The Ideal Logic Max Combi2 C30 is a 30kW mains-gas combi boiler built for small to medium UK homes needing reliable heating and hot water from a single, compact unit. It carries a 10-year parts and labour warranty (registration required within 30 days of installation), delivers 94% ErP seasonal efficiency, and comes with an Ideal System Filter included in the box to protect the heat exchanger from day one. Designed, developed and made in the UK, it's engineered around the same installer feedback that shaped the wider Logic range — easier front connections, a push-fit PRV, and full-front serviceability that cuts callout time. Approved for a 20% hydrogen gas blend and compatible with Halo smart controls, OpenTherm modulation and solar thermal pre-heat, the C30 is a future-facing choice for anyone upgrading an ageing combi or replacing a system boiler with an all-in-one unit. Its low 28.6kg installation weight and 278mm case depth mean it drops into most standard kitchen cupboards without structural changes. 30.3kW Max DHW Output 94% ErP Efficiency 10 Yrs Warranty* 12.4 L/min DHW Flow Rate Class 6 NOx Rating 28.6kg Installation Weight Gas Safe installation required. This is a mains gas appliance and must be installed, commissioned and serviced by a Gas Safe registered engineer. Installation must follow Building Regulations Part L and current Gas Safety (Installation and Use) Regulations. 10-year warranty terms: The full 10-year parts and labour cover applies only when the boiler is registered with Ideal Heating within 30 days of installation. Unregistered units default to a shorter standard warranty period — check current terms at the time of installation. Sourcing note: Manufacturer specification confirms a 28.6kg maximum installation weight and 700 × 395 × 278mm (H×W×D) casing for the C30 model, consistent across the official Ideal Heating spec sheet and installation manual. Some third-party retail listings show swapped height/depth figures or a differing installation weight (32–35kg) — these are transcription errors from older listings and are not reflected here. Intelligent Pre-Heat The boiler learns your household's hot water usage patterns and pre-heats accordingly, cutting the wait for hot water at the tap without leaving the system idling unnecessarily. Included System Filter A 22mm brass Ideal System Filter ships in the box, capturing magnetite and debris before it reaches the heat exchanger — extending service life and protecting the warranty. Hydrogen-Ready Fully approved for a 20% hydrogen gas blend with no adjustment required, giving the installation a longer useful life as the UK gas grid transitions toward lower-carbon fuel blends. Smart Control Compatible Works natively with Ideal's Halo smart thermostat range and any OpenTherm-compatible control, plus weather compensation for load-matched, efficient running. Compact Cupboard Fit At just 278mm deep, the case fits inside a standard kitchen cupboard, with a minimum front clearance of just 5mm from the door (450mm needed with the door open for servicing). Easy Installer Access Fully serviceable from the front, with a single dual-purpose spark/detection electrode, push-fit PRV connection, and a colour-coded green filling loop handle for simple user self-management.

The C30's 30.3kW DHW output and 12.4 L/min flow rate makes it a good fit for homes with one or two bathrooms and moderate simultaneous hot water demand. Larger properties with multiple bathrooms or higher demand may be better served by the 35kW Logic Max Combi2 C35 variant. Do I need to register the boiler to get the 10-year warranty? Yes. The full 10-year parts and labour warranty is conditional on registering the boiler with Ideal Heating within 30 days of installation. Registration is normally completed online by the installer or homeowner once the commissioning is complete. Is this boiler compatible with smart thermostats? Yes. The C30 is compatible with Ideal's Halo range and any OpenTherm-enabled smart thermostat, allowing weather compensation and modulating control for improved efficiency over a standard on/off room thermostat. Does it fit in a standard kitchen cupboard? Yes. At 700 × 395 × 278mm the C30 is designed for a compact cupboard installation. A minimum 5mm front clearance from the cupboard door is required day-to-day, but 450mm of clearance with the door open is needed to allow full front access for servicing. Can it run on LPG instead of mains gas? The C30 is supplied configured for natural gas (G20). An LPG conversion kit is available separately and must be fitted by a Gas Safe registered engineer qualified for LPG appliances. Who can install this boiler? Installation, commissioning and servicing must be carried out by a Gas Safe registered engineer, in line with UK Gas Safety (Installation and Use) Regulations and Building Regulations Part L.
