I have been seeing post and forum of RMH
for green house.. but i have never really see any good review out of it..
did it work ?
Did anybody tried rocket mass heater exhaust buried in green house under the bed that work ? can to share please ?
i wanted to make it, but i need to do some research on what other have done.. why bother wasting time repeating mistake ?
.. instead of making raise bed using wood. i am planning to just bury the exhaust under the soil line and the places where the pipe goes, it will heap it up with clayiest soil.. to a certain height, like1 foot.. then on top of it i use normal soil for growing crop.
1 thing i don't know is how much distant does heat able to conduct in clayiest soil ?
i won't want to put so thick of clay that the root of vegetable get no benefit of the heat..
so the question is how much distant does heat travels in clayiest soil ?
how long of exhaust can i bury in ground can a normal oil barrel size
take before too cold to expel from chimney (that will be a failed heater, under i give it constant suction using exhaust fan) ?
my winter here is -7c here in UK. and day time is sometime around 0 deg c.
my winter target temperature is 7 deg c so soil temperature and some bed maybe is 15 deg c. but min should be 7 deg c.. else those over wintering plant will die. i lost way too many plant so far using propane heater to heat air... useless.
if rocket mass heater exhaust pipe is not working in green house (that means it is not practical to conduct the heat to a such a size of a green house (let's just say slightly larger than common size greenhouse 10 meter x 3 meter ), then no point of using it.. to heat air in poly tunnel during cold weather is just like throwing money into drain. futile .
if mass heater is not work, i will resolve to use the
to heat water and use motor to circulate PEX hose buried under bed.
is that when it is hot , it is too hot, ... might kill the root of plant... that's why i need to know how much distant does heat travel to each direction in clayish soil...
if anybody have tried such thing out, please advice.
