Characteristics of REMKO inverter heat pumps
Outdoor air as a heat source
An air/water heat pump absorbs energy from the
outdoor air as its heat source and transmits this to
the heating system. They have the following
advantages over brine/water and water/water heat
pump systems:
n
Can be used everywhere Air is available every-
where in unlimited quantities. For example, no
wells are required.
n
No excavation required. No large areas are
required for soil collectors.
n
Economical. Expensive drilling is not required.
n
Excellent value for money and simple installa-
tion.
n
Particularly suitable for low-energy houses with
low inlet temperatures.
n
Ideal for bivalent operation, in order to save
energy.
