Real SwiftHeat UK project
Assessment first. A considered replacement.
Glyncoch, Pontypridd · Completed
A Baxi Duo-Tec with more than twelve years of service assessed as beyond economical repair, then replaced with a Viessmann Vitodens Classic 28kW combi.
The homeowner’s need
A decision based on condition, not age alone.
The existing Baxi Duo-Tec had provided more than twelve years of service. Following a professional assessment, it was considered beyond economical repair.
The homeowner chose a Viessmann Vitodens Classic 28kW combi replacement. SwiftHeat UK completed the installation on 3 September 2026, including system protection, commissioning, safety checks and certification.
The completed installation.
The replacement boiler
A Viessmann Vitodens Classic 28kW combi was installed to provide central heating and hot water on demand.
System protection
ADEY MagnaClean magnetic filtration was included to help collect magnetic debris circulating in the heating system.
Checks and documentation
The project included professional commissioning and safety checks, together with Gas Safe and Building Regulations certification.
Assess First. Recommend Second.
Understand the options before replacing.
Boiler age is one part of the picture. Condition, reliability, repair history, parts availability and the cost of further repairs all help inform whether repair or replacement makes sense.
For this homeowner, the assessment identified replacement as the appropriate route. For another home, a safe and cost-effective repair may remain a suitable option. A discussion and assessment help establish the next step.
