would it work if i put the Anti-static wrist-strapto radiator?
In the UK, all pipework entering your household should be earthed also. They usually earth your incoming gas and water supplies so that in the event of an electrical fault in your property and pipework becoming 'live' your supply will disconnect. Most houses etc. built in the last 20-30 years have their incoming water and gas services earthed. So you should be fine connecting your wrist strap to your radiator
