Already increased CAL but still had to turn flow up Cal is set at 23 and Flo is 27 overnight temps are 1 deg and day temps have been about 4-8 degrees . Mike

These numbers are good and lower than i expected, It just shows each system is a little different as are the needs of the user. The Controllers are very versatile and have a wide range allowing them to Calibrate to pretty much any set up.

Cheers

Yes it has a 3 pin plug 230 volt. I used to to spread the heat and you will have to make a water proof join in the wire I used that tape that seals its self cant remember the name the covered it in silicon  block around the joint. I put them in at night and the water was 33 degrees in the morning and if you cover the tank with silver insulation it will keep it heat till lunch.

If you go to a aquarium centre they should have a heater that's completely submersible including the power cord. The cords on these are double insulated and designed to be submerged as some need the heater close to the bottom of the tank. I was looking at these at the weekend at a centre and spoke to the assistant about them. Some are designed to just have the metal or glass heater part underwater and others the whole thing. Can't be too careful when it comes to electricity. Interesting and helpful info above re the heat, it will help me choose the right wattage element...thanks.

I got a totally submersible one from ebay last year.

Hi ian my settings are lower as i use 1mm Jets so inevitably my settings are lower than most , One question though is their a recomended difference between the Cal Setting and the Flo setting .

So if i set my Cal at 30 can i set my Flo at 30 as well . Thanks Mike

you can do everything possible to stop them freezing overnight, but if you have micro/minibore, if its still freezing in the morning, the water will freeze inside it when laid on the ground!!!

Oil filled rad overnight, then start later in the morning, just wait for the temp to rise a little.

I worked last year with nearly 100 mtrs of hose laid in 4" of snow and the water never froze in the microbore hose.
What I do is keep the water flowing even just very slightly to avoid it freeezing up. 

good advice .......... I found if you laid it on concrete / tarmac if would freeze easierthat if it was laid on snow plus keep it trickling as you say .

Snow acts as insulation when you think about people have survived in snow holes in freezing temps . got to keep the flow going i have had water freeze in hose even when temps have risen due to the fact the ground temps are much lower . Mike

Fish tank heater: you will need 200 watt per 100 liter tank. The aquarium fellas will tell you less but we need to heat the water they do not want to cook the fish.

A gas on demand heater like the "fogwash" is brilliant in the winter. Turn it down low to avoid thermal shock,.. but you can work away down to -6 or -7 without pipes freezing.

Obviously its not clever to be spraying water over footpaths at those temps, so it try to do work where I know there are flowerbeds under the windows (and trad doorways) until it warms up a bit - just use common sense & you'll be fine.

If you combine one of those heaters with a frost protect controller then you can protect your van system from freezing too,.. just re-circulate the hot water back to your tank & it'll act like a big radiator.

if you are di only . just fill your tank up with hot water in the morning . stays warm till about 2 . no problems at all last year .

do u have hot water tap outside? does it affect the resin?
