Running Wet Webasto Overnight in Corsa B 1.5 TD: Battery Requirements, Fuel Consumption & Models

Question

Hello, I have this question. I would like to install a webasto parking heater in my car. I was thinking about wet webasto, because from what I heard it consumes similar amounts of fuel and there is no need to install air supply pipes, and I have a small car (Corsa B 1.5 TD). This is where my...

The wet webasto heats the coolant, if you would like to have heat inside, you still have to turn on the fan, and this consumes a lot more electricity. Tell me, what devilish idea did you come up with with this heating, what do you expect?

Why stay all night long. You program the controller 10 - 20 minutes before the ride, and you have a warm engine and interior.

Maybe he is moving out of the house in favor of the car I think an ordinary battery may not be able to take it.

Do you live in the car?

I go fishing more than once and I have slept in the car more than once. You do not know how much more or less such a fan pulls in the lowest gear? It doesn't make sense at the higher level, because it's too loud.

My calculations show that if the webasto pulls, for example, 45 watts, it will be about 4 amps at 12 volts. 8 hours and we have 32 ampere hours. If the battery has 72 Ah, it should be ok ...

I could never understand anglers ...

For example: And to read a bit, when you enter webasto power consumption in the google. But you have to count 2A. This is a lot for long-term consumption.

Przemo9826 · Answer

These 72Ah are the absolute minimum, but so that I could sleep well, I would put another battery and cables in the trunk to fire the car in an emergency.

Haha, Przemo9826 I don't understand some things either, but never mind

I edited the post above: "My calculations show that if the webasto pulls, for example, 45 watts, it will be about 4 amps at 12 V. 8 hours and we have 32 ampere hours. If the battery has 72 Ah then it should be ok ..." I will add that I saw such powers on stoves with built-in pumps ... If I'm wrong, make me wrong. Oh, and thanks for these topics. I couldn't find them ...

Edit: Przemo9826 also thought about the second battery and I do not exclude it.

Przemo9826 · Answer

Are you going fishing? Do you sleep 8 hours in the car? :D

You count the stove itself, add the fan, I hope that it will also pull with 5A, without it you will only have the liquid heated.

And this battery must have the minimum 72Ah, not only on the sticker ...

A party worth these fish? The stove costs its own, a new battery of such capacity too ...

zbyszek_k007 · Answer

Well, this is how much sleep takes on average. If you look for it well, you can buy a stove with all the junk for about 1000 PLN. "The maximum power consumption is 34 watts (slightly more than the two blinker bulbs), correspondingly less in the lower gears." a quote from

https://www.elektroda.pl/rtvforum/topic1169538.html

The whole thing will definitely not exceed 5 A (unless at start-up). In addition, from what I know, when the stove heats up and works half-heartedly, the power drops by another 10 W ...

Błażej · Answer

But this result was given for the dry webast which heats the cabin air. You want wet, that is, you still get a fan in the car, even in the lowest gear, and a fluid circulation pump. And that's a lot more electricity.

zbyszek_k007 · Answer

The furnace itself, used as a 5 kW auxiliary heater, draws 26 W. Webasto Termo Top C has 5 kW of heating power and consumes 40 W (it has an integrated liquid and fuel pump). And the blower should be added to 40 W, and in the lowest gear I hope that it will be about 10 W. During operation, everything will consume a maximum of 5 A.

And all this in a small chest, and somewhere to fish

Przemo9826 · Answer

How is it where? In the water.

T5 · Answer

To sleep, buy dry. There is no point in heating the engine block - heat loss. In addition, a second battery in the trunk with a relay disconnecting charging. It will be warm and the car will start.
Go ahead

How is it where? In the water.

Take a spinning rod in your hand and go hunting. And you'll see that a cool thing like a little 60 is fighting.
