I get heat from the heater long before the engine is up tp temperature. Why turn the heater off?

The newer diesel engines are running more efficiently, so actually produce far less heat than they used to. Thus they do take a bit longer to get up to full working temperature. I've noticed this particularly in my current 308.

If the engine is not getting warm after a couple of minutes then the thermostat is stuck open and needs to be changed, providing the system is full of water/antifreeze mix
Does the heater inside the car get warm or hot after a couple of miles?
if yes then everything is ok.
if not then you need to change the thermostat

That's wrong. Diesel engines can take about 10 minutes+ to get warm. What you might be thinking of is electric heating elements giving you the illusion the engine is warm because you have warm air coming from the vents.

25 minutes seems excessive though.

mmm,didn;t realise that newer cars had electric heating elements as well, but I suppose that is how you clean the windscreen quickly.

My 2008 is a very early 2016 model on a 65 plate. It has the dual zone climate system and when badly fogged up I use the auto windscreen button which redirects all air to the screen, puts the blower on max, heat to high and aircon on.

I never really understood why some owner handbooks suggested using aircon to demist the screen until I had an aircon specialist out when the 308 aircon stopped working. He explained that using aircon while setting the heat to high blew the air over the aircon matrix which removed the moisture, turning it to ice on the matrix then the dry air was heated. It is the moisture in the air inside the cabin that cause the screen to mist up.

It makes absolute sense once it had been explained. I just didn't figure it out for myself as I had only had aircon once before for a short time.

My wife's 2008 1.6 Diesel took ages to get up to temperature (approx 5 miles). I spoke to the dealer and was told "It's characteristic of he model"!
She now has a 1.2 petrol 2008 and it heats up in about 0ne mile.
