The madness of having external boiler houses is very clear now that a heavy fall of snow is covering the ground. The photographs below show the amount of heat being lost and wasted from the typical external boiler house. The first photograph below shows that heat from the boiler has melted the snow on the roof of the boiler house. The second picture shows the boiler house located at the rear of a garage. What seems to be a path which has been cleared in the snow has actually been caused by below ground heating pipes linking the boiler to the property, warming the surrounding ground and melting the snow. The last photograph shows cozy cats using the wasted heat from the boiler house to keep warm. What a useful investigation tool snow can be!
In these energy conscious times why are we still locating boilers in remote buildings/ boiler houses? One of my friends has positioned his boiler in a green house close to his house to try and put the, otherwise wasted, heat to some use. He has also installed extra insulation on the pipework between his house and the boiler. But the best solution in my opinion is to locate the boiler inside the property thus protecting the boiler from rust and reducing any heat loss to a minimum, but within a fire proof and externally vented room. Building designers and self builders take note.
Reasons to avoid building a separate boiler house
- There is heat loss from the pipes transporting the hot water from the remote boiler house to the property.
- The boiler itself releases heat during operation, it is better to have this heat released inside the property rather than outside.
- The humid external air will be in contact with the boiler and associated pipework and shorten the life of the boiler, (by rusting).
- The longer lengths of pipes hidden from view by being buried in the ground increase the likelihood of leaks.
