The two latest refurbishment projects, completed in 2008 and 2009 respectively, comprised the installation of a further Andrews Supa-Flo water heater and two Potterton Commercial NXR3 cast iron sectional boilers
. The former has been fitted to provide hot water to the Players' changing rooms and some of the South Stand hospitality suites, while the boilers supply low pressure hot water (LPHW) to the South Stand heating and air conditioning systems.
, for example, allow all of the boiler parts to be brought into a building through a standard sized doorway and then assembled in place.
This makes water tube and sectional boilers
comparatively safe, because each section contains a relatively small amount of water.
According to Saturn Facilities, this large ex-Texas Instruments building needed reliable heating on a continuous 24 x 7 basis and Ferroli's gas-fired GN4 N-14 cast-iron sectional boilers
were chosen for their ability to operate reliably and continuously throughout the year and for their high operating efficiency which helps reduce running costs.
Some cast-iron sectional boilers
are designed with this in mind.
