If your Ideal Heating Boiler isn't providing hot water, ensure that the system is on and the cylinder thermostat is calling for heat. If the problem continues, contact Ideal Customer Service or a Gas Safe Registered Engineer.
Why is there no central heating in my Ideal Heating LOGIC MAX SYSTEM2 S30 Boiler?
If your Ideal Heating Boiler isn't providing central heating, first ensure that the system is turned on. Then, check that the timer is on and the thermostat is set to a sufficient temperature. Verify the time settings on the programmer and adjust them if needed. If problems persist, it's recommended to contact a Gas Safe Registered Engineer.

The Ideal Logic Max System² is a high-efficiency condensing system boiler designed to provide central heating and hot water when connected to a separate hot water cylinder. It features a full sequence automatic spark ignition and fan-assisted combustion for reliable operation. Due to its high efficiency, the boiler produces condensate from the flue gases, which is drained through a plastic waste pipe at the base of the unit. A condensate 'plume' may also be visible at the flue terminal during operation.
The boiler's primary function is to heat water for central heating and domestic hot water systems. It operates by burning gas, and its output automatically adjusts to match the heat demand, leading to reduced gas consumption. The boiler is equipped with a control panel featuring hot keys, a central heating temperature knob, a boiler status display, and a burner on indicator.
To start the boiler, users need to switch on the electricity to the boiler and ensure all external controls, such as the programmer, room thermostat, and cylinder thermostat, are on. The boiler status display will show a "Boiler" symbol or "Tap and Radiator" symbols. Users then press the "Mode" button until "Ready" or "On" is displayed. The central heating temperature knob can be adjusted to set the desired temperature, typically 80°C for the boiler symbol or 30°C for tap and radiator symbols.
The boiler offers different operation modes:
Weather Compensation: If fitted, this feature allows the central heating temperature knob to control room temperature. Turning the knob clockwise increases room temperature, and anti-clockwise decreases it. Once the desired setting is achieved, the system automatically adjusts to maintain the room temperature based on outside weather conditions.
Boiler Frost Protection: The boiler has built-in frost protection that activates if the water temperature inside the boiler falls below 5°C, preventing freezing. This feature operates in all modes, provided the power supply is on. For system-wide frost protection, if a system frost thermostat is installed, the boiler must be set in winter mode with "Ready" or "On" displayed. If no system frost protection is available and frost is likely during a short absence, it's recommended to leave heating controls on at a reduced temperature. For longer absences, the entire system should be drained.
Control of Water Temperature: The central heating radiator temperature can be adjusted from 30°C (minimum) to 80°C (maximum) using the central heating temperature knob. For efficient operation, the leaf symbol on the temperature control knob indicates an economy setting.
Boiler Restart: In case of a fault, the boiler may display an "Ignition Lockout" message. Users can press the "Restart" button to repeat the ignition sequence. If the boiler still fails to light, a registered gas installer should be consulted.
System Water Pressure: The system pressure gauge indicates the central heating system pressure. If the pressure falls below 0.3 bar, the boiler will not operate. If the pressure consistently drops, it may indicate a water leak, and the system should be re-pressurised or a Gas Safe Registered Engineer contacted.
Condensate Drain: The appliance is fitted with a siphonic condensate trap system to reduce the risk of freezing. If the condensate pipe freezes, users can apply a hot water bottle, microwaveable heat pack, or warm damp cloth to the frozen area. Warm water (not boiling) can also be poured onto the pipe. Once the blockage is removed, the appliance can be restarted. To prevent freezing during cold weather, it's recommended to set the central heating temperature knob to "MAX" and run the heating continuously, turning the room thermostat down to 15°C overnight or when unoccupied.
Troubleshooting: The user guide provides a troubleshooting section with flowcharts for "No Hot Water," "No Central Heating," and "No Hot Water or Central Heating." It guides users through checks like ensuring mains power is on, verifying boiler display status, and checking timer and thermostat settings. Fault messages, such as "Overheat Lockout," "Ignition Lockout," "Outside Sensor Fault," "Room Thermostat Fault," "Gas Valve Fault," "Return Thermistor Fault," "Spare PCB Not Set," "Blocked Flue/Condensate," "Flame Loss," "Fan Fault," "No Water Flow," "Too Many Restarts," "PCB Fault," "Pump Rotor Blocked," "Flame On Before Gas On," "Low Mains Voltage," "Pump Dry Run," "Flow Thermistor Fault," and "Low Water Pressure," are displayed on the boiler screen, often with instructions for initial user actions or advice to contact an installer.
Cleaning: For normal cleaning, the boiler casing can be dusted with a dry cloth. Stubborn marks and stains can be wiped with a damp cloth and then finished with a dry cloth. Abrasive cleaning materials should not be used.
Servicing: The frequency of servicing depends on installation conditions and usage, but it should be carried out at least annually by a Gas Safe Registered Engineer. The boiler will display a "Service Due" message after one year of installation, which can be cleared by pressing "Restart."
Safety: The appliance must be earthed, and the electricity supply should be 230 V ~ 50 Hz with a 3A fuse. It is crucial that the casing is correctly fitted and forms an adequate seal during operation. If the boiler is installed in a compartment, it must not be used for storage. If a fault is suspected, the boiler must not be used until a Gas Safe Registered Engineer has corrected the fault. No sealed components should be used incorrectly or tampered with. Only spare parts conforming to safety and performance specifications should be used for replacements. Reconditioned or copy parts not authorised by Ideal Heating should not be used.
The appliance can be used by children aged 8 and above, as well as persons with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, provided they are supervised or instructed on safe use and understand the hazards involved. Children should not play with the appliance, and cleaning or user maintenance should not be performed by children without supervision.
In case of a gas leak or suspected fault, the National Gas Emergency Service should be contacted immediately. All naked flames must be extinguished, electrical switches not operated, and all windows and doors opened.
