No but I’m commenting to see if anybody has input. I’ve been curious about the same. Or even using a water heater with some piping to create radiant heating

FFIW I’ve got an electric heater 2000w
And energy provider (UK) supplies cheap rate 23:30-05:30 at 7.5p per KW (instead of regular 37.5p)
If I didn’t have that I’d be looking at water or compost storage heater

I don’t see 300 watts being enough power regardless of how large your storage is. Then add some type of heat exchanger and add power for a fan to blow across it.
From my experience the only greenhouses that do well with heating are small or have good insulation. If you don’t have either/both of those it’s not worth the cost.

I am not sure why more people don’t do something like this. I used a much smaller one to heat a tub of water and floated my chilli’s on it to get them to sprout. I had the heater lying around. I sat it In my shed window, it got quite hot, but only locally, mini sauna. i have envisioned having a barrel of water with a heater in it and have an aquarium pump to pump water in a pipe around the green house like how they used boilers and radiators in old mansions or schools but more diy.

We have a hot tub in ours. Does that count?
