Continuing from my post about water. Is it safe to leave the built in heater in the motorhome on low all night? We'll have hot water bottles but I was considering leaving the heater on low. This will be on EHU so will be running on electric not gas. Thanks again
If you have a truma heater that runs on both gas & electricity you will need to check the amperage of the site supply , if it is 6amp or less you need to set the control to the minimum setting of 500 ,1000 for 6/10 amp
2000 for 10-15 amp or higher this is to prevent you blowing the supply post fuses ,having said that it is perfectly ok to simply set the thermostat to whatever temp you require .this may also helphttp://www.practicalcaravan.com/advice/28461-how-to-use-a-truma-caravan-heater
You will be fine on the EHU there.
We normally keep ours on permanently,with a low setting,keeps it toasty warm.
As you say, a good idea to test it before you go though.
Have a great time.
