Maybe more details would be good. How long are you expecting power failure for? Would you just need heat at night when he's in bed or are you looking to heat an entire room during the day? If it's just at night maybe look at a 12 volt electric blanket, you could use it direct on the battery or you could plug it in via a suitable power supply.

 
OK I’ll play ball, if you have 12V DC available during power failures how about a secondary 12V system in the house.

12V heaters and lamps will be far more economic than an inverter.

If your child is at risk, register with your DNO, they have a duty of care. I’m registered with Western Power as a bad tempered grumpy old sod, if the power goes off for more than a specified time they have to provide a means of heating and light.

 
I think that some have blown this up out of all proportion, there are many many people, elderly and disabled and in fact ordinary people who want to "be prepared".

All I asked, genuinely was for a solution to a power cut, and to those who have offered genuine advice other than silly comments like candles etc.

All I wanted to know is if the power went off in winter for a few hours could I use a car battery from a Diesell (I have 2 from my Renault Scenic that I replace every three years) to run a small heater and lights via an inverter.

This was a genuine question to what I thought was a "professional" forum.

 
First off, Tony is right about registering with the DNO, i forgot about that!! As Tony also says, 12v lighting would be better, and 12v heating too. [If you DO want battery power]

It IS a professional forum, so please bear with it all/us!! Problem is, we have been plagued with "troll" type individuals, so some of us are a bit hasty to jump on people sometimes, and of course, sometimes innocent humour [by us] gets misunderstood..

Please hang about here, and i am sure we will all try to advise as best we can.

Might you not be better off with one of them really quiet generators that you can get?? One of them would run for hours.. It is unlikely that the power will ever go off though.. If it does, it would not be for long. If you WERE registered with the DNO they might even provide a generator for you..

Another problem with batteries, is that, if they are not used all the time, they soon fail.. The batteries would fail much more regularly than the power cuts occured..

Me?? I would have a generator...

john..

 
i am late to this thread but all I can say is to agree with others. If you want an emergency source of heat, then forget batteries, you need to look at LPG gas heaters as already mentioned, of if you have a chimney in your house think seriously about getting a wood burning stove installed.

About 3 winters ago storms and fallen trees brought lots of power lines down, and we were without power for 3 days. The WBS kept us warm, and the portable camping gaz lights provided lighting long after the batteries in my head torch etc had gone flat.
 

 
When i was a child, the nie network around our way was atrocious, we were very rural and also culturally isolated from belfast. The electric would go off every night there was a bit of wind. I have childhood memories of my father going out to the garage to bring the superser into the house. My mother would cook dinner over the single gas ring attached to the bottle and then the bottle would be placed back into the superser to provide heat for us. We also had a supply of candles and and gas lamps to light the house.

Some might laugh and think i'm spoofing but this is the truth.

This continued up until the late 90s when they brought a crew of engineers over from scotland to upgrade the local network.

I can vouch for that, 

Are you my secret brother,??? :eek: :slap

I remember sometime in the mid 90s being without power from 23rd DEC until 4th or 5th Jan, I was middle of nowhere and last house in the line, 

@rapparee do you remember The Ponderosa, up Glenshane pass, with the diesel Genny out back,?

When I moved to Northumberland when I was a lad , we moved in with my granny . The house had no electricity or water.

 The toilet was an outside tandem dry midden . The water was an outside cowtail pump that had to be primed up from an underground water supply.

 Character building lol.

 All the equipment on the farm was  horse drawn ,and the steam tractor used to power the thresher at harvest time. Golden days lol.

No, im from the south east. Ive never been on the glenshne pass. The only times ive been to derry i went through strabane direction. Under lough neagh rather than over it.

I remember that big outtage, only thing was we had electric but no water lol. The father had to draw water from a well. Plus all of us children had a bug before the water went off so it must have been hard on them lol.

 
yes

Perhaps I am expecting too much from a heavy duty car battery and an inverter, but I have no idea what other small heaters there are.


If there was any viable way to get any half decent amount of heat from a 12v supplied system then it would have already been commercially produced for the camping / caravanning market.

If you take a quick search of heaters at one such camping supplier....

basically you get lots of gas or 230v supplied stuff...

Whether you look at running 12v direct or 230v from 12v via an inverter, you can never get more out than what the battery can give..

the only useful 12v supplied bits are a 12v kettle or a mini fan heater to de-mist your campervan windows.

If you do manage to work something out, you will probably be able to make a killing selling it to the camping marketplace..
