Heater again

[muchy_]

Some weeks ago I posted a question about my diesel heater that keeps going out. Sometimes after a few seconds and sometimes after a few hours.
Now, HLB was kind enough to let me know that this was the control unit and would cost a small fortune, thanks Now, I was messing around with something else (like you do) and I have discovered that one of the batteries in the bank that the heater runs from is knackered. Do you think that this could be the cause of the problem with the heater. Are they sensitive to varying voltages?

Very much so.
On a hire boat fleet I was once involved with the heaters stopped within less than half an hour after stopping the engine on virtually all the boats.
Normally the engine had to be running to fire up the heater.

Trouble is. On some of the older ones (Mine) They need at least 13 volts to start up. I cant realy run mine unless I've got shore power or the engines are running.

<font color=blue>If the heater runs when the battery is receiving a charge but fails after while when not... then without a doubt... get yourself a new battery. </font color=blue>

Mine did something similar then refused to fire altogether. Was tod that I needed a new heat exchanger all in cost £1000 + . Told them I had no money left and miraculously they were able to effect a repair for £300. I think there is a lot of "smoke and mirrors " with these heaters so double check out everything as you appear to be doing.

As iansimpson says -

they are VERY voltage sensitive but if it fires and works well with shorepower or engines running it may well be the early signs of battery(ies) failing.

Whatever, check the voltages before you spend any dosh on the heater.
