Now the winter is here I am finding that my heater takes ages to warm up.

Is there anything I can do to speed things up

Cheers

Petrol or diesel?

Location?

In the U.K., diesels are notorious for taking a long time to warm up fully;  20 min on suburban roads. It takes mine about 9 miles on a motorway style dual carriageway in winter. However, the heater starts to work a little bit before the gauge has come off the stop.

Ditto, a steep hill after the temp guage has moved a bit can cut many miles off the warm up.

 

It just shows how efficient diesel engines are compared to petrol also that they are running at full economy with no enrichment as soon as the glowplugs stop heating.

If it’s a petrol engine then there is an underlying issue most likely.

 

but diesels are bad, a fully working EGR helps, along with a healthy stat, most my diesels I’ve fitted radiator guards too during the winter, helps restrict the flow of cold air into the engine bay and over the rad, my current C6 has an electric auxiliary heater so I’m lucky because I get warm air within a minute or two when the temp is 0, my old C5 I had to have the rad guard fitted otherwise I wouldn’t get warm air until I got to work 😂
