We have recently purchased our first boat and collected it yesterday, the boats previous keeper had sold it due to ill health so we have only had the benefit of a handover from a brokerage with a point out as its its fittings,
we were told the BMC runs the calorifier as does the boatman stove.
The system has a run along both sides of the boat and feeds a small radiator in the bedroom, we were told this had been turned off due to a leak on it.
we cruised about 5 hours towards our moorings and had hot water from the tap, we fired up the stove whilst still running and after inspection of the road all looked good, my dad turned on the rad and we started to get a flow that was extending down towards the stove at the front and no leaks.
i then started to get a back feed through the header in the engine room.
once the rad was closed off this stopped again.
is that due to a crossover in the systems running together?
is that an air bleed issue?
ive been looking around for an answer and note the mention of antifreeze? Is that a standard motor antifreeze?
