Adding Greenhouse Heater

Hi. We've just bought a greenhouse heater with a cover...longer than the tube so buns can't get to the tube....it's been pretty cold here the last week or so while waiting for delivery minus 5 lowest up to yet. Is it OK to add the heater to Frankie & Lilahs shed? Won't cause problems regarding snuffles etc? Thanks

I only switched mine on for the first time this year a day or two ago. The heat is very gentle and only raises the temperature but a few degrees so you should be fine.
