We recently had a leak in the ch system which brought the ceiling down !!! System drained and leak fixed but when trying to refill ch system no water coming to rads!! The expansion tank in roof is full though - assumption we have blockage in feed pipe! The question I have is do we just get someone to fix the blockage or, as suggested by them, change the system to an un-vented system? If so approx how much would that cost? BTW we have a megaflo hot water system if that makes any difference.
Any help would be most appreciated.
