I need to find a 220v wall mounted or stand heater that pushes more than 4000 heater watts for my parents small home. Ive looked all over. Can anyone point me in the right direction? Please! Thank you

How about something like this:

Strat must have misread your question, you did not ask for a water heater, perhaps this link will be more appropriate:
