Why a heat pump

At VIVO, every house is designed all-electric — heating, hot water and, optionally, cooling, from a single heat pump. It is not a lack of gas; it is a choice. Here is why.

A design choice, not a shortcoming

The house is designed to run efficiently without gas. We evaluated heating systems in detail before building and chose the heat pump because it is the right fit for an energy-efficient house — more modern, safer and ready for the years ahead.

Heat pump vs. gas boiler

Below, the direct comparison, criterion by criterion.

Criterion	Heat pump	Gas boiler
Initial investment	Higher, at equipment level	The unit itself, cheaper
What it covers	Heating and hot water; cooling optional	Only heating and hot water
Monthly cost	Low; near zero with solar panels	Comparable today, but the price of gas is rising
Safety in the home	No combustion, no gas-leak risk	Combustion indoors, risk of leaks
On-site emissions	No on-site emissions	Combustion, CO₂ emissions
Maintenance	Minimal	Mandatory annual service
Lifespan	Over 20 years	10–15 years
Energy independence	With solar, almost self-sufficient	Dependent on the supplier and the price
Future-ready	Pairs with solar, a battery, an electric car	A separate system, no integration
The European direction	The standard for new homes	New gas boilers, being phased out

What it means for you

Green mortgage — a class A energy certificate opens access to the green mortgage: you qualify for a preferential interest rate at ING, BCR and Banca Transilvania.
Higher resale value — efficient, class A houses sell faster and at a better price than old, inefficient homes.
A class A energy certificate at handover — verifiable, and the key that unlocks the green mortgage.
Comfort you can feel — steady underfloor warmth, a stable temperature all year, clean air, no cold radiators.

nZEB houses and renewable energy

Since 2021, every new house in Romania is built to the nZEB standard — near-zero energy consumption, with at least 30% of its energy from renewable sources. A conventional gas boiler cannot meet this threshold on its own, because gas is conventional energy. The heat pump is the source that brings the house up to this standard.

The equipment

Natural R290 refrigerant — an environmental impact hundreds of times lower than synthetic refrigerants; it stays the lasting solution as EU rules phase the synthetic ones out. It reaches high flow temperatures, so it works excellently with underfloor heating.
Monobloc system — the entire refrigerant is sealed inside the outdoor unit; only hot water enters the house. Clean installation, minimal risk, long-term reliability.
Smart control & WiFi — a thermostat controlled from your phone: set and schedule the temperature from anywhere, while the system optimises itself automatically for steady comfort and the lowest possible consumption.

The R290 refrigerant is present in a small quantity and, being a monobloc system, fully sealed inside the outdoor unit — it never enters the home.

Frequently asked questions

When will there be gas in the neighbourhood?

The project is all-electric by design — a decision, not a shortcoming. It is the system on which efficient new houses are built.

Does the house have air conditioning?

The pump provides heating and hot water. The same pump can also cool in summer, as an option.

Is the R290 refrigerant safe?

Yes. It is present in a small quantity and, being a monobloc system, fully sealed inside the outdoor unit — it does not enter the house.
