Condensation

Ricko · 2021-01-10 20:03:04

Hi, is it just me but I seem to have a ridiculous amount of condensation inside the roof in the back.
Normal?
Cold outside, slightly warmer inside causing it??
Cheers

Yes and wet heat like gas. Ventilation or stop breathing as much. I covered mine in bubble foil and managed to get a taxi roof liner and cant say i had a condensation problem. There was two sleeping in the van and a large dog.

You will never stop it all but ventilation is the the best defence.

Not nice letting warmth out when you are sat in on a night but anytime during the day, vent as much as possible. If you are driving, have the heater and blower on full and open a couple of windows an inch or so. A good idea to open cupboards too to let them air out.

As Casper says, breathing and burning gas causes a lot and we also bring a lot of moisture in via wet clothes, boots, dogs, etc. With little or no ventilation this just builds up. I get a lot less condensation nowadays that I am less active and am not out getting soaked all day.

Covering cold metal surfaces hides obvious signs of it to a great extent, but the moisture is still there and will make fabrics damp and musty.

Condensation has been no problem at all for me this year as I have been glamping on hookup all winter and can ventilate as much as needed and still keep warm.

I am waiting on better fuel line then this is going in my convoy.

Agreed with all this, and I haven't had any issues. That I've noticed neutral

I keep debating whether to swap my Propex for a diesel heater. On the one hand, the fan can be adjusted and uses less leccy, but that glow plug has a pretty hefty draw.

I ordered the 2kw one. Hope its taking less draw but we will never have it on high anyway. Its more for taking the chill away and never used when sleeping or even coming on a timer. I do have the added advantage of having the room for a bank of batteries rather than the one 110ah like my last van.

EDIT.

I was told 10amp on start up and 2amp when running is the norm. You are around 30 seconds to fire into life.

This is the part I can't work out the answer to. Does that 10A only happen when it's starting from cold? If I turn it off, and turn it back on 5, 15, 30, 60 minutes later, does it use the glow plug again?

If this is something you could answer I'd be much appreciative

I have asked on the facebook page i am admin on as we do have the odd clever bugger however if you use Facebook there is a dedicated page for them

@kenbw2

Looks not. Full 10mp each time. Even if still hot/warm it will still use the glow plug for the same amount of time. This was from a bloke who runs a 5kw on in his workshop for the past 5 years and another on his boat however if you are thinking of switching due to running cost he thinks the propex was more expensive to run at 13kg of gas every 7 days. Probably uses less energy leaving the diesel on on at the lowest setting 20amp would give you 5 hours or less if the 10x2amp is exact. I was watching a youtube video of a bloke working out the mpg. This is a screen shot of the results. He just never said if it was a 5 or 2kw

The dose is what the pump pushed through each cycle. Pulse is your temp setting as the pump is pumping more then x 60 seconds and x 60 minutes to give the hour.

Ill leave you to work out the maths if its cheaper to run than what you have

I have heard that there is no difference between the 2kw and 5kw ones. Sometimes from people who have stripped both types down.

Anyone know if this is just rogue suppliers, or has anyone found any specific differences?

I am wondering if it's a case of being cheaper to just make one model and detune some via the electronics or fuel feed.

It is a pity that the glow plug isn't a bit smarter. In a small van the starting cycle is likely to be constantly triggered by the thermostat trying to maintain a steady temperature.

Omg thank you for relaying that to me, I've been trying to find the answer to that for months! But yea that settles it, very likely that the Propex is kinder on my battery.

For comparison, the Propex uses just under 2A while it's running, cycling on and off with the thermostat.

Running cost is definitely a factor, but a bigger benefit to diesel heater is being able to more easily refuel than Calor. It's a pain trying to get a new bottle every week.

But unfortunately my battery is my most limited resource, so I suppose I'll stick with Propex.
