Hello,

I live in a small 2 bedroom end of terrace house. I have a Worcester 28Si Boiler in the corner of one of the bedrooms. I have been thinking about getting a joiner to box in the boiler for both aestetic reasons and also to reduce the noise the boiler makes (possibly lining a wooden built in cupboard with soundproofing material). My main issue is how much ventilation does the boiler need? In an ideal world I would like to have a completely sealed unit around the boiler so that I can reduce the noice the boiler makes in the room however I am aware that boilers need a certain amount of airflow. Saftey will always take priority over other things. If you can help advise it would be much appreciated. One option I have wodered about if it is required is cutting a hole in the ceiling and providing ventilation from the attic. Also assuming ventilation isn't an issue how much room should be left around the boiler.

firstly it depends upon the appliance in question. most modern appliances are ROOM SEALED and do not rquire ventilation for combustion purposes however may require purpose made ventilation for cooling. on the other hand many new appliances do not require ventilation for cooling within a compartment /cupboard due to the very low surface temperature of the appliance during operation. the only sure fire way to know this is by consulting the manufacturers installation instructions. this will clearly spell out any requirements. secondly, you must adhere to the manufacturers instructions as to any CLEARANCES required, this is not just because of heat and combustible materials but also to allow enough room for maintenance purposes ie replacement of parts it is refreshing for somebody to actually think of these issues before boxing an appliance in hope this helps TIM

check the manufacturers instructions for ventilation and clearance requirements
