replacing heaters

[fuzzysig]

i finally checked what model heaters i have and turns out i cant even find the model number anymore. they are so old

markel hf3125e is the model number if anyone knows anything about it


im looking for the most efficient heater i can find minding the cost of course

And what type of heater do you whant? Or what heater is the old one? A picture if you can.

If electric is your only option, heat pump is the best choice if you can afford it. Apart from that, a reflector type incandescent or halogen lamp makes a very good infrared heater and is very cheap.

All resistive heating is essentially the same energy efficiency, but they do vary in how effectively the heat is delivered and if it does other useful things with the electricity first. The reflector bulb directs its heat so it can be very effectively used. A PC mining Bitcoins (or Litecoins) can "subsidize" the energy used, in some cases being economically competitive with a heat pump or even returning a profit.

From the dimensions given, it looks like your heater has been superseded by the 4400 series. It looks like they quit making a 2500 Watt heater in this size, the largest you can get from them is 2000 Watt (I don't blame them).

Priced around $200. Not bad for a $29.95 space heater in a pretty box. But it will fit your hole.

As to efficiency, it doesn't matter whether you run an electric skillet, a toaster, a stove element, an amish hearth heater, or a heat lamp. These all rely on plain old friction to produce heat and cost about as much to run as a kerosene heater.

For the same price, you can go buy one of these and start saving money:

If I lived where you do, this would already be gone.

That's correct in the technical sense, but not in the practical sense.
A set of heat strips are almost 100% efficient at making heat (ignoring the small amount of light they put off) and a reflector light bulb only 90-95%, but for the purpose of staying warm, it uses much less energy to use the light bulb. In that context, the light bulb is more efficient.

Likewise, a PC mining Bitcoins (or some other online currencies like Litecoin) is also about 100% efficient at making heat, but the Bitcoins it "mines" can be traded for cash. In some cases, it can make more money than the cost of the energy used, while still making heat. Not even a heat pump can economically compete with that.

Mike,

I challenge you to build a bitcoin mine that will:

1. consume 2000 watts (to provide heat),
2. fit in this cereal-box sized hole,
3. live long enough to heat the room.

Blade server hardware easily gets that level of power density and more. Granted, it's not the most practical way of building a Bitcoin miner, but it's possible. It's pretty common to come across a 1kW rack server PSU that is smaller than a CD-ROM drive. Hardest part is finding GPUs that will fit.

i dont know anything about this at all anyone can give me a quick few words comparison?

which one is best efficiency

the initial price or upgrading vs long term savings etc...


i replaced all my lights with LEDs but with these heaters i havent really noticed any less power being used

[NiHaoMike]

Just get one of those cheap ceramic heaters if you're on a tight budget, or a heat pump if you're looking for long term savings. Building up a Bitcoin/Litecoin box or two is another option if you're OK with "experimental" technology.
