Heating motorhome

ValDa. your home will be fed by at least 60amp and more likely more than that so cannot compare to a 16amp EHU.

Not  quite,  Lornalou  --  the  60 amp  you  quote  will  be  available  only  at  the  Mains  input  point.  30a  feed  probably  to  the  Cooker  Supply/switch  unit,  then  only  13a  max  on  feeds  to  socket  outlets,  {  they  are  called  13amp  plugs  are  they  not ?  }  so  they  are  very  approximately the  same  as  in  a  'van.

We have never used the built in heater in our van. Find a 2Kw electric fan heater with thermostat adequate and we van all winter. Its surprising how quickly it warms up.

We  must  remember  tho',  Fman,  that  JessR,  the  OP,  has  a  disabled  daughter.  Lacking  knowledge  of  her  age  &  disability  we  don't  know  how  her  mobility  may  be  affected.  What  is  nice  &  warm  to  you  and  a  well padded  me  may  not  be  so  to  others.

P.S.  For  the  OP -->  One  Kilowatt  approximates  to  4  amps  so  a  10  amp  supply  will  cover  2.5  Kilowatts  MAXIMUM

16 amps  supply  equates  to  4 Kilowatts  Maximum

You  must  allow  for  the  other  things  you  use  as  well so  a  1  --  2 kilowatt ( 4 -- 8 amps )  thermostatically  regulated  heater  should  never  cause  your  mains  supply  to  trip  out  by  itself .

Too true ABM, disability can result in poor circulation with the result the disabled person feels the cold far more than those with full mobility.

As fairly new caravanners we maybe went too puritanical, having read advice that 700W heaters were the way not to trip switches. As it is, our little 700W oil-filled heater, which is the only heating in our van,  does a reassuringly great job, and is surprisingly quick at getting going. It's not too heavy either.

A couple of these in the bigger space you have might be worth looking into.

what I was trying to say was that the feed into house is a lot bigger than a EHU to caravan. funny my elec shower is fed by 45amp fuse. its easier to trip the EHU than it is the mains board in a house. I don't know of anybody that totals up what amp is being used in a property but would expect that most with a caravan/motorhome would keep a close eye on what's plugged in and being used.

I have just checked the wiring diagram for our Bailey Pegasus, and the three MCBs

6 amp = charger

10 amp= hot water and heater

16 amp= sockets  which include fridge and microwave ,

That does not take into account air con or other extras that may need mains power 

And as the max site EHU =16 amp

I can see why there is serious discussions going on about EV charging from the site supply in near future

We have never used the built in heater in our van

Why?
