Can I use this device to switch on my heating remotely with my mobile or does it have to be connected to my house phone?

To do this you need to be able to connect the IP Power Switch to the Internet via your home network internet connection, give the IP Power Switch an IP address and make it visible from the outside world. Provided your mobile phone is Internet enabled then you can contact the power switch by typing in its IP address in the browser. You can also use the timer/scheduler option on the power switch to switch devices on and off. Depending on the kind of heating equipment you have, we would advise sensible caution when switching on and off remotely.
