CALORIFIERS

A TOTAL CHOICE
IN COMMERCIAL
HOT WATER PRODUCTS

Albion can design and manufacture a large range of calorifiers for commercial and industrial use. These products are made to appropriate standards, and in line with Albion's policy, the range is being developed constantly.
Albion has a long history of trading in these products and over the years has been involved in many prestigious developments. The company has supplied the hot water needs of customers as diverse as Shell, BBC, NatWest Bank, the Royal Courts of Justice, Horse Guard Barracks at Westminster as well as the supply of calorifiers to HM Prisons, schools, hotels, leisure centres, golf clubs -in fact wherever there is a demand for hot water, Albion has been able to supply it.
Recently the company has diversified into marine calorifiers and hot water provision for light commercial vehicles.
Albion offers a full design service and is able to respond promptly to specifiers, contractors and engineers. Skilled operatives ensure that the final product meets the customer's specification. The company has a policy of product development and has a flexible and helpful approach to individual customer requirements.

SIZING FOR HOT WATER DEMAND

METHOD OF ASSESSING RECOVERY/STORAGE RELATIONSHIPS FOR HOT WATER STORAGE

When sizing hot water storage calorifiers, it is important to determine not only the correct size but also the correct relationship between recovery and storage to enable the most efficient selection of plant to be made. If too high a storage volume is selected and the recovery rate determined as a time function of the volume, then not only is the vessel and heat exchanger oversized but likewise the primary generating plant, pumps, pipework and controls.
The effect of oversizing will vary depending on the degree and type of building , but where the domestic hot water load represents a substantial proportion of the total heating load, unnecessary expenditure, both in capital and running costs, is involved.
Where inadequate storage and recovery are provided, the system will not meet the user requirements, with the result that costly modifications may be necessary when the building is occupied and the engineering services in daily use.
Whatever the building under construction, a pattern of hot water usage can be projected, the actual usage being largely a function of the building population and the types of activity that takes place within.
In determining the pattern of usage, it is important to differentiate between the maximum daily demand and the average daily demand, so that the implications of the system not meeting the demands made upon it can be recognised, and the maximum requirements designed for where necessary.
To project the demand pattern over the operating period an hour by hour analysis of hot water usage should be made. Taking into account the building population, the level and type of activity and all other factors which affect hot water demand, a quantitive assessment of hourly uage should be tabulated for every hour of the operating period.
For offices and schools, a continuous 12 hour operating period may be sufficient, but for other buildings such as hospitals and factories a 24 hour operating period may be neceesary.
