How much gas do you use?

Easily sorted. Get yourself a 500 litre Calor vessel installed on your boat then you can buy it in bulk for 42p/litre for the boat too. 

Or have you now spotted the reason for the price difference?

 

I was wondering if anyone spotted the poor comparison?

Propane has a density of 0.49 giving a price of 42p/litre the same as 86p/kg

Still around 1/2 the price of propane in a cylinder!

It's the boiling point that is of interest - which for Butane is -0.5degC. While propane boiling point is  at -42degC. 

if its below its boiling point there will be no gas boiling off the liquid.

I have known campingaz  to fail to light in frosty weather.

I have been known to place small gas cylinders in warm water to make a flame a little more energetic!

The best price comparison would be the price per KwHr of energy rather than price per kg weight.

If my calculation is correct my campingaz works out at around £1 per kWh which backs up the thought it is somewhat over priced (even when the small quantity purchased is factored in).

Can it be used solely for heating a tank of water by isolating the rads & using a timer to run for ... i dunno ... one hour to make enough for a shower & washing up / laundry ?

I currently have an eber and use it for one hour to make a tank of hot water and im looking to assess whether an Alde can be economical on a liveaboard boat but for hot water not central heating . 

A boat im considering as a replacement for my current boat has only an alde & installing an eber is not affordable . 

If an Alde is just plain uneconomical for hot water only tjen the boats a no goer so im trying to establish how much gas i t might use 

cheers

My Alde takes about 50 minutes to heat my 22 litre tank up to shower temperature which gives me enough hot water for a shower and wash up.  In the winter the back boiler warms the water in the tank and it only takes 15 minutes to get it shower hot.

A 13kg cyclinder has a nominal 180kWh of energy, which at £25 will cost around 14p/kWh

A litre of diesel is about 10kWh, so is a cheaper fuel.

Blimey if you own a boat where else would you live? I can understand people also owning houses, we owned them for years in places like Cornwall for weekends away and holidays but no way to live in what a crap idea.

We use about 13Kg every 8 weeks, full time liveaboard. As an added bonus we've just got a repalcement bottle at Castleford for £18, cheapest we have found anywhere (even beats that place at Stoke on Trent!):D

Have not read the whole thread. So this may have been said before. We too found the place in Castleford. Cheapest we have found. I believe they top up their own bottles. Hence the price. We had absolutely no issues with the gas.

I would say yes that's entirely feasible, if it is already installed then no point changing it. Going on my figures if you run it for a hour a day just heating hot water then worst case scenario is 3 weeks per cylinder, could possibly be 4 or 5 weeks if not using central heating. 

I have heard that alde are better when they are run regularly so an hour a day should be good for it. 

If you want to heat hot water in summer high temperatures then It is best to bypass the thermostat, can't remember how that done but it quite simple someone on here will probably know. 

If you ever need it servicing then this gentleman comes highly recommended

since starting as a solo liveaboard in march I haven't yet got through 13kg. Although I just use it to cook and boil the kettle for hot water when the engine has been off:D

13Kg usually get 3-4 months from it.  This runs cooker and water heater.  Cooker used daily, shower used daily.

The comments about the silly costs from Camping Gaz - why don't you change to Calor, then it's just expensive instead of total rip-off! If space is really at a premium the little 4.5kg calor bottles are still available but do cost more per kg than the bigger sizes, but still cheaper than Camping Gaz. I know you can get adaptors to convert the bottle connectors as I've got one!

The gas locker on my boat is made specifically to suit the 907 campingaz cylinders . Even they are a snug fit.

I think modification of the gas locker is not a sensible  option.

That's the same as us, liveaboards with ordinary house size cooker, used for kettle and daily cooking usually from scratch, we like to eat well :D

Same for us, cook and bake, live well and both love cooking. Only difference is I only pay Calor Direct £25-73 including delivery

We use 3-4 13kg bottles per year, full time live aboard, the wife does quite a lot of baking. Also some times we boil a kettle up to have a wash if we have not been running engine or heater.

Solo liveaboard, 13kg for gas hob and oven lasts me about 5 months. 

I'm with Rumsky on this one. I've been waiting for my first 13kg bottle to run out, and it just has. 5 months just using oven/grill/hob, solo with visitors sometimes and a roast about every other week, 20/3/40 mins oven most nites, the odd bit of grilling and two teas a day. It's certainly set an excellent precedent, though I was prolly being a tad frugal at times. If I use enthusiastically I should always get a good 3+ months by the look of things, so I'm delighted. Unlike water and leccy :(

I had a nasty accident changing the bottle over though - just nipping up the nut with the little spanner the gas man left me, it slipped off and I managed to tear a lump of finger off on the blunt/rounded neck of the bottle. I'm always careful using grinder/drills/planers etc, who would have thought one could do so much damage out of nothing :(
