DiversiTech stock a range of boiler condensate removal pumps that are ideal when the boiler condensate can not be removed via gravity. The tank pumps use a small bore of flexible hose which can be routed above or below doors, windows or under kitchen cabinets. When routing hose through any area which could be exposed to freezing temperatures, such as lofts, basements or garages, we strongly recommend increasing to at least 32mm plastic pipe and insulating.
