CASE STUDY
EMAX 100 KW ENERGY CABIN SCHEME
Location :
Drimoleague, County Cork, Ireland
Project :
Fairfield nursing home heating scheme
Introduction: The Fairfield Nursing Home utilises an EMAX 100 kW Energy Cabin scheme, replacing
an aged 100 kW oil boiler, providing Central Heating and Hot Water to a building area
of 1200 m2 that accommodates the 40 residents and nursing staff at the home.
 The Energy Cabin is located at the rear of the
nursing home and the heat energy is distributed via
underground pipes to the 1200 m2 building accommodation area.
 The nursing home utilises an EMAX 100 kW Energy Cabin, consisting of a KWB USV 100 pellet fired
boiler with 24m2 of Thermal Solar collector panels.
 During the winter the 100 kW boiler is the primary source of heat to the Nursing home.
 During the summer months or when the heat
demand is reduced, water is primarily heated by the
24 m2 thermal solar panel with the boiler giving back
up to maintain the temperature.
 Fuel pellet consumption is reduced by approximately one quarter via utilisation of the solar panels,
so saving money.
 A 1500 litre water storage tank acts as a heat
reservoir to smooth out boiler stop/starts and provide
a constant supply of hot water.
 The wood fuel pellets are discharged by blow
wagon into a 13 tonne (23m3) storage container, adjacent to the boiler room.
 This size of store enables a more economic delivery amount.
 The pellets are automatically fed from the storage area to the boiler by a fully automatic screw feed
with 3 levels of safety feature to prevent any chance
of burn back into the store.
 The hot water return temperature is automatically controlled via a programmable controller as it
flows through the boiler.
 All energy cabins come fully piped up and wired
ready to connect to customer’s hot water and heating systems.
 The system can be remotely accessed and supported via engineers using a modem facility to ‘dial
in’ and check operation and status.
 The clean flue gases are extracted from the boiler
through a stainless steel chimney.
 The ash is automatically removed from the combustion chamber to an ash box via a worn conveyer.
 The boilers are designed and controlled to ensure very clean combustion of the fuel.
 The ash is compressed enabling greater volumes
to be stored and emptying reduced to every 2-6 weeks.
 An invisible exhaust from the boilers is a feature
of energy cabins.
 An ash level monitor prevents too much ash being
fed into the container.
Advantages of this system include:

Excellent ‘Plug & Play’ heat energy solution.

Environmentally friendly energy heating source

Meets the heat energy demand of the nursing home whilst reducing approximately
12 tons of CO2 emissions per annum against fuel oil.

Annual fuel savings of approximately £4000 per annum compared to fuel oil.

Minimum maintenance required, fuel supply monitored by nursing home team
