The 160mm bore is the standard choice for whole-house MVHR central trunk runs, higher-flow mechanical extract applications, and the air intake and exhaust connections on integrated heat pump water heaters.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eMVHR and mechanical ventilation\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe 160mm bore is appropriate for central MVHR trunk runs and main extract branches where 125mm ducting would create unacceptable resistance. Uninsulated ductwork running through cold loft spaces, undercroft voids, or unheated service zones loses a significant proportion of the heat it is meant to recover. Verplas Thermal ducting is manufactured from Neopor® graphite-impregnated EPS, achieving a thermal conductivity of 0.03 W\/mK — which at 20mm wall thickness delivers a thermal resistance (R-value) of 0.666 m²K\/W. This exceeds the minimum 0.625 m²K\/W threshold specified by the Part F 2010 Domestic Ventilation Compliance Guide and NHBC Chapter 3.2, and satisfies the requirements of DW\/143 Class A for duct airtightness. The insulation also prevents condensation forming on or inside the duct — a common failure mode in rigid systems routed through cold zones.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eHeat pump water heaters\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eIntegrated heat pump water heaters — also referred to as heat pump cylinders or air-to-water DHW heat pumps — typically require two 160mm duct connections: one for ambient air intake and one for cooled exhaust air. Models from manufacturers including Dimplex, Vaillant, and Ariston specify 160mm ducting for these connections, and manufacturers typically publish maximum permissible system pressure drops that must be calculated from the number of straights, bends, and terminations in the run before installation.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eInsulating both duct runs matters here for a different reason than in MVHR: the intake duct draws ambient air into the heat pump's evaporator, and if that run passes through a cold unheated space, condensation on the outside of uninsulated duct can cause moisture damage over time. The exhaust duct removes cooled, dehumidified air, which is even more susceptible to surface condensation in warm, humid areas. Verplas Thermal ducting addresses both problems.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eWhere a heat pump water heater is installed in a confined space such as a utility room or airing cupboard, ducting the exhaust to an adjacent space or externally also allows the unit to operate without overcooling the installation room — a practical consideration when sizing the duct run.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eSelf-Seal push-fit system\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eEvery component in the range uses Verplas's click-and-lock Self-Seal mechanism.

For heat pump water heaters, always consult the manufacturer's installation manual and calculate total system pressure drop before finalising the duct layout — the number of bends has a significant impact on resistance and can affect unit performance if the permitted maximum is exceeded.
