How long does a natural stone radiator take to heat up?
Natural stone radiators take longer to reach the maximum operating temperature than ordinary heaters due to heir heat retention properties. It takes around 20-45minutes for stone radiators to reach their maximum temperature depending on the model type. Once this temperature is reached the stone will store heat, resulting in enormous energy savings (… advantages). Also, due to these properties the radiator will stay warm for around 1.5-2 hours after it is switched off.
