European Residential Range

R290 Residential Air-to-Water Heat Pumps

EXINDA's R290 range is six monoblock heat pumps, 6 to 30 kW, for European homes and small buildings. Up to 12 kW they run on single-phase power, so a boiler replacement needs no rewiring; from 15 kW they are three-phase and cascade up to eight units. Two 20 kW units supply the hot water for a 20-apartment building near Milan.

Selection guidance

How to select an R290 monoblock

Where the range fits

Single-family retrofits and new builds on 12 kW and below; larger homes, villas and multi-residential DHW on 15 to 30 kW, with cascade of up to 8 units for bigger loads. Underfloor heating, fan coils, radiators, buffer and DHW cylinders.

Where it does not

Sites that need more than 60 °C leaving water for the heating circuit. Single-phase sites with a design heat loss above what the 12 kW table gives at the winter design temperature. Loads above the published capacity at design temperature without cascade or backup.

Select at the design temperature

Nameplate capacity is the A7/W35 point. Every product page publishes the maximum-modulation heating row at A2, A−7 and A−15; size from the row that matches the project, not from the nameplate.

Questions & answers

R290 range questions

Who holds the certification for these models?

EXINDA. Each of the 6, 9, 12, 15 and 20 kW models has its own Heat Pump KEYMARK registration (041-K114-01 to -05, issued by BRE Global), MCS HP0403 reference and BAFA BEG Anlagennummer; the certificate and the public register are linked on every product page.

Are the units SG Ready?

Yes. All five models carry the SG Ready interface, which is a condition of the BAFA BEG listing in Germany.

Which models are single-phase and which are three-phase?

6, 9 and 12 kW run on 220–240 V single-phase. 15, 20 and 30 kW run on 380–415 V three-phase. Cascade control of up to 8 units is stated in the submittals for the range.

What does a distributor send to start?

Target country, typical project type (single-family retrofit, multi-family DHW or light-commercial), the capacities that fit your customer base, and expected annual volume. EXINDA returns the certificates and submittals for the applicable models, pricing and sample-unit terms.
