Room heating - Elektroheizung or Heizlüfter

20 posts in this topic

Hello,

I live in an old apartment which doesn't have centralized heating. There is a wood oven in each room. I want to buy one of the following devices this week to avoid using the wood oven this winter-

My room is 20 square meters big. Could anyone please suggest which device would be better for heating and would result in low electricity bill?

The first device is a 2000W so will use more power than the 2nd device which is 800W.  However, the first device will keep you warmer and of course you can run it on level 1 instead of 2 and turn it off when you are warm enough.  The first gets good reviews.  I'd go with that.

Forget about it.

That heater is too small to heat a 20m² room.

You would end up leaving it on all the time, being cold and still paying a few thousand euros just for electricity.

 

There is a reason why no sane person in Germany uses electricity for heating - it costs 5 times more than heating with gas (and heating with wood is half the price of heating with gas).

1 kWh of electricity costs around 0.30€, 1 kWh of gas around 0.06€, 1 kWh of wood around 0.03€.

 

So unless you fancy a bill for a few thousand euros for electricity, use the wood heating that's provided.

And look for a different room for the next winter - one with central heating.

 

For the time being, I suggest getting an electric heating pad instead, to use in bed:

When it comes to raw heat generation there's no such thing as energy efficiency as heat is the end result of energy inefficiency. The laws of thermodynamics, entropy, and all that.

 

Do as Panda says. Heating with electricity costs a fortune!

I would agree with that.   Not had one at home for years but I ran a small location that had them more recently and it was always just so immensely serious to turn them off on leaving - running them until reappearing a week later would possibly have bankrupted us and at least drained our reserves :wacko:.     Absolute emergency short term back up at absolute most.

 

If you really must get this sort of device, then at least watch the meter closely from the start and do the calculations of cost early.

Heat with wood... 

 

for a 20m²  room, you would need about a 160€ worth of wood to keep you snug... 

 

Order Eich/Buche mix when ordering...  2 RM should be enough... 

 

Gas heaters wil create plenty of moisture, thus a huge Mold Magnet...

For the whole Winter?

Regardless of which heating solution you chose I would strongly support the suggestion of an electric blanket for your bed. It will not only keep you toasty warm but also help keep the bed and bedding dryer. 

 

Heating on a budget is always a thin line between keeping the heat in and letting the moisture that accumulates though daily life out - both in your room and in your bed.

 

An old skool woolen blanket is also an effective way to keep warm whilst self regulating moisture wicking.

electricty costs 5 times more in Germany than in the U.S. 

 

Unless your place is super insulated, and it doesn’t sound like it is.  You will need about 3 kWh of energy, either from electricity or burning material, to produce enough heat to warm your place.

 

I have found the best electric heaters are the radiant ones, they just sit there and quietly heat things.  They aren’t on ALL the time like the ones with a fan are, but don’t kid yourself, it will still be expensive to heat with electricity. 

But wow, it’s so nice to flick a switch on a device and get heat instead of dealing with the wood stove.  Is it more expensive than burning wood or coal?  You betcha. 

 

Another suggestion, don’t burn wood.  Burn coal.  25 kg of coal is only 5,79 EUR at Obi, that’s about 44 briquets.    https://www.obi.de/brennstoffe/braunkohlebrikett-25-kg/p/4413159   You can also buy smaller quantities of coal that are easier to carry home.  And, you can have bigger quantities delivered to you. 

 

But you will always have a mess to clean.  Sigh. 

 

I’ve been through quite a few electric heaters over the years.  The little 15 EUR fan units tend to last a season or so.  I also tried a glass panel “infrarot” heater.  It worked well, but after two seasons the switch broke. 

 

https://www.obi.de/elektrische-heizgeraete/infrarot-glaspanel-heizer-2-000-w/p/3515400 

 

Obi is pretty good about returns though. 

 

I also found the traditional electric Ölradiator is an effective unit. 

 

https://www.obi.de/elektrische-heizgeraete/rowi-oelradiator-mit-display-9-rippen-2-000-w/p/5985221  Also tends to last only a season or two before either the switch breaks or it starts leaking.    Again, Obi is pretty good about returns. 

 

The best electric heater, though it is no miracle device like the manufacturer says it is, is a Wibo Elektroofen with ceramic tiles.  https://www.wibo.com/elektroheizungen/elektroofen/    It does eat electricity and costs money to run, but it also does heat fairly well and makes no noise.  But Wibo only sells them through salesmen and they cost like 4.000 EUR.  Look for a used one.  They are heavy, so beware of that for transporting it. 

 

consider combining a 15 EUR little blower with a electric Ölradiator.  The blower can get the room warmed up faster than the radiator, and the radiator can quietly keep it warm.  But you'll be using power...  

 

An electric blanket is a good idea too.

That totally depends on where you live in the U.S. or in Germany.

Coal? Are you serious?

Yup.  Coal is neither renewable nor carbon neutral, but neither is natural gas. (and where does our German electricity come from anyway?)

Coal works great in a stove for heating.  Starts up easily with an Anzuendwuerfel and produces reliable, silent heat.  But it's a pain to clean up.

On a similar subject does anyone have experience of infrared heating panels. The very old gas heater with flue in my bedroom (seldom used) won't light up this year and may not be worth repairing, so looking for an alternative and those panels look very good.

Any advice would be much appreciated.

You mean like this? 

https://www.obi.de/elektrische-heizgeraete/infrarot-glaspanel-heizer-2-000-w/p/3515400 

  

It worked well for heating a 20 qm room, and was attractive.  Had a remote control that was handy.  couldn't use a separate timer (i.e. in wall socket) with it though because whenever it turned on it needed to be adjusted -- you couldn't leave it set at some temperature and cut the power to it and then have it stay at that setting when the power went back to it. 

 

Makes no noise.  That's nice.   The electronic controls on mine stopped working after a season and a half.  I returned it to Obi.

Not quite, I was looking at a wall mounted one such as

https://www.conrad.de/de/fenix-exclusive-700-p-infrarotheizung-700-w-12-m-weiss-1267643.html

As far as I can tell it is possible to use it with a remote controlled timer/thermometer plugged into the wall socket.

Slightly off topic but what is the general opinion of district heating? (Fernwärme)

Only 700W.  Well, that will obviously save on electricity vs. a 2 to 3 kWh device.  But how big a space can 700 W heat?  And mounting on a wall, that's a commitment that would outlive the life of any of the electric heaters I've ever used. 

 

On the remote control, any device that you plug into a wall can be used in combination with a plug in device.  Just make sure the wall socket can handle the wattage load.  See, e.g.:

https://www.amazon.de/gp/product/B07JGWC719/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

 

I wonder if an Obi "Convecto" stand would work to use the Conrad infrared heater without having to attach it to the wall?  https://www.obi.de/elektrische-heizgeraete/standfuss-convecto-600/p/1747336

Infrared heaters don't heat the space/the air. They heat objects like furniture and humans.

Eventually the heated objects heat the air, too. If the aim is to get a warm room, the number of watts you need depends on the rate of heat loss to the outside - usually mostly from the windows and doors. So there is no 'size of room' that can be heated by 700W - it depends on the insulation you have.
