Frequently asked questions
- What is the difference between a manual and a thermostatic valve? A manual valve is used only to shut off or roughly regulate flow, while a thermostatic valve combined with a head automatically maintains the set room temperature without any manual intervention.
- What is a Eurocone (EK) connection? The 3/4" Eurocone connection is a standardised thread used on most radiators in Europe, allowing simple connection of valves and fittings without additional thread sealing.
- How do I choose the right fitting for a radiator? It depends on the radiator's connection size (most often 1/2" or EK), the type of piping system (single-pipe/two-pipe) and the pipe material (steel, copper, plastic).
- Are OPTIMA bathroom fittings compatible with standard radiators? OPTIMA kits are designed specifically for towel rails and radiators with an M24 connection; for standard radiators, use the standard fittings and valves with a 1/2" or EK connection.
