wiring for boiler

[bmw530driver]

Can i use 0.75 mm flex to run from my c/heating controls in my airing cupboard to my worcester cdi boiler. I have had to replace the existing twin &earth cable with min 3core plus earth to accomodate pump overrun facility and all i had to hand was 7 core 0.75 mm heat resistant flex ..... will this be sufficient?
