Alpha Heating Innovation has installed boilers throughout a high-end residential development of 55 apartments in Edinburgh. Harbour Green offers apartments with one, two and three bedrooms and is on the seafront at Portobello, less than three miles from the city centre.
Improving the energy performance of the UK’s buildings remains one of the greatest challenges facing the building-services industry. With today’s boilers capable of achieving the required increased reliability and high thermal efficiency, the goal now is to engineer for maximum efficiencies, says James Porter of Remeha.
According to the Carbon Trust, heating and hot water can account for as much as 60% of total energy use in a commercial building. With energy saving high on the agenda, replacing an old, inefficient boiler may seem an easy fix, but Neville Small of Potterton Commercial explains why careful consideration should be given to the replacement and points to the benefits of boiler cascades.
Hamworthy Heating’s Stratton mk2 wall-hung boiler has the smallest output in the stainless-steel family and is described as a great match for restricted-space plant rooms. These boilers have been designed to assist customers in refurbishment projects. The robust qualities of stainless steel make it very tolerant of older heating circuits and resistant to corrosion for easy maintenance and a long life.
Selecting energy-efficient boiler plant is just the first step in efficiency. How it is controlled through its life is just as important. Kevin Stones of Hoval illustrates this principle with reference to heating systems served by cascade boiler installations.
