HEAT PUMPS

This series of air-water heat pumps meets the winter and summer comfort requirements in residential installations, as well as small-mid sized commercial ones.

Check quickly how much the heat pump will cost!

The unit is suitable for outdoor installation and can produce hot water up to 60°C. It may be employed in systems with radiant floor, fancoils, radiators and for the indirect production of domestic hot water (DHW) via an external storage tank.

ADVANTAGES:

- Design adapted for external assembly
- One system for heating, active cooling and hot air.
- High energy efficiency ensuring low operating costs
- High flow temperature up to 60 ° C
- Ecological refrigerant R410A
- Excellent devices for new and modernized facilities
- Inverter compressor with power modulation in the range of 30% -120%
- Silent axial fan with vibration compensators
- Electronic expansion valve for high COP
- Advanced automation enabling operation in monovalent mode
   and bivalent (eg with boiler c.o.)
- Easy assembly thanks to the delivery of a completely assembled device
- Access to subassemblies to facilitate service and maintenance
- Small space requirement
- Attractive price - low investment costs

DOMESTIC HOT WATER PRODUCTION

The unit operates in heating mode to reach and keep the temperature inside a DHW cylinder (not supplied) to the setpoint value. A 3-way diverter valve (not supplied) is needed, together with a temperature sensor (T5 probe, L = 10m, provided) to be inserted into one well of the DHW tank.

ACCESSORIES

- Electrical booster (backup heater box) Suitable for indoor installation, it consists in an electric heating element (3kW, 230V-1-50) mounted inside a painted sheet metal box, complete with electrical control panel. The heat pump uses the booster for integration purposes. It is used also as a backup out of the operational limit conditions or for alarm.

ANTIFROST PROTECTION

Guaranteed for outdoor air temperature down to -20°C, thanks to the intervention of all the available sources inside the heat pump: the machine operating in heating mode, together with the onboard electric heating element (as a standard on the plate heat exchanger) and the electric booster (if installed).

HYDRAULIC CIRCUIT

It is inside in a compartment, protected from the air flow, to simplify the maintenance operations. It comprises an electronic circulator (brushless DC motor), water flow switch, automatic air vent, water pressure gauge, expansion vessel, safety valve, water filter. The plate heat exchanger and water piping are thermally insulated to prevent condensation on the external surfaces and reduce temperature loss.

CONTROL SYSTEM

The internal controller manages the inverter system and the correct operation of the compressor. It integrates regulation algorithms based on pre-set climatic curves, which can be selected by the user. It is then possible to handle the DHW circuit, alarm alerts, pump anti-seize cycle and integration with external heating sources. An evolved timer is included for climatic and acoustic comfort program.

ADDITIONAL HEATING SOURCES

(boiler or electric heating element). Depending on the parameters set, these sources can intervene as integration of the heat pump, when there is requirement for space heating or for DHW production. The external sources can be automatically switched on, also as a backup, in case the heat pump cannot work for anomaly error or operational temperature limits.

HEATING AND COOLING SYSTEM

The unit, when active in heat or cool mode, modulates the frequency of the compressor with the aim to keep system temperature to the setpoint value.

WEEKLY TIMER

Scheduling on 6 time bands per each day of the week, with specification of the operating mode (COOL / HEAT / DHW) and the required setpoint.

ECO/COMFORT

It is possible to define daily time bands and corresponding set point for ECO and COMFORT modes, either in heating or cooling operation

FAST DHW

This manual function permits to reach DHW setpoint in the shortest time, using all available heating sources.

SILENT MODE

Provided the function is enabled, it is possible to schedule up to 2 periods (normally night/rest ones) when the appliance shall operate in low-noise mode. The maximum frequency of the compressor will be thus reduced, together with fan’s speed. Acoustic drop rate can be set in 2 levels.

REMOTE ON / OFF

using an external contact. The unit can be switched on and off via an external contact.

TESTIMONIALS

We also install underfloor heating in Irish homes

Underfloor heating and cooling is a form of central heating and cooling which achieves indoor climate control for thermal comfort using conduction, radiation and convection. The terms radiant heating and radiant cooling are commonly used to describe this approach because radiation is responsible for a significant portion of the resulting thermal comfort but this usage is technically correct only when radiation composes more than 50% of the heat exchange between the floor and the rest of the space.
