Enhanced Heat Exchange Electric Heater

[SkyWatcher]

Hi mike, wanted to comment a bit on your oil furnace comparison.
Would it not be better to compare this leo perron heater to other typical space heaters.
Typical space heater uses 1500 watts and outputs around 5000 btu's.
That's around 3.3 btu's per watt.
I don't know the btu output of the oil central heater they were using, though your estimate of 4000 watts looks close,if we take efficiency and the on-time of the furnace into account.
4000 watts would be an averaging then, if we say 10 minutes on per hour.
So maybe the oil furnace is outputting around 12,000 btu's averaged over an hour, for a 100,000 btu or greater oil central heater.
So the typical space heater would require around 3600 watts continuous to match the average btu's of the oil furnace.
The Leo Perron heater is only using 400 watts and around 1300 btu's, if we assumed it was the same efficiency as the typical space heaters for sale, again, around 3.3 btu's per watt.
However, since we don't know the output of oil furnace they were using and its efficiency and how long it was on per hour, we are only guessing anyway.
However, if we guess that the oil furnace was heating whatever space, at an equivalent 12,000 btu's average, then either were missing a bunch of data, or Perron's heater may be very efficient somehow, considering 400 watts continuous at 1300 btu's, should not be able to compete with 12,000 btu average from oil furnace.

Another observation.
The room i tested my Perron based heater in, used a regular 100 watt bulb and yet it raised the interior of a lossy 300 sq.ft. room with external door with glass and 3 very lossy skylights and vaulted ceiling, by 5 degrees F.
Is this supposed to be possible using only 330 btu's, if we assume it has similar efficiency to the typical space heaters for sale.
Or does it seem like, to do this, would require two or three times the amount of btu's.
Bear in mind, my model so far, is probably not as efficient as Perron's device.
I mean, i could maybe see a 100 watt bulb keeping a very small bathroom warmer, but not a room this size, with all the thermal loss in it.
Any thoughts appreciated.

Hey Sky

Yeah good thinking, keep thinking it over. I lived in cold country much

of my life and some I know live further up where it is even colder so this

is what always comes up. Insulation and exterior wall thickness.

One man I know can heat his place in 30 degree weather using a candle.

I called him an exaggerator but he assured me it was true. I asked him

how and he said his exterior walls were made of 12" X 2" floor

joist. So what we learn is that one mans house is different from the

next with no way to actually compare notes.

However with careful monitoring I can see you running tests with

the right KILOWATT HOUR METER on your 1500 watt oil heater and

then do the math against the light bulb heater.

The 4000 watt unit I was talking about was raw electrical current

dumped into a wire that glows red and the furnace fan blows over it.

Many of them are 20 amp elements at 240vac.

Remember the conventional oil filled floor heater will turn your

rooms into a sauna if left running day and night. These heaters have

thermostats that constantly turn on and off so as not to boil the oil

at some point. So again to be fair careful kilo watt hour measurements.

I know it may seem like a better deal with the 100 watt bulb when it's

not to cold outside. Since all conventional heaters max out and turn off

or cycle intermittently the investigator must have accurate readings

as a base line to be able to compare with.

I think that light bulbs have been used to heat rooms with for over

100 years. The kids easy bake oven makes good bread using a bulb.

In 1965 my girl friend use to love to make bread for me in the summer,

she was a doll. I was head over heals.

That light bulb oven always stuck with me. It had a sort of metal flashing

guard over it that often would bow over and touch the bulb and this

may have transferred the heat better, I don't know.


The main thing here is options, say your heater stopped.

Also you will save money over the larger element because we

all pay extra for a large surge of current each time the element

kicks on, did you know that?

I have seen large units cost 15 cents per each time they kick on

where the smaller units that run longer only 5 cents per kick on

of surge current. This is also true of larger AC units for a store or office.

Measuring accurately is easier said than done.

You will save money over the conventional design however small

based on these thoughts. It's not magic but it will save power.

In the quest to save energy the topology for turning on and off

large AC compressors and high current heaters has changed by

finding ways to keep the units running at reduced power without

turning them on and off. This is done by VFD variable frequency

drives. Yes you are on the right track.


This is my mind on the subject.

Hi mike, thanks for the reply.
I am tweaking the single bulb heater some more and when the heat wave tapers off here, will see how it improves.
It sounds like the fellow heating his cabin or house with a candle, has very good insulation factor going, his own body heat would do the job.
Do you recall the Xanadu model houses that were in Florida and maybe elsewhere.
They had tours through them and were supposed to be the future advanced house.
Those had very thick, urethane foam external walls i believe and probably could be heated with very little.
But what a shock, they closed down and nobody kept them up.
So everyone sees that and thinks they're pieces of junk, not realizing perhaps how cheap they are to heat and cool and maintain.
Heck, a paint job once in awhile and it's good to go.
