Twine on a Defender Tdi

Darren,

Some things to check.....

Deisels sometimes run alot cooler than petrol in the heater water circuit...check temp of heater water after 45min run time.

Check heater controls on dash maybe position of controls has a bearing on temp and diversion of water in relation to where you placed the twine in the heating water circuit.

Check the direction of the water flow for the heater water and the shower, i don't know about the Twine, i have a helton and i connected the shower up the wrong way round, also some newer cars need to have the motor reving a little higher.

Hope this helps,

Baz.
Ps, the speed of the flow makes a difference too.

Hi Darren, If you have the exchange in the heater circuit, check the tap is turned to hot (on your dash), as previous replies above and you may need around 1500 rpm, failing everything ring John from Twine, he has mentioned on this forum b4 that he can supply a longer unit (about 65mm longer) which would be better , assuming you have the room. You need minimum 45 degrees or hotter if you have no shower enclosure and a wind chill factor. Forgot to mention, you may have to reduce your flow from your shower head to achieve the required temp, possibly down to 3 litres per minute.. Hope i have been of some help Best regards Michael

I had the same problem with my 4.2 GU. It is critical that it is bled correctly. I fitted the longer exchanger and it made a difference, not much but it all adds up. A mate has one on an 80 series and it is hot off idle but I need to run it at 1200 rpm and that is pulling water from the King river which is brass monkey stuff. Give John a ring and He will gladly assist in fixing your problem as he did with me. It does make a difference slowing the flow down a bit.

Cheers

Hi Darren,
I had the same problem with mine, just wasnt getting hot enough in winter. Problem fixed though with a simple cover over the front of the grill, reduced air flow through radiator while sitting around 1000 rpm, and on cold winter nights, i would slide a piece of cardboard down infront of the radiator, that got the old girl steaming. Now i enjoy hot showers every time....and i didnt even have to istall a rheem !!!
Regards....clean Angelo :-)

Hi

We have a TD5 with a Twine, we need to run at about 1500 rpm, works fine.

Cheers

Another issue I had was the pump was too good. Pumped the water thru to quickly . . . didn't get hot enough.

I'm going to reinstall mine on a seperate circuit with its own tap.

I had similar problem with pirahna unit
Couldn't work it out and had pirahna scratching their heads
As previously mentioned either had an air lock or coolant level was too low
If exchanger is fitted higher than radiator tank make sure coolant level is full
Now works fine after topping radiator up

Happy showering

I found in winter I had to recirculate the water in the bucket for a couple of minutes to get it really hot for Lex, me I don't care to much.

Thanks guys, we drove the car around today and the hoses heated up quite a bit, maybe showers will be best after a drive rather than from a cold motor set at idle. Thanks for helping, will keep trying and post what we find. Thanks, Darren.

Hi Darren, As a matter of interest, how long is the barrel of the standard Twine unit, not including the fittings, The Helton unit is only 170mm long plus the fittings hanging out the end. On their respective web sites the Twine looks much longer in the photos but no length mentioned. Michael
