I have a 2 prong outlet and a surge protector
Those adapters are no longer used because it became obvious that even with the center screw used many boxes were still not properly grounded. In such cases if there is a fault to ground dangerous current could flow on exposed metallic parts, or flow through high resistance connections causing heat to build up causing fires.

NO! You cannot simply use an old water pipe, or especially a radiator for a valid and proper electrical ground. 

You really need to have a new circuit run. It is possible to find a valid proper ground for an old circuit, but to do so, and do so compliantly, is likely harder than simply running a new circuit.
