Milky Way. The Milky Way was once considered an ordinary spiral galaxy. Astronomers first began to suspect that the Milky Way is a barred spiral galaxy in the 1990s. Their suspicions were confirmed by Spitzer Space Telescope observations in 2005, which showed that the Milky Way's central bar is larger than was previously suspected.
CheshireBuilder New Member. The combi drill is a COMBInation of a hammer drill/sds/chizel and drill driver and the drill driver is designed simply for driving screws..ichiecatpugh New Member. previous post not strictly true :-. A drill/driver is just that-a drill with a torque control function which then allows it to be used in a controlled fashion for screwdriving. A combi drill is a drill/driver with the addition of hammer action which will allow drilling in masonry.
No, because a combi boiler provides heat for central heating and heats water for your taps on demand, there is no need for tanks in the loft or a hot water storage cylinder.he water is fed from the mains so the water pressure is generally good. However, depending on heat output, the flow can be limited if other taps are running at the same time. If you have more than one bathroom, a system boiler might be a better option.
