Heating capacity and COP at A7/W35: outdoor air 7 °C, water outlet 35 °C. Both fall as the outdoor temperature drops or the water temperature rises. Cooling figures are the manufacturer's nominal ratings. Nominal water flow corresponds to the rated heating output at a 5 K flow/return difference. Compare all four models.

Ground source

Ground source heat pump

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. Comparing options? See air source or ground source.

RG series · water and brine to water

8 – 30 kW · indoor installation · five operating modes

  • Ground water near 10 °C gives a COP above 4.4 with no seasonal drop and no defrosting
  • Heat recovery mode produces hot water and chilled water at the same time, reaching COP 7.83–7.87
  • Plate heat exchangers on both circuits with an Emerson electronic expansion valve
  • 29–36 dB(A) — quiet enough for a plant room next to living space

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. Send us the site data for a model proposal.

Indoor terminals

The units that deliver it into the room

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.

  • Low-noise DC motor with a foam-lined air path; bottom air inlet with integrated filter cuts 3–9 dB

The company

Spanish heat pump engineering, built in China

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 Hong Kong, manufactures in mainland China and also operates in New Zealand.

HK

Hong Kong headquarters

Renova Heat Pump is headquartered in Hong Kong, the base for its international sales, export and distributor enquiries.

ES

Spanish engineering

The thermodynamic design, hydraulic layout and control strategy come from Spain, where air-to-water heat pumps have been mainstream equipment for decades.

CN

Chinese manufacturing

Production sits in mainland China, which is where the supply chain for compressors, exchangers and inverter boards actually lives — and what keeps the price competitive.

NZ

New Zealand operations

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.

Solutions

Built around the emitters you already have

Underfloor heatingLow flow temperatures suit a heat pump best and give the highest seasonal efficiency.
Radiator heatingExisting radiators can often be kept; oversized panels or a higher flow temperature compensate.
Fan coil systemsOne circuit heats in winter and cools in summer with the same fan coil terminals.
Domestic hot waterA cylinder with priority control produces hot water without interrupting heating for long.
New build and retrofitSizing, emitter choice and controls differ; both cases are handled at design stage.
Light commercialOffices, guesthouses and small hospitality loads, with cascade operation where needed.
How it works

Heat that is moved, not burned

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.

The source gives up heat

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.

The compressor raises the temperature

Compressing the refrigerant concentrates that heat into a smaller volume at a much higher temperature.

Heat passes into your water

In the condenser the refrigerant releases its heat into the heating circuit, then expands and starts the cycle again.

The building uses it

Water is distributed to fan coils, underfloor loops or radiators, and to the hot water cylinder when required.

  1. Air or ground
  2. Evaporator
  3. Compressor
  4. Condenser
  5. Heating water

The same circuit reverses in summer to deliver chilled water for cooling.

Technology

What the components actually do

Inverter-driven compressor

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 refrigerant

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.

Monobloc hydraulic layout

On air-to-water units the refrigerant circuit stays outdoors; the installer connects flow, return and power, with no refrigerant work inside the building.

Controller and app

A 7-inch multilingual touchscreen sets heating, cooling, hot water and schedules; Wi-Fi adds remote monitoring and control. More on the technology.

Photovoltaic readiness

The SG Ready interface lets an energy manager signal surplus PV generation, so the heat pump can store it as heat in the buffer or cylinder.

Questions

Frequently asked questions

How do the RV models perform in cold weather?

The RV DC inverter series is designed for heating in outdoor temperatures down to −20 °C, subject to operating conditions and system design. Capacity and COP are not constant: both fall as the outdoor temperature drops and as the required water temperature rises, so the unit is sized at the local design temperature, not at the A7/W35 rating.

Air source or ground source?

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.

Will it work with my existing radiators?

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. See emitter options.

Can one unit heat and cool?

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.

How much electricity will it use?

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.

Who is behind Renova?

Renova is a Spanish–Chinese partnership headquartered in Hong Kong. The heat pump engineering — cycle design, hydraulics and control logic — comes from a Spanish team; manufacturing is in mainland 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. More in the company.

Do you supply distributors and OEM partners?

Yes. Tell us your market, expected volume and certification requirements and we will send the commercial and documentation package.
