Range & application

Thermodynamic solar systems

Solar Block all-in-one units in 150, 200 and 300 litres, energy class A+++, COP up to 4.2 at 14°C, operating from −5°C to +55°C ambient, in enamelled steel with Inox 444 or duplex 2205 tank options, R290 or R134a closed loop, 1.5kW backup immersion, optional WiFi monitoring, and warranties of five years on the tank, two on the compressor and ten on the panel, with savings up to 80%. Solar Block Split separates panel from tank, in one-to-six panel arrays against tanks from 100 to 1,000+ litres, with panels at 2,000 × 800 × 20mm in aluminium with a selective absorber coating, salt-air rated for coastal and marine exposure, roof, wall, ground or shade mounted, pre-charged copper lines to 15m, and single-coil, double-coil or buffer-plus-DHW tank variants. Solar Block Plus scales the same technology industrially from SB 6 at 7.5kW through SB 12, SB 16 and SB 28 to SB 40 at 54.6kW, with buffer tanks from 500 litres to 6,000 litres, 230V and 400V supplies, output to 55°C around the clock and units linkable for greater capacity. Solar Block Ultra covers very high household draw and small commercial, and Eco and Eco XL stand-alone panels retrofit to existing tanks from 1,000 to 6,000 litres.

Heat pump water heaters

EcoTop residential units at 100, 200 and 300 litres with COP from 3.4 to 4.5 depending on model and air temperature, heating power 0.95–2.5kW with 1.5–2.0kW backup, R290 natural refrigerant, vitreous enamel tanks, 50mm PU insulation, 52–53 dB(A), IPX4, energy class A+, LCD touch display, automatic weekly anti-legionella cycle and optional WiFi. Aquapura Monobloc Pro at 200 and 270 litres nominal (195 and 265 usable) on R290 with GWP around 3, COP from 3.22 at 7°C to 3.94 at 20°C, published annual consumption figures at each air temperature, DHW to 65°C, 53 dB(A) sound power and 36 dB(A) at two metres, a 60 × 60cm footprint, WiFi and Modbus as standard, floor-standing or wall-mounted, with ECO, Boost and Holiday modes and a replaceable magnesium anode. Aquapura Split Green separates compressor and tank for retrofits where indoor space is tight.

Solar thermal systems

Solar Box pressurised forced-circulation systems in 200, 300 and 500 litre tanks with two to six flat-plate collectors using TiNOX selective absorbers, optical efficiency to 0.79, heat-loss coefficient 3.7 W/m²·K, 4mm tempered low-iron anti-glare glass, salt-spray-tested anodised aluminium frames, 6 bar collector and 10 bar tank working pressure, 198°C stagnation, propylene glycol frost protection, integrated pump station and controller, and electric immersion backup with optional gas or heat-pump tie-in. Solar Box thermosiphon systems in 200 and 300 litres run on gravity with no pump and no running electricity, with one or two integrated collectors, horizontal twin-port tanks, stainless-steel base, magnesium anode and 2kW element — the simplest retrofit and the right answer for off-grid villas.

Pool heat pumps

Energie Aquapura Inverter units from 9kW to 30kW covering uncovered pools from 15m³ to 150m³ and covered pools to 180m³, with COP up to 15.0 at 26°C air and 26°C water, R32 refrigerant, operation from −7°C to +43°C, titanium heat exchangers for chlorinated and salt-treated water, DC inverter compressors, 48–55 dB(A), WiFi app on every model, and five-year titanium and two-year unit warranties.

Heating and climatisation

Aquapura Inverter units from 4kW to 20kW delivering heating, cooling and domestic hot water from one machine, with nominal heating COP around 4.8, SCOP to 5.36 at 35°C, R32, operation from −25°C to +43°C, water output to 60°C, 37–58 dB(A), A+++/A++ energy class, DC inverter compressors, wall or pedestal mounting, WiFi, five-year warranty and compliance with EN 14511-2, EN 14825 and EU Ecodesign 2021/92. The Aquapura Inverter HT variant on R290 reaches 75°C outlet as a monobloc with no split refrigerant lines, suiting radiator retrofits in existing villas with fast commissioning. Applications: underfloor heating and cooling, fan-coil systems, combined heating and DHW, and radiator retrofit.

Commercial and industrial systems

Aquapura Inverter X-Series high-temperature units at 30, 60 and 75kW, cascadable master-and-slave to beyond 500kW, delivering DHW to 75°C from −25°C to +43°C, COP 4.6 at 35°C and 3.5 at 55°C, R32 with twin-rotary DC inverter compressors, buffer tanks from 1,000 litres up to 50,000 in cascade, monobloc or split configuration, Modbus RTU/TCP and KNX for BMS integration, automatic thermal disinfection, and A++/A+++ energy class. Typical applications: hotels of 50–400 rooms, labour camps of 200–2,000 occupants, hospitals and clinics, industrial and food-and-beverage plants, and sports facilities. The Aquapura Booster water-to-water heat pump lifts existing 45–55°C output to full legionella-cycle temperature at up to 75°C, drawing from boreholes, geothermal loops, seawater intake, district heating return or an existing heat pump, achieving COP above 6 where source water sits between 25 and 35°C — suited to hospitals, hotels, large compounds, district hot-water schemes, industrial process water and seafront projects.

Cylinders, tanks and accessories

Thermobox storage cylinders with high-grade PU insulation, dual coil options and integrated sensor wells, compatible across the EcoTop, Monobloc Pro, Inverter and X-Series ranges. Thermobox Duo combines heating buffer and DHW cylinder in one stratified unit with a stainless coil for hygienic separation, saving plant-room footprint and capital cost, with a Duo Light variant for smaller villas and apartments. Termo XL buffer tanks to 6,000 litres with low standby losses, multiple sensor pockets and BMS-ready terminals for cascade and commercial plant rooms. Hydrokit pre-assembled hydraulic modules bring circulator, expansion vessel, safety valves, sensors and three-way valve into a wall-mounted unit installed in about an hour rather than days of plumbing — a genuine differentiator on installation cost that deserves more prominence than an accessories listing.
