Myriad & Myriad+ Multi-Zone Heat Pump Systems – Frequently Asked Questions
Are Myriad and Myriad+ heat pumps suitable for Ottawa’s cold winters?
Short answer: Yes — both are built for true cold-climate performance.
The Myriad and Myriad+ multi-zone systems are engineered to deliver reliable, efficient heating even when Ottawa temperatures drop below -25°C. With inverter-driven Moovair technology, they maintain up to 100% of their rated heating capacity at -20°C, ensuring steady, comfortable warmth all winter long.
What’s the difference between Myriad and Myriad+?
Short answer: Myriad+ is the enhanced cold-climate model.
Both systems provide multi-zone comfort and energy efficiency, but Myriad+ offers higher low-temperature performance and advanced inverter control. It’s the preferred choice for Ottawa homeowners seeking top-tier efficiency, quieter operation, and optimal heating in extreme weather.
How many zones can a Myriad system handle?
Short answer: Up to six independent indoor zones.
One outdoor unit supports up to six indoor units, each with its own temperature control. This flexibility lets you heat or cool specific rooms individually — ideal for homes with different comfort needs across levels or additions.
Can I combine ducted and ductless indoor units?
Short answer: Yes — that’s one of Myriad’s biggest advantages.
Choose from six indoor unit styles, including wall-mounted, floor-mounted, ceiling cassette, and slim ducted options. This allows you to mix ducted and ductless zones for a truly customized comfort solution throughout your home.
Do Myriad heat pumps work efficiently in summer?
Short answer: Absolutely — they provide high-efficiency cooling too.
In addition to powerful heating, Myriad systems deliver smooth, quiet, energy-efficient cooling during Ottawa’s humid summer months. The inverter compressor automatically adjusts output to maintain steady indoor temperatures and reduce energy use.
Who manufactures Myriad and Myriad+ heat pumps?
Short answer: Moovair — a Canadian brand built for Canadian climates.
