A complete, factory-matched heating package pairing the Ideal Logic Max System2 30kW condensing gas system boiler with the Ideal Standard Horizontal Flue Kit and the 300L System Ready pre-plumbed indirect unvented cylinder. The boiler arrives fully assembled with its own circulating pump, pressure gauge, pressure relief valve and expansion vessel, while the cylinder is factory pre-plumbed with its full Part G3 safety kit, manifold, zone valve and wiring junction box — reducing the on-site work to connecting pipework, fitting the flue and wiring the system together. Supplied as a natural gas package, ready to run on up to a 20% hydrogen blend with no adjustment.

🔴 Gas Safe Registered Installation Required
This boiler must be installed, commissioned and serviced by a Gas Safe Registered engineer, in accordance with the Gas Safety (Installation and Use) Regulations and Building Regulations Part L. The cylinder is an unvented hot water storage system covered by Part G3 and must be installed by a G3-qualified competent person — the safety devices on both the boiler and cylinder must never be removed or bypassed.
🟡 Bundle Components Are Supplied Separately, Not Pre-Assembled
This listing bundles three separate factory items — the boiler, the horizontal flue kit and the pre-plumbed cylinder — under one order. They are not physically joined; your installer will site, pipe and wire them together on installation day following each manufacturer's own instructions.
🟢 System Ready Cylinder Cuts On-Site Plumbing Time
The 300L cylinder in this bundle is the System Ready pre-plumbed version — the combination inlet group, relief valves, dual control/overheat thermostat, zone valve and wiring junction box are factory-fitted and tested, so only the immersion heater needs fitting on site.
Condensing System Boiler, Fully Assembled
The Logic Max System2 30kW ships complete with its circulating pump, pressure gauge, pressure relief valve and CH expansion vessel already fitted, plus the Ideal System Filter supplied in the box — reducing the parts an installer needs to source separately.
Matched Horizontal Flue Kit Included
The bundle includes the Ideal Standard Horizontal Flue Kit (60/100mm, 600mm length), suitable for through-wall termination to the rear, left or right of the boiler — sized correctly for the Logic Max System2 range without needing a separate flue order.
Hydrogen-Blend Ready
The boiler is certified to run on up to a 20% hydrogen/natural gas blend with no technical adjustment required, giving some future-proofing as the UK gas grid composition evolves.
Pre-Plumbed Cylinder Reduces Install Time
The 300L System Ready cylinder's indirect coil is rated at 25 kW, comfortably within the 30kW boiler's condensing output range, giving a full heat-up time from 15°C to 60°C of around 38 minutes.
Full Diagnostic Display & OpenTherm Compatible
The boiler's colour display gives detailed status and fault-finding information during commissioning and servicing, and the control platform is OpenTherm compatible for use with modulating room thermostats and smart controls.
Duplex Stainless Steel Cylinder Vessel
The 300L cylinder shell is manufactured in high-grade duplex stainless steel with HCFC-free foam insulation, and carries a manufacturer's 25-year warranty on the vessel itself (subject to T&Cs).

Is the 30kW boiler powerful enough for the 300L cylinder?
Yes. The 300L cylinder's primary coil is rated at 25 kW, which sits comfortably within the Logic Max System2 30kW's condensing output range, giving a full cylinder heat-up from 15°C to 60°C of approximately 38 minutes.
Does this bundle include the vertical flue option instead?
No — this listing includes the Standard Horizontal Flue Kit (MPN 208171), 60/100mm diameter, 600mm length, for through-wall termination. If your installation requires a vertical or extended flue run, contact us for the correct alternative kit.
Can the components be delivered and installed separately?
The boiler, flue kit and cylinder are supplied as separate factory items bundled under one order for convenience and to ensure compatible components are matched together — your installer will site and connect each part individually rather than receiving a single pre-assembled unit.
Is this boiler suitable for a hydrogen-blended gas supply?
Yes. The Logic Max System2 range is certified to run on natural gas blended with up to 20% hydrogen without any technical adjustment, in line with current UK gas grid trials.
What's included with the cylinder that isn't included with a standard Ideal Pro cylinder?
The System Ready cylinder in this bundle comes with its full G3 safety kit factory-fitted and tested — combination inlet group, relief valves, thermostats, motorised zone valve, manifold and wiring junction box — rather than supplied as loose components for the installer to plumb in.
Does the boiler need a Gas Safe engineer to install?
Yes. Installation, commissioning and servicing must be carried out by a Gas Safe Registered engineer, and the cylinder must be installed by a competent person qualified in unvented hot water systems (G3), in accordance with the relevant Building Regulations.
