– Constant‑speed option – set a fixed speed between the minimum and maximum levels when a steady flow is preferred.
– Compact 130 mm port spacing – fits standard boiler connections without extra adapters.
– Low noise & low power consumption – ideal for quiet homes and reduced electricity bills.
– ERP‑compliant & ISO 9001:2015 certified – meets European energy‑performance standards and quality assurance requirements.
