In the background is the water and dieseltank, 200 liters each, and two on each side of engineroom. Total 400l each.
To the left is the gigantic diesel heater. 8000 watts. Water system. This is an amazingly simple heater. It's sensitive from draft, meaning it has to get the burning oxygen from outside as you normally get an low pressure inside a boat - then the smoke doesn't go out - it goes into the boat :-(. It's possible to fire it with small wood but a bit hard to get the ash out.
As we need the space and don't like the somewhat smelly, messy and very hot metal heater inside the boat, we will install an modern German Eberspächer DW10 heater inside the engine room. It will be very silent and safe.
This is the two sea water inlets from each side of the keel. It's possible to clean one at the time as the pipe ends above waterline.
In the keel there is three GRP tanks for diesel total 180 liters. Unfortunally they dosn't have any internal connections to each other, so it would be a complex mess of valves and tubes or pumps to be able to use these tanks. The two in the front will not be used as the black- and greywatertanks will be installed above them. Each of these tanks will be around 180 liters. And they will have two pumps of the same brand for the possibility to change them. In emergency they could be used as bilge pumps.
