Understanding Boiler Servicing & Repairs

Recognising when you require a boiler service versus a heating repair is vital. Boiler servicing, akin to a car’s MOT, is an annual check-up for safety, efficiency, and performance, including replacing specified parts as instructed by the manufacturer. Mainly, a boiler service is preventive, catching issues before a complete failure, the annual MOT for your boiler!

Boiler repairs, however, are required when a breakdown occurs and your boiler stops producing heating or hot water. Our standard boiler servicing and “Cosy Plan” service plan does not cover repairs or faulty boilers, focusing instead on preventive maintenance.

Property Type

The Worcester Bosch Greenstar 8000 is available from 30kw up to 50kw, making it a very versatile unit. For a better consideration of this boiler, the 40kw output means this boiler is good for homes of most sizes, especially for those with two bathrooms where plenty of hot water is required simultaneously.

Controlling Your heating

Choosing the proper heating controls for your boiler can often be confusing, but finding the right controls for your boiler, it allows you to take complete control of your heating system and never waste energy again.

As part of the Boiler Plus initiative, ‘smart’ Vaillant controls automate and optimise certain functions of your boiler, resulting in lower energy bills. At Warm and Cool, we recommend the Vaillant ‘Senso’ controls to ensure you always get the most out of your boiler at any time of the day without compromising on energy usage.
