We have a typical 70s style 4 bed detached house with a warm air system (Johnson & Starley J55-65). Every year BG service the system and give us a notice saying that the system is not compliant with current regulations - this is because the return air flow is now undersized (it measures 14" x 9" and should apparently be larger?) - there is nothing we can do about this as the return air flow is built in to the house.
Does this mean that we can never replace the boiler with a new one because a new installation would have to be carried out in accordance to current regulations??? BG have suggested that a wet system with modern boiler would be more efficient that the warm air system but I cannot see how radiators and water running everywhere would be better. However, if we cannot ever change the warm air boiler then maybe we will have to change. An estate agent friend of mine also said that we should change to a more modern system if we ever wanted to sell the house.
Thanks for any advice.
