About Ideal Boilers

Why We Recommend Ideal Boilers

Ideal Boilers is one of the UK's oldest boiler manufacturers, based in Hull and manufacturing domestically since 1906. Their Logic range — particularly the Logic Plus and Logic Max — is one of the most installed combi boiler series in the UK market, prized for straightforward installation, competitive pricing and good reliability across their product life.

The Logic Max is Ideal's current flagship combi, offering 7 years manufacturer warranty when installed by an Ideal registered installer, ErP A-rated efficiency and a compact footprint suitable for London flats and smaller properties. For larger homes, the Logic Heat system boiler range is a popular mid-range option pairing well with unvented cylinders.

Ideal parts are widely available, making out-of-warranty repairs cost-effective compared to some premium brands. Anmol Boilers engineers are experienced with the full Ideal Logic range and carry common Ideal spare parts on their vans for same-visit repairs.

Fault Codes

Common Ideal Boilers Error Codes

See your boiler displaying an error code? Here is what it means and what to do.

F1Ignition failure / no flame detected

Check gas supply is on. Could be a faulty ignition electrode, lead, gas valve or PCB. Engineer diagnosis required.

F2Flame failure — flame lost during operation

Flame sensor, gas valve or intermittent gas pressure issue. Do not keep resetting — call an engineer.

L2Fan fault — fan not reaching correct speed

Fan replacement or PCB issue. Boiler will not light safely without correct fan operation.

F4Flow temperature sensor fault

NTC thermistor failure on the flow pipe. Inexpensive part — usually a same-visit repair.

F5Return temperature sensor fault

NTC thermistor failure on the return pipe. As above — inexpensive and commonly held in stock.

L1Overheat — safety thermostat tripped

Similar to Worcester E9. Check pressure and pump operation. Do not repeatedly reset without investigation.

Fault code not listed, or boiler keeps locking out?

Do not keep resetting a boiler that repeatedly locks out — this can mask a developing fault and cause damage. Call us and describe what you see; we can often diagnose over the phone.

FAQs

Ideal Boilers Questions Answered

How long is the warranty on an Ideal Logic Max boiler?+
With an Ideal registered installer, the Logic Max carries a 7-year parts and labour manufacturer warranty. With a non-registered Gas Safe engineer, the standard warranty is 2 years. We register all Logic Max installations directly with Ideal Boilers at the time of installation.
Is the Ideal Logic a good boiler for a London flat?+
Yes — the Logic Max Combi is one of the most popular choices for London flats and smaller properties. Its compact dimensions (720 × 390 × 280mm) fit standard kitchen cupboards, it is quiet in operation, and its ErP A efficiency rating helps keep gas bills down. The 7-year warranty with a registered installer gives good long-term peace of mind.
My Ideal boiler is showing an F1 fault code — what does this mean?+
F1 on an Ideal boiler indicates an ignition failure — the boiler attempted to light but no flame was detected. First check that the gas supply to your property is on (check a gas hob if you have one). If gas is present, the fault is likely a faulty ignition electrode, ignition lead or gas valve and will require a Gas Safe engineer to diagnose and repair.
How does the Ideal Logic compare to a Worcester Bosch Greenstar?+
The Worcester Bosch Greenstar is generally considered the premium choice, with a longer track record of reliability and a stronger extended warranty (up to 10 years vs 7 years for Ideal). The Ideal Logic is a solid mid-range alternative at a lower installed price, with good parts availability and a simpler design that makes it cost-effective to repair. For most London properties, both are excellent choices — the right decision depends on budget and how long you plan to stay in the property.
Can you service an Ideal boiler that was installed by another company?+
Yes. Any Gas Safe registered engineer can service an Ideal boiler. Annual servicing with any Gas Safe registered engineer keeps your manufacturer warranty valid. We issue a full service record on completion.
