A normal radiator or towel it doesn’t matter. If the radiator is not fitted, then the tails will not heat up. Fit the radiator, if it’s the wrong way round, all you have to do is swap the rad valves round – I think the instructions will just be referring to the TRV’s, nothing to do with the radiator itself.
Does a radiator flow from top to bottom?
A vehicle’s Coolant flow depends on whether they’re in a year or make and model year, with the engine’s direction also impacted. From top to bottom, one of the most common directions of flow is from top to bottom.
Does it matter which side of radiator flow and return?
The vast majority of new TRV’s are bidirectional and can be fitted to either the flow or return, but it is always good practice to fit them to the flow side. If a non bidirectional TRV is fitted on the return side it will create a vibrating sound as the water tries to flow though it.
Does flow and return matter on a radiator?
Most modern thermostatic radiator valves are bi-directional – so can be fitted on either the flow or return pipe of your radiator. However, it’s always best practice to fit the TRV on the flow pipe that enters your radiator.
Can a radiator be fitted wrong way round?
If you fit the radiator in the wrong orientation it can result in a reduction of output, noise from the heating system, or even in extreme cases you can end up with a radiator that doesn’t do anything other than take up wall space.
How do you know which is flow and which is return?
Hire a laser hand held thermometer from a hire shop. Turn off the heating until it is cool. Turn it on and aim the laser alternatively at the two tails. The one that heats fastest/first is the flow.
How do you know which side of the radiator is Inlet?
Discovering where the valve inlets on your radiator are is fairly straight-forward and is defined primarily by the kind of radiator or heated towel rail that you have. With a heated towel rail, for example, you will normally find that the inlet position is located underneath at the bottom.
What happens if you get flow and return the wrong way round?
If the pipes are reversed, the sensor will record the lower temperature and could compensate to make up the difference. This can result in unwanted noise, or overheating and inefficiency.
Which side of a radiator should get hot first?
Your heating engineer will then turn the central heating on and note down the order in which the radiators heat up, those nearest the pump normally get hot first. If the pump is fitted inside the boiler then the radiator nearest the boiler normally heats up first.
Which side of radiator is the lockshield valve?
The lockshield valve, on the side of the radiator opposite the on/off valve, may be adjusted to balance the output of your heating system. The lockshield itself is the plastic cap that covers the valve to ensure that you don’t accidentally change the setting once you’ve adjusted it.
Do you bleed a radiator when it is on or off?
You should always bleed your radiators when the heating is switched off and the system has cooled down, because bleeding radiators with hot water flowing through the system increases the risk of scalds and burns.
Should both radiator valves be open?
You should open both of the valves on all of your system’s radiator when you are starting the radiator balancing process. You will most likely need to use pliers to open the lockshield valve.
Can you fit a radiator upside down?
yes as long as the air can escape when filling the rad, ie the pipes are running upwards all the way to an upstairs rad or air vent in the system, FatHands likes this.
