Small heater?

[trapezeartist]

stainless bowl with a pipe in the middle and a fan , £300 lol

good idea , but what a price !!!

What he said! ^^^^^^

Boiling a kettle or cooking a meal (aka warming something up) raises the temperature in the cabin of my boat by several degrees, so the idea of using the cooker is definitely sound. It's just a shame about the price.

The othe snag with any gas-fuelled heater is that you can't get enough gas out of the butane bottle at really low temperatures. This will apply to a Propex heater as well, which is a device that I quite like the look of.

The answer is to switch to propane, which has a much lower boiling point. Propex heaters work on propane or butane.

Can you get propane in 907 bottles?

I think the 907 bottle is only offered by Camping Gaz, who sell butane. But propane is available in similarly-sized bottles, containing 3.9kg.

 

[trapezeartist]

907 is indeed a Camping Gaz product. It contains 2.5 or 2.7 kg of gas IIRC. I think 3.9kg is the next up Calor size, which I have already looked at for my boat. Unfortunately the gas locker has been precisely designed around a 907 bottle, so it looks like I'm stuck with it.

How about the catalytic camping gaz heaters, such as the Campingaz BlueCat Heater, it is small, doesn't cost a lot. Seems to warm the tent fine.. Sure it should do fine in the boat as well

Heating

Am very pleased with the Mr Buddy portable heater, with no probs after six years. Disposable cartridges are easy-peasy but extravagant, so changing the galley supply from butane to propane with a different regulator facilitates use of a 3m hose. Condensation is less than that from the radiant element screwed onto a Camping Gaz cylinder, my former system when celebrating New Years Eve afloat!

right , what if you had somthing like this , kettle full of water , 2 pipes plumbed in to the side, on one of the pipes, 12v pump to pump the water, couple of feet of pipe and at the end a heater matrix and 12v fan .

wee camping gas stove and kettle outside , pipes running down the side of the boat into cabin , stove heats up water , pumps hot water through heater matrix , fan blows how air though cabin , cool water pumped back to kettle , and so on .

aka pc water cooling , well under a hundred quid for parts .

The problem is not heating a small boat, that's easy - the problem is venting combustion products (H20, Co, Co2) while retaining the heat.

jimmcgee and the Pan2000 are addressing the fundamental problem in two different ways.

A plate of ten tealights

ikea sells them for £1 for 100

ten on a plate realy heats a cabin up

I was on the boat at the end of last week

it was a 20 tealight evening

a bulkhead mounted diesel heater. I have a canadian manufactured unit called a SIG100 that runs on red diesel.

Not as convenient as switching on an Eber but. It is very simple and kicks out lots of dry heat and uses no power at all. Great last autumn when I got to the boat and found the batteries flat (another story)

It does need a bunk head and your flue comes through the deck.

Would this work for you?

How much do these units cost Euan? Annoying when they refuse to publish prices!

re cost

£50 second hand from the forum

included full shabang including flue, through deck fitting etc.

some copper pipe and fuel hose, a second hand header tank from ebay, bit of gunk. Full project about £150

probably doesn't help, but i didn't feel i could justify the price of a new set which I think is circa £7-800 for just the heater

try fleabay etc.

stainless bowl with a pipe in the middle and a fan , £300 lol

good idea , but what a price !!!

Just had a look at some prices -

Mikuni MY16 - £1081
Eberspacher D2 - £1360
Webasto 2000ST - £750
Propex HS2000 - £625

Plus all the fitting of trunking/inlet/exhaust/fuel pipes etc.

Suddenly £300 doesn't seem so bad - and it's easy to fit!

PAN 2000 gas/fan heater

Hi. I sail a Sadler 26 out of Shotley and I bought a Pan2000 heater from Percy Andersson in Sweden last year, cost about £300 as I remember. It sits on a ring of the gas cooker with a flex flue through a modified washboard and connected to a 12v battery. It packs away in a small bag in the summer.
Its very effective and makes winter sailing a pleasure - it used to be desperately cold.

I seriously considered buying one of these a couple of years ago and managed to find several very enthusisatic posts on a Scandinavian equivalent of the YBW forum by people who owned them.

Seems a very good idea to me, and being able to pack it away in the summer is a big adavantage on a small boat, but it did seem very expensive for what was in it. Anyway, I never bought one because I was offered an old, but unused, Taylors paraffin heater for under £200 so that was too good to miss.
