Reliable, Friendly, Professional Plumbing Services
At DD Oil Boiler Service & Spares Ltd, we take pride in being specialists in wall hung combis, Oil Fired Condensing Boilers of superior quality. Our business was founded by Darran and Jake, who took over the company in April 2019 with the aim of providing exceptional products and services to our customers. Upon taking over the business, we decided to temporarily suspend the manufacturing side of the business to ensure that our boilers meet the highest standards.
We pride ourselves on our excellent customer service and our spares department is the most efficient it has ever been, with a large stock of all components for boilers going back 20 years, ensuring that most orders can leave on a next-day service. Our servicing and maintenance team are highly trained in not only Grandee products but all other oil-fired boilers and are more available than ever before to satisfy customers' needs.
We are committed to providing our customers with the best possible service, which is reflected in our technical helpline being accessible from 8-5 Monday to Friday on 0121 454 2244. If you need any advice or help in relation to any Grandee or Heating World appliance, our technical team is here to assist you.
Our range of products includes medium to large boilers, including our Grandee 15/22's and 23/28's, which are designed to meet the needs of medium to large properties. Our 15/22 boilers are suitable for properties up to 22KW, while our 23/28 boilers are designed for larger properties with an increased output.
We offer a range of boiler options, including our Standard Boiler, System Boiler, and Combi Boiler. Our boilers are designed to be easy to install, simple to use, and economical to run. Our combi boilers only heat water when a hot tap or shower is turned on, ensuring maximum efficiency.
We understand that space can be a limiting factor in many homes, which is why our boilers are designed to be wall hung, making them ideal for installation in garages or other areas with limited floor space.
At DD Oil Boiler Service & Spares Ltd, we take pride in the design and manufacturing of our boilers. Our boilers have been designed and manufactured specifically with the installer and engineer in mind, making installation and servicing a simple and straightforward process.
Our fluing options include horizontal balanced flue and vertical convention flue options, and we offer a two-year parts and labour warranty on all our boilers, with an additional three-year warranty on the primary heat exchanger.
