I’ve been looking at purchasing a rocket stove for some time and considering either the EzyStove or the EcoZoom Versa. I’d be using it mainly at home and occasionally camping but portability is less of an issue over the cooking efficiency and heat it generates. I’ve not been able to find any reviews that give a direct comparison and would appreciate your own thoughts on these two models. Is one capable of burning hotter than the other? Is one more more efficient at slow cooking? And is one more durable and likely to last longer? When it comes to stability, is there much difference between the two?
Wild Stoves Technical Response
Most off-the-shelf rocket stoves are pretty similar: they’re all about 30% thermal efficiency, similar sizes, and similarly powered. The main differences between the Ecozoom and EzyStove are materials, weight and use of charcoal. EzyStove is much lighter and leaner on materials than the EcoZoom, for very little difference in performance. The EcoZoom is a tried-and-tested model that is much heavier as it includes cast iron top and thick insulation. These are all fine if you’re not carrying it far (or sending it by post!). The leanness of the EzyStove is one of the reasons we buy these in by the container – we see it as a significant advantage. But it’s not so significant if you’re not carrying it.
Note the EcoZoom versa can also be used with charcoal – hence the doors to reconfigure the firebox.
Is one capable of burning hotter than the other?
They’re similar heat output.
Is one more more efficient at slow cooking?
The EcoZoom – by virtue of its heavier build – tends to retain heat more which in design terms for a rocket stove is not ideal – but can be an advantage for maintaining a very small fire for slow cooking. But both stoves are very controllable for practiced users.
And is one more durable and likely to last longer?
Both are designed to last many years used in developing countries on a daily basis. Don’t expect either to look pretty after use – the paint jobs suffer in the heat of course, but the stainless of the Ezy and steel of the EcoZoom won’t be affected.
When it comes to stability, is there much difference between the two?
The EzyStove has a slightly wider footprint, but then the EcoZoom is heavier. So again, there’s not much in it.
