I would either get a 12V electric heater or get an inverter and use a 230V heater.
TD5 is not much better than you have.  |

Make sure the cables are adjusted properly, mine is so hot I normally have a vent open! 2015 RRS Autobiography SDV6

I was about to post that.
If it's never been looked at check its set up properly - overtime they do seem to go out of adjustment, I don't know if it's the cable stretching or slipping, but check its fully opening. If that doesn't work it may be worth checking the core in their is in good condition. If they are in good condition I think the old Land Rover heaters are good - perhaps a bit slow to heat up (maybe particularly on a tdi?) and with a few droughts to overcome  - but it should be good enough.

I took mine to bits last year and found the heater matrix was a bit blocked. Massive difference once flushed through.
Also swapped the mud-encrusted original blower for a "bilge blower" type of fan - much improved air flow. No problems now. --------------------------------------------------------------------------------------------------

Tdi heaters are fine and more than adequate for the job. Usually a combination of factors makes them ineffective, generally down to neglect and lack of maintenance.
Check cable adjustment. Ensure all seals are in place so you aren't losing hot air. Ensure matrix is clear both internally and externally. Ensure engine thermostat and cooling fan are operating correctly. Eliminate cold draughts from body panel gaps etc. |

Agree with above. My 300tdi heater is very toasty, even when I have taken it to places like the Alps in winter.
If it is working properly and you have decent door seals then it should be fine. If you want to upgrade it then Allisport do an updated matrix but I don't have any experience of these to comment on how effective they actually are. |

As above, standard heater is fine as long as the cooling system & heater controls are operating as they should.
My 300TDi soft-top is my daily driver yet the heater is so effective that after the initial warm-up period I often have to turn it down as the cab gets too hot (viscous fan fitted, rad not blocked off etc etc). If the engine is reaching normal operating temperature (if it isn't, find out why not) then practically the same heat should be available through the heater vents (allow for a few degrees loss as the hot air passes through the ducting). ONE LIFE, GET IT! |
