No. You must check your manufacturer's manual. Some heaters, especially gas-powered units, may have ventilation requirements or have combustion warnings that make blankets dangerous if installed incorrectly.
The R-value measures thermal resistance. A higher R-value generally means better insulation, though diminishing returns occur after a certain thickness. Balance this with the ease of installation.
