Excellent heat output
4/5
The Dragon 4 exceeded my expectations in terms of heat output, which is excellent. Once warmed up, which takes about 20 minutes, I had to turn down the thermostat. The radiator is hot to the touch so care may be needed with positioning away from anything likely to be affected. The radiator looks good and the ocassional 'clicking' of the thermostat I didn't find particularly intrusive. As mentioned the radiator does smell when turned on, even after the suggested 2hr 'high' setting on first use out of the box. Hopefully this will decrease over time, but for this small issue I would have rated 5*.
