How Eco4 Works?
Unlike conventional heating systems that rely on convection to distribute the heat, Eco4 uses low-intensity radiant rays to heat the occupants. Operating at low temperatures in a thin 25 mm to respond system responds quickly without heat loss in occupied areas and avoids heating the high space at the ceilings.

Designed for Heat Pumps
Eco4 operates at low water temperatures, making it an ideal partner for heat pump technology, this improves system efficiency and reduces running costs, supporting the transition away from fossil fuels.
Retrofit Friendly
Eco4 Light can be installed directly onto existing timber or concrete floors, a practical solution for renovation projects. Older buildings benefit from renewable heating technology, no structural alterations and much lower heating cost.
Heritage Buildings
Eco4 is particularly suitable for heritage and protected buildings where major fabric changes are restricted. The system operates at low temperatures while maintaining comfortable indoor conditions and helping to improve the overall energy performance.
Comfort Cooling
When connected to a heat pump, Eco4 can also provide comfort cooling. The floor absorbs excess heat from the room, creating a comfortable indoor environment during warmer months without the discomfort associated with air conditioning.
Eco4 Instant heating – Compared to UFH
The key difference between Eco4 and standard underfloor heating is the 25 mm screed performance.This cuts the warm-up time, improves responsiveness, limits energy requirements, and delivers consistent comfort with radiant heat.

Your Project: 10 Steps to Comfort
From first contact to warm floors – our proven process.
Once you have decided on the areas you intend to heat or if it is the entire project, simply forward a set of floor plans with clear instructions and our design teal will do the rest.
Our engineers survey the plans, select the most suitable location for equipment, agree locations and design the Eco4 system.
Images to accompany plans on retrofit projects are beneficial to our design engineers in locating the Eco4 manifold.
Architectural features that may affect the installation can be highlighted and discussed to accommodate same.
Final detailed plan and layout diagram provided for agreement prior to costing the system or dispatching product.
Cost estimating:
Eco4 RADIANT is best costed by providing a floor plan for the area intended.
A comprehensive list of equipment is generated to establish the cost.
New construction projects should plan early in the process to take advantage of cost reductions created by Eco4 radiant in the overall budget.
Domestic projects can also reduce costs, finished floor and subfloor screed can be combined into one, first floor will not require insulation, first or second floors decked in timber are ideal for Eco4 LIVING.
Instalation time to install the system is reduced, screed thickness is reduced, drying out time is reduced, warm up time is instant.
Design, supply and fit options, provide a clear breakdown of costs, fitting time, and screeding option if required.
All Eco4 LIVING forms part of a renewable energy package with grant aid up to 40% available due to its effect on increasing system efficiency and operating cost.
There are two ways to precure the Eco4 Light system, one option is to source the system materials, supply only and engage an experienced installer to fit and commission the system on site. This option can include a system design document which can be provided following receipt of the required project information.
Alternatively, the Eco4 LIVINGis offered as a design, install and commissioned system. Once the design is approved, you can procure the necessary equipment, consult with the project manager, agree the instalation date and receive instructions required to prepare the site. Once the instalation date is agreed with the installation team preparations are in train to ensure a smooth and efficient installation process. Regularly communicate with the team is advised to update on project progress and align with the plan.

TESTIMONIALS
I choose Eurotech to install my geothermal heating & EuroSmart controls due to their reputation & I wasn’t disappointed.
I am very happy with the system. They are clearly committed and dedicated. If I could give the team more than 10/10 I would.
The whole system is very easy to manage; I like how I can control each room from the main office and lock out sensors…
One of the selling points for me was the ease at which the system can be used and it is so economical.
It’s trouble free as far as I’m concerned, I found Eurotech very helpful, only a phone call away and always a prompt response.
Our residents love the constant temperature & their ability to control the temperature in their own rooms.
The system is very simple to operate and I find that the high level of insulation in the house compliments the overall solution.
