Design fan coil: climate control for the whole home in 12 centimetres.

The radiator is the heat pump's enemy, even for heat pumps using the eco-friendly R290 gas: to heat properly it needs water at 65–70 °C, and at those temperatures the SCOP collapses. The result is that the electricity for heating may cost more than the gas burned by the old boiler. Reverso is a new generation of fan coil that works at low temperature and brings the heat pump, with R32 or R290 gas, to its best SCOP. It also heats the room in a few minutes and cools and dehumidifies in summer.

Yes, for heating. The whole Reverso range connects to the existing radiator pipes, even 12 mm diameter ones: in this case it is used for heating only, with a temperature difference (ΔT) of 20 °C. No chasing walls and no new floors. For cooling as well you need larger insulated pipes, at least 16 mm, and a condensate drain; where there is no slope, an optional condensate pump is available.

Reverso starts at €524 list price, control and valves excluded. The cost of the system depends on how many rooms you want to air-condition: usually one Reverso per room. Thanks to its efficiency, comfort is higher and the heat pump or boiler works at maximum efficiency: with the savings on your bills, the cost difference between a radiator and Reverso is recovered in one season. Room-by-room sizing and the full quotation are free.

It depends on the home's insulation and the water temperature. For example, in a renovated home with average insulation a Reverso FS 400 with water at 50 °C heats about 25 m². We calculate the right size for each room with our simulation software, for free.

Very little: the Reverso DC Inverter motor draws from 3 to 17 W depending on size and speed, less than a light bulb. Heating and cooling are produced by the heat pump or boiler; Reverso, working with low-temperature water, lets them run at their most efficient point.

A split system has outdoor units connected to the indoor units through refrigerant gas which, in case of leaks, is toxic and also flammable. A fan coil uses the water produced by the heat pump or boiler. Unlike splits, with Reverso you can manage the water temperature: in cooling you reduce the cold draughts typical of splits, and the same applies to heating. It can also be combined with underfloor systems, which is not possible with splits. The result is greater comfort and a much more eco-friendly system.

Traditional ones are bulky, noisy and move a lot of air. Reverso is 12 cm deep, has a tangential fan delivering an even, quiet airflow, around 20 dB(A) at minimum speed, and an optional radiant panel for gentler heat. Two things to know: cooling needs a condensate drain, and the filter should be washed 2-3 times a year.

With water from the system, hot in winter and cold in summer, and a standard 230 V power supply for the fan and control.

It's the ideal match. Reverso performs with low-temperature water, 40–45 °C in winter, and in summer at 7–12 °C or even 10–15 °C, so the heat pump runs with higher SCOP and SEER.

At minimum speed the sound pressure is about 20 dB(A) at 1 metre (ISO 7779), below the threshold of hearing. The aluminium tangential fan avoids the typical noise of centrifugal fans.

Yes, with Reverso BT: it is the only bathroom fan coil, thanks to IPX4 protection, with chrome aluminium towel rail and radiant panel as standard. This matters because it works at low temperature. With a heat pump the water is at low temperature and bathroom towel radiators perform poorly: the bathroom stays cold and electric heating elements often have to be added. Reverso BT heats well even with water at 40–45 °C.

With a 4-pipe system, yes: FS and SM are available with a 3-way valve for 4 pipes, heating and cooling simultaneously. The cost of the Reverso unit doesn't change, but the system costs more.

No: the stainless steel micro-wave filter is washable and lasts forever. Optional antibacterial and antiviral filters are available for those who want more.
