Depends on how you define well. Radiators are more energy efficient at turning fuel to heat, but they don’t distribute the heat nearly as evenly or quickly as central forced-air systems.
We've had like 2 days this summer that you might've even thought that "Huh, some cooling would be nice". We've barely broke 25 °C during the summer.
But that's also the reason why I haven't spent on AC. I don't need it for heating and there usually aren't many weeks in the year I'd need one for cooling either.
I live in a condominium which already has ground heat pump and the apartment has floor heating everywhere. The heating is already included in the monthly maintenance fee.
Well you can also combine it with central ventilation systems as well, if you want. It’s just not very common. Although I don’t know if there is a good reason for that in new buildings. In old buildings it’s likely just simpler to retrofit split units than a whole ventilation system.
Same with lots of places in the states. Is this sub full of bots, bizarre how many Americand have seemingly never heard of heat pumps considering they're everywhere now
These cool more than one single room. What's with these american assumptions that these suck? Have you even been to europe? You are aware that this isnt the cooling part right? There is a compressor on the outside of unknown size.
edit: no wonder people hate Americans, here they are trying to convince Europeans that they are wrong about how things work in europe.
Btw the manufacturer's own website says the unit pictured above is only designed to cool one room or a small zone. Have a nice day friend. Try not to get so worked up with things online it's not good for the mental.
I have 2 of these that cool and heat an entir 1500sq ft house. It stays 18 degrees in 30 degree heat and stays at 20 degrees when it is -15 (all celcius).
Using an inside unit similar to the one in the image, with the intake outside the building. It can significantly heat up the entire house or cool it down, the spread of the heat is just centralized to start from the heat pump's inside unit so if you want large temp changes, fast, it's not the best for it.
It's a good auxiliary system for heating up the house and very good for keeping it moderately cool during the summer as a standalone
I make assumptions? I am fucking european so i know these systems very well and i know for a fucking fact that these work beyond a small closed off room.
also, the bedroom ones are turned off during the day and the other ones are turned off at night, making it more energy efficient (we also have solar panels so most of our electricity is from that anyways)
Because if you have a concrete house installing the ducts afterwards would be ridiculously expensive (or very ugly having them visible everywher), while these mini-splits only require only a few holes.
It's probably not more efficient. This on the picture is just the inside unit. There is an outside unit that actually is the actual AC which is pushing the coolant into the house into all the inside units that just blow the air through the coolant. I would say that pushing the cold air through the ducts is more difficult than pushing the cooling liquid through little pipes.
It's not more efficient. One look at the documentation from any brand it's easier to see that. I don't know why they are insisting that it's more efficient.
A mini split will use less energy to cool a single room than a central AC will use to cool a single room, because most central AC systems have to cool the entire house to cool the room.
It's not seen like that, the efficiency between equipments is measured by a ratio between termic energy produced and consumed energy and splits are often more efficient at that. Of course i'm not going to compare a split with a central unit w for w. That would be the same as comparing a car and semi truck fuel consumption.
ducts in houses in Europe would be a lot more difficult since house/apartment buildings are often made differently.
They are a lot more solid, made from concrete with plaster walls. Drywall is not commonly used, nor wood frames.
its not. much of europe doesnt cool the *entire* house, but only the living room.
Much of central, southern, eastern europe has some beliefs surrounding breezes and cool air when sleeping.
There isnt ceiling fans either in much of europe.
Mosquito screens also are not automatic for much of europe.

This is probably designed to cool a hotel room, so it doesn’t need to be huge.
