Gas-to-electric heat conversion
We've been helping plants retire gas-fired heating and run the same process on electric — and we don't hand you a catalog and wave. Feasibility, sizing, panels and commissioning, done together with your team.
The case for electric process heat has changed
A few years ago this conversation was mostly about voluntary goals. Now it's about efficiency, greenhouse-gas reporting and energy bills a plant manager can actually forecast.
Heat where the process is
An electric element converts essentially all the power it draws into heat at the point of use. Combustion systems send a meaningful share up the stack and lose more to standby, distribution piping and flue dampers.
Precision you can't get from a flame
PID controllers firing SCRs modulate power in proportion to demand — holding setpoints within a degree or two, recovering fast after a door opens, and shaving variation that costs you scrap.
Stable, manageable energy cost
Natural gas pricing has whipsawed in recent years. Electric heat is easy to stage, so you can shift load to cheaper off-peak hours — or add thermal storage — instead of riding the fuel market.
No combustion indoors
No burner, no flue, no gas piping to leak-test, no carbon monoxide to monitor. For ovens, dryers and tanks inside the plant, that changes what the space feels like and what your EHS team tracks.
Emissions that fall on their own
You zero out on-site combustion emissions at the converted process, and as the grid keeps getting cleaner, the same system reports a smaller footprint every year — no re-investment required.
Less to maintain
Burners need cleaning, gas valves need testing, flues need inspection. A resistance heater has no moving parts — and the panel tells you it's failing before the process does.
Where electric pulls ahead of gas
Electrification isn't right for every load — high-temperature furnaces especially. But most plant heating sits in the range where electric resistance and modern controls outperform gas.
Tanks, vats and plating solutions
Immersion and circulation heaters hold bath temperatures tightly, eliminate flue-condensate corrosion over the tank, and interlock cleanly against low liquid level.
Ovens, dryers and curing
Tubular and banded elements with multi-zone control give you a flat, repeatable temperature profile — and no combustion byproducts touching the part.
Point-of-use process heat
Seal bars, hopper heaters, die heating, tracing: electric puts the watt exactly where the gas ductwork never could, and only when the machine needs it.
Hybrid gas-plus-electric
Keep the existing boiler or furnace for rare peak demand and add electric trim for normal load. Often the lowest-risk first step — and one we design around your meter, not the other way around.
Under scrutiny? Move the flame off your ledger
GHG reporting keeps traveling down the supply chain, and every therm of gas burned on site belongs to you outright. Here's how the electric side compares — and why we build the numbers into every feasibility review.
The Scope 1 math is simple
Burning natural gas on site is direct — Scope 1 — emissions: reported, assured and owned by your plant, kilojoule by kilojoule. Convert the load and that line goes to zero on day one, replaced by utility emissions factors you can verify and improve.
Your fuel won't get cleaner. Your grid will.
A gas flame emits the same CO₂ per MMBtu in 2035 as it does today. The electricity feeding your converted system keeps getting cleaner as utilities add renewables and retire coal — the same panel, reporting a smaller footprint every year.
No methane you never touched
Natural gas is mostly methane — a greenhouse gas many times more potent than CO₂ over the near term — and some of it leaks unburned through extraction, processing and pipelines. Electric end-use heat takes your footprint out of that supply chain.
A thinner air-permit file
Combustion sources carry stack testing, NOx and CO limits and the recordkeeping behind federal and state boiler rules. Remove the burner and a lot of that apparatus simply stops applying — not legal advice, but fewer smokestacks, fewer obligations.
One team — yours and ours — start to finish
Every conversion we've delivered followed this path. You have a named MAHC engineer on it from the first walkthrough to the last tuning session.

Commissioned & Tuned
1 — We start at your machine, not our catalog
We walk the process, log what the gas system actually delivers, and model the heat-up, hold and loss numbers for your specific load. If electric doesn't beat gas on your numbers, we'll say so.
2 — Sizing the electrical service, together
Working with your electrician and utility, we determine what capacity exists, what a conversion draws, and how to stage contactors or shed zones so the new load fits the service you have — or an upgrade you can justify.
3 — A design you can read
Element selection, watt density, sensors, control strategy and safety interlocks — documented so your maintenance team owns the design, not just the hardware.
4 — Built in our Spartanburg shop
Panels are built, wired and bench-tested before they ship, with the same people who drew the schematic at the bench.
5 — Changeover around your production
We sequence the swap for your maintenance windows, keep gas available as standby where it makes sense, and stay on site for first fire-up.
6 — Tuned until it holds, then supported
Commissioning means the zone holds your setpoint through your real cycle. After that you get our phone number, not a warranty claim form.
The whole electric side, from one shop
As a certified distributor and custom panel builder, we source, engineer and document every component in the converted loop.
Electric Heaters
Band, cartridge, strip, immersion, circulation, duct and tubular elements from Tri-Volt, Thermal Corporation, Heat & Sensor Technology and Watlow — sized for your watt density, not a stock SKU.
See our line cardSensors & Control
Pyromation thermocouples and RTDs matched to the new hardware, with Watlow and Eurotherm controllers running the loops.
How the thermal loop worksPower & Panels
SCR and hybrid power control sized for inrush and duty cycle, wired into a custom panel with the staging, interlocks and high-limit protection a converted system needs.
Custom control panelsLegacy Systems Welcome
Converting in phases — one zone or machine at a time — is a legitimate strategy. We can retrofit incrementally and document each step as-built.
Panel upgrades & retrofitsA conversion is a partnership, not a purchase order
The equipment is the easy half. What makes a gas-to-electric project succeed is someone who will still answer when zone four overshoots on a Tuesday night during the first production run. We've been doing this in the Upstate since around 1990, and the conversions we're proudest of are the ones where the customer's own team could run and maintain the system by week two — because we built it that way together.

Gas-to-electric conversion FAQ
Sometimes per unit of heat, often not — but that's the wrong comparison. Electric systems put more of every dollar into the process (no stack or standby losses), hold temperature tighter so you scrap less, and can be staged to run on cheaper off-peak power. We model your actual load and local rates before anyone signs anything.
That's the goal of how we scope it. Panels are built and bench-tested in our shop while your gas system keeps running, the physical changeover is scheduled into an existing maintenance window, and where risk demands it we keep the gas train online as standby during the first production cycles.
Not usually. Staged contactors, limit controllers and shed strategies let a conversion live inside a capped kilowatt budget, and thermal storage lets you buy heat during off-peak hours for peak-time use. When an upgrade genuinely is needed, we help you build the numbers to justify it with your utility.
Very high-temperature loads — think melting and some forging — and processes where combustion atmosphere is part of the product equation. Electric resistance is strongest below roughly 1,000°F at the part, and especially below 600°F. Our feasibility review tells you honestly whether your load is a good candidate.
No. Many of our conversions are hybrid: electric carries the normal load and existing gas backs up cold starts, winter peaks or product changes. You can retire the fuel system later — or never — once the numbers are proven.
Usually. On-site gas combustion is direct (Scope 1) emissions your plant owns on paper; electric heat moves that load into purchased-electricity (Scope 2) accounting tied to a grid that keeps getting cleaner — and it typically takes the converted equipment out of stack testing and fuel-system reporting. We don't write your permits, but we hand your consultant as-built documentation that makes their job shorter.
