You've heard of mini-split heat pumps, haven't you? That term often has the word 'ductless' in front of it because most mini-splits have no ducts. There's just the 'head,' which contains the evaporator coil and blower and is usually mounted on a wall (as shown at left). It's a 'mini-split' because it's a small split system heat pump.
You may also have heard the terms 'inverter driven' and 'variable refrigerant flow' and wondered what they mean and how they help. It's possible you even know about the ducted version of mini-split heat pumps, which get around the objection that the heads are unattractive.
Maybe you have other questions, too:
- How many heads can you have on one condensing unit?
- Are they really as energy efficient as they say?
- How well do they do in cold weather?
- Is it possible to use them to heat and cool a whole house?
If you'd like to know more of this hot technology, Energy Vanguard is holding a live webinar on the fundamentals of mini-splits. It'll be on 28 August at 2:00 pm EDT. Registration is limited to the first 100 who sign up and pay the nominal fee of $12. It looks like this webinar will sell out, so sign up soon if you'd like to get in on this.
