Is it just me or didn't we have 'scientific evidence' from Brodex showing why it is wrong to use hot water systems and hence why they do not sell one. Been examining their new crash test video and what do I notice featured on the right of the screen, but their new 'Flame Hot Water System' !!!! You can simply add it to any existing Brodex system (or even DIY systems) for just £3,800.
They also do a gutter-vac now as well.
