Post Subject: calorifiersI have a 35 n/boat powered by vetus 3.05 engine.Have fitted a calorifier also installed an accumulator in the cold feed line, my water pump is rated at 2.2 bar, the accumulator is preset to 1.50bar I also installed a new prv rated at 3.0 bar.but unless i turn pump off and open a hot tap after approx 2hrs of cruising the prv lifts and releases water into the bilge, is this normal or am I missing something?
