Services
Boiler Installation
We install new boilers from leading manufacturers including Viessmann and Ideal across South Wales. Our Gas Safe Registered engineers provide full system replacements with options for LPG boilers and 12-year extended warranties on selected models. All installations include safety checks, compliance certificates, and post-installation guidance to ensure optimal performance and energy efficiency.
Boiler Servicing
Professional boiler servicing maintains safety, efficiency, and warranty validity. Our engineers conduct comprehensive checks including flue analysis, pressure testing, and component inspections. We identify potential issues before they become emergencies while providing landlords with required safety certifications. Regular maintenance reduces energy bills by up to 15% through improved system efficiency.
Central Heating Installation
Complete central heating system installations include boiler replacement, radiator upgrades, and smart thermostat integration. We design energy-efficient systems tailored to property size and occupancy needs. Our installations incorporate modern controls like Nest thermostats for remote temperature management, helping homeowners reduce energy consumption while maintaining comfort.
Powerflushing
Our powerflushing service removes sludge and limescale buildup from central heating systems. Using high-velocity water flow and specialist chemicals, we restore system efficiency, eliminate cold spots in radiators, and extend boiler lifespan. The process includes inhibitor treatment to prevent future corrosion, typically completing full system rejuvenation within a single working day.
Unvented Cylinders
We install unvented hot water cylinders that deliver mains-pressure hot water to multiple outlets simultaneously. These systems eliminate the need for loft tanks while providing consistent flow rates for showers and baths. Our OFTEC-registered engineers ensure compliance with building regulations, including safety valve installations and pressure management systems.
