I installed the air conditioning of my house with a geothermal heat pump (iDM), underfloor heating, and photovoltaic panels with Energanova. We are very satisfied with the result. As a company they are very serious and professional, they advised me at all times. With this installation, the house is very comfortable and the consumption is reduced. It is a 100% recommended company.
What is underfloor heating?
Underfloor heating is the most efficient emission system and the most advisable to combine with a heat pump.
Underfloor heating/cooling
This is an invisible system. It consists of a network of pipes installed under the floor, through which hot or cold water circulates depending on the needs of the house.
The temperature is distributed evenly in all the spaces of the house. Thus, we achieve a comfortable room temperature at a lower operating cost.
TYPES OF UNDERFLOOR HEATING
- With mortar
- Without mortar
In most installations, this element is the mortar, which consists of a kind of cement that covers and surrounds the pipes. The final floor covering, which can be wood, ceramic, stone, etc… is placed on top of this cement.
This mortar should have a thickness of about 5 cm.
Dry underfloor heating consists of a layer of insulating panels on which the pipe network is placed. A metal sheet, usually made of steel or aluminium, is placed on top of them. This sheet is the one that acts as a conductive element. The final floor covering, which can be wood, ceramic, stone, etc., can be laid on top of this sheet.
Underfloor heating components
With mortar
Each circuit requires a certain amount of water flow, which they distribute based on demand. It acts as thermal and acoustic insulation. In addition, it serves as a guide for the placement of the piping.
These are plastic pipes that transport water along the surface to be air-conditioned (heating/cooling).
It is a foam strip that acts as lateral insulation for the edge of the panels and ensures the separation between the underfloor and the walls. Its purpose is to avoid thermal bridges, absorbing possible dilatations of the floor.
The insulating panel is the base on which the piping circuits are placed. It acts as thermal and acoustic insulation. In addition, it serves as a guide for the placement of the piping.
They are in charge of distributing the necessary water flow to each circuit according to the demand.
These are necessary elements to control the temperature in each of the rooms (thermostats, probes, etc.).

How does underfloor heating/cooling work?
- HEATING MODE
- COOLING MODE
When the system operates in heating mode, hot water circulates at a low temperature (28-38ºC/ 82-100ºF) through the pipe circuit. The heat is gradually transferred to the environment through the mortar layer and the screed. This way, the house is heated evenly with low consumption.
When an underfloor heating system operates in cooling mode, water is circulated through the pipes at a temperature of (13-18ºC/ 55-64ºF). This way, excess heat is absorbed from the room and the temperature is reduced until a feeling of comfort is achieved.
Advantages of Underfloor Heating Systems
By working with water circulating at a moderate temperature, significant savings are generated.
As it is under the pavement, it is an emission system that is not visible. You gain space and you are not conditioned to place your furniture.
Hot and cold spots in the house are eliminated. The feeling of comfort is homogeneous throughout the house.
The fact that the heat is distributed from the bottom to the top makes the thermal sensation pleasant.
Although its most common use is for heating, radiant floor can also be used for cooling by circulating cold water instead of hot water.
It can be used with different types of coatings, including wood.
The temperature regulation in the rooms can be controlled individually by several thermostats, placing one of them in each of the rooms.
No drafts are generated, thus improving comfort and preventing dust accumulation.

How much does underfloor heating cost?
Underfloor heating has become the most demanded emission system in newly built homes.
This has led to a great interest in knowing what the price of an installation with underfloor heating is.
The price of an underfloor heating installation is usually slightly higher than other emission systems. However, it has some benefits that justify this higher price. In addition to providing greater comfort, it has lower consumption. This means that the investment is amortized over a reduced period.
Underfloor heating price guide
To help you understand the price of underfloor heating, we have created this simple guide.
The price per installed m² (without mortar) is around 38€-46€/m² (if we only want heating), and around 40-48€ m² if we also want heating and cooling in summer.
You can find below a table of approximate prices depending on the use and surface area.
200m2: 46€
500m2: 42€
1000m2: 38€

Learn about the subsidies that are currently in force in our country for the installation of underfloor heating.
- Subsidies for self-consumption, storage, and thermal systems with renewable energies (RD 477/2021)
These aids approved by the government in June 2021 subsidize the new interior distribution of air conditioning, for the incorporation of underfloor heating for aerothermal and geothermal projects, provided that these systems work 100% with renewable energy: 600 €/kW up to a maximum of 3.600€.
These grants will be in force until December 31, 2023, but as has been the case in recent calls, the subsidies are non-competitive, that is, they will be processed in order of entry in the registry and until the credit is exhausted. Therefore, it is important to submit the grant as soon as possible.
The starting dates for submitting applications vary depending on the region.
