If you're shopping around for air source heat pumps, you've probably noticed two main types: ducted and ductless. Both keep your home comfortable while saving energy, but they go about it in different ways. let's break it down.
Ducted Heat Pumps: The Traditional Route
Think of a ducted heat pump as the "team player" of the HVAC world. It uses a network of air ducts (the same ones you will see in central heating or cooling systems) to move warm or cool air throughout your home. It's basically a highway system for air, with ducts acting like roads connecting each room to ensure the house is an even temperature.
Best for: Homes that already have ducts in place
Pros: Even temperature in every room, hidden equipment (no bulky units hanging around), and quieter operation.
Cons: Installation can be pricey if your home doesn't already have ductwork. Plus, ducts can leak air over time, which means a little loss of energy and repair costs.
In short: If your house is duct-friendly, then this option is perfect for you!
Ductless Heat Pumps: The Flexible Friend
Ductless heat pumps, also called mini-split systems, skip the ductwork entirely. Instead, they use wall or ceiling-mounted indoor units to deliver air directly into the room. Each unit connects to an outdoor system, and you can have one or several around your home. Think of these indoor units as little personal climate stations, each one can heat or cool the room it's in regardless of the temperature of other rooms.
Best for: Homes without existing ducts, room additions, or anyone who wants to control room temperatures room by room
Pros: Easy installation, super efficient, and customisable comfort
Cons: The indoor units are visible, and the upfront cost can add up if you're covering lots of rooms.
In short: Ductless systems are all about flexibility and control.
Which One Should You Choose?
If your home already has ducts, a ducted system might be the best choice for you in terms of value for money. If not, or if you want the power to change the temperatures in seperate rooms, then ductless is the option for you.
The Bottom Line
Both systems are efficient, eco-friendly, and wallet-friendly in the long run. The main difference is whether you want to use ducts or go duct-free. Either way, you will stay cool in the summer and warm in the winter.
