❄️ Maximise your heat pump performance this winter!

Simple steps can make a big difference: 🌡️ Schedule heating wisely 💧 Reduce peak demand 🌬️ Maintain good ventilation 🔧 Keep up with servicing 💰 Use off-peak tariffs

Stay comfortable and use energy smarter this winter!

This is probably the single most repeated myth in Manitoba HVAC conversations, and it's outdated by about a decade.

Older heat pump technology genuinely did struggle below freezing — that part of the myth used to be true. But cold-climate heat pumps (the ones sold and installed today) are a different category of equipment entirely. They're engineered specifically to keep extracting heat from outside air well into negative temperatures, and manufacturers test and rate them for exactly the kind of winters Winnipeg gets.

Where the myth still has a grain of truth: at the very coldest stretches of a Manitoba winter, even a good cold-climate heat pump's output can dip. That's why most homeowners here don't go 100% heat pump — they run a hybrid setup, heat pump as the primary system, furnace kicks in as backup only on the harshest days. You get the efficiency and rebate eligibility most of the year, with a safety net for the -30°C weeks.

So the real answer isn't "don't get a heat pump in Winnipeg" — it's "get the right setup for Winnipeg," which for most homes means a hybrid system, not an either/or choice.

When people invest in a modern underfloor heating system or a heat pump, they usually focus on the expensive equipment.

However, one relatively small component often determines whether the entire system will operate efficiently for decades:

The air and dirt separator.

Why Is It So Important?

Every hydronic heating system gradually accumulates contaminants.

These include:

Magnetite

Sludge

Corrosion particles

Air microbubbles

If these contaminants continue circulating through the installation, they can:

✔ reduce system efficiency

✔ clog plate heat exchangers

✔ damage ECM circulation pumps

✔ increase energy consumption

✔ shorten the lifespan of expensive heating equipment

Clean Water Means Higher Efficiency

Modern heat pumps rely on stable hydraulic flow.

Even small pressure losses or contamination inside the installation can reduce performance.

A properly selected separator continuously removes:

dirt particles

magnetic sludge

dissolved air

This keeps the heating system operating at peak efficiency.

Correct Installation Matters

The installation location is just as important as the separator itself.

Generally:

• Air separators should be installed on the hot supply line.

• Dirt separators should be installed on the return line before the heat source.

Correct positioning maximizes protection for the entire system.

More Than Just Theory

I recently published a comprehensive technical guide covering:

• separator selection

• installation diagrams

• pressure drop calculations

• hydraulic recommendations

• engineering best practices

The article also includes several interactive engineering tools that simplify hydraulic calculations and equipment selection.

A properly designed heating system is not only about choosing the right heat source.
