Heating and Plumbing for a Loft Conversion
Turning a loft into living space usually removes the water tanks that were sitting there, changes the existing flue route if it passed through the roof space, and adds new radiator or en-suite pipework that has to travel up through the house..
Turning a loft into living space usually removes the water tanks that were sitting there, changes the existing flue route if it passed through the roof space, and adds new radiator or en-suite pipework that has to travel up through the house.
Tanks have to go somewhere
If the loft held the feed and expansion or cold storage tanks, converting the space means either sealing the heating system to remove them or finding them a new home in a smaller void.
Flue routes through altered roofs
A flue that used to pass cleanly through open loft space may now run close to new stud walls or insulation, and clearances need rechecking against the new layout.
New pipework climbing three floors
Feeding a loft en-suite or radiators means running supply and waste pipes up through two floors below, usually within existing risers or new boxing.
Questions we get asked
Can I keep a water tank in a smaller loft space after conversion?
Sometimes a reduced tank can be relocated within remaining eaves space, but sealing the system to remove it entirely is often simpler.
Do loft conversions always need a saniflo for the en-suite?
Not always — it depends on whether a gravity fall to the existing stack can be achieved from the new bathroom's position.
Will the loft conversion affect my existing flue?
It can, if new insulation or stud walls close in on the existing route. We check clearances as part of the plumbing plan.
