As discussed in the previous chapter, overheating a room increases running costs and digital thermostats help avoid this, but the mass or weight of a heater and the heating element used also has an effect.
Ceramic or stone core heaters can take a long while to heat up, so when the thermostat senses the room temperature has dropped and switches the heating element on, the room temperature continues to drop until the stone core produces enough heat. When the room reaches the required temperature the stone core may have too much stored heat causing the room temperature to continue rising resulting in ‘overheat’. In this instance the investment of a digital thermostat is wasted and running costs can be higher.
For over four decades Ducasa has been researching and developing electric heating. During this time their technicians have produced the Avant range which has the perfect balance of aluminium, fast acting heat transfer fluid and highly responsive heating elements. Initially when the radiator is switched on and the room temperature is lower than the required temperature the radiator will become reassuringly hot, yet still within safe temperature guidelines required for CE approval. As soon as the room reaches temperature the thermostat and built in microprocessor will switch the element off and on in order to replace just heat lost from the room – the result is a consistently warm, comfortable radiator.
