Are there any energy-saving heaters?

It's no secret that if the electricity to heat the house in winter, in most cases, have to pay the bills a lot of money. On this basis, the Internet has divorced a lot of scams that promote energy-saving heaters.

I decided to find out: whether there can be energy efficient heaters, and if so, how much they can save money?

Go!

My first argument against the "increased efficiency" heaters is that on the average at any of the oil heater efficiency is 97-98%. Judge for yourself: how much electricity is needed to heat the filament, the same amount of thermal energy stood out in the atmosphere of the house. Loss - minimum - resistance to metals.

second - as the main advantages over oil-gather "energy-saving" heaters exhibited that the past - convector type. Are heated to high temperatures - so effectively - the manufacturers claim.

It turns out that energy saving heaters - a myth?

In fact, though the middle. In fact, these heaters do better than normal oil or convectors. But that's not the fact that the sellers have embraced.

1) The thermostat is connected to them - which means that heaters do not heat the house too much. And as is known, the more you heat the house, the greater the delta in temperature inside and outside.
The result - more heat loss.

2) The heaters are intentionally made small capacity - 400 watts.
So they do not overload the network, which is especially important if you heat cottage or country house, where there are voltage drops.

3) These heaters supplied relay SIM cardThrough which you can remotely make and break the network and to heat the house only when you are going there for the weekend.

These three steps do make energy-saving heaters, but not those assurances at 100% efficiency and the convection principle, which the manufacturer says.
