Keeping external water pipes from freezing

[Otter Spotter]

Hi need help, I have some heater pads for my fresh and grey water tanks but apart from foam insulation for pipes, what are the thin wire heaters called for rapping around pipe work to stop them freezing and any ideas where I can get them from. Not an ebayer though
thanks

Pipe trace heating. You can get it from Amazon. Mostly 240 volt so can only be used when on EHU.

How long do you need it?
I've got some new 3m 120w ones, used for freezer room drains. You can have one for the cost of postage ?

Thanks but they need to be 12v as I do not EHU at home.

Your battery won’t last long powering them I am afraid.

Your battery won’t last long powering them I am afraid.

190amh battery with 160w solar panel ?

I am afraid not.

Even with that battery and solar, this time of year the panels won’t give much and anything that heats consumes a lot of power. All you will do is flatten the battery.

120watts is about 10amps. Even with your battery it will be flat in 10 hours.

You don't need to be an expert to know that won't work, heating elements and batteries are never a good mix. Sorry.

Ok fair enough, thanks. I suppose there is nothing that uses less wattage, my understanding of Watts Amps etc is minimal

You need to know that heat means Watts which means Amps.

Its possible that a lower wattage element would do the job but you need to research the market to see if anything exists.

The problem is the design of your motorhome. To use it in the winter without EHU it is essential that water pipes and tanks are kept inside the heated envelope.

Its not viable to use a non winterised van off grid with trace wires and heating pads. You either need hook up or change your van for a more suitable one
