What freeze protection is recommended for Riello condensing boilers?

For freeze protection, use only propylene glycol with scale inhibitors at a maximum concentration of 50%. The frost protection and inhibitor level should be checked annually during scheduled maintenance.

How does boiler frost protection work on Riello condensing boilers?

Riello condensing boilers have built-in frost protection that activates when the water temperature drops below approximately 5°C. The boiler automatically heats the water to around 10°C, then switches off. This cycle repeats as needed to prevent freezing. Note that this only protects the boiler itself - external pipework still requires separate insulation.

How often should a Riello condensing boiler be serviced?

Riello condensing boilers require annual maintenance by a qualified Gas Safe registered engineer. The heat exchanger should be inspected after 2,500 hours of operation or at least once a year.
