Can someone recommend a GH heater?

[Guest]

I have tried 4 different heaters. Can someone recommend a GH heater? The GH is pretty tight with no holes.

More about the structure than the heater double wall or better single layer is unheatable in certain climates 6 and under you definitely need a double layer GH.

Chinese diesel heater for $189. Use an old 12volt battery with a trickle charger on it.
