I've got underfloor wet (from the main boiler) heating under oak flooring but it's not solid oak it's laminated (I think it's called that but it's plywood and then a 6mm top layer) and It's approved by the manufacturer for underfloor heating.
My builder said when he laid it that it's essential that you get a really good make as it's stressed much more with UF heating.
I've had it down for nearly 4 years and only had one issue where a board partially de-laminated. Not sure I could put it down to heating it might just have been a dodgy board.
I fixed it by levering it up filling it glue and then building a temp structure, braced off the ceiling, to force it back down whilst the glue dried. I then pinned it with a nail gun and filled the nail holes with oak filler.
I was warned off using electric UF heating due to cost, I never really looked into it as I fancied the wet stuff anyway.
