Heat pump in a new build

In a new build, the heat pump is no longer an option: it is the natural route to the near-zero-energy level (NZEB). On a well-insulated, airtight home, an air-to-water heat pump paired with low-temperature underfloor heating delivers its best efficiency. We size it from the plans, couple it with your photovoltaics and your heat-recovery ventilation — for a new home that heats almost without a bill.

Our new-build approach

A heat pump designed with your home, not bolted on afterwards

In a new build, the fabric is high-performance and everything is decided upstream. We get involved from the design stage to dial in the output, the emitters and the couplings — that is what turns a good heat pump into a truly near-zero-energy home.

Air-to-water heat pump & underfloor heating

On a well-insulated new fabric, the air-to-water heat pump feeds low-temperature underfloor heating (30 to 35 °C). That low temperature means the highest COP and therefore the lowest bill — the ideal pairing in new builds.

Sizing from the plans

We calculate heat losses based on the EPC and the plans, before the structural work. The heat pump is sized precisely: no over-capacity that cycles, no electric back-up that weighs down the bill.

Photovoltaic coupling

In a new build, panels and heat pump are designed together. Part of your heating and hot water runs on your solar production: self-consumption maximised, bill and EPC level both pushed down.

How it works

From the preliminary design to commissioning

  1. Study on plans & EPC

    We start from your plans and your EPC study to calculate the future home’s heat losses, choose the output and position the pipework. Everything is settled before the slabs are poured.

  2. Quote & site coordination

    A clear quote, coordinated with your architect and your trades: underfloor heating, builders’ openings, electrical supply and the routing of ventilation ducts.

  3. Installation integrated into the structural work

    Underfloor heating embedded in the slab, outdoor unit, DHW tank and hydraulic and electrical connections fitted at the right point in the build, with no rework.

  4. Commissioning & EPC tuning

    Balancing of the underfloor circuit, heating curve, coupling with the photovoltaics and the heat-recovery ventilation, then handover of the documents needed for the final EPC and the warranty.

Why the new-build combo wins

Heat pump + underfloor heating + photovoltaics

In a new build, the trio of air-to-water heat pump, low-temperature underfloor heating and photovoltaics forms a coherent system. The underfloor circuit spreads gentle heat at low temperature, which pushes the heat pump’s COP to its maximum; solar feeds part of that consumption. The result: a comfortable home, compliant with the near-zero-energy level, and a heating bill cut to the bone.

  • Low-temperature underfloor heating: optimal COP, even and discreet warmth
  • Photovoltaics that cover part of the heating and hot water
  • A system designed as one to reach the NZEB level without costly back-up

Frequently asked questions

Heat pump in new builds

Is a heat pump mandatory in a new build?

The regulations do not require a heat pump by name, but they do require the near-zero-energy level (NZEB) for any new build in Belgium. In practice, on a well-insulated new fabric, the heat pump is the simplest and most economical solution for reaching that level, especially when coupled with photovoltaics. It has become the default choice for new builds.

Do you need underfloor heating with a heat pump in a new build?

It is not mandatory, but it is the ideal pairing. Underfloor heating works at low temperature (30 to 35 °C), which lets the heat pump run at its best efficiency (high COP) and consume as little as possible. In a new build, the underfloor circuit is embedded in the slab with no rework cost: it is well worth doing from the outset.

At what point in the build should the heat pump be planned?

As early as possible, from the preliminary design. Sizing is done on the plans and the EPC study, and the underfloor heating must be fitted before the slab is poured. The builders’ openings, the electrical supply and the routing of the ventilation ducts are coordinated with the structural work. A heat pump planned late means compromises and avoidable extra costs.

Can the heat pump be coupled with photovoltaics and heat-recovery ventilation?

Yes, and that is the whole point of a new build: the system is designed as one. The photovoltaics feed part of the consumption of the heat pump and the hot water tank. The heat-recovery ventilation recovers heat from the extracted air, which further reduces the heating demand. The three systems complement each other to pull the EPC level towards near-zero energy.

Does the heat pump also handle domestic hot water in a new build?

Yes. We install a domestic hot water tank sized for your household, fed by the heat pump. In a new build, hot water production can also be prioritised during periods of high solar production, to maximise self-consumption. You have reliable hot water all year round with minimal electricity consumption.
