Professional. Experienced. Helpful.

A well-designed heating system ensures that a building remains comfortable throughout the year, no matter the weather conditions, so a professional design service is essential for any building project, whether it is a commercial or residential property.

D&O’s in-house Design and Specification Team will take into account a range of factors when creating their designs, including the size of the building, the number of rooms, and the preferred heating method. Using this information they will create a bespoke heating solution that is tailored to the specific needs of any project. They will advise on the most appropriate heating method, saving money and reducing the environmental impact of builds.

With extensive experience in products including boilers, air source heat pumps, hot water cylinders, solar panels, underfloor heating, mechanical ventilation and heat recovery plus much more D&O’s Design Team is here to help.

It's what we DO.
