Inverter

Hi. Today I turned off my inverter for a sec and I heard water gushing out underneath. Is this normal and is there anything I need to do before heating or running water again. About 10 litres came out in total, think it just stopped when the system was empty. Was this water from the heating system does anyone know.

Thanks for reply. Yes think the system is totally empty. Where do I reset it

Ok will check it out tomorrow, just want to make sure it’s filled back up with water before I turn it on, I take it once I turn on the water pump it refills

You lost power to the automatic frost protection valve, this valve is kept closed by an electromagnet arrangement which allows the valve to drop open when the ambient temperature drops in order to prevent the boiler from freezing, BUT will also drop open if the power which holds it closed is lost. It has to be reset manually AFTER power has been restored. If the ambient temperature is below the threshold the valve will only hold closed while the boiler is turned on.

The power source is the leisure battery (the habitation 12v system). If the leisure battery is absent AND there is no power coming from the charger/transformer (as in if there is no ehu or the charger/transformer is turned off) the 12v habitation system will be 'dead' and there will be no power to hold the valve closed and it will drop open.
If the leisure battery is present and in a decent state of charge that alone should hold the valve closed and having no EHU or the charger/transformer turned off should not matter.

Am I correct in thinking when you say 'inverter' you mean the charger/transformer, as an inverter would have nothing to do with the power supply to hold the frost protection valve.

Theres several different

They do not drop open if the heating is turned on no matter how cold it gets outside.
While heading to Spain in January 2017 it was so cold in France that one morning we found an icicle had formed from the flue vent to the ground. The moisture in the flue gasses had condensed and frozen as it had been about -8°C outside.

BTW, a good reason to use Propane.

Mine has no electrical function, It must be just a mechanical thermoswitch.

I wouldn't fancy having had that type two years ago , I would have had no hot water for my morning shower,

A slightly different type of 12 volt plug but the same principle of a fuse fitted inside the tip.

Lads thanks a million for all the info. Have to say ye are definitely a mind of information. I will try all over the next few days. That’s if I don’t end up in the big house I’m almost gone around the bend, spending everyday in the shed till this time of the night putting camper right. Replaced beams in floor of gas locker, and side wall beams, now have back bumper pulled off and am replacing part of back beam. When one comes in after getting hardship all day it’s great to sit down and read all the replies, Thanks a million appreciated

Yes looking forward to that Thorn. Ya must look up that waxoyl, now it’s not bad the gas locker was the only really bad bit, and a slight bit at back two corners then I’m hoping that’s it all sorted. I will run all around top to bottom then and seal everywhere, when at home it will be always in the shed so should stay sound.
