Do you have solar panels but feel like you’re giving energy away to the grid? It’s the dilemma facing today’s solar power users: your panels produce the most electricity at midday, when you may not be home. That’s where photovoltaic surplus management comes in—a strategy that turns your solar installation into a powerful way to
One of the most common concerns when considering an air-source heat pump is whether it can heat existing radiators. The short answer is yes, but there are technical considerations worth understanding before accepting a quote. In this article, we break down the physics of the problem, the flow temperature aluminum radiators require, and which models
Can you imagine enjoying a swim in 28°C water in April or late October without worrying about your electricity bill? In 2026, technology means we no longer have to depend on sunshine or expensive electric heaters. The answer is beneath your feet: geothermal pool heating. Thanks to the stable temperature of the ground, you can
Have you wondered how much you’ll pay for heating this winter? In 2026, efficiency is no longer an option—it’s a necessity. We put two giants of sustainable heating and cooling head to head: pellets vs. air-source heat pumps. We analyze real bills for a 150 m² detached home so you can find out, once and
When it comes to decarbonizing a home, the question is no longer whether to install a heat pump, but where to draw the energy from: the air or the ground? Although both technologies are pillars of the energy transition, their performance depends on a fundamental physical variable: the stability of the energy source. In this

If you’re thinking about replacing your old oil or gas boiler, you’ve probably heard the claim: “Air-source heat pumps only work with underfloor heating; if you have radiators, they won’t work for you”. We have good news: that claim is outdated. Thanks to technological advances and the use of new refrigerants, it’s now entirely possible
High-Temperature Air-Source Heat Pumps: Can You Really Keep Your Old Radiators? Read More »
In today’s energy landscape, the term “Zero Bill” has ceased to be a utopian idea and become a technical reality. It is not simply a matter of installing solar panels, but of implementing an intelligent ecosystem in which air-source heat pumps and solar PV work in sync under an advanced management system. In this article,
Heating and cooling a detached home in Spain presents one of the greatest energy challenges for homeowners. Large floor areas, high ceilings, and the need to maintain comfort year-round can drive up energy consumption. However, there is a solution that combines sustainability, efficiency, and long-term savings: installing geothermal heat pumps alongside photovoltaic solar panels. In
Geothermal energy is becoming one of the most efficient solutions for heating and cooling homes and buildings in Spain. However, one of the key steps before installing a geothermal heat pump is deciding between a vertical and a horizontal system, as each has different technical, regulatory, and financial requirements. In this comprehensive guide, we examine
The transition to more sustainable refrigerants is a reality in the HVAC sector. In 2025, R290 (propane) has become the leading refrigerant for high-efficiency air-source heat pumps. Its adoption is driven by European regulations on fluorinated gases (F-Gas), the pursuit of greater energy efficiency and the need to reduce CO₂ emissions. At Ecoforest, we have

Air-source heat pumps are transforming heating and cooling in Spain, but when it comes to older flats with traditional radiators, many questions arise: Will a heat pump work? What flow temperature do I need? How much electricity will it actually use? Do all the radiators need replacing? In this article, we answer these questions with
Combining an air-source heat pump with solar PV and batteries is accelerating the shift towards full self-consumption: heating, cooling and domestic hot water (DHW) powered by renewable energy, less dependence on the grid and lower bills. At Ecoforest, we integrate the entire ecosystem (ecoAIR+, ecoGEO+, surplus energy management and storage) to make the system truly
