Hi it’s not a sealed system it has a vented expansion tank so shouldn’t be to bad it’s all copper pipes by the fire so I am sure moving the pump will cure my problem

Was just going to just have the pump running for the time the fire is on so hopefully no cold shock and I understand the problems with pumps not working so will put an override on the eberspacher pump so if I ever have a problem I can turn that pump on separately from the eberspacher heater just till I can put fire out

We have connected it to the end of the radiator circuit the pipes have to go down to the floor to go round the boat I am going to fit a couple of pumps so I have a back up pump we have only just fitted the back boiler Both systems will have pumps and I can wire it up so one pump works and the other one I can be switched on as a safety thing if one packs up

Hi all I have a diesel heater eberspacher fitted in engine bay and would like to connect the back boiler to the system it has a expansion tank at the back should I fit a 12 volt pump to the rear and put a bleed valve on the stove outlet would the expansion tank be ok at the rear the back boiler stove is fitted at the front Narrowboat is 46 ft long with 4 radiators any help appreciated many thanks
