The System

How many rooms can iSeries serve?

The number of rooms depends on outdoor unit model and application chosen. For example, with an air ducted or an underfloor system it’s possible to heat/cool a lot of rooms with a single installation.

What is iSeries?

iSeries is a full DC inverter heat pump system designed for heating, cooling and domestic hot water service. It fits perfectly both residential (flats, villas…) and commercial (offices, shops…) applications. It’s completely Made in Italy.

I don’t find nominal capacity for every indoor unit. Why?

iSeries gets over old concept of nominal capacity for indoor units. All models are divided in only 4 sizes (A, B, C, D). Capacity of every size can change from a minimum to a maximum value (i.e. size A up to 4 kW) according to operation conditions. The result is higher comfort and reduction of energy input.

How many models of indoor units are there in iSeries range?

There many models available: high-wall, floor/ceiling, console, cassette, ducted. All models can be mixed together (i.e. two high-wall units and two cassette). Check Indoor Units Section for more details.

In my house I have predispositions for air conditioners. Can I install iSeries units?

Yes, of course. All iSeries units can be installed even using predispositions provided for R410A refrigerant gas.

Can I use iSeries for heating when outdoor temperature is very low?

iSeries system is designed to work even where outdoor temperatures are very low (down to -32° C). When operation conditions are so hard, COP (coefficient of performance) is around 1.

What are indoor unit distance limits?

Limits for indoor units installation depend on outdoor unit model and on configuration chosen (monosplit, multisplit…). Check limits table in our catalogue or in Outdoor Units Section.

Where is it possible to install iSeries?

iSeries can be used as air conditioning system almost everywhere: flats, lofts, villas, independent houses but also in offices, shops, restaurants, hotel… Check the Application Section for more details.

Domestic Hot Water (eMix & eMix Tank)

Why eMix is so innovative?

eMix is a step beyond in domestic hot water systems. With eMix unit is now possible to heat water up to 80° C using energy of heat pump. Furthermore, eMix can provide domestic hot water service during cooling operation.

What happens when, during summer, the system is cooling and eMix is heating domestic water at the same time?

This is the best condition for the system. In fact, during this condition eMix is heating the water free of charge recovering energy that would be lost outside.

What is the difference between eMix and eMix tank?

eMix unit has to be connected to any type of buffer thank (even classic electric boilers is ok). eMix tank is provided with a buffer tank integrated.

Is there a limit for storage tank volume connected to eMix?

No, the volume will depend only on requirements. Normally, a family of 4 people requires 200/300 liters of domestic water every day.

Does eMix require electric back up heaters?

It’s recommended to install electric back up heaters inside buffer tank. The heaters will be connected directly to eMix which will use them only when strictly necessary.

There is not a lot of space in my house. Can I install eMix?

Thanks to its small size (less than half of a gas boiler), it’s easy to find a place where eMix can be installed even in a little bathroom. eMix has to be installed in a sheltered room.

Is it possible to connect at the same outdoor unit eMix and standard indoor units?

Yes, it is possible because there is a special refrigerant port for eMix connection. In this way, eMix and standard indoor units (high-wall, cassette, ecc..) can be connected at the same time with a single outdoor unit.

My only purpose is to produce domestic hot water. Can I use eMix?

eMix connected to a single outdoor unit realizes an high-efficiency heat pump system for domestic hot water service.

What is the maximum temperature for water when eMix is used in a monosplit configuration (one outdoor and one eMix)?

In this case, maximum temperature for water is 60°C.

Which type of accessories has to be installed on water circuit?

Accessories required are the same used with any other domestic hot water system (gas or electric boiler): filters or softener, mixing valve, vent valve, etc…

Hydronic Applications (HydroKit)

I want to use underfloor heating system during winter and split indoor units for cooling during summer. Is it possible?

With iSeries technology it’s now possible to connect to the same system hydrokit unit, which will be used for heating during winter, and split indoor units for cooling during summer and heating in the mid seasons.

Where hydrokit unit has to be installed? What is the distance limit?

Hydrokit has to be installed in a sheltered space (technical room). Distance limits are the same as any other standard unit.

In my house there is an underfloor heating system. Can I connect it to iSeries?

Thanks to hydrokit unit, it’s possible to use energy from heat pump to heat the water of an underfloor system. You don’t need any other accessories like gas boilers.
