Call (416) 828-6976Serving Markham
Markham homeowners increasingly ask us for smart lighting and EV charger installations alongside standard repairs, while local businesses rely on us for ongoing commercial electrical maintenance. Our licensed electricians serve Markham with the same upfront pricing and code-compliant work as everywhere else in the GTA.
In Unionville and Berczy Village, where many homes were built from the 1990s onward, we see more EV charger installations, smart dimmer upgrades, and potlight retrofits than panel replacements. Cornell’s newer new-urbanist homes bring similar requests alongside the occasional builder-grade panel that needs upsizing for a renovation. Around Milliken and Markham’s tech and office corridors, commercial electrical maintenance and lighting retrofits are our most common calls.

More about our work in Markham
Overview
We provide baseboard heater installation for homes and businesses throughout Markham, including Unionville, Milliken, Cornell, Berczy Village, and the rest of Markham.
Electric baseboard heaters offer dependable, whisper-quiet zonal heating for Ontario winters without the expense of running central HVAC ductwork. Electrovoltage provides code-compliant electric baseboard heater installation, electric baseboard heater replacement, and 240V baseboard heater installation across Toronto and the GTA. Whether you are replacing noisy, rusted baseboard heaters with modern high-efficiency convectors or installing new baseboard heater wiring in a finished basement or bedroom addition, our licensed Master Electricians calculate proper heating wattages, run dedicated 120V or 240V circuits from your panel, and handle digital baseboard thermostat installation (including smart thermostats like Mysa and Sinope). For compact spaces like bathrooms, entryways, or workshops, we also specialize in fan-forced wall heater installation. Every installation adheres strictly to Ontario Electrical Safety Code (OESC) Section 62 and includes required Electrical Safety Authority (ESA) permitting.

Why It Matters
Electric baseboard heaters are continuous high-amperage electrical loads governed by strict OESC Rule 8-104 and Section 62 standards. An experienced baseboard heater electrician ensures your circuit never exceeds 80% of breaker capacity (for example, a 15A 240V breaker is capped at 2,880 watts, and a 20A breaker at 3,840 watts). Overloaded circuits, improper wire gauges (such as using 14 AWG where 12 AWG is mandatory), or installing baseboards directly beneath wall convenience receptacles pose severe fire and short-circuit risks. Professional installation guarantees safe clearances, balanced electrical panel loads, and up to 25% lower winter heating costs when paired with electronic or smart line-voltage thermostats.
How Baseboard Heater Installation Works
- 1
Heat loss & wattage calculation
We evaluate room square footage, ceiling height, and insulation levels (typically 10W per sq. ft. in Ontario) to determine precise heater length and heating capacity.
- 2
Dedicated 240V circuit & panel assessment
We assess your electrical panel and run a dedicated 120V or 240V copper home-run circuit with code-compliant Romex cabling (14/2, 12/2, or 10/2) and double-pole breakers.
- 3
Code-compliant baseboard mounting & wiring
We securely mount the unit along perimeter walls away from drapery and electrical outlets, complete all wiring inside grounded junction boxes, and install wall thermostats.
- 4
Testing & ESA inspection sign-off
We verify continuous current draw, check thermal high-limit safety cutoffs, calibrate thermostats, and deliver an official ESA Certificate of Inspection.
What Affects the Cost
Costs in Markham reflect heater design aesthetics (sleek convector panels vs standard baseboards) and whether routing wire from subpanels in detached coach houses requires exterior conduit runs.
Baseboard heater installation cost in Toronto and the GTA depends on whether existing 240V wiring is intact for a direct unit replacement ($250–$450/unit) or a new dedicated home-run circuit must be fished from your electrical panel ($650–$1,200+). Heater wattage, commercial convector styling, and upgrading from basic rotary dials to smart Wi-Fi thermostats also influence pricing. All ESA permits and fees are quoted transparently upfront.
Frequently Asked Questions
- Are modern electric baseboards more energy-efficient than older models in Markham?
- While electric resistance heat is 100% efficient at turning electricity into heat, modern convector units circulate air much faster through natural chimney effect and, when paired with precision digital thermostats, reduce wasted energy by up to 25%.
- Do I need an ESA permit to replace an electric baseboard in Markham?
- Yes. Any permanent high-voltage electrical installation or circuit modification in Ontario requires an Electrical Safety Authority (ESA) permit and certificate, which we handle completely.
- What is involved in electric baseboard heater replacement?
- A standard baseboard heater replacement involves safely disconnecting the old unit, testing the existing circuit wiring for proper gauge and grounding, installing a modern high-efficiency convector heater, and connecting a precision wall thermostat.
- Why does baseboard heater installation require a 240V dedicated circuit?
- Electric baseboard heaters are continuous heavy loads. Operating at 240 volts cuts the amperage draw in half compared to 120 volts, allowing efficient operation without overloading household lighting or receptacle branch circuits.
- Can I replace my built-in baseboard dial with a smart thermostat?
- Yes. We install high-voltage smart thermostats like Mysa or Sinope designed specifically for 120V/240V electric baseboard heaters, providing smartphone control, scheduling, and energy savings.
- What factors determine baseboard heater installation cost?
- Cost depends on whether you need a direct replacement or a brand-new circuit run from the panel, the distance to the panel, heater wattage/length, and thermostat selection. We provide detailed upfront quotes after a free consultation.
- Can baseboard heaters be installed under windows or near curtains?
- Installing beneath windows is ideal for counteracting cold glass drafts. However, code mandates at least 12 inches of clearance from curtains and furniture, and prohibits placement directly below wall electrical outlets.
