One, do radiators have upper and lower parts?
Radiators have upper and lower sections. Before installation, it is crucial to distinguish which is the upper and which is the lower, as installing them incorrectly can easily lead to water leakage and damage to the radiator.
Two. How to distinguish the front and back of the radiator.
Observation method: The side with grooves is the front, and the relatively flat side is the back.
Touch method: When touching the radiator from the front, you will feel a recessed area. When touching it from the back, it will feel relatively flat.
Three. How to differentiate between hot and cold water for radiators.
Touch method: Directly touch the heating pipe supports with your hand. The support that feels warmer is the one with the water pipe.
Observation Method: Observe the upper and lower crossbeams. The pipe for water intake is located on the beam where the valve is installed. Alternatively, observe the main supply lines for heating, and the pipe with the filter valve is the water intake pipe.
Common sense approach: In normal situations, the inlet pipe is located above and the outlet pipe is located below.
IV. Please note the installation method for radiators.
When installing radiators, it is important to pay attention to the installation method. The two common methods are: either with inlets on both sides and outlets on the bottom, or with inlets on the bottom and outlets on the bottom. It is important not to have inlets on the outlet side and outlets on the inlet side, as this will result in the radiator being installed incorrectly and will affect its heating performance. Connecting with inlets on opposite sides is the most reasonable and beneficial method for water circulation.
