Your door locking issue is *probably* just a well known feature of the 10AS alarm unit.
They like locking you out. If you ever need to leave the engine running put a window down. Thankfully mine doesn't have central locking and the farm one has only ever locked me out in the yard. It seems to do it for a lot of people at the worst moments. There are people on here that have had to smash windows to get in. But if you've got the rear quarter windows, they just pop out very easily with no damage, you climb in through the rear door and off you go. My 2.4's heater works fine  although not all of my Defender is currently in my good books  |

If you're sitting idling then the engine will cool down, especially with the heater on and on a cold day. There's not enough heat being generated by the very small amount of fuel being burned and so the heater (along with the natural heat soak off the block into the cold air) is able to take more heat out than is being put in. Hence the engine cools down.
On my (albeit 200Tdi - but the same principles apply) Defender I often find myself coming down a long hill in the forest where I might be doing 20mph for 4-5 miles but just on the overrun (i.e. throttle at neutral position so injection pump cuts off fuel supply). In the winter when I have the heater on the engine temperature drops dramatically during this period. As soon as I get to level ground or an incline where I have to accelerate again it's then back up to temperature fairly quickly. As for your journey, taking 25 mins to do 8 miles you must be going reasonably slowly. You will need to work the engine on cold mornings for it to heat up, a downhill journey will not put much strain on the engine and it simply won't heat up. Any time you're on the overrun going downhill you are not injecting any fuel so the engine will be cooling down. Take it on an 8 mile journey with some hills (or sections at a decent speed - 60mph or thereabouts) in it and see if it warms up any faster. |

This is what I do on my new 90, helps greatly. My old 1959 beetle is exactly the same, open the quarter window though and it closes first time every time! |

I've got a 90 2.2 and during the cold days last week (-15°C) I was able to get the temperature only half way up to the middle on my 10 km drive to work (approx. 20 min). Usually, if it is only around 0° I'm not having too many issues getting the gauge to the horizontal position.
It really depends on how hard the engine has to work until it gets warm, but on the inside I'm getting first signs of warm air after 3-4 km. On the other hand and to my suprise it stays fairly warm for quite an amount of time after turning the engine off. I would even say that one hour after turning it off with a warm motor the indicator is still halfway up to the middle. Something which would definitely help getting the engine temperature up would be a radiator cover. |
