What they do is to connect your bathroom radiator to your central heating pipes at an angle (around 90 degrees)

Straight Radiator Valves

It is called straight radiator valves because when connected to your radiator, the water is not directed, diverted, or distributed at any angle when flowing. It just flows straight. There is no bend or curves with this type of radiator valves. Meanwhile, it is usually connected horizontally from the floor. To do this, the pipework must have to run along the wall and directly into the radiator without any curve or bend. Also, if your pipework comes straight up and out of your bathroom floor, using straight radiator valves is best to ensure your heating works efficiently.

H-Block Radiator Valves

One advantage of using H-Block radiator valves is that it will minimize the impact your heated towel rails have by leaving some space on the appliance side. This type of valves is best used with central or middle connection radiators to minimize the impact your heated towel rails have. Another advantage of using H-Block radiator valves is that it is simple to install. It is also very easy to remove and replace than other valves.
