EXHAUSTO EBC20 boiler controller installed at new Dakota hotel
The boiler house of the new £15 million 132-room Dakota Hotel in South Queensferry, Scotland, has been equipped with the recently announced EXHAUSTO EBC 20 boiler controller and an EXHAUSTO chimney fan system to provide controlled draught in the hotel’s SFL Nova chimney system./EBC20.jpg)
The distinctively black-clad, state-of-the-art hotel has been built by Ken McCulloch, the Malmaison Hotels founder, and his business partner David Coulthard, the Formula One racing driver, as the latest addition to the Dakota portfolio of three luxury budget-priced Dakota hotels in Britain – the first, in Nottingham, opened in July 2004.

The Scottish EXHAUSTO Technology Centre, JRF Chimney Specialists Ltd of Glenrothes worked with RSP Consulting Engineers LLP to design a chimney layout for the twin boiler installation that would suit the local conditions and site requirements. JRF Chimney Specialists designed the SFL Nova SM chimney system, a Rockwool-insulated twin-wall stainless steel system, to incorporate an EXHAUSTO RSV chimney fan system, thereby ensuring a controlled draught and making possible a flue system that best utilised the space available on the site.
The boiler installation consists of two Hamworthy Wessex type M440 boilers with maximum output of 440 kw, eachcontrolled by the new EXHAUSTO EBC 20 boiler controller. The EBC20 is designed to ensure that the draught in the flue system is constantly correct to achieve the greatest fuel efficiency and safety, regardless of how many boilers are connected to the flue or of external weather or environmental conditions. Many people do not realise the dramatic effect that adverse weather can have on flue efficiency, and therefore on boiler fuel costs – the chimney automation system eliminates this costly variable and also matches the flue draught to the requirements of the boiler system at all times. The installation at the Dakota Hotel in South Queensferry is the first EBC20 installation to be completed in the UK.
When designing the chimney system, it was essential that the highest possible utilisation of the available space was achieved. According to JRF Chimney Specialists, if a conventional flue had been installed, the diameter of the chimney would have been 500mm. By using the controlled draught achieved by the EXHAUSTO chimney fan system and EBC20 controller, it was possible to design the flue to run horizontally above the boilers before rising vertically for 16 metres as a vertical flue of only 350mm diameter. This achieved a major saving of space, greater fuel efficiency and immunity for the chimney system from the sometimes adverse weather conditions of the site beside the Firth of Forth.
