Manual or Thermostatic Radiator Valve? Which to Fit Where
Manual or thermostatic radiator valve — it’s one of the first questions we’re asked once a restored cast iron radiator is ready to go back on the wall. Both do the same basic job: every radiator needs a valve to let hot water in. The difference is how that flow is controlled — by your hand, or by the temperature of the room — and that decides which one belongs in which room.

The shine is hand work Hand polishing is where Radrestore began, and it’s still the pinnacle of the workshop’s craft. Every polished radiator is stripped back to bare iron and polished…

Municipal Hotel Liverpool: Bringing Its 1868 Cast Iron Radiators Back to Life
Did you know? The Municipal Hotel Liverpool’s cast iron radiators date back to 1868. Municipal Hotel Liverpool: a Grade II listed challenge Built in 1862, the Municipal Building in Liverpool — today the Municipal Hotel Liverpool — is a Grade II listed masterpiece. Preserving its original features, including the cast iron radiators, was paramount to the hotel’s restoration project. Some of the radiators are circular and intricately designed, in keeping with the building’s Second Empire architecture and its French-influenced detailing. That made them a unique challenge: each one is one-of-a-kind, so any leak or imperfection couldn’t simply be fixed with…
