Oil Boiler Installation
We design and install energy-efficient oil-fired boilers tailored to rural properties without gas access. Our process ensures minimal mess and disruption, with systems optimised for high efficiency and cost-effectiveness. Clients receive expert advice on selecting the right boiler type, including condensing, combi, or system boilers, to suit their home's heating needs.
Oil Boiler Servicing
Annual servicing maintains boiler efficiency and longevity, reducing the risk of breakdowns. Our engineers inspect components, address wear and tear, and ensure systems operate at peak performance. Regular maintenance helps prevent costly repairs and sustains the boiler's 97% efficiency rating when serviced annually.
Condensing Boilers
Condensing boilers capture and reuse heat from flue gases, achieving up to 97% efficiency. Ideal for reducing energy bills, these boilers are installed with minimal disruption. We recommend annual servicing to maintain performance and ensure compliance with environmental standards, providing long-term cost savings for homeowners.
Combi Boilers
Combi boilers provide on-demand hot water without a storage tank, saving space in smaller homes. We assess property size to determine suitability, ensuring efficient hot water delivery. Installation includes programmable controls for heating and water, optimising energy use while maintaining comfort.
System Boiler Installation
System boilers operate on sealed pressurised systems, eliminating roof tanks and frost risks. We install these systems with thermostatic controls for precise temperature management. Ideal for properties seeking reliable heating, our installations include programmable timers and energy-efficient components to reduce running costs.
