Heat Pumps in Varna — Air-to-Water and Monoblock
A heat pump is the most efficient way to heat a home or villa in Bulgaria today — up to 70% lower running cost vs a gas or electric boiler. Daikin, Mitsubishi, Gree and Hitachi with delivery, installation and service by our team in Varna.
Why a heat pump
A heat pump extracts heat from outdoor air and transfers it into your home. Just 1 kW of electricity becomes 3-5 kW of heat — that's the COP coefficient. Result: lowest heating cost vs any alternative.
Up to 70% lower running cost
Vs gas or electric boiler. On a 150 m² house the difference is €1500-2500 per year at current Bulgarian electricity prices.
Heating + cooling + DHW
One device covers three needs — winter heating, summer cooling and domestic hot water. Replaces gas boiler, water heater and AC.
Operates down to –25°C
Modern inverter heat pumps (Daikin Altherma 3, Mitsubishi Ecodan Zubadan) operate reliably to –25°C — more than enough for any part of Bulgaria.
EU subsidies 35-50%
Through the REPowerEU programme and national energy efficiency schemes you can receive 35-50% non-refundable aid for a heat pump.
Monoblock vs split heat pump — what's the difference?
Two main types of air-to-water heat pumps. The choice depends on location, budget and installation conditions.
Monoblock (all-in-one)
The entire refrigeration circuit is in the outdoor unit — on the roof or beside the house. Inside there's only a hydraulic module with antifreeze pipes. Easier installation, no F-gas licence required. Slightly higher price. Suitable for most cases.
Split (outdoor + indoor)
Outdoor compressor + indoor hydraulic module, connected by copper pipes and refrigerant. The piping between them is more complex, requires a licensed technician. More affordable price. Suitable when outdoor space is limited.
Available heat pump models
We've selected popular models for a home or villa in Varna. Prices include VAT, excluding installation. Installation is quoted individually based on capacity and site conditions.






Heat pump installation
Air-to-water heat pump installation is significantly more complex than an AC — it requires a hydraulic schematic, expansion tank, circulation pump, buffer tank. We work only with licensed technicians.
- Standard monoblock up to 12 kW — from €1500
- Monoblock 14-16 kW — from €1800
- Hydraulic schematic, all materials included
- 12 months workmanship warranty
Service and maintenance
Annual heat pump maintenance — evaporator cleaning, refrigeration circuit check, electronics test, circulation pump check. Preserves efficiency and warranty.

What is an air-to-water heat pump and how does it work?
An air-to-water heat pump extracts heat from outdoor air and transfers it into the water of your heating system (radiators, underfloor heating, water heater). It works on the same principle as a refrigerator but in reverse — from 1 kW of electricity it produces 3-5 kW of heat.
How much do I save vs gas or electric boiler?
Vs electric boiler — 60-70% (the heat pump produces 4 kW of heat from 1 kW of electricity). Vs gas boiler — 30-50% depending on gas price. On a 150 m² house the difference is €1500-2500 per year at current prices.
How much does a heat pump cost in Varna?
Monoblock 8 kW (for an apartment or small house up to 100 m²) — from €4500. Monoblock 12 kW (house 150-180 m²) — from €6500. Monoblock 16 kW (large house 200-250 m²) — from €8500. Prices include VAT, excluding installation (€1500-2500 extra).
What is COP/SCOP and why does it matter?
COP is the heat:electricity ratio at the moment of operation. SCOP is the seasonal average. A quality heat pump has SCOP 4.0-4.5 — it produces 4-4.5 kW of heat per 1 kW of electricity. Premium models (Daikin Altherma 3 R) — up to SCOP 5.0.
Are there EU subsidies for heat pumps in Bulgaria?
Yes — through the REPowerEU programme and national energy efficiency schemes you can receive 35-50% non-refundable aid. The amount depends on region, dwelling type and energy class. The procedure requires project documentation and certified installation — we help with both.
How long does delivery and installation take?
For models in stock (Daikin, Mitsubishi, Gree) — 7-14 days delivery. Installation takes 2-4 days depending on the site (new install vs replacement). For subsidised projects the timeline is longer due to paperwork — 1-2 months total.
