If you regularly work on larger domestic or small commercial properties (up to 40 radiators, 3 storeys), the CF90 is a better fit. The CF90 has a 57L tank, 150 L\/min flow rate and 200 mm wheels. For most domestic heating engineers, the CF40 is the optimal balance of performance and portability.\u003c\/div\u003e\n  \u003cdiv class=\"kc-faq-item\"\u003e\n\u003cstrong\u003eWhat chemicals should I use with the CF40?\u003c\/strong\u003eKamco Power Flush FX2 is the recommended one-shot flushing chemical for steel\/copper\/plastic systems. For aluminium radiators or heat exchangers, use HyperFlush instead. Always follow with a DWTA-approved corrosion inhibitor such as SystemSafe DM. FX2 must be neutralised before disposal using Kamco Neutralising Crystals.\u003c\/div\u003e\n  \u003cdiv class=\"kc-faq-item\"\u003e\n\u003cstrong\u003eCan I connect the CF40 to a combi boiler?\u003c\/strong\u003eYes. The most common connection method for combi boilers is to connect the CF40 across the system pump ports (removing the pump) or across the boiler flow and return after isolating the boiler. The included BSP adapter set covers the most common UK boiler and pump configurations.\u003c\/div\u003e\n  \u003cdiv class=\"kc-faq-item\"\u003e\n\u003cstrong\u003eIs free training really included?\u003c\/strong\u003eYes — every Clearflow purchase includes one free proficiency training place at Kamco's St Albans Training Centre. Kamco also offers a Weblink scheme that lists Clearflow-trained engineers on their public directory, which can generate new business from homeowners searching for local power flushing services.\u003c\/div\u003e\n  \u003cdiv class=\"kc-faq-item\"\u003e\n\u003cstrong\u003eCan I use the CF40 for descaling?\u003c\/strong\u003eYes. The acid-proof construction means the CF40 can circulate Kamco Scalebreaker descaling chemicals to remove limescale from boilers, water heaters, calorifiers and heat exchangers — making it a dual-purpose tool worth investing in for hard water areas.\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Kamco","offers":[{"title":"Default Title","offer_id":63667469156701,"sku":"CL40CF","price":1390.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/2051\/3629\/files\/ClearflowCF40EvolutionPowerFlushingPump240VoltwithStarterKit.webp?v=1772367116","url":"https:\/\/qualityheating.co.uk\/products\/kamco-clearflow-cf40-evolution-power-flushing-pump-230v-up-to-25-radiators-39l-tank-with-start-kit","provider":"AIZO Quality Heating","version":"1.0","type":"link"}
