How Mitsubishi Electric Heat Pumps Work in Greater Vancouver

A Mitsubishi Electric heat pump heats and cools a Greater Vancouver home without burning any fuel, by moving heat from one place to another using electricity. Understanding how it works makes it easier to see why heat pumps are such an efficient fit for the Lower Mainland's mild, damp climate, and HeatLand can help you put that into practice.

Moving Heat Instead of Making It

Rather than generating heat by combustion, a heat pump transfers it. In winter, refrigerant in the outdoor coil absorbs heat energy that is present in the outside air, even when it feels cold, and the compressor raises that energy to a useful temperature so the indoor coil can release it into your home. In summer, the cycle reverses: the system pulls heat out of your indoor air and releases it outside, which is how the same unit provides cooling. The key components are the refrigerant, the compressor, and the indoor and outdoor coils.

This is why heat pumps are so efficient. Because they move existing heat rather than creating it from scratch, they can deliver several units of heating or cooling for each unit of electricity they consume. In Greater Vancouver, where winters are cool and damp rather than severe, there is usually plenty of heat in the outdoor air to draw on, which suits the technology well.

• Refrigerant absorbs heat from outdoor air in winter
• The compressor raises it to a useful temperature
• The indoor coil releases heat into your home
• The cycle reverses to provide cooling in summer

Defrost, Cold-Climate Performance, and the Lower Mainland

In a damp climate, frost can form on the outdoor coil in winter, so the system periodically runs a defrost cycle to clear it and keep heating efficiently. Mitsubishi Electric's cold-climate Hyper-Heating models are engineered to maintain output as temperatures fall, which is what keeps an all-electric heat pump dependable on the coldest, wettest Lower Mainland mornings.

For homeowners, day-to-day operation is simple: the system runs quietly and adjusts itself, and your part is keeping filters clean and the outdoor unit clear of leaves and snow. Anything involving refrigerant, the compressor, or the coils belongs to a licensed technician. As high-efficiency electric equipment, heat pumps may also qualify for FortisBC or CleanBC rebates and financing depending on the model and your home.

Frequently Asked Questions

How does a heat pump heat a home without burning fuel?

It moves heat rather than making it. Refrigerant in the outdoor coil absorbs heat from the outside air, the compressor raises it to a useful temperature, and the indoor coil releases it into your home, all powered by electricity.

How can a heat pump pull heat from cold air?

Even cool outdoor air contains usable heat energy. The refrigerant absorbs that energy and the compressor concentrates it. Cold-climate Hyper-Heating models are engineered to keep doing this effectively as temperatures fall.

Why does a heat pump run a defrost cycle?

In damp weather, frost can form on the outdoor coil. The defrost cycle periodically clears it so the system keeps heating efficiently, which is especially relevant in the Lower Mainland's wet winters.

Why are heat pumps considered efficient?

Because they move existing heat rather than generating it, they can deliver several units of heating or cooling per unit of electricity used. Greater Vancouver's mild climate makes this efficiency easy to realize.
