My TD heater could be hotter, and clearly needs a flush, (The rad had a good flush through about 18 months ago while it was off), but I CBA at this time of year to remove pipes to do it properly. Can anyone recommend a good product to put in the system for a few days to remove some of the gunge. Or shall I just buy one of the "Mask the problems and sell your car" products from the factors?

I flushed my heater the other week, then filled the matrix with anti-freeze before re-assembly, filled it from the bottom inlet, slow process, but heater is still toastey hot.

Once of those jobs best done right

Of course, see CBA

[Doctor Gollum]

Best wait until spring then... job for when you're waiting for the pitch and putt to dry out

[Shackeng]

Well I intend to do exactly that. However I am looking for something that will give me a little more warmth in the cold weather in the interim.

[tigers_gonads]

Hot water bottle or a nice blanket maybe 

[Shackeng]

Thanks for all the suggestions, none of which, unfortunately, addressed my original question.
However, thanks to those who took the time to reply.

[Doctor Gollum]

Calgon tablets? Wouldn't like to say what the long term effects might be though

For automotive products, Wynns coolant flush could be worth a go, but read the label carefully. Also be prepared for the heater to get worse as it's a bit of a bottle neck, hence the suggestion to do it properly

Might be worth trying a domestic heating system descaler from Fernox (or similar)

Be very careful to check that whatever you use is suitable for use with aluminium. Also make sure that you don't leave it in for too long

At the end of the day Chris, it doesn't matter what you put the system unless the crap you manage to break up is flushed out 

For the record, Fernox works a treat if left in there for a day or two 
If / when you get around to doing the job, pour the fernox in and go for a slow drive to get it hot.
When dumping the fernox, sieve it slowly threw a pair of those old tights you used to wear under your flying suit to remove some of the silt then stick it back in the system for another go 
2 or 3 cycles should make a difference 

Until then, its hot water bottle and blanket time

Thanks for that, no tights left, so SWMBO's will do .

No secret here .. at -15C and 02:30 on a dark and windy night, pair of tights + long johns + flying suit was the order of the day ... RAF, in its wisdom, gave you a lovely cold weather parka that was toasty as hell ... from mid-thigh up ..... the lower extremities seemed to be ignored .. so it was a case of ... "needs must" .. then once airborne and the heating sorted, pop down the back and remove a layer or two ... 14 hours later, in the descent to destination it "might" be a requirement to pop down the back again and put it all back on .. depending on the forecast at said destination !!
