Product Overview


Each greenflame unit houses a substantial pellet store which is automatically fed, giving peace of mind to the user. A warning light also signals when the store requires re-filling.
With a simple regular check of the combustion chamber to remove ash and filling the hopper with pellets is all that is required to ensure smooth running of the system. Greenflame PLUS models include the following;
GSM Modem - Is the facility to utilise a normal phone SIM card with a data package (similar to a SIM used in a USB modem for a laptop).
The user can then turn on or off the boiler by sending a text to the modem from the phone.
A low pellet alert will also be sent to the users phone.
Heat Meter - An approved industry standard heat meter is supplied which can be fitted to theunit to measure heat generated by the boiler.
