Anybody know anything about getting an 1800 Wasllas parafin heater to start after long summers

Is the unit running up but not firing?
First check that the fuel is getting up the line (lift the tank up to heater level) if it is one of the moveable plastic ones) to make it easier?
Is the pump clicking - if not... new pump
Is the unit drawing current - if not check the fuses on the pcb behind the covers, a bit of a ******* to get to unless you unmount the unit
If it is drawing current but does not go to about 3 or 4 AMPs during start up then maybe the igniter(glow plug) - not too hard to replace
Other possibility is that the thermistor has failed -
All else fails talk to the importers Kuranda who I have found very helpful

The instruction manual, p2, suggests that if the unit doesn't start after a long period of non-use, try lifting the tank above the heater level and going through the start cycle with it in that position.

Unfortunately , Done all that . Contacted Kurunda and they suggested removing filter . Will try next time I am on the boat

How long have you tried starting for?
I left mine unused for a long time (6 months). On restarting I thought it was kna....broken, on shining a torch through the translucent delivery tube I could see the paraffin moving along...it took nearly 20 mins with the reservoir raised above the burner.
Also, I have found mine very sensitive to supply voltage...things went a lot better with the engine running, however that could be more of a reflection on my batteries & electrics.

Absolutely! This exactly what I experienced with my 1800. It also pays to switch it off after about ten minutes of pumping. I then find it starts more quickly thereafter.
I put up with this post 'over-winter' problem for a couple
of years before realising that the simplest thing was to start it every couple of weeks during the lay-up.
No problems since though low voltage IS a problem. It draws 5 amps on 'start', so either having the engine running or a battery charger on is really a big advantage.

My boat came with an 1800B of 1970's vintage, that was a pig to start unless, as you say, the battery was on charge. I was lucky enough to get a more recent, 1985'ish, 1800S. This is of rather different design, still current, and I'm very pleased with what was a fairly straightforward swap. Battery voltage doesn't seem to be an issue, despite lengthy wire runs and it started OK last w/end after about 3 months idle. After start-up, it uses very little amps, which pleases me.
PS:- servicing the burner might help poor starting, they can coke up AFAIK.

Hi
Years ago there were lots of various types of paraffin heaters on market . The type that I remember was a Dome of mesh with a wick in a groove the bottom of the wick was immersed allowing it to draw paraffin up.
You controled the output by raising and lowering the wick.
Could someone tell me what paraffin is called in eastern med and how does it differ from diesel.
cheers bobt

I had one of those in by boat until three years ago. One frequent problem after a long period of rest is that the fuel pump does not start, due to corroded pump contacts. You could try to overcome this by gently tapping the fuelpump body. If no result, you must clean the contact surface. Easy job, done in 15 minutes.
You will know if the pump works or not, as it has a very distinctive sound with a "click" every 5th second or so.
Good luck!
