A radiator which is coldatthebottom but hot atthe top will not be heating your home effectively. This means you’ll either be feeling cold or you’ll be turning the thermostat up to try and compensate for the lack in heat.
Radiatorsthat are coldatthebottom are full of sludge, especially if the cold patch extends higher in the middle of the radiator.
Radiatorsthat are coldatthebottom and hot atthe top can be caused by a build-up of scale, rust and sludge over a period of time. A mixture of these materials can cause a blockage and obstruct the flow of water. To rectify this, you'll need to flush your radiator.

Keep in mind that when the car is fully warmed up, the coolant (in the engine) will at least reach the boiling point of water. This is why cars use a 50/50
Thebottom hose should be at least warm, and quite warm if radiator flow is good.
Whyis my radiator making strange noises? Radiator noises aren't usually anything to worry about. Different types of noise could mean different things.

The upstairs rads are fine but downstairs they are hot atthe top and sides but cold or cooler in some cases in the middle lower 2/3rd of the rads.
On traditional “bottom-up” automotive engine coolant systems, the lower hose runs to the water pump’s suction side. As on any fluid system, suction
To control the temperature, the thermostat sits atthe end of thebottomradiator hose and directly regulates the flow of water through the cooling system.
In the event that the batteries are cold in one riser,that is, there is no heat in the radiators located one above the other, the reason for the appearance of an airlock atthe highest point of the system. In other words, the residents of the upper floor need to open a special crane...
If the leaking overflow pipe is at loft level or protrudes from the eaves of the roof, then the source is either the cold water storage cistern, or the smaller feed and
The wax will get too hot and go runny, it will then seep out and the thermostat will not work properly. This may be why your radiator doesn't warm up evenly.

Unfortunately, a coldradiator can also signify other problems.
Now, bleed the radiator using your radiator key, and put a cloth under the end of the radiatorthat you are working on. Air should begin to hiss out, until you see
Condensing boilers are the most energy-efficient boilers on the market today. They use less fuel and have lower running costs than other boilers.
Thebottom hose stays cold if the thermostat is closed, and the thermostat stays
Note that ALL The Radiator Shop radiators must be placed on the central heating system and never on the hot water system that feeds the taps i.e. a Direct system (which is separate). The water flowing to taps is constantly refreshed and its high oxygen content will rapidly corrode any radiator.
Another explanation for a radiatorthat is cold even though the heating system is switched on is the possibility that your thermostatic radiator valve needs to be replaced. We discussed earlier in the article that TRV pins sometimes get stuck into the shut position and can often be sorted out with a...
Flushing the radiator. Filled it with cold tap water. Let the car idle for 20 minutes.
Does your radiator feel coldatthe top and warm atthebottom? If so, air might be trapped and it may need bleeding.
Radiator warm atthebottom but coldatthe top. This is usually due to air in the system. Most commonly happens after you've had the heating off for lengthy periods.
Whyare my radiators hot atthe top and coldatthebottom? This indicates that the radiator may be receiving an insufficient flow of water; typically large radiators need a higher water flow than small radiators. There may be several reasons for this, such as incorrect balancing...
Why? If the vent were atthe very top of that last section, the lighter-than-air steam would close it
The radiator can go cold if the thermostatic valve of the radiator is turned off. Turn the valve on and the radiator should start working.
