Is there a way to improve the heating in my Mini Mayfair. Input and heat. No matter how many hours I'm driving. I still only get a barely warm airflow. 

Thanks in advance,

Jonathan

Install a hotter thermostat. Make sure your coolant is fully topped up too.

Are the rubber ducting seals doing there job ?

To be honest it's not a fantastic heater in the mini anyway, although your heater matrix could be struggling to flow the water through due to a blockage.

Back flush the heater matrix, this should help to clear any grot however if the coolant mixture has never been checked and is a rusty brown colour then there is a good chance even back flushing will not sort it out. This will mean a new matrix and also possible a new rad.

My 74 clubby has a single speed fan heater and with its new matrix ( old one was leaking) it produces a lot of heat.

Also make sure you bleed the cooling system properly.    IMO, you should not need to fit a higher temp thermostat, the standard item should produce enough heat, and cool the car efficiently.

How do you know he has a standard thermostat fitted?

Also the thermostat may be old and passed its use by date, in other words weak and opening too soon. That would be the first thing I would do. Replace it!

Our SPi had the matrix blocked by dust, stopping airflow through it. Careful washing gave new warmth.

Also, how solid is the mini? I have one that's several oxidation events past its last MOT, and so much air gets through the cabin that the heater can't keep up. Check your condition and fit of all your door seals, windowseals, and firewall plates and grommets. Just replacing the carpets in my rusty one made it feel ten degrees warmer!

Thank you for the advice and the tip. Think It may require more than the carpets!

Thank you to everyone! My head is buzzing with things to try!!
