please tell me how to change a radiator in my house?

Answer 1

ya better off getting a plumber in wont cost much. i got 1 done not so long back got charged £20

Answer 2

Basically you turn off the valve at each end (one is often under a cap as it is only used at this time), undo the big nuts that hold the valves to the radiator, slightly pry the joints apart so that the valve is clear of the radiator at both ends (be prepared with bowls and towels to catch the water that will drain from the radiator at this stage), then lift the radiator off its wall mounting. To fit the new one, do everything in reverse. You need to pay attention to getting a water-tight seal when you reconnect the valves, PTFE packing tape is often useful, wound generously around the thread. The whole job need only take half an hour.

Answer 3

right, i had to change 22 of these buggers in our hose... bloody nightmare, ...

follow these steps

1. close the valves on eachside ( there the ones on top...usually turn the white things... but you may need pliers.

2. slightly loosen the main fitting into the radiator... and i mean slightly...remember that its full of water!!! so you'll have to drain it... (good idea to put towel down as well just incase you spill a bit

3. once drained down undo the fitting fully (carefull there might be a tiny bit of water left in.

4. lift it off the wall ( a good way to stop ant tiny spillage is to flip the radiator upside down once off the wall)

5. get a new radiator out of package

6. lift the radiator back onto the wall (make sure it's clipped on to the backets)

7. put the main fitting back together...... tight! so it doesn't leak!... get some PTFE tape and wrapp it around the fitting..... it helps seal it.

8. make sure they are tight, and then allow the water back into the radiator by turning the white knobs again ( or getting the pliers)

9. job done


hope it helps......


GET THE RIGHT SIZE RADIATOR, SO MANY PEOPLE GET THE WRONG SIZE!! MEASURE IT FIRST ANS SEE WHETHER ITS A SINGLE FIN OR DOUBLE FIN

good luck

Answer 4

Most of these answers scare the Hell out of me, as I'm a plumber.
You did'nt say why you wanted to change it.
Do you wish to replace because its old fashioned, and you have seen a modern convector.?
Was it leaking.?
You wish to replace because you fancy a double convector,as it gives out double heat .
If it is your intention to replace like- for- like, there should be little problem. Turn off the valves on each end of the rad, and get a friend armed with a bucket, and a roasting tin from the kitchen, to catch the water that will run out when you remove the rad
Using a wrench, undo the nut, catch the water in the tin, be careful as the valve has a tendency to rotate,. Undo other valve. Lift rad off brackets, and immediately turn upside down and out the door.,
If the rad that you intend fitting is either a` double or a different size call a plumber.
If black water comes out , put FERNOX inhibitor into the system
this is magnetite, black rusr from YOUR radiators.
Try not to drain the system, new water contains too much oxygen..

Answer 5

Depends on whether you have a combi boiler or hot water storage tank.
Combi turn off water and boiler drain system (use old hosepipe to outside or drain) undo radiator valves with Stilson or equivalent replace radiator use new olives and PTFE tape on valve switch power and water back on and use fill up loop to regain water pressure in system
Hot water storage tie up ball **** on tank switch off water and boiler drain system replace radiator as descibed switch back on and untie ball **** bleed radiators to release air

*** radiators will still have blackish water in them protect carpets and introduce corrosion inhibitor or better still find a plumber

Answer 6

you have three choices drain down the system or close the valves at each side of radiator and disconnect radiator after emptying it 3rd leave valves on radiator and freeze pipes and disconnect depending on size of radiator if full of water it will be heavy If you drain down system it gives opportunity to renew inhibitors and get any gunge from system

Answer 7

switch off boiler and controls, tie up ball valve in header tank (smaller one of the two ), find a drainvalve and attach a hose to it and feed outside. place a towel underneath the valve and open it clockwise. after a few mins, open the bleed valves on upstairs rads and then the downstairs ones ( test first ). when water stops from the hose, you should be safe. hold the rad valve upright when you loosen the nuts. filling is the reverse
hope this helps
