I have a 2012 RRS which I've had for about 10 months now. The other night it was cold so turned the heater up to 28 and it soon became warm so backed it down to 25 and it started to feel cool in the car, back to 28 and hot air coming out the vents on both sides of the car turn down to 25 and again the temp of the air coming out of the vents felt more like I had put it on to 18 degrees
Has anyone else had any issues with heater temps ? 2017 SVR. SVO Scafell grey Ebony interior

I used to work in an office where the girls used the room thermostat like that - they never understood why it was always too hot or too cold. I tried to explain but was wasting my time.

As for your car - it sounds normal. There is absolutely no point in turning up the thermostat expecting the interior temp to increase more quickly. If you turn it up to 28 it will quite quickly get to 28, which is too hot. If you then turn it down to 25 the climate control will invoke the air conditioning to cool the interior - which is why you feel cold air coming out of the vents.

Just set the temperature you want and leave the temp control alone.

No woman I have ever met understands this. On getting into a cold car they will always turn the thermostat up to max in the belief this will heat the car up more quickly then when it is sweltering they will turn it right down and so the cycle of hot and cold continues. Just to make things worse they also switch the fan blower off because they don't like the draught up their skirt.
This just makes the time taken to reach the selected temperature longer. Do not try to explain why they are doing it wrong - it will only start an argument. Same applies to switching on the headlights before starting the engine. 2008 MY Java Black TDV8 HSE

It was nothing to do with turning it up high to try and warm it up quicker. I had been outside for longer than expected so turned it up high to warm myself up but once I had warmed up I turned it down 3 degrees and got cold air blowing out at me when set to 25 degrees.
Been out in the car today and at 22 degrees it was blowing warm air so not sure what was going on with it the other night.
My parents borrowed it the other day and said the heater seemed fine all the time they were using it.

So I'm thinking it was just having a funny turn and will be ok from now on. 2017 SVR. SVO Scafell grey Ebony interior

Read what paddi said you jumped in your car and turned the heating up to high ie 28, the reaches that setting you then turn it down to 25 so the car introduces the cold air to drop the temp down to 25 as quickly as poss.
Dangerous ground there paddi, but true offen have this conversation with the wife as she turns the heater to max with a cold engine  2008 G4 RRSport TDV8 current

Just wanted to add my Support to Paddi’s comments. I’ve been through all this and came to the same conclusion. Just not worth arguing with “better” half about thermostats. It just raises the temperature  Robin

No the Eco button just means the aircon won't run as much but it still cuts in and out. I dont have the eco button in mine, I'm guessing you do with the earlier dash. 2017 SVR. SVO Scafell grey Ebony interior

Ah right, ok. Yeah I have it in mine. Steve.

From the manual:

"With the engine running, press the button (7) to put the air conditioning system into Economy mode. This turns off the air conditioning compressor which reduces the power consumed by the system and system performance. Prolonged use may cause the windows to mist."

So I understand this to mean that its like an old car heater system. Still provides heated or cool air (depending upon the temperature setting) but not "conditioned" so not cooled below ambient outside temperature or de-humidified. Robin

That's what I read  Steve.

The Eco button turns off the AC that's all. Heating and everything else works just the same as it would normally.
