How do I switch my Beretta boiler to summer mode for hot water only?

Beretta boilers have a mode selector (often labelled Winter/Summer or with sun/snowflake symbols) on the control panel. Switch to Summer mode to deactivate central heating while keeping hot water available on demand. In this mode, the boiler remains in standby until you open a hot tap. This setting helps save energy during warmer months while maintaining hot water availability.

What is the difference between a combi and system boiler?

A combi (combination) boiler heats water directly from the mains on demand, providing instant hot water without needing a storage cylinder or cold water tank. A system boiler works with a separate hot water cylinder to store heated water, making it suitable for homes with higher hot water demand or multiple bathrooms. Combi boilers are more compact and suit smaller properties, while system boilers can supply hot water to multiple outlets simultaneously.

What does maintenance reminder code 91 mean on my Beretta boiler?

Code 91 is a maintenance alert that signals the need for servicing or cleaning of the primary heat exchanger. It appears based on hours accumulated in particular operating conditions, determined by the boiler's self-diagnosis system.

What does the A energy rating mean on my Beretta boiler?

The A energy rating indicates your boiler achieves at least 90% efficiency under the ErP (Energy related Products) Directive. In the UK, all new boilers must meet a minimum 92% efficiency (A-rated) under Boiler Plus legislation. An A-rated condensing boiler converts more fuel into usable heat, reducing energy bills and environmental impact compared to older G-rated boilers which operate below 70% efficiency.

How do I repressurise my Beretta boiler?

First, switch off your boiler and allow it to cool. Locate the filling loop (a flexible silver pipe with valves at either end) connected to the boiler's pipes. Open both valves so they're in line with the pipe, allowing cold mains water into the system. Watch the pressure gauge and close both valves when the pressure reaches 1.0-1.5 bar. Switch the boiler back on and reset any fault codes if necessary.
