Radirators can be very trickey to get working.

Starting by purchasing your waste oil heater with the copper coil fitted. Or a log fire with a wetback fitted which is converted to waste oil burning to get free heating.

You need to plumb it up using an Ajax Valve teed on the cold side of the coil, which is the bottom of the coil.

The Ajax valve connects to the town supply water, to keep the closed loop full of water all the time.

An open vent is needed, extending at least 2 metres above your radiator, this needs to be teed into the hot side of the coil, being the top.

Fill the loop up with the town supply water. Turn the Ajax pressure screw until the water exits out the top of the open vent, then turn it back one turn. Stopping the water from flowing out the vent. This is called the water head.

Next is bleeding the air out of your radiator, until only water exit the bleeding valve at the top end of the radiator.

Light the heater, The heater needs to be running at 400C to heat water around 85-100 degrees C.

If your using a pump turn it on to circulate the water, or you will hear a few bangs as the hot water trys to move the stubbon cold water, if your using thermosyphon system. This is the noise of the water being pushed up the pipes, it will stop once the water stars moving.

If the bangs carry on, then there will be an airlock in the radiator so bleed the radiator more until only water exits.

If nothing comes out the bleed valve, then the Ajax Valve needs to be turn on further until it does. 

 If you plumb up a radaitor without an Ajax valve or an open vent you are creating a bomb waiting to go off, yes it will cost abit more but then you know it's been done right.

Hard to see, I'll take another photo of it so you can see it better.

You can see the Ajax valve which i connect to the garden hose to. This connects or Tees into to the bottom of the coil which connect to the pipe exiting the heater.

The open vent which is a 15mm copper pipe with the end at the roof level cut open can just be seen teed into the hot water exiting the heater next to the fibre light sheet. Very simple and easy to do.
