Bypass screw
CombiSmart is a simple, single length device with an external by-pass adjustment so it's easy to install and calibrate. Simply cut a section of pipework and attach CombiSmart to any existing wall hung combination boiler or multi point water heater.
No kinks, no bends
There are no kinks or bends - just a straightforward design for hassle-free installation without adjusting existing pipework. This prevents complications in the future, makes it easier to install and easier to fit in small spaces.
