FITTED EQUIPMENT- The Alde Heating System

Central Heating

The boiler is set to an upper limit temperature
of 85°C, i.e., the temperature of the heat
transfer fluid (HTF) as it circulates around the
pipes, radiators, convectors, etc.
To ensure the best performance from hydronic
heating, air must be able to circulate freely
around the back of the furniture (Fig.3). Air
vents, cut into the top and bottom of the
furniture, must be unobstructed by carpets,
cushions, or stowage, etc.
The full length of a convector should be
ventilated for best performance.
Use gas and electric heating
i
simultaneously for the best
performance. The boiler will only use
as much energy as is needed, and is 93%
efficient on a SEDBUK (seasonal efficiency of
domestic boilers in the UK) based test.

Circulation Pump

A pump is used to circulate the HTF around the
central heating system. There are three models
of Alde circulation pump.
• 12v expansion tank circulation pump. This
light duty pump is ideally suited for holiday-
makers, or as an off-grid option for the 230v
inline circulation pump.
• 12v inline circulation pump. This heavy duty,
variable speed pump is designed for all year
round motorcamping.
• 230v inline circulation pump. This heavy duty
pump is powered directly by mains electric,
suitable for non-touring vehicles.
