Frequently Asked Questions - MainEco Heat 24 Baxi

What should I do if the boiler does not light?

First check that the gas supply is on and the timer/thermostat are calling for heat. If the boiler still fails to light, press the RESET button for at least 5 seconds. If it does not reset, contact your installer or Baxi Customer Support.

How do I interpret the status light on the control panel?

A steady green light that blinks off briefly every 7 seconds indicates normal operation. A flashing orange light means the boiler is responding to a heat demand. A flashing green light indicates a warning; the boiler is trying to resolve an issue. A flashing red light means a lock-out fault; press RESET. A continuous red light requires contacting support.

What does the number of flashes on the status light mean?

The number of flashes indicates specific fault codes. For example, 1 flash green = temperature protection; 1 flash red = sensor error. Refer to the troubleshooting section in the user manual for full details.

How often should I service the boiler to maintain the warranty?

An annual service must be carried out by a Gas Safe registered engineer or Baxi Customer Support. The service record in the Benchmark Service Record must be completed.

What should I do if the boiler water pressure is too low?

For sealed systems, the recommended pressure is between 1.0 and 1.5 bar (cold). If it drops below 0.7 bar, top up using the filling loop (your installer can advise). If you need to top up frequently, there may be a leak.

Can I install the boiler myself?

No. Installation must be carried out by a Gas Safe registered installer in Great Britain, or a competent person in Ireland. Incorrect installation can invalidate the warranty and be dangerous.

How do I set the boiler flow temperature?

Turn the rotary knob on the control panel: clockwise to increase, anti-clockwise to decrease. The temperature range is 30°C to 80°C. For domestic hot water, set it higher than the cylinder thermostat.

What should I do if I smell gas?

Immediately turn off the gas supply at the meter, open windows and doors, do not operate electrical switches or phones, extinguish naked flames, and call the National Gas Emergency Service on 0800 111 999.

Where can I find the serial number of the boiler?

The serial number is on the information label under the boiler, accessible via the slide-out flap at the lower left. Do not remove or cover this label.

What is covered under the standard warranty?

The 2-year warranty covers parts and labour for in-warranty repairs. It requires the Benchmark Checklist to be completed, the warranty registered with Baxi, and annual servicing. For full terms, visit www.baxi.co.uk/terms.

11 Environmental

11.1 Energy Saving

Tips on saving energy:

▶ Do not cover radiators. Do not hang curtains in front of radiators.
▶ Install reflective panels behind the radiators to prevent heat losses.
▶ Insulate the pipes in rooms that are not heated (cellars and lofts).
▶ Install loft insulation & double glazing.
▶ Use draught excluders where necessary.
▶ Upgrade any older external controls.
▶ Turn down room thermostats by 1°C
▶ Turn off radiators in rooms not in use.
▶ Do not run hot (or cold) water pointlessly.
▶ Fit a water-saving shower head to save up to 40 % energy.
▶ Take showers rather than baths. A bath consumes twice as much water and energy.

11.2 Room Thermostats and Settings

Various models of room thermostats are available. The thermostat type and setting affect the total energy consumption.

A few tips:

▶ Fully opening or closing thermostatic radiator valves result in unwanted temperature fluctuations. Turn the thermostat knob or valve higher or lower in small steps.
▶ Lower the thermostat to approximately 20° C. This reduces heating costs and energy consumption.
▶ When rooms are to be aired, lower the thermostat well in advance.
▶ When setting thermostats or programmers take account of days when nobody will be in and of holidays.
