Plumbing. C/H and calorifier

The photos above and below show the pipework of the C/H and calorifier over which the bed will be built.
The back of Kabola boiler in the engine room can be seen through the (large for access and ease of use) gap in the bulkhead.
The vertical grey object is the Bolin circulating pump.
At this stage (whilst commisioning the engine) the engine heat exchange pipes have not been connected to the calorifier but have been bridged with the black rubber hose where they enter the bedroom.
The pipework has been designed and installed with ease of access optimised.
C/H pipes are generally 22mm copper and the domestic supply 15mm Hep2O.

The wider view below shows the small radiator which will be in the bedside wardrobe .
The valve which will shut off the C/H and route the hot water only to the calorifier is just to R of the radiator.

Two more radiators are installed in the saloon and under the tug deck.
Kuranda marine, the supplier of the Kabola boiler have recommended the connection of the rads as shown to the top side of the circuit (rather than bridging from flow to return).
Apparently it warms through just as well as the sytem gets hot. A side effect is that the boxing which we will build over over the pipes can be slimmer. The boxing will have a continuous slot along which heat can escape into the accomodation from the copper pipes.
