Freelander 1 Heater

Hi
Heater in my td4 only getting like warm. Blower working fine! Any ideas much appreciated
Cheers

Is the engine getting to normal running temperature?
Is the FBH running, if one is fitted?

im having the same problem but have been told its my thermostat
my temp needle only goes a 1/4 of the way up
im fitting a in line thermostat there are quite a few threads on here about it

Definitely a nice simple and cheap mod to improve the heater output.

Hi nodge
Yes engine running up to normal temperature. I'm not sure what fbh is or what it would look like
Cheers Shaun

I'll look into that but the needle on mine goes up to half way an stays there so I'm guessing thermostat ok thanks tho.

If the temperature gauge is getting to the mid point, then the engine is at running temperature.
To get the highest temperature out of the heater. Set the temp control to full right (hottest) position. And the distribution control to any of the off screen positions. Setting to a screen position will activate the AC automatically, which reduces heater output slightly. However setting the distribution control away from the screen can cause screen fogging. You can also increase heater output by selecting the recirculation mode. If recirculation mode is used, then move the distribution control to the screen/floor setting. This will activate the anti-fog function (turns on the AC), so window fogging is minimised.

There are a couple of tricks that LR used to increase heater output, when the outside temperature is low. There was a standard fit, later an option to have a Fuel Burning Heater (FBH). This is basically a tiny oil fired boiler, fitted under the LHS of the front bumper. It's plumbed into to heater circuit and set to activate automatically when the outside temperature is below 5°C. This boosts heater performance and helps warm the engine up faster.

The other trick LR used was to install an electric heating element in the heater assembly. This is known as a Positive Temperature Coefficient (PTC) heater. It basically uses large amounts of electricity from the alternator, converting it to heat. This then assists the water heater matrix in boosting heater output. The PTC has low electrical resistance when cold, using lots of power. As it heats up, its resistance increases, so uses less power. This regulation is automatic and part of the PTC's design.

So for diagnosing poor heater output, you need to know which system you have, and go from there.

Thanks nodge
That's brilliant information thank again for your time an effort
