Picture of How to bleed and restart your oil heating.
A guide to restarting oil heating boilers after they've been off for a while or the oil has run out.

Yeah, I've been getting to do plenty of this lately.

A lot of people don't know how to do this when they first move out or in to a house with oil heating after they've used gas or electric all their lives...

Step 1: To the boiler...

Picture of To the boiler...
Go to the oil tank and make sure there's oil in it, or you'll be wasting your time...

You'll need either a small spanner or Allen key, in my case it's an Allen key.

There'll be a red button, often lit up on the front. Make sure the heating system is in the "on" cycle and press the button, the boiler will start doing things and trying to fire up.

Don't be too disappointed, it's very rare for you to get lucky but it has happened to me and it seems to help get the fuel moving a little bit.

Hi - could anyone please tell me the minimum amount of Kerosene I woudl need to buy to test a boiler. I am thinking the boiler is not working so do not want to spend money buying lots of Kerosene until it is fixed or replaced as will not use heating until December really - help - just want enough to be able to test the system?

Check the tank, you can tip them a bit towards the outlet a little - just don't strain the connector, a 25L "emergency or topup" drum should get you going if there's not enough for a test with it tipped, plus it's kind of hard to buy it in lower quantities.

If the cap's been off the tank any length of time it'll need drained first though...

F...King fantastic. It took a few more than 10 attempts but I just persevered and it worked! simple sound advice

My local heater specialist charged me £100 each visit.. This has saved me potentially and literally 1000s

A BIG Thank You!

Wow, does this bring back really bad memories :-) At one apartment I lived at with my first wife, I had to do this, and prime the oil pump every fall after it got cold.
killerjackalope (author)  Goodhart6 years ago
Oh joy, had one that had a little pump to prime it because the line would empty completely and the oil wouldn't flow under gravity but not that actual boiler...
