Case Study: Boherbue Parish Hall, Co Cork
CALOR POWERS PARISH HALL 路 Refurbished parish hall at the heart of the community. 路 Challenging installation calling for technical expertise. 路 Modern, controllable system achieves cost savings.
Boherbue Parish Hall, the focus of its local community, opted for a modern, efficient heating system during its recent refurbishment.
6 Mark Eire plaque heaters provide the heating for the main hall.
Boherbue Parish Hall is home to a vibrant network of community groups, including the Boherbue and District Development Council. The building itself comprises of a main hall and several meeting rooms. Originally built in 1952/53 and opened on May 30th, 1954 by Dr Moynihan, Bishop of Kerry, it has for the past 58 years been in constant use for all sorts of local events. In 2011 the hall committee took the decision to replace the outdated and unreliable heating system and tasked Committee Members Marie Casey and John Murphy to work with the appointed builder, Alan Lynch Construction, to explore the available options. From the earliest discussions it was clear that the project presented a number of technical challenges – low ceilings limited the scope for heating equipment and ventilation regulations imposed further constraints. Added to this was how to heat the rooms that were being used at a specific time rather than heating the entire building. The team decided to enlist the expertise of Mark Eire, one of the country’s leading suppliers of heating systems, and the firm’s Area Manager Michael Keane joined the team.

Michael quickly assessed the options based on the brief. The Committee agreed that oil and electricity would prove expensive and in particular, oil fired equipment would require more frequent servicing. Key requirements for the new system were: • An efficient and cost-effective system • Equipment that was reliable and easy to control • Compatibility with the constraints of the rooms • Safety features that reflected the layout of the hall and those using it. Michael’s solution was the installation of a Calor LPG powered system using Mark plaque heaters. These could be used to provide instant heat in confined areas that were unsuitable for radiant tube heaters or ventilation fan based heaters. The instant heat generated combines comfort and efficiency, with Mark’s plaque heaters providing first class safety features. Plaque heaters offer outstanding levels of economy and efficiency. The are best suited for installation in buildings with a medium to high ceiling height. The gas-air mixture which is fed to the ceramic tiles of a plaque heater play a crucial role in its efficiency.
Better gas-air mixture means better heat delivery. The gas-air mixture burns in minute ducts just below the outer surface of the ceramic tile. The result is that the ceramic and its heat is instantly transmitted in the form of infrared heat. Because the heat exchange is so rapid, combustion is ‘cold’. That is, heat exchange occurs so quickly that the NOX emissions remain insignificant. Nitrogen oxides (NOx) are formed during the combustion of fossil fuels and are mainly nitric oxide (NO) and nitrogen dioxide (NO2), together commonly referred to as NOX. The main source of NOX emissions is the combustion of fuels in motor vehicles, residential and commercial heaters, industrial and electrical-utility boilers and engines, and other equipment. Calor LPG powered radiant heaters produce less harmful emissions compared with oil powered heating installations.
Each plaque heater has its own individual ‘cut off’.

Mark PSW ceiling heaters are highly efficient and quiet.
• At 40DB maximum, the units have low running noise. In addition to the plaque heaters used in the main hall, Mark ceiling heaters are employed in the meeting rooms and are highly efficient thanks to the crossed exchanger principal where the burner produces a horizontal flame that crosses a vertical air flow produced by the convection fan. The system is very quiet, which was of particular importance as the rooms are used for meetings as well as for social gatherings. A coin operated meter ensures that the premises are heated only when in use – providing flexibility and control, and clear cost savings compared to the previous system.

The entire installation is powered by two 450Ltr Calor mini-bulk tanks, which are unobtrusive, taking up minimal space, while providing enough capacity to power all of the hall’s heating requirements. An added benefit from this option was that the hall would see further cost savings through bulk gas prices. Both mini bulk tanks are regularly refilled by the country’s largest LPG supplier – ensuring a reliable supply.
Calor provides the optimum heating solution The combination of Calor’s expertise in the supply of LPG coupled with one of the country’s leading space heating specialists – ‘ Mark Eire’ has resulted in a tailored energy solution that is modern, efficient and economical. The new space heating system at Boherbue Parish Hall illustrates clearly how energy management can be achieved on an on-going basis. The use of a coin meter in the hall is particularly beneficial for the energy cost management of buildings of this nature, which have an irregular usage pattern and are used by a range of organisations. Calor LPG is a versatile fuel and can work with a range of energy-efficient appliances and low carbon technologies for additional savings. The committee at Boherbue are delighted with their new heating system and the energy savings it provides.
