As the weather begins to cool and we start thinking about heating our homes, the question of which is the most efficient heat pump system – high wall or floor unit – often comes up.
There are pros and cons to each type of system, and the most efficient heat pump system for your home will ultimately depend on a number of factors, including the climate you live in, the size and layout of your home, and your personal preferences.
In this article, we’ll take a closer look at high-wall and floor unit heat pumps, compare their efficiency and other features, and help you decide which type of system is right for your home.
What is a High Wall Heat Pump?
A high wall heat pump is a type of ductless mini-split system, which means that it doesn’t require any ductwork. These units are typically mounted on an exterior wall, high up on the wall near the ceiling.
One of the main benefits of high-wall heat pumps is that they take up very little space – both inside and outside your home. They’re also relatively easy to install, and can often be done by a homeowner with basic handyman skills.
Another advantage of high-wall heat pumps is that they’re very efficient. Because they don’t require any ductwork, there’s no loss of heat due to ductwork leakage. And, because they’re mounted high on the wall, they take advantage of the “stack effect” – the tendency for warm air to rise.
The main downside of high-wall heat pumps is that they can be a bit noisy. Because they’re mounted on an exterior wall, you’ll likely be able to hear the compressor and fan running, especially when the system is first turned on.
What is a Floor Unit Heat Pump?
A floor unit heat pump is also a type of ductless mini-split system, but it’s mounted on the floor instead of on the wall. Floor units are typically located in the corner of a room, and they take up a bit more space than high wall units.
Like high wall units, floor units are also relatively easy to install and are very efficient. And, because they’re located on the floor, they’re less likely to be affected by the stack effect, meaning they’ll be just as efficient in heating your home as a high wall unit.
The main downside of floor units is that they can be a bit more difficult to install than high-wall units. And, because they’re located on the floor, they’re more likely to be in the way, and you may have to move them when you vacuum or clean the floors.
Which is More Efficient – High Wall or Floor Unit Heat Pumps?
Both high wall and floor unit heat pumps are very efficient, and which type of system is more efficient will ultimately depend on a number of factors, including the climate you live in, the size and layout of your home, and your personal preferences.
In general, though, high wall units tend to be a bit more efficient than floor units, due to the fact that they’re mounted high on the wall and take advantage of the stack effect.
If you live in a climate that’s particularly cold in the winter, a high wall unit may not be the best option for you, as the stack effect will cause the unit to work harder to heat your home. In this case, a floor unit would be a better option, as it would be less affected by the stack effect.
The Bottom Line
When it comes to choosing the most efficient heat pump system for your home, there’s no clear winner – it ultimately depends on a number of factors, including the climate you live in, the size and layout of your home, and your personal preferences.
If you live in a mild climate and are looking for a heat pump that’s easy to install and takes up very little space, a high-wall unit is a good option.
If you live in a colder climate and are looking for a heat pump that’s just as efficient as a high wall unit, but takes up a bit more space, a floor unit is a good option.
And speaking of bottom line, it is well worth keeping an eye out for heat pump specials, as you can typically save 10-20% that way.
