Yes, on a modern condensing boiler the Outdoor Weather Sensor makes the unit more efficient by modulating the boiler output. This means that the boiler is more likely to remain in condensing mode for longer periods.
Yes, our entire product range can be adapted to LPG except the Sirius FS 400kW and 525kW models.
For the Eurocondense three and Sirius FS series - these are conventional flue. For further details on the flue please refer to the sales literature or a flue specialist.
We would recommend either our Sirius units or the Paramount three units. On a system that has a temperature rise of 11ºC, in our experience, the Paramount Three units are more suited. However, regardless of the unit that you choose to fit we recommend that the system is flushed and treated with an inhibitor and an air/dirt separator is fitted on the return system to the boiler.
