As part of renovating an old property, I have to remove an unsafe external structure where the external boiler (very old! - grant 50-70 Euroflame compact oil boiler) is currently placed. I need to case or box in the boiler and the pipes leading into the house to protect it from the weather as it will, when I remove the structure, be exposed to the weather. It currently stands on a concrete surface which will remain.
I read around the subject but it is a little confusing regarding clearance regulations and suitable materials. I am considering allowing the following clearances. 200mm above, 50mm left and right, 100 mm front and 25mm all round clearance for the flu. I will construct it in such a way that any part of it can be removed for servicing if required. Does this sound about right, or are their definite regulations. I will be selling the property once renovated so I do not want it to come back and bite me! As the boiler is at least 10 years old I have no manual and cannot find one online.
What materials can I use, best to use? is it ok to use combustible materials such as external ply and felt for the slanted roof of the boiler house? or do I need to be looking at other materials. It needs to be weather proof
Would really appreciate experience, thoughts and advice, particularly from those who have done this.
