my heaters are only blowing slightly warm what could be the problem?
a blockage.
1)re-bleed system is easiest and doesn't cost
2)if same check thermostat works
3)if not that i would try flushing system but only with hose pipe not pressure washer lol
Hope this helps
thanks will get cracking first thing its too cold not to have them working lol
let us know how you get on tomorrow ok
