As experts are warning of very cold,below freezing weather,is anyone going to drain the heater?

I think this may be my fault. I turned on the outside tap yesterday in preparation for washing something. uncertain

I have drained mine down, but then again as Loto says, I worry if I dont have something to worry about.

No filled mine last week ready for the off , have an oil rad on day and night on low setting, makes it warm and cosy for when I need it, which is nearly everyday. is my  everyday vehicle. my water heater is under the off side settee, has a carpet / felt cover on the compartment, which AS put in, and the heater is less than two foot away so will not drain it.

I think it's more of a wind-chill problem rather than minus figures, or is it even colder than hereabouts?

I've been cycling in shorts since the beginning of March but had to go out early this morning so opted for three-quarters.
My legs were fine but when I got soaked in the hail/rain/sleet my poor old fingers (riding in fingerless mitts) were unbelievably painful.
Got another weeks touring coming up soon and hoping Snowdonia doesn't live up to its name.

Well we've had snow/sleet/hail here today so can't promise what Snowdonia will have. We're off to Cornwall at the weekend and it looks like being totally different to when we were in the same area at the same time 40 years ago (the start of the hot summer of 76)

Right now it is windy on the north coast but much milder on the south coast Paul, it isn't going to match '76 but not looking too bad and not too busy at the moment either. Will be keeping a look out for your van if you are down this way! Have a safe journey. up!

Thanks Groundhog. We'll be at Tregurrian C&CC site from Sunday.

Nobody has answered your question Micky. I will! I haven't put any water in yet and am glad about that. Drained down in November. I go away every month for a few days but cope with using sites facilities to save filling up the van (except the loo). I'll be filling up in May I hope. shiver

Talking of wind chill I've never been able to get an answer about the effect of the slipstream passing under and around van tanks. For instance I know that wind chill can make actual temperatures feel much lower, but does it actually change the temperature? By that I mean that if it's, say, 4 degrees and a van is driving at 70mph will the tank freeze? Certainly if we were tied to the outside of the van we'd feel temperatures well below freezing and therefore presumably the exterior of the tank would too, but would it actually be below freezing?

I did Rose, near the beginning of this thread, I filled up last week and haven`t drained it. have oil rad  on low setting, in all the time I am not using it .

Andy.   Quick answer is No.

Ian, when he is back will explain. It has come up before ,if you can find it on the search facility.

Wind chill: 

 1   Conducting heat away from a hotter body by a cooler air flow. ie. car radiator or human body. Temperature will not go below cooling air temperature.

 2.  Evaporation.  If the body has water or other fluid on its surface the air flow may cause evaporation which may lower it's temperature to possibly way below the air flow temperature.

Hi  wave

Yes, but that’s one of the classic simple questions that has a very complicated answer because there are so many factors at work.

Unfortunately there is no real single definition of wind chill but I assume we’re defining it as the ability of an airflow to take the temperature of a surface below the temperature of the moving air.

Moisture is the key. It takes energy to turn water from liquid to vapour so as water evaporates it takes energy from the surface that it’s evaporating from, causing a drop in temperature. Incidentally that effect is present whether or not there is any air movement but the airflow tends to increase the evaporation rate.

If the surface is dry there is no such effect so dry surfaces can’t be taken below ambient air temperature by the wind chill alone.

Nobody can answer that for sure (far too many factors at work) but in my view almost certainly not. Firstly the tank would have to be wet and a 70mph wind would soon dry it off. If it was raining it would be continuously splashed with relatively warm (above freezing) water. Secondly, assuming there was a reasonable amount of water in the tank it would take ages to freeze anyway, far longer than you’re likely to be driving at 70mph and yes, human beings have moisture in the skin so if you were tied to the outside of the van you would experience a real temperature drop.  cold

Woke to a shocking frost here this morning! Unusual along this part of the coast, external temp on Sargent panel read -1.8 & our newly fitted Truma auto dump valve failed to empty the boiler! I would have emptied it manually but the severe frost took me a little by surprise and I've been laid up with a horrendous infection in both lungs since before the P'boro show which has confined me to the warmth of indoors doing very little.

Sorry to hear that CC.  Hope you recover quickly.  This cold spell will last a few days more.
There  was a cold wind at the show when i was there.
About the coldest April i can remember.

I had water in mine, as CC says we also had a real bad frost this morning, did a check and fortunately all is well but drained it down anyway just to be sure, better safe than sorry
