Cooling Rads

So use a condenserless packaged split unit from Powrmatic or others, and there is no external condenser to worry about.

I had a brief look and I'm no wiser how they work.

"A package HVAC unit combines multiple units, such as an air conditioner and heater, into a single unit. The unit is usually placed outside."

If it's placed outside I don't see any differenced from a split system in planning permission respect.

However, on most pictures I see the unit placed inside. In this case I don't see how it can pump the heat (in the cooling mode) from inside to outside.

ETA: I looked into installation manual. Basically, it's a common portable aircon, but fixed to a wall and not needing a huge hose, but still needing a big hole in the wall for blowing hot air outside. Still pretty noisy I guess.

It's a very common system in the USA but less common here. Two holes through the external wall (one with air in, the other for air out), and the unit sits internally, not outside. It brings air in from outside, puts heat into it for cooling, or takes heat out for heating, and then blows the air back out again.

I've installed them in my own house - I've got them
all running today with the heat, quieter than the fans we used to use and lovely and cool! Not very noisy outside either - much, much less noisy than the external heat pump I use for the pool.
