Hi David It seems to be like sludge is build up in your system or there is a more air in radiators. i would suggest to top up a system and try to bleed radiators if this won't help I would suggest to post your job description on main website then 3 companies will contact you to discuss details about a job. Profit of posting a job on Rated People is that it does not cost you a penny but you will receive 3 companies profile with a link for their rating so you would be confident to choose the right person for a job Best regards Rafal
