I've noticed that if you don't have climate control on "auto" and turn up the temp then it heats up much quicker.

Previously I had the controls on "auto" by default each time I set off in the morning.



@ BooBoo why is a diesel different to a petrol in terms of heating up quicker? they all take heat from the exhaust manifold, don't think there should be any difference?

Having had a 1.4 petrol and now a 2.2 diesel, the heater gets "hot" after about the same time on both in my experience. I thought the diesel engine actually had a heating element on it?

Diesel is more efficient and therefore produces less heat.
don't think thats the right correlation

diesels are more efficient due to being a compression explosion engine and therefore all fuel is exploded (or more than a petrol engine at least). With the high compression gives the diesel naturally higher torque and less freely revving

petrol engine is based on ignition and is less efficient in principal when the spark plugs don't ignite all the fuel in the cylinder.

To me an explosion is an explosion, they both produce heat and exit the manifold (generally speaking) from where the fan system takes its heat.

I see we have an additional ceramic element though from Syx's post :)

The engines are far thicker & heavier so take longer to warm up.

Like gret steal anvil!

I guess that could be true if the fan sys took its heat from the engine block but from what I know from other cars the fan sys takes heat from the exhaust manifold :confused:

I'd have thought it would be fitted with a heater matrix, as part of the cooling system as most cars are.

Unless I'm wrong of course?

Even my petrol engine takes a long time to warm up especially when in long low speed limits. I find it comes on quicker if I turn it off until the engine is nearly up to normal temperature as the heating can even cool the engine. Using one gear lower and reving the engine a bit more makes it warm up quicker.

I see you are talking about how long does it take to warm up the engine, i know the indicator for temp of the coolant is not in the middle but a little under middle, thast normal too, right ? Some say that thermostat for the engine coolant can be broke or falters, soo engine takes longer to warm up, coss the fan kicks in earlyer than it should, but i was talking with a guy who owns a VW passat, i belive VW have those faults on the thermostats more often than Honda does, i belive ?!

Stick a bit off cardboard infront off the radiator that will soon heat your coolant up.

I have noticed that my diesel civic takes much longer to warm up and blow hot air than my previous petrol car.

I think it takes between 10-15 mins till the warm air starts to filter into the cabin.

Quite right. That's why the heated rear window is automatically switched on below 5 degrees on the diesel. It loads the engine a bit more to make it warm up quicker.
Didnt know that:)

How does that work?

Can't see how the heated rear windscreen puts load on the engine :confused:
it takes current from the electrical system but it's not making the alternator work any harder in mechanical movement?

Not like some aircon systems that engage a pulley onto the aux belt thus creating load on the engine.
