We have a N20 that we overnight in occasionally, however on those chilly nights and mornings I am considering a method of heating the cabin up.
I have read up on those small portable gas heaters that you can buy from outdoor shops but the issues with condensation and Co2's has put me off the idea.
Has anyone got any suggestions for a simple way to heat the cabin without risking our health ?
Thanks |

Put the cooker on???
Any open flame will generate condensation..... any poor burning flame will generate CO. A properly adjusted flame is fine.
This is the holy grail of small boats.... an inexpensive heater that generates no condensation and is absolutely CO safe.... when you find it, let me know.... there are £1000's to be made.
Your options are limited and generally expensive.
Catalytic heater. Used to be very popular.... can technically produce CO, but not generally a problem.... get a CO alarm anyway. They run on gas and kick out a lot of heat.... and some condensation. They need a vertical surface to mount on.
Propex... gas powered hot air heater..... a couple of hundred pounds and a bit of DIY gets you condensation free warm air. Absolutely no chance of CO as room sealed. Can be heavy on gas, so no good for living aboard or cruising the arctic circle. Needs electric for the fan.
Eberspacher/Webasto... diesel powered versions of the Propex. All the benefits, but need diesel to fuel but cheap to run. Secondhand.... £400 plus some DIY. There are some crappy ones about.... from £900 new.
or...
Put a jumper on and an extra pair of socks!!!!

Hi we usually put the hob on for a few mins and that warms it up a treat. a small portable gas heater would be fine as long as all your vents are clearquote:

Just back to base from a trip to Ripon via Selby and York. 135 nautical miles with a bit on the ouze in flood. A few boats ie Narrow and grp had been waiting at Selby for 4 days to be let loose to York, and the same at Naburn coming south. We got out on our booked day in Jacob the norman 27. The old norman did me proud and and outran the coffins after coming out of Selby on the 3rd pen. Point being the weather was cold morning and night but before going I fitted a Propex heater alongside a lpg cooker and rinnai heater which was already fitted. Beautiful, just like a combi in the house. 9 nights later after daily hot washes plenty of cooked meals and programmed hot air I reckon 1kg left out of a 6 kg propane bottle. No brainer to me.

Mobile gas heater, dangerous, cooker dangerous. How many people have died using these methods of heating. Neither of them are designed to heat a boat.
Eberspacher or webasto air heaters but make sure you go for the marine version |

Are you saying that a boat cooker knows you are not cooking so it kills you??????
No gas appliance is any more dangerous than any other as long as it is properly maintained and used within manufacturers recommendations.
Although each one is tragic, thankfully deaths due to CO poisoning are rare.

Seems like there are variations of opinion and I thank everyone for their input.
In my case it is simply a day boat that we occasionally overnight in.
No more than 2-3 nights in any one cruise.
I have come across 12v car fan heaters that you can just plug in to the cigarette socket (of which I have 2) so maybe this may be a potential solution for me. After all, its just to take the chill away for a couple of hours here and there. I guess they are quite hungry for power so I would have to limit the use.
Has anyone used one of these, if so what make & model ? |

I have 2 of the heaters you mention and use them as demisters when the screen steams up, I have 2 50A alternators and wouldn't even consider running them without the engines running, even then I see the voltage drop down as it's displayed on my chartplotter.
You'd soon have a flat battery on an outboard powered boat with them.

I have tried these screen heaters, i have 2 batteries I use for leisure and one I use to start the engine. I am running a 1500 diesel with high output alternator. When I tried these heaters it was fairly cold, but they didn't have much impact on the temperature. I tried using the excuse of warming a pie up in the oven, this takes the chill off, especially if you have a couple of rounds of toast done under the grill at the same time. If your not careful it piles on the pounds, lol.
I purchased a eberspacher airtronic for £1200 but never got around to fitting it and now the boat is for sale so I cannot really comment on how good the eberspacher really is, but I am told they are very good.

Good morning all
As you know i am doing up my Norman 17 and the heating and electrics are items that i have agonized over and over, However i had an epiphany one day while thinking about how i upgraded a few caravans back a years ago.
things i have taken into consideration are condensation, ventilation and heating, these items in mind the tack i have decided to follow is i will be fitting insulation where i can and also fitting acoustic carpet to the walls and ceiling thus reducing cold surfaces, then i am going to use the very same heating and electrics you would find on a standard modern caravan, including a truma hot waterunit, hot air heating etc.
I see no reason why this equipment cannot be used and should be a straight transfer.
My Point have a look at the caravan industry the equipment is very state of the art these days and very easy to fit. plus it all works on 240V & 12V

Hi Deano
The ventillation on a Norman in standard form is borderline, my 23 having failed low level ventillation until I had door vents fitted at the bottom. It is very easy to put the rings on, the grill on and the oven on all at the same time to keep warm on a cold night. It's easy to jump in bed and think I will turn the cooker off when I am a little warmer. It's easy to fall asleep and leave the cooker on especially when it gets warmer and you are tired and fall asleep. There is only so much oxygen in a poorly ventillated cabin and when you start competing with a cooker there is only one winner.
Being cautious saves lives, people don't think about the silent killer.
The pun about the pie was light hearted, it's just an excuse to the wife to warm a pie up and have a warm at the same time. |

I would make sure that you are still complying with Boat Safety Scheme if you need one..... I'm not sure go the chapter and verse on this one, but I think you will need a marine venting kit.... if such a thing exists...

Agreed Deano however i would imagine that the regulations for a caravan and a boat cannot be too disimilar due to construction and standards, However i will be fitting upgrades to the venting system and they will be of a marine design.

I think the regulations/requirements will be different, because Motorhomes tend to have permanent low-level ventilation vents, whilst with a boat, any heavier-than-air gas/fumes will collect in the bilge.

Yip, caravans have vents in the floors for low level ventilation, bit difficult on a boat, lol.
Like I said the Norman 23 is below BSC standards with only a cooker in. I had to put vents in the bottom of the door to pass my BSC. |
