Pioneering Efficiency: Halton Hills’ Zero Carbon Ambition Realised
When Halton Hills set out to slash arena heating costs and emissions, the town needed more than a tweak here and there. They wanted a leap forward. Enter ammonia-based heat pumps and the magic of a zero carbon refrigerant that turns waste heat into a reliable heating source. The plan? Cut 300,000 kWh from annual electricity bills, dodge gas boilers, and march confidently towards net zero by 2030.
It wasn’t a pie-in-the-sky idea. A feasibility study paved the way. Then the town teamed up with Megawave, whose expertise in expert installation and maintenance services made the switch a no-brainer. Megawave: Eco-Friendly zero carbon refrigerant Air Source Heat Pump Solutions kick-started the process, bringing government grants and flexible finance options into play while ensuring a return on investment faster than most realise.
The Challenge of Arena Emissions
Traditional ice rinks gulp energy like thirsty dragons. Gas boilers for hot water. HFC-based chillers pumping out refrigerants with sky-high global warming potential. The result? Higher bills, rising emissions, and a headache for town councils that want to go green but watch budgets closely.
Key pain points included:
– Outdated equipment nearing end of life.
– A gas-fired boiler that wasted heat.
– High-GWP refrigerant leaks.
– No clear path to net zero.
Megawave saw the opportunity. Swap in a zero carbon refrigerant and reclaim that wasted energy. Simple in theory; powerful in impact.
Halton Hills’ Roadmap to Net Zero
In 2019, Halton Hills declared a climate emergency. Federal rules demanded at least a 50% cut in emissions by 2030 and net zero by 2050. Not fudge figures—real, verifiable cuts. Smaller communities could tap grants from the Federation of Canadian Municipalities (FCM), but only if they showed a solid plan.
The town joined the Roadmap to Net Zero Ice Rink pilot study. Nine arenas got bespoke greenhouse gas (GHG) reduction roadmaps. Three scenarios emerged:
1. Business-as-usual: equipment replaced like-for-like. Minimal savings. Negative NPV.
2. Low carbon without funding: retrofit at end of life. Positive NPV.
3. Low carbon with funding: immediate upgrades plus grants. Highest NPV.
Acton Arena’s numbers told the story. Scenario 3 cost almost the same as doing nothing but delivered massive emissions cuts. The business case was clear—time to act.
Why Ammonia? The Power of a Zero Carbon Refrigerant
Most projects would pick a familiar HFC like R134a. It’s easy to find, quick to install. But it carries a GWP of 1,430 over 100 years. Ammonia? It scores zero. Yes, zero.
Here’s why ammonia shines:
– GWP of 0 means no hidden carbon tax.
– Efficiency roughly double that of R134a.
– Smaller system footprint—less equipment, fewer leak points.
– Annual savings around 300,000 kWh per site.
– Avoidance of six tonnes of CO₂-equivalent every year.
Megawave’s experience shows that switching to a zero carbon refrigerant ammonia system delivers more than green credentials. It cuts run-hours, shrinks maintenance, and accelerates payback. Curious about the numbers? Discover Megawave’s zero carbon refrigerant Advantages
Business Case: Savings, ROI, and Funding
Numbers don’t lie. Megawave worked with the town’s finance team to run a net present value (NPV) model. They compared:
– Baseline (gas boilers + HFC chillers).
– Partial upgrade (low carbon but delayed).
– Full tilt with funding (grants in year one).
Results:
– Negative NPV under business-as-usual.
– Positive NPV if upgrades wait.
– Highest NPV when grants are used up front.
At 2,000 run hours, payback drops below 1.5 years (68% ROI). At 4,000 hours, it shrinks to 10.5 months (109% ROI). Even conservative estimates show a win-win: serious emissions cuts that pay for themselves fast.
Behind the Scenes: Waste Heat Recovery Mechanics
Ammonia refrigeration systems for ice rinks typically reject heat during cooling. Megawave’s trick? Capture that waste heat to warm water and spaces in the arena. No extra boilers. No extra fuel. Just a smart heat pump loop.
How it works:
1. Compressor raises ammonia’s temperature.
2. Condenser coils transfer heat to a secondary loop.
3. Hot water circulates through showers, locker rooms, and radiators.
4. Excess heat feeds back into the refrigeration cycle for free cooling when needed.
This synergy of refrigeration and heating in one package is the essence of a zero carbon refrigerant approach. It’s mature tech with off-the-shelf components—no custom gizmos required. Megawave handles the rest with expert installation and maintenance services, ensuring peak performance year after year.

Lessons for Your Community
Halton Hills proved that small towns can lead on climate action. You don’t need endless budgets—just a clear plan, the right partners, and a commitment to low-carbon tech. If your arena or community building is staring down future equipment replacements, now is the time to pivot.
A feasibility study will give you:
– The when, why, and how of decarbonisation.
– A solid business case with NPV modelling.
– Clarity on available funding streams.
– A roadmap to net zero that actually pays back.
Your community could be next to showcase an ammonia heat pump success story. Why settle for the status quo when a zero carbon refrigerant solution offers lower costs, less emissions, and a fast ROI?
