Is There an Exercise Bike That Generates Heat?

AI Thread Summary
The discussion revolves around the feasibility of exercise bikes designed to generate heat for home heating. Participants note that even a highly trained cyclist can only produce about 0.2 kWh of energy, which is insufficient to heat a small room effectively. Comparisons are made between the energy output of a bike and the cost of electric heaters, highlighting that traditional heating methods are more efficient and cost-effective. Suggestions include considering heat pump technology, but the costs and practicality are questioned. Overall, the consensus is that while the idea is interesting, it may not be practical for significant heating needs.

Hi all,

I was wondering if there was such thing as a heat creating exercise bike. Made for the purpose of creating heat.

It's really cold and the power bill is going up and I am wondering if this idea is stupid or has it already been tried. I would buy one.

Any thoughts?

If you are a racing cyclist you can probably put out about 1/3 hp for an hour - or approx 0.2kwh. That much electricity would cost you about 2c but it would take about a big-mac worth of calories.
 
So you are saying that even if I were a racing cyclist (which I am not), not much energy could be produced? Not enough to heat even a small room?

I'm not sure if you were saying that 2c is "2 cents".
 
Electricity costs around 10cents / kWh - that is 1kW of power for an hour.
1KW is a single bar electric fire or a small fan heater.
Unfortunately you can only generate around 1/5 of a kW.

Why not build it like a heat pump and amplify the energy of 200 watts into the equivilant of 800 or more ?:smile:

$1000 racing bike
$200 trainer
$100 cycling shoes
$50 silly little cycling shorts
$10k heat pump + digging up nearby 100m^2 of land to install pipes
Generates 1KW
or:
1KW Fan heater $10
1Kw hour electric 10 cents

ps -- Of course if you cycle enough to generate a reasonable amount of heat you will have the sort of bulging muscles to become irresistible to evo - then staying warm will not be a problem.

lol, I was waiting for the "Priceless" to come in at the end of mgb_phys's post. =)

Sounds like one of those commercials.

Hey!
What about stimulating the economy.:biggrin:
