Brain picking time. I have webasto heating on new boat. It works but it sort of whoomphs the whole time. I notice other people's have a constant roar. Any ideas what may be wrong with mine?

Our noise varies from a roooarrrr.. to a whoomph to a dronnnnne but one thing DOES remain constant and that's the amount of elecrtricety it uses - WAY more than the manual would suggest me thinks!
On the plus side - it IS handy to have set to come on before getting up on a morning to a) give us hot water and b) take the edge off the boat before I make the fire up .

Tried it again and it's fine now, I like things that mend themselves. 👍

Other than that, ours is fine. I tend to feed a bottle of redex through it occasionally, which tends to keep the carbon crap at bay. Also bleed the radiators if it's not been run through the summer, though a better option is to run it on one radiator once a week during the summer months. |

It could be the sensor 'eye' that needs cleaning / replacing. This was the case with my old bus (Nov 2013 - Mar 2016) - eye was cleaned (and then worked) but second time it 'failed' it was replaced.

I think nail on head with batteries despite being plugged into a mains charger. When it works it's daytime, when it misbehaves it's night with lights on and I do know the batteries are foobarred, it's on the list. The lights dim as it tries to fire up - a bit of a giveaway! |

Fire your engine up to start it, and once going, just switch the engine off. It will run like that for about an hour and a half.

You'd think a 120a charger would do it, but I guess it's just ticking over. Also figure the more I try and fail to start it the more coked up the glow plug will get so I'll replace the knackered batteries and see what happens. It's a minor issue compared to the month of interior manoeuvring I've nearly finished. Easy question. What benefit is a bank of 4x 135ah batteries other than feeding an inverter? I'm generally (always) plugged in the mains so don't need the inverter. I'm planning on weighing in the batteries and just getting two instead. Any problem I'm missing? Old boat managed fine on 1x 10 year old 200ah but the heating in new one seems to want some welly to start it up. |

Just make sure the wire from the regulator is man enough. |

Something like this with variable voltage. Has to be 30 amp though, as I seem to remember the webasto takes 25amps on fire up.  |

Shame it's other end to the bow thruster battery or I'd hook it up to that which doesn't get much use - none in fact, it's in the kitchen. |
