when i built this shed i put some r NUMBER_TOKEN rigid styrofoam insulation behind the cladding and now i'm curious how long i can get it with a space heater in the winter and i'll be using this drill space heater and drill also happens to be the sponsor of this video and to record my measurements i've actually got several temperature sensors one here one further down and one at the bottom plus another one just outside here all connected to a little raspberry pi computer to log the data this is also connected to my wi-fi and i've also got a smart plug for monitoring how much power i'm using let's turn this thing on and it's going to try to get to NUMBER_TOKEN degrees fahrenheit uh and i'll turn on the oscillating feature which will distribute the heat a little bit better and now i'll just leave all this alone for a bit close the door and watch the data from inside the house that heater's been running for NUMBER_TOKEN minutes now so let's see how it's doing so the heater when i turn it on immediately drew a thousand watts uh kept going at about that same power level voltage dropped a little bit and the temperature of course immediately started to rise i've imported my data into trusty old excel NUMBER_TOKEN and here is a graph of the first NUMBER_TOKEN minutes of heating the blue line is the heater power scale to fit on the graph the purple line is the outside temperature which is rising slowly over the day and the inside the shed temperatures actually started out below the outside temperature because it's been a cold night and then we can see it rises very quickly staying a bit cooler near the floor but already we're at about NUMBER_TOKEN degrees i've also scaled this to fahrenheit so we're starting at about NUMBER_TOKEN degrees inside and then here we're up to about NUMBER_TOKEN degrees at head height that heater's been running for two hours now so let's have a look whoa it is balmy warm inside this shed now and the heater is just shut off because i guess it's hit its temperature set point and looking at the roof i can see there is a line of melting right about here which happens to be where where the purlins is there's insulation between those but the wood itself doesn't insulate as well here's my temperature graph over two hours and it hit NUMBER_TOKEN degrees at head level when the heater hit its set point and given that slope i think it could have easily gone up by another five degrees before it reached equilibrium when the heater did turn off it was actually only off for about five and a half minutes and the temperature dropped by about seven degrees on all readings there's also a persistent difference of about seven or eight degrees between head level and foot level and here's the same graph in fahrenheit and interestingly enough the foot level sensor was about NUMBER_TOKEN degrees and the heater was set to NUMBER_TOKEN degrees so pretty close at floor level of course further up it was much warmer and now turning off power for that heater with my smart plug to watch the shed cool down again and here's the two hours after turning off the heater you can see of course it dropped getting closer to the outside temperature which is by now risen to about two degrees but surprisingly it's dropping off fairly slowly so that shed does seem to be retaining some heat and same graph again in fahrenheit this heater also has some safety
