Hi, I renovated our house a few years ago. Not realising storage heaters may contain asbestos, I dismantled them without wearing a mask. I am pretty sure they were dimplex. The house is a 1930's ex council house. There are small electric dimplex heaters upstairs which may have been fitted at the same time, which would suggest they are all post 70's. I believe this is a good sign for them having been asbestos free? If anyone can tell there age from the photos I would be really grateful, unfortunately these are all I have. Thanks
