Freon R404a Air Source Heat Pump Underfloor Heating / Home Heat
Pump Systems
Air Source Heat Pump Underfloor Heating advantages
1. Economical Operation: generally cost less to operate than other
types of conventional heating systems, save your electricity or gas
bills
2. Easy Operation: With intelligent control systems which
convenient and simple operation
3. Safety: Operate at a high efficiency with no flames,fumes,or
flues;Water and electricity isolated
4. Constant hot water supply: provide hot water no matter in cloudy
day,snow day or at night,unlike solar collectors which have to be
facing the sun
5. Environmental friendly: Transfer heat that's already in the
environment;low CO2 emissions
Air Source Heat Pump Underfloor Heating application
Air Source Heat Pump Underfloor Heating can be applied to sanitary hot water,house heating,swimming pool
and spa pool temperature and so on
