Broom 39 calorifier..

[ralf2]

..ive a problem with the hot water system on our broom 39kl 2006 model,the water seems to cool quite quickly over an hour or two no matter how long the engine has been running,this is also the same when the immersion is in use.
Just wondering if there are any other broom owners with similiar problems or anyone with some advice please.

Airlock?

Try a descale. It could be half full of calcium deposit, so not much actual water inside?

Not a Broom but....
Does it get piping hot in the first place ?
Are the isolating valve(s) on the engine fully open ?
My tank will normally stay hot for around 12 hours overnight ,however if you use any of the water after you stop the engine at the end of the day,cold water mixes with the remaining hot and a very tepid flow only is available in the morning.
My trick having drained down calorfier for any reason is to use fresh water hose held against inlet hose.Only open at at very low pressure to force all air from system.This does dilute your engine antifreeze a tad,but you can add neat stuff later to compensate.

Identical thread elsewhere yesterday, thermosyphon is the likeliest answer, calorifier heating engine. Solution is to fit a non-return valve or else a longer engine to calorifier feed pipe to the top calorifier connection and put a long loop in it.
