Geothermal heating that pays off long‑term — the right plan from first calculation to stable operation

Geothermal heating is one of the most efficient and stable heating solutions if you want to reduce energy costs and enjoy even warmth year‑round. But it’s also a system where “right from the start” makes a huge difference. A good geothermal installation isn’t just about which heat pump you choose — it’s about the whole picture: sizing, borehole, energy demand, distribution system (radiators/underfloor heating), balancing and how the installation is actually done.

We help homeowners and businesses in the Falkenberg municipality with geothermal heating — from advice and sizing to installation and service‑friendly pipework. In many projects that also means coordinating drilling and ensuring everything around it is done correctly: indoor unit placement, piping, safety solutions, condensate/drain, and a clear startup where the system is set for your home and habits.

A common mistake is to compare offers only by “pump kW”. In practice you want a solution that handles peak loads without running inefficiently, provides good hot‑water capacity, and is set so the home is warm without constant adjustments or unnecessary wear. That’s why we focus on understanding the conditions: home size and standard, historical energy use, heat distribution, and any future plans (extension, more underfloor heating, pool, etc.).

When geothermal heating is correctly sized and properly balanced, you get a system that just runs — quiet, reliable and energy‑efficient. And just as important: it should be easy to service and understand. We explain what matters in practice, what to expect in operation, and how to get the most from your investment over time.

Common questions about geothermal heating

What does geothermal heating cost in the Falkenberg municipality?

The cost depends mainly on energy demand, drilling depth, ground conditions and how the existing heating system is set up (radiators, underfloor heating, older pipework). That’s why two “similar” houses can end up with different total costs — drilling and adaptations can vary a lot.

Beyond the pump itself, the price often includes pipework, electrical work, penetrations, potential hot‑water solutions and startup/balancing. In some cases adjustments to the heating system are needed, such as improved radiators or flow tuning.

The key is comparing offers on the same basis: how the system is sized, what assumptions are used, and what is actually included.

We’re happy to put together a solution that fits your home and clearly explain what drives the cost.

How do I know if my house is suitable for geothermal heating?

Most homes with a water‑based system (radiators or underfloor heating) are good candidates. If you currently have an electric boiler, oil, pellet boiler or another water‑based system, geothermal is often a natural next step.

What matters most is energy demand and how efficiently heat can be delivered via radiators/underfloor heating. Homes with older, small radiators may need adjustments to run lower supply temperatures and maximize efficiency.

Plot conditions also matter: access for a drilling rig, distances, and practical considerations for borehole placement and pipe runs into the house.

If you’re unsure, we assess your system, usage and goals so you get a clear answer before investing.

How deep does drilling need to be for geothermal heating?

Drilling depth is driven by how much energy needs to be extracted over time. It depends on the home’s energy demand, system sizing, hot‑water needs and sometimes geological conditions.

Too shallow a borehole can reduce efficiency and risk lower brine temperatures, which can decrease performance and increase wear. Too deep can be unnecessarily expensive.

The right depth is about balance: enough for stable operation and good output, but not oversized without reason.

We use data (consumption/energy demand) to build a sizing that holds over time — not just “works on paper.”

Do I need permits to drill for geothermal heating?

Often a municipal notification/permit is required for energy drilling, but the exact process can vary by area and local rules. It’s about ensuring proper distances to neighbors and other wells, and safe drilling practices.

This needs to be handled correctly because poor placement or lack of documentation can create issues later — both practically and during property sale.

In practice, it usually goes smoothly when handled properly from the start with the right documentation.

We can guide you on what’s normally required and how to plan drilling without unnecessary surprises.

Can I have geothermal heating if I already have underfloor heating or radiators?

Yes — and it’s often a big advantage. Underfloor heating typically needs lower supply temperatures than radiators, which lets a geothermal heat pump run especially efficiently.

Radiators also work very well, but efficiency depends on how “warm” the system needs to be. Large radiators and good flows allow lower temperatures and higher efficiency.

In some homes, replacing a few radiators or adjusting the system can greatly improve compatibility with a heat pump.

We look at the full system and suggest changes that deliver real results — not just theoretical improvements.

How much can I save with geothermal heating?

Savings depend on what you have today (direct electric, oil, older heat pump, pellets), how much energy the house uses, and how the geothermal system is sized and tuned. Geothermal performs best when energy demand is relatively high and stable over many years.

It’s important to calculate with the right factors: not just estimated kWh savings, but also comfort, hot‑water capacity, future electricity prices and how long you plan to stay in the home.

A properly balanced system can make a big difference compared to one that is just “installed and left.”

We help you get a realistic picture of expected savings and what influences them most in your case.

What’s the difference between geothermal and air‑to‑water heat pumps?

Geothermal draws energy from the ground and therefore has very stable conditions year‑round. That often means more consistent output and good efficiency even in cold weather.

Air‑to‑water draws energy from outdoor air and can be cheaper to install because there’s no drilling. But efficiency is more affected by outdoor temperature, especially during colder periods.

The choice often comes down to investment level, plot conditions, energy needs and how long‑term your plans are. Geothermal is often strong for those who want maximum stability and long service life.

We can compare the options based on your home and goals so you choose what actually fits best.

How long does a geothermal installation take?

Time depends on scope, drilling planning and access in the technical room. Drilling itself is often a separate step, and the in‑house installation is scheduled around it.

Beyond mounting, there is pipework, connection to the existing system, adjustments and startup. The final part — settings and walkthrough — is just as important as the installation itself.

A good plan minimizes downtime and gets you stable operation quickly, without “teething problems.”

We plan the work clearly and communicate what happens at each step so you know what to expect.

Do I need to service a geothermal heat pump?

Geothermal heat pumps are generally reliable, but regular checks and service can extend lifespan and keep efficiency high. That can include checking pressures, flows, filters, settings and that the system runs as intended.

Many issues start as small deviations: slightly worse hot water, uneven heat or the pump working harder than necessary. Catching them early is often quick and easy to fix.

Service is also a good time to optimize settings based on how the house is used — especially if something has changed (renovation, extension, new habits).

We’re happy to help with troubleshooting and ongoing maintenance.

What mistakes should I avoid when getting geothermal heating?

The most common mistake is underestimating the importance of sizing and borehole depth. A system that’s “almost right” can work — but be more expensive to run and give poorer comfort over time.

Another mistake is not reviewing the home’s distribution system. If radiators, flows or settings don’t match the heat pump’s operating style, you may need higher temperatures than necessary and get lower efficiency.

Many also compare offers without comparing content: what’s included in pipework, startup, balancing, documentation and responsibility for drilling coordination.

Our focus is a solution that works in practice, is service‑friendly and delivers the savings you actually expect — not just a nice spec on paper.
