There are two basic sizes available - 2kW and 5kW. The capacity claims are inconsistent, and often incorrect. Those that are advertised as 8kW are really 5kW heaters. Some that are claimed to be 2kW are really 5kW heaters. The actual 2kW heaters are physically smaller than the 5kW heaters. Look at the dimensions to know which one it really is.

They work fairly well. Your battery is used for two purposes - initial lighting, which uses a LOT of current, and ongoing running of the fan and pulsing fuel pump, which does not take much current.

Many friends are using them to heat fish houses, and they work very well for the purpose. They are not thermostatically controlled. You adjust the pulse rate of the fuel pump. They have a minimum heat output to stay running, maybe 20%.

It is nice that one can easily keep a quantity of fuel in a small can. However, now with most diesel containing a bio component, it does not store well - it grows a black algae in the fuel.

There are some models available that are all assembled in a case, ready to go. Heater, fuel tank, fuel pump, etc. Others come in pieces for you to assemble.

All in all, this is a pretty compact and inexpensive way to have a small amount of backup heat.
