London’s Leading Party Wall Surveyor, Building Surveyor & Third Surveyor – Bruce Spenser MSc MCIOB
Bruce, uniquely, provides the combined Building, Structural and home survey which he has evolved as the optimum and ideal Survey for London properties; period, mid-war, non-traditional design, new build, cavity, solid, modern methods of construction etc.
Please provide the full address & post code of the property to be surveyed, its asking price and a photo of the front elevation (estate agent’s link) for a fully comprehensive offer of professional services or email or call Bruce:
The non-invasive Building Survey will follow a disciplined iterative methodology and structural appraisal, including advice on loading and foundations to determine the structural serviceability and adequacy of property. Survey will advise of all possible and probable defects and their causes some of which are contained in the menu below:
Stromness 13 Feb 2016 – The question of the smokey fire
Safety First – fire = heat, fuel (carbon) and oxygen (o2). When these 3 are correctly balanced the fuel turns to carbon dioxide (co2) and water (H2O) when burnt. When they have inadequate oxygen the fuel turns to Carbon Monoxide an odourless, deadly gas which will put you to sleep before killing you.
Therefore all open fires must be correctly installed by a Registered Engineer and must meet the requirements of Building Regulations. The engineer will ensure that there is sufficient oxygen available via vents.
A Smokey fire is a warning that something is wrong, it must be put out immediately and not used until corrected by a Registered Engineer.
TheScience of a Smokey Fire:
A Volume of gas increases as pressure reduces and reduces as pressure increases therefore it will expand to fill the available space or can be directed by physical forces where ever you want it to go
When a fuel (say coal) is burnt it alters its state from a solid to a gas. The emitted gasses and particles (fumes) will fill a room if no other physical forces are in place. The physical forces which generally act on these gasses are as follows:
Heat which will force the gasses upwards
A flue within a chimney which will force warm gasses upwards
Therefore if the fire is placed directly beneath the flue within the chimney the fumes will move upwards within the flue unless stopped by other forces such as:
If the flue is cold a plug of cold air can restrict or prevent the fumes
Down draft from winds above can blow the fumes backwards
The fire opening must be less than 8 times the flue cross sectional area or the up draft will be inadequate and fumes will spill into the room
If the combustion is inadequate insufficient heat will be generated to assist the updraft and smoke and deadly carbon mon-oxide will enter the room
