Water Radiators are an almost indispensable element in homes worldwide, as this home heating system allows us to warm or maintain the temperature in our residence without significant effort or high monthly bills.

Water radiators operate by being distributed throughout the home and are supplied with hot water from a piping system, which is in turn fed by a boiler, gas heater, or electric water heater. This setup, along with a circulating water pump, allows the hot water to be pumped throughout the system, heating all the water radiators in the home.


Why Buy Water Radiators

If you decide to install water radiators at home or wish to replace existing ones, here are several reasons why you should consider purchasing them:

  • Greater efficiency compared to other systems
  • Energy and cost savings
  • Greater durability than other heating options
  • Modern designs suitable for any home
  • More uniform heat distribution
  • Silent operation
  • Better air quality without dryness


What Types of Water Radiators Exist?

Currently, we can purchase a wide variety of water radiators for our home, which can be distinguished by their manufacturing material, installation arrangement, or operating temperature.

Cast Iron Radiators

Currently, this type of water radiator is in decline due to its outdated design and incompatibility with modern installations, given its bulk and low heat output. Cast iron radiators have high thermal inertia, great resistance to impact, and corrosion tolerance, although they can be inefficient and challenging to place in the home.

Aluminium Water Radiators

This option is the most commonly used today due to its low cost, high energy efficiency, and ease of installation in any home, as its compact size can heat a room effectively. Aluminium water radiators are a great option to consider if you have limited space and want to save money on installation.

Steel Water Radiators

This type of radiator emits most of its heat through radiation, making them the least efficient, along with being slightly more expensive than aluminium ones. Steel water radiators are a minority choice, but not discouraged, as they are available in various sizes.


Water Radiator Designs

If you are thinking of replacing water radiators in your home or installing new ones, you should consider which design to choose. We offer flat water radiators and ultra-flat water radiators, and you should select the one most suitable for your home.

Flat Water Radiators

This option is the most common in radiator installations, as they tend to be low-cost or reasonably priced, with designs suitable for all types of installations. Flat water radiators are the traditionally chosen option in all homes, made of aluminium, and usually feature a smooth front for a more aesthetic design and better heat retention with less dispersion.

Ultra-flat Water Radiators

If you are looking for a radiator with an innovative and modern look, especially designed for very small spaces or to occupy the least possible space, ultra-flat water radiators are the right choice if design is a priority regardless of price. It is worth noting that ultra-flat radiators are typically powered by electricity rather than hot water due to their ultra-flat size.


How to Choose Water Radiators for Your Home

When you decide to install water radiators at home, it's time to think about how and which ones to choose for the different rooms and spaces in your home, as there are many models with various elements, materials, and designs.

1. Know the m2 to Heat

When selecting radiators for your home, you need to know the square metres you want to heat, as this will make it easier to choose between the different options available.

2. Select the Elements You Need

Once you know the square metres each radiator needs to heat, it's time to choose the appropriate elements to ensure adequate heating. Choosing too many or too few can result in excess heat or insufficient warmth, so it's important to follow the calculations provided in our guide to determine the elements needed per square metre.

3. Choose a Design to Suit Your Taste

It's essential to have a design that fits your home and personal taste, as they will be installed on the wall for many years and become part of the room or space where the water radiator is installed.

4. Check the Distance Between Axes

To ensure that the connections in your home are compatible with the new radiators you will install, you must ensure that the chosen option has the appropriate distance between axes. Each product includes its various dimensions to make this final step straightforward and provide the best heating for your home.


How Many Elements Should Water Radiators Have?

The elements of a radiator should be chosen based on the area to be heated, as the number of elements needed will depend on the square metres to be heated to complete the radiator set for your home. Generally, there is no rule for determining the number of radiator elements per room, so we recommend contacting our expert team. However, here are some tips regarding the different elements.

Water Radiators with 1, 2, 3 Elements

To heat a small room of up to 10/15 m2, water radiators with 1 to 3 elements will suffice, as a large installation is not needed for a small space.

Water Radiators with 4, 5, 6 Elements

If you have a larger area, such as a living room, a room of up to 30/40 m2, or various large spaces in your home, you should opt for this option, which will allow you to heat your home comfortably and economically with a single radiator for the entire space. Water radiators with 4, 5, 6 elements are available in this section with different designs and features for installation.

Water Radiators with 7, 8, 9 Elements

Water radiators with 7 to 9 elements can heat a home space such as suite rooms, dining rooms with open kitchens, and open spaces without losing temperature or overloading the boiler. This number of elements allows for efficient home heating.

Water Radiators with 10, 11, 12 Elements

This type of radiator, with a large number of elements, is suitable for more industrial installations, offices, or schools, as a sufficiently large space is needed to take advantage of the qualities of radiators with a high number of elements.
