I use it NOT AS FROST PROTECTION ... because of the following:
The thermostat of AKO frost unit goes below 11 degrees at room temperature.
This means the heater keeps the room always at about 10 degrees and the costs in the winter a whole lot of power.
Under Frostproof I mean a temperature of 4 to 5 degrees. (So half the temperature = half the cost of electricity)
I would therefore give it 3/5 stars ... BUT ... for this purpose, I did not so bought it.
AKO FROST PROTECTION for heating (for caravans / motorhomes):
Benefits:
- Small design
- Wall mounting
- Convector
- Accurate thermostat
- 600 Watt
Disadvantage:
- Slight hum / buzz (at least for my model)
- Insufficient heating power for larger rooms or in properly cold outside
Every camper has ever experienced the night all the gas, and the heater goes out ...
Then you have 5 ways ...
1. Freeze
2. Tighten the jacket and go out to the second gas bottle when it's cold and dark to join
3. Truma Ultraheat hire (with me because of the price of about 300 non-existent)
4. Truma DuoControl switch to second gas bottle (with me because of the price of about 170 non-existent)
5. turn on a little extra heating with electricity ... and here the AKO frost guard comes into play
The frost guard takes place in each Vova / Womo a suitable location for wall-mounting, as it is really small.
The acquisition costs are very low (have my bought for about 27 Euro).
The heating only consumes 600 watts or 600 watts of heat only (600 watts if it consistently heated one hour)
Invoice at maximum capacity:
- 50 cents per kWh at a campsite
- Heating runs on Maximum 8 hours
8h x x 0.5 = 2.40 0,6kWh
Assuming that the heater is not completely passed through, because there is no minus grade, and because you do not want to sleep at 25 degrees but, for example, 17 degrees ... the heating would run instead of eight hours only 5 hours ...
Invoice at normal capacity utilization:
- 50 cents per kWh at a campsite
- Heating runs through 5 hours
5h x x 0.5 = 1.50 0,6kWh
If you pay for an electricity charge at the campsite, you need of course not count;)
600 watts of heat is not much, why is an advantage but when camping ...
many campsites are not well protected, few have 16 amp fuse, I was already in many places with a 4A fuse ... that means here comes the assurance when more than 1000 watts are consumed ... so make coffee (about 800 Watt) while heating (approximately 600 watts) would not go there.
What bothers me in my model is the hum when the heating is on. I know of no convector heater makes noise when heated. The hum is relatively quiet. Compared to hot fan heaters (that work with fan) but the quiet hum is bearable ... Nevertheless, there is a star for less!
Conclusion: A solid piece of equipment that is wonderfully suited for my purposes.
