Renova supplies the whole hydronic chain: an R32 EVI inverter heat pump or a ground source unit as the heat source, and slim hydronic fan coils as the terminals. Everything inside the building carries water, so no refrigerant work is needed indoors.
The flagship outdoor unit. Full DC inverter control with enhanced vapour injection, so rated capacity holds as the outdoor temperature falls and the electric backup heater stays off.
12 – 19 kW · single phase · heating, cooling and hot water
Performance measured by the manufacturer at the stated water and ambient conditions; cooling at A35 with 18 °C water outlet. Multi-function versions covering heating, cooling and domestic hot water in one unit are available on request.
Where a borehole, ground loop or well is available, the source temperature stays stable all winter. The unit sits indoors in a plant room: no outdoor unit, and no defrost cycle at all.
8 – 30 kW · indoor installation · five operating modes
Heating at W10/W35 uses ground water at 10 °C; B0/W35 uses brine at 0 °C, the harder of the two cases. Cooling is measured with 12/7 °C on the load side. Figures are the manufacturer's; the ground loop or well itself must be sized by the drilling contractor.
A heat pump only produces warm or chilled water. What the occupant actually feels is the terminal. Renova supplies hydronic fan coils on the same water circuit — one set of units for winter and summer, with no refrigerant piping indoors.

Fan coil figures are manufacturer test data for the supplied series. Slim units are rated with 7 °C water in cooling and 45 °C water in heating.
Renova is the result of one working relationship: a Spanish engineering team that has spent its career on hydronic heat pump design, and a Chinese manufacturing team that turns that design into series production. The company is headquartered in China and also operates in New Zealand.
The thermodynamic design, hydraulic layout and control strategy come from Spain, where air-to-water heat pumps have been mainstream equipment for decades.
Headquarters and production sit in China, which is where the supply chain for compressors, exchangers and inverter boards actually lives — and what keeps the price competitive.
An operating presence in New Zealand covers the southern hemisphere heating season and gives the engineering team field feedback from a very different climate.
Two engineering cultures, one product: European design discipline with Chinese industrial scale.
A boiler converts fuel into heat. A heat pump moves heat that already exists — in outdoor air or in the ground — into your heating water. That is why its output is a multiple of the electricity it consumes.
A fan draws outdoor air across the evaporator, or ground water and brine pass through a plate exchanger. Refrigerant absorbs low-grade heat from either source.
Compressing the refrigerant concentrates that heat into a smaller volume at a much higher temperature. EVI models inject vapour mid-compression to hold capacity in cold weather.
In the condenser the refrigerant releases its heat into the heating circuit, then expands and starts the cycle again.
Water is distributed to fan coils, underfloor loops or radiators, and to the hot water cylinder when required.
The same circuit reverses in summer to deliver chilled water for cooling.
Variable-speed control adjusts output to the building's real demand instead of switching on and off at full power, which reduces cycling losses and improves part-load behaviour.
R32 has a global warming potential of 675 against 2088 for R410A, and its higher volumetric capacity means a smaller charge transfers the same amount of heat.
On air-to-water units the refrigerant circuit stays outdoors; the installer connects flow, return and power, with no refrigerant work inside the building.
Weather compensation adjusts flow temperature to outdoor conditions; hot water priority, scheduling and fault history are available on the controller and in the app.
Below freezing an air-source coil ices up. Demand-based defrost reads coil conditions instead of running on a fixed timer — and a ground source unit never defrosts at all.
A volt-free contact lets a PV inverter raise the setpoint when surplus generation is available, storing that energy as heat in the buffer or cylinder.
Enhanced vapour injection feeds a second, intermediate stream of refrigerant into the compressor. It keeps the compression ratio inside the safe envelope when outdoor air is very cold, which is why an EVI unit still delivers useful capacity at −25 °C where a standard circuit would have to stop or fall back on an electric heater.
Air source is cheaper to install and needs no drilling. Ground source costs more up front because of the borehole or well, but the source stays near 10 °C all winter, there is no defrost cycle, the unit lives indoors and seasonal efficiency is higher. Above roughly 15 kW and in cold climates the ground source case gets stronger.
Often yes, but flow temperature decides efficiency. Radiators sized for a boiler at 70 °C may need to run hotter than ideal, so we check emitter output at a lower design temperature and advise where a panel should be upsized.
Yes, if the emitters allow it. Fan coils deliver both. Underfloor circuits can provide gentle cooling with dew-point control, while radiators cannot cool at all. Ground source units add a heat recovery mode that produces hot water and chilled water simultaneously.
That depends on your building's heat loss, the flow temperature your emitters need and your climate. An honest figure needs the heat-loss calculation and the model's performance table — send us the building details and we will work it out rather than guess.
Renova is a Spanish–Chinese partnership. The heat pump engineering — cycle design, hydraulics and control logic — comes from a Spanish team; manufacturing and the company headquarters are in China, where the component supply chain is; and the company also operates in New Zealand, which puts a second heating season in front of the same engineers each year.
