Group: Forum Members Posts: 30, Visits: 106	I am about to build an mdf oven, the size will be L1220mm, W610mm, H635mm. I was going to use a 2KW fan heater as i'm aiming for Max Dwell temps of 80 to 85c, but after reading one of Morepower's posts ( Hi Morepower hope you dont mind) and seeing his AMAZING work i understand that a 3KW needs to be on full most of the time to make 85C (not shore how big his oven is) so it looks like my 2kw's out of the window. Can anyone give me advise on will this do or is it OVERKILL for a mdf oven of my size?? 5kw single phase External size H300 W520 D200 Attachments $_3 (1).JPG (893 views, 37.00 KB) $_3 (2).JPG (890 views, 65.00 KB)

There is a 50mm base of Kingspan which I put the MDF box on top of. I put the same Kingspan round the sides... well mostly I have to get some more to be honest but I am going to make a new oven soon as the shape needs a change. (MDF is cheap to use and try,if you find need to make changes), 10mm MDF is actually very good at keeping heat in. I have 2 degrees difference from top to bottom. One option I have been looking at is using a workbench for the frame as I had to get a 2.4meter long bench and the shelf seems perfect for the moulds I have. 900mm high, 900mm deep and 2.4m wide. I think it would would make a good oven with a bit of work. This is the inside of the current oven.. I only put my MTB in there to clear some space and give a mate an idea of the size... 3kw works perfectly with this sized oven. Hi Morepower, thanks for your info and pic!. I had the 2kw fan heater sat around at home so i can class that as no cost and my plan was to go with that and mdf and celotex\kingspan to keep it cheap so thats good news to me!. When i bought the controller unit ect the 5kw fan\heater unit came with it so if i ever want to build a permanent oven i've got them there. We must think alike i had a look at a workbench with the aim of converting it but with the price of galvanised sheet and kingspan ect (and not knowing i could use plywood ect) it wasnt cost effective so mdf it is!. Cheers.
