Question Coolingwater out/inlets on BMC-engine

Hi, I am living aboard in a very cold climate (Northern Scandinavia) and urgently need to further “warm up” my accommodation. My plan is to complete my diesel heater (with water system) with use of the heat from my engines cooling water witch I am prepared to start some very cold periods. I know how, from drawings and recommendations, how to manufacture and connect the system. But I don’t know WHERE on the engine I shall adapt the outlet and inlet to the engines cooling water-system, from where I must connect to a “heat transformer”. My engine is a 6 cyl BMC Tempest Sealord from 1976, aprox 85-90Kw (100- hp). Anyone who knows a with info?
Thanks in advance.

I'm not familiar with that engine, but there should be a 16 mm or 19mm outlet coming off of the engines fresh water pump some where (maybe capped off).

And then another one on the engine head or intake manifold for return water.

P.S. Your link is not complete.

Hope that helps!.............................._/)

I have been doing some tests between a flower pot over the top burner on the stove, an Origo heater using methyl hydrate, a small 120V oil filled heater.
That is about the order of heat produced. If you have an inverter the oil filled heater draws about 500 watts at full setting and less at lower settings. Could be you could run the engine while usinmg the inverter to power the oil filled heater.
You could have heat real soon with out any modifications.
I run the heater off my 1000 watt Honda generator. The generator is $1000- Canadian and very quiet. If you put the generator about twenty feet or more away you will not hear it on a normal day.
