Depends on your age.
If you intend to spend longer than 90 days in Spain you MUST make it your county of residence and that will involve declaring your world wide assets and paying your tax there.
I will assume as you want to split the time that you wont be working and therefore wont be paying into the Spanish system. So if your under state pension age youll give up your right to the UK NHS and you will need private health ins (not the same as travel ins ) that must meet certain criteria in order to obtain residency. It also won't cover pre existing conditions.
If you are claiming state pention then your right to Spanish health care will be paid by the UK. You need to tell the DWP overseas team that your moving abroad and they send you an S1 form.
Check out Citizens Advice Bureau Spain website for all sorts of info.
There may be changes after Brexit. Like much higher income needed to obtain your residency as we won't be an EU country. Also no deal will mean no transition period so you may only have until March 19 to become legal there.
It seems clear that you have much research to do if you thought you could just go there and stay for 8 months.
If you have Facebook there are lots of good info groups you could join. Including one for MMGR I suggest you seek good tax advice as everyone's circumstances are different.
Good luck.
