Upgrade Investment Payback

If I upgrade to a remote control system for my boiler, I have to pay an extra £80 pounds.  Assuming payback in 2 years, I will have save minimum £4 a month.  Since I have a low usage, I need to half my consumption in order to achieve the saving.


The extra control also takes up electricity, and also means I will have to leave the router on, that minimal amount of electricity about let say 1p per day.  In the grand scheme of things, I can omit the router cost.


The simplier controllers is likely to have a longer life, so logically I should use a simple controller, even though the thought of being a techie is fun.
