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 Usable in all situations Air is available every-
where in unlimited quantities. For example, no
wells are required.
n No excavation needed. No large areas are
required for soil collectors.
n Cost-effective. Expensive drilling is not
required.
n Good price/performance ratio and easy instal-
lation.
n Particularly well suited to low energy houses
with low inlet temperatures.
