How can I run my shower without electric or the engine please

I have purchased a houseboat which has no engine and no coal burner, can anyone help me to find a way to run a shower as the electrics on the bank are only 16 amp and I believe I would need 32 amps. I am also on a tight budget. Thank you in advance

Diesel additive

We get our new boat delivered in few days and I'll need to fill up with diesel for the first time. Should I use a fuel additive from the start, and on a regular basis, to inhibit the diesel bug and help precipitate any moisture? I'm having a Fuel Guard filter system fitted for added protection.
Thank you

Exhaust lagging

I would like to ask if it would be a good idea for me to lag the hospital silencer in my engine bay? If so are there alternatives to the lagging that is mostly sold for exhausts as it appears to be quite narrow and would take a lot and is expensive. I was wondering about domestic regular hot water lagging?
Thanks

Gettin Goin

I'm a 25 year old fella. I was born on boats and lives on the canals for most of my life. It's something that I have decided I cannot do without. However, with section 8's being a thing of the past. No mortgages for narrowboats unless you want ridiculous interest rate and frankly not having £15,000 laying about. What can I do? I'm not after much, just a 32ft plus springer with a running inboard diesel, hull in decent nic and a bsc!
Any advice?

Victron energy monitor fault

I've using a Victron 600s monitor to monitor my 5 leisure batteries. It's stopped working properly. It says Boot 1.01 or it flashes quickly and says nothing at all until I turn the engine on. At that point it appears to work ok but it only shows 1 amp going in to the batteries! As soon as I switch the engine off, the monitor starts flashes no and displaying 600s and that's it. Now I happen to have a second LED display for the monitor. I swapped that and that one does exactly the same thing, so it isn't that that's faulty could it be the shunt? Or something else?

Accumulator and expansion tanks

I bought these as advised by the people I bought the calorifier off but the guy who put it in said I wouldn't need either of them so didn't plumb them in. I think I want to have them in really so am planning to install them myself. Am I right in thinking the accumulator needs to be after the pump as in water tank,pump,then accumulator.......and the the expansion tank at other end of boat : calorifier the expansion tank before pipe work?

Drilling holes in the superstructure, what are the requirements?

I want to fit some navigation lights to my narrowboat. This requires me to drill some holes in the steel superstructure, both for wiring and for screws to attach the lights. Are there any special precautions I should take to avoid these holes becoming rust points, and are there any other areas I need to bear in mind?

yanmar air filters

hello again. i have recently bought a yanmar air filter, the one recommended in the manual of my barrus shire 1200 engine fitted to my 46ft narrowboat, the filter number is 119808 12520. i found one on ebay sold by a company called Farol who tend to mostly sell agricultural bits and bobs, the add read 'genuine yanmar air filter' .
so anyway on the add picture it looked exactly the same as the one that i am using right now yet on arrival it was too long and too large , it was hard to judge in the advert as they look the same , it seems i have it's bigger wider brother. the filter i have has no name or number enscribed on it and it has all confused me, any thoughts would be very gratefully accepted
