Boiler Installation
We install modern, energy-efficient boilers from leading manufacturers including Viessmann and Ideal. Our Gas Safe engineers handle complete system replacements, LPG boiler installations, and provide 12-year extended warranties on select models. Every installation includes safety checks, efficiency testing, and customer guidance on operation and maintenance. Our team ensures minimal disruption while delivering long-term heating solutions tailored to property requirements.
Boiler Servicing
Our comprehensive boiler services maintain system efficiency and safety through component inspections, flue checks, pressure adjustments, and carbon monoxide testing. We follow manufacturer guidelines to preserve warranties while identifying potential issues before breakdowns occur. Landlords receive documentation meeting legal requirements, and homeowners benefit from energy-saving optimizations. All services include post-service verification and maintenance advice.
Central Heating
We design and install complete central heating systems featuring modern radiators, smart controls, and underfloor heating solutions. Our engineers optimize system layouts for energy efficiency while integrating smart thermostat technology for remote temperature management. We also perform system upgrades, powerflushing, and radiator replacements to enhance performance across residential properties in South Wales.
Smart Thermostats
We install and configure smart thermostat systems from Hive and Nest, enabling remote heating control via smartphone apps. Our engineers demonstrate usage features, optimize scheduling settings, and ensure compatibility with existing boiler systems. These installations help reduce energy consumption while providing precise temperature management for improved home comfort and cost savings.
Powerflushing
Our powerflushing service removes sludge and limescale buildup from central heating systems using high-velocity water flow and specialized chemicals. This process restores system efficiency, extends boiler lifespan, and improves radiator performance. We include corrosion inhibitor treatments to prevent future deposits, typically completing the process within one working day while maintaining household comfort during the procedure.
