Fresh water heater tank placement

As you are possibly aware I have been gong through, among other things,a re-engine from the D3 110 to the Yanmar JH4 110.The Yan mar dealer here in Phuket has done a great job and we have it installed and purring like a kitten.

The last issue we seem to face is the positioning of the fresh water heater.As we are all aware that Hanse with the D3 as the heater placed directly above the engine.

The Yanmar Engineer and the installation manual says that this is completely wrong and that the heater should be next to or on the same level as the cap where you top up the coolant or had Volvo devised a system to solve this issue.

I am still not really understanding the issue but if there is any one who has done a re engine or indeed has a hanse with the new Yanmar installed I am interested where the water heater is located and if it is above the engine was there any special plumbing done to the system.

My Engineer is highly experienced and he is very concerned about this installation!!

Best regards to all

Agree with Leon.    On our 575 the water heater is under the starboard side floorboards between the engine compartment and the nav station.  The only connection I know of is that the hoses to transfer heat from the engine come from the volvo closed fresh water system to the water heater compartment for exchange inside the heater.   So running the engine will heat the fresh water rather than requiring AC.

It would seem simple to me to simply connect those same hoses to the Yanmar.   

I know you can get into issues with the fuel tanks on lift issues.   I was going to install a dual racor filter on our boat and found that everyplace I could put it had lift issues.   Not heard of lift issues on the water system/boiler.
