Window Type AC

This type of air conditioning unit is affordable and quite popular. They work the same as any other air conditioning unit. It takes out humidity and heat and blows in cold air inside the room.

They come with generic ease of access functions, such as sleep mode, timers, etc. Moreover, these units are known for cooling the room very fast. 

As a downside of this, window units also are a bit noisier than other alternatives. You can also switch between high cooling or high fan according to your desire.

Portable AC units

A portable air conditioner is an excellent choice for a radiator-heated house. You don’t need to deal with the effort of installing ductwork or any kind of installation.

This is why portable air conditioners are amazingly convenient. Portable air conditioners are ideal for houses with limited space. They are small and as a result easy to move around the house.

Single hose and twin hose systems are the two types of portable devices available. A single-hose device takes in air and exhausts it outside through a single exhaust pipe. 

A dual-hose system, on the other hand, includes two independent hoses for input and exhaust air.

Through the Wall AC Units

Window air conditioners obstruct natural light and ventilation. It might be a big reason for not liking them. If your home is heated by radiators, through-the-wall air conditioning can be perfect.


You can find some similarities between a through-the-wall ac unit and a window unit. The only difference is it’s installed in a wall rather than a window. Thus, they’re an excellent choice for houses with a restricted amount of window space.

Furthermore, they are more energy-efficient than window units. Because window frames are prone to air leaks, resulting in cool air loss. 

However, the hole in the wall for installation means a long-term adaptation. So choose this option only if this isn’t a major concern.

These units also come with the same kind of convenience functions as window ac units. You can also pair these units with smart AC controllers for more control. So controlling the environment and cooling can give you more comfort.


Can I Use Radiators to Cool My Room?

Can I Decrease the Heat of the Radiator Heating?

Radiators heat a space by using natural air convection. A circular air pattern is created by hot air rising from the radiator. Chilly air is drawn and heated by the radiator.

Is There Any Other Way of Air Conditioning a Radiator-heated House?

Yes. There is another way of air conditioning: a radiator heater house. A high-velocity air conditioning system is also an option. These systems employ standard compressors and evaporators.
