What is a Registered Gas Safe Installer? – VIVA Training (2025-01-14)

A Gas Safe registered engineer is legally authorized to work on gas appliances, including boilers, ensuring safe installation and compliance with regulations. They must ensure the boiler is installed safely and securely.

Key steps include:

• Power and gas isolation to protect existing systems.
• Removal of the old boiler and safe disposal of components.
• Flushing the heating circuit to eliminate debris and prevent blockages.
• Fitting magnetic filters to extend system longevity.
• Pressure testing and commissioning the new boiler.

Boiler efficiency directly influences household energy consumption, cost savings, and carbon emissions, making it a pivotal factor in both financial and environmental considerations.

Condensing boilers recover latent heat from flue gases by cooling them below the dew point, which captures water vapour heat that would otherwise escape. This mechanism routinely achieves efficiencies above 90%, reducing fuel usage and emissions, and setting the stage for understanding efficiency ratings.

Condensing Boiler | AHRI (2024-10-22)

Condensing boilers can achieve high efficiencies, with a typical thermal efficiency of 92-95%, by recovering heat from flue gases. Modern condensing boilers are labelled between 92-94% efficient ErP, aka A-rated.

The ErP (Energy Related Products) label and SEDBUK (Seasonal Efficiency of Domestic Boilers in the UK) ratings measure annualised efficiency under standard conditions. A-rated boilers like most Worcester Bosch and Ideal models exceed 92% seasonal efficiency, translating into lower running costs and a smaller carbon footprint.

A Complete Guide to ERPs and Boiler Ratings – BOXT (2020-09-05)

The ErP (Energy-related Products) label and SEDBUK (Seasonal Efficiency of Domestic Boilers in the UK) ratings measure boiler efficiency. All new gas boilers in the UK are A-rated, which means they’re highly efficient.

Both brands achieve A-rated efficiencies and Which? Best Buy awards; Ideal excels in value pricing and compact design, while Worcester Bosch leads in advanced features and extended warranties.
