Chofu heat pumps · made in Japan
What is inside
Monobloc: the refrigerant stays sealed inside the outdoor unit, and only water enters the house.

Official Chofu importer
The only authorised distributor for Eastern Europe, since 2018.
Over 5,000 pumps
Sold across Romania through NEDAVI and its partners: houses, guesthouses and industrial halls.
3- and 5-year warranty
Three years on the unit, five on the compressor, with service in Romania.
Natural refrigerant R290
GWP 0.02 under Regulation (EU) 2024/573, outside the EU restrictions on fluorinated gases.
The R290 range
The R290 models use propane, a natural refrigerant: GWP 0.02, against 2,088 for R410A. They reach a 75 °C flow temperature, so they also work with existing radiators.

What's included besides the heat pump
The “from” amount only covers items that already have a price; we set the rest in the quote. This is an estimate, not a final price: installation depends on the house, the distance to the plant room and the heating system you have now. Final price after survey and quote.

How it works
In short
The pump does not produce heat, it moves it. It takes the heat that is already in the outdoor air, even at minus twenty degrees, and pushes it into the water in your heating system. The electricity is not turned into heat: it drives the compressor that does the moving. That is why one kilowatt you pay for brings more than one kilowatt of heat into the house, something a boiler, which burns fuel to make heat, can never do.
On the datasheet
The ratio is called COP: the heat delivered divided by the electrical energy consumed, measured under declared conditions. A7/W35 means 7 °C outdoor air and a 35 °C flow temperature. SCOP is the seasonal average. Both rise as the flow temperature falls, which is why underfloor heating beats radiators, and why correct sizing matters more than the model you choose.
10 kW Premium R290 model, at 7 °C outdoors and a 35 °C flow temperature. At minus 7 °C outdoors, the same unit delivers 10.0 kW.
Why a heat pump
A gas boiler turns one kilowatt of gas into one kilowatt of heat at most. A heat pump does not produce heat, it moves it from the outdoor air into the house. For every kilowatt of electricity it uses, it delivers between three and five kilowatts of heat.
How we work
You tell us the floor area, the insulation and your current system. We tell you how many kW you need.
You get an itemised quote with the pump, the cylinder, installation and delivery as separate lines.
You accept the quote and pay online by card, or by bank transfer against a pro forma invoice.
We deliver. A certified Chofu partner installer from your county, whichever you choose, fits and commissions the pump.
Government funding
No programme for heat pumps is open on afm.ro: Casa Eficientă Energetic has been suspended since 15 December 2021, and Casa Verde Fotovoltaice funds solar panels, not heat pumps. If a funding round opens, we prepare the technical part of the application for you, free of charge.
Programme status checked on 17 September 2026. The amounts and the timetable are set for each round, in the guide AFM publishes.
