Viessmann suits homeowners who want the quietest, most powerful option available. You don’t have to decide alone — we recommend one after the free assessment.

Do these boilers work with the finishes I want?

Yes — the boiler doesn’t care what’s on top. Asphalt, concrete, interlock or natural stone all work; the system is sized for your driveway area and your local winter, not your surface choice.

What does it cost to run each winter?

It depends on driveway size, the winter and your energy rates — typically a few hundred dollars per season for a standard GTA driveway. We walk through realistic running costs for your property during the assessment.

What maintenance does the boiler need?

Like any heating appliance, an annual service keeps it efficient and the warranty in good standing. We hand you a simple maintenance checklist at commissioning.
