My heater, this is not pressurised, started tripping after I bled the rads, and failed to top up the header tank. I would not run for long, before stopping and then restarting. I pulled a water hose back from the heater, let some water out, and then refitted the hose quickly, and all was ok after that. it is getting a bit ‘nippy’ out now so good luck with this.

Check the header tank level, and for air in the system, it mat be tripping out on overheat.

Thanks for the reply, on line the Webasto interface is running at £400, not the outlay I was planning on for a look inside my Webasto. I guess this is a USB to RS 232 / 485 converter, is this correct? Thanks again

Webasto Thermotop C, a PC diagnostics programme is available. There are many interface modules available, can anyone recommend one?

That is the best option for me. Thankyou

I could fit steps to the rear, but skipping up a ladder from the inside, with the side rails to hold onto whilst on the way up feels better and easier.

I am looking for a ladder to rest against the sliding hatch, in the open position. With feet resting on the decking which covers the engine bay. This will give quick access to the roof of the boat for single handed operation. Fast securing points are not available without reworking the wood lining.

No bulkhead to fix to, but look a neat solution, thanks for the response.

I am looking for a short ladder to reach from the ‘flight deck’ of my trad narrowboat to the top of the sliding hatch. It would need to be narrow, ideally 200mm wide. I would be grateful for any suggestions.

My intentions were to enquire about a safe method of operation, and try to obtain some experience from people who know about these things; clearly the noise is an issue which I can ‘eliminate’ I know how to do this The trend of the conversation is getting a bit difficult, so think best to close this ‘thread’ now. Thankyou.

Running the main engine for hours is not recommended, moored up for a couple of days needs some ready power. Solar is ok when the sun shines. Petrol on a boat is not good. 12 Volt would have lower losses, and would connect directly to the DC Bus, but supplying a useful current would make it a heavy thing. So, a 2kva unit, 230V 1 ph, on LPG plugged into the gas supply, seems about right, but I have not been a ‘boater’ for long, and I have a lot to get up to speed with..

Thanks for this, I am looking for a feasible and predictable power source, 2kva Honda from LPG seems to be right. Excluding solar, petrol, and running the main engine that is. The ideal would be a 12Volt LPG generator, 4 stroke, yes secured to the bank with a large picketing screw, the noise 70/80db, I can deal with. Thanks again for the response, if a 12 Volt device is available, this would be good to know about. Thinking on though, this would mean the generator is a bit of a lump, and I nee something light and portable....

Standby LPG generator, 2kva, sat on the bank, off the boat that is; to run this from the gas supply in the gas locker. What do I have to be aware of to make a safe installation?

This is the Engine from Firefly, a 2 cylinder Mamod style, to the right is the boiler, looking aft in the attached pic. Complete with four solar panels on the roof, and steam pressure gauges to drive by. Advanced stuff for 25 years ago.. Steam4.pdf Steam3.pdf

Just found thie pic of the Firefly Engine Steam3.pdfSteam3.pdf Steam4.pdf

Looking back this should have been 30 years ago, went through Crick, this was out first boat hire. The pre hire interview was pretty stringent, but we had a good week. Maintaining steam pressure, was a technique to master, and you may be right about the engine power.

Firefly, memories now, we hired this steam boat for a week. Mamod style two cylinder to a very large prop, the boiler was to the left of the steering position. Each morning the water level sensor had to be cleaned of oily deposits, spit cocks to the cylinders opened, and with a bit of pressure, open the throttle and then close spit cocks on each cylinder to get the motor turning, this clear’d the water from the cylinders. Imperative, stay in the canal centre in the deep part, and if passing an oncoming boat stay in the centre till the last minute. The engine came from a builder in London, at Kew, i believe at best it provided about 7.5kW of power, and apart from a bit of hissing, was quiet, easy creeping upon the ducks on the canal. Is this boat still about??

Taking good notice of the comment, I now have a system with three 2 port valves, a pressure vessel, and some logic is now required to ensure the Webasto is shut down, isolated after a time delay, and the engine connected to the radiators via the two ‘two port’ valves. A monitor for engine temperature would be useful to reverse the operation should the heat load be excessive. As is the way, thought this would be a simple modification, work in progress, thankyou for the advice. ~ Tractor ~

Relay, just a remote switch operated by a coil. Energise the coil, which is an electromagnet, with say 12 Volts, this ‘pulls’ the contact of the switch together to make the circuit for the electrical supply to something, heate light etc. The relay permits a light signal, to the coil with low current, to switch a high current, like the starter motor on the engine with hundreds of amperes.

Thanks for the help with this. My pipe work is all plastic, 15mm I am guessing, so an adaptor, metric to imperial is available, ‘dccruiser’. The boat has a Webasto for calorifier and radiators which works fine, but I am planning to use a valve to divert hot, engine water, to the radiators. The 12 Volt vale recommended looks ideal ‘MoominPapa’, this appears to have limit switches to remove the supply at limit of travel, and comment from Blackrose is a good prompt to make sure I get the right ‘porting’ arrangement? This is all preliminary stuff, so come the new year I will get the job done.... Thoughts, my plastic pipe is Grey with hand tight fittings, is it possible to ‘clamp’ this stuff whilst cutting the pipe to insert the valve? The thought of draining the contents and antifreeze, will make the job a bit messy. Also I guess I need to watch engine temp. Beta 43, to make sure it is still running at the right temperature. Thanks for the help with this, I will keep you posted on the result .... Tractor

Thank you, looks like what I need. Tracror

I am trying to locate a 3 port valve to operate from 12 Volts, 15mm connections preferred. Required to divert engine hot water from calorifier to radiators. Thanks
