That doesn't sound all that normal, my 200tdi one sits nicely in the middle all the time and heaters work quite well.
I did have some similar symptoms on mine a few years ago and it was sorted out by replacing the engine earth strap, not quite sure what that has to do with it but it fixed the issue, so might be worth checking you have a decent earth. No doubt someone who knows what they are talking about will be along in a bit.

Normal operation for a Defender temperature gauge (at least up to and including Td5 models - can't speak for Tdci) is for it to rise to half-way (or just under) and stay there.
Earth is a good shout, but the heater issue is more worrying. Are you losing coolant? |

I don't think so, I'll have to have a proper check tomorrow in the daylight. I wouldn't be surprised if the heater was just due to controls not working properly as I was playing about with them a bit where I haven't had it long, today was the only time I've driven it long enough to get any heat at all!
I'll have a look at the earth strap tomorrow too as its it's too dark now, the car has a 3 month warranty as I bought it from a dealer but if its a simple fix I'd rather just do it myself, failing that Ill have to take it back but I wanted to be sure that it wasn't normal. How often should the engine be getting hot enough for the fan to kick in? |

Unfortunately I can't answer that one! A thermostatic fan is not a standard fitment, so it depends what temperature the thermostat is set to. When I used to have a thermostatic fan (using an X-Engineering X-fan controller), it never used to come on under normal working conditions. Pulling a big trailer up a steep track would see it on, but it never triggered during normal driving where there was good airflow over the radiator. |

My 200tdi takes a while to move to the center and if it doesn't have to work much and I put the heater on full blast it will go down to about a kwarter
 And it has an electric fan which is always off in these temperatures. Scaling the real deal. |
