INFRA RED UNDERFLOOR HEATING

[mross]

Yes, a heat pump can be four-hundred percent efficient but that's still going to need about 1kW of power.

I havnt bothered looking at the crap they obviously are spouting everyone knows lectric heating of any sort on an off grid boat is a nonsense. Oh wait just a minute are these the guys that market the " Eco Fan "

Well after all is was an Ecofan that made Marilyn Monroe and Julia Roberts Dresses Lift and Flutter in those Fillums ,Yes?

Potential there? an Open Frame Generator (RodneyGen) with adequate Output could run the Heatpump using around 15 Litres of Petrol in 24 Hours.

Funky Heat have told me that a narrowboat cabin measuring 12.4m long by 2m wide and 2m high would need infra red heating mats rated at 1.24Kw approx.

Mr OSS responded thusly...

They are talking rubbish. 

However, even if they’re not talking rubbish the figure offered by Robbo is correct when he stated...

It will be over 2400ah at 12v

Let’s put that into perspective.

A 4800Ah battery bank (absolute minimum for this demand) would cost around £3600 and would comprise 40 off 120Ah Batteries. That’s not considering the cost of cables and busbars of course. 

A 100A charger would cost around £1100. 

An EU30i genny to power the above charger would cost around £2500  

So far we’re well above £8000 for batteries etc  

The time to recharge the 4800Ah bank from 50% SoC would be between 36 and 48 hours.  So you’d only be able to actually use the heating every third day.

Other than that it’s a great idea.

You've neglected to account for the reballasting. Have you seen the price of scrap metal?

On their website they claim they can save you money.  Their salesmen may actually believe this.

A tea light, flower pot and an Ecofan is all that's needed to keep a narrowboat toasty warm in sub zero weather.

1.24Kw is what they assume a 'large room' will need according to their website. Of course, a boat isn't a large room

Yes, people actually believe you can heat a room with a candle!!!

An Axiom propellor on a Ecofan? I'd buy one!

You can, 0.01 of a degree rise, it is heat after all.

With enough insulation you could get it up to a comfortable temperature. Of course you would have to block off all the ventilation. Then you would die of CO poisoning from the badly burning candle flame. Then the candle would go out. I'll stick ith my squirrel stove thanks.

Anyone who falls for this claim should get a performance and cost guarantee first and check with a solicitor that it's legally binding!

And a cast iron insurance backed guarantee of performance.

Personally I am appalled the magazine did not think to check the claims with me before publication. I have a feeling for most things they have a caretaker editor. I have no idea about his technical competence.

But think what you’re saving with this uber-efficient heating. You could have the builder use 25mm plate up front...

As I said, I haven't done the sums. There's still a lot of heat in that there cut, though.

Waterways World was just as guilty last month with their review of the all-electric boat.  They gave a lot fo figures that most people would demolish in a couple of minutes.  I was very disappointed that WW published this article without casting any doubts over their ridiculous figures.  There once  was a time when Graham Booth would have torn it to pieces, but I guess the advertising revenue is just too much of a draw.

The problem is that when you need it most the efficiency is at its worst, basically the colder it is outside the closer to 100% it gets.
