Dual Geothermal Heat Pumps + Eco4 Light Floor Heating + EuroSmart 32 Zone Controls
1. Geothermal Boreholes & Piping
Three vertical boreholes supply 100% of the energy to geothermal heat pumps.
Each borehole 120 meters deep and connected to Energeo Manifold.
Energy supply constant and stable all year rounds to create maximum efficiency.
Geothermal manifold used to connect boreholes to heat pumps and share energy.
Geothermal Energy shared with two heat pumps increased efficiency.
Stable high efficiency all year round due to zero weather effect on performance.
2. Heat Pump Installation
Heat Pumps range in output from 3Kw of to 30 Kw using VSP Auto DRIVE.
System delivers - Heating - Cooling - Hot Water and hot water storage.
Main house and out offices heated from common plant room.
Thermal Energy Storage System used to deliver instant response.
32 zones control integrated with heat pump energy production.
3. Smart Energy Management & Distribution
Smart Control System EuroSmart direct energy to areas being used.
Automatic link to run pumps - valves and heat pumps when energy is requested.
Each zone has individual heat management and weekly schedule.
Pre-programming provider for 32 zones with individual tune and temperature settings for each zone.
4. Eco4 Radiant Floor Heating
Existing floors and floor screeds remain unattached.
Eco4 Radiant heating fits over any existing floor and transform it into a radiant heating system.
Radiators were removed from all rooms, with only low-temperature heating water required from heat pump.
Heat pump efficiency increased to up to 500% by the Eco4 system, achieved by lowering the required flow temperature.
5. Eco4 Screed Application
The Eco4 system was finished with a 25 mm high-conductivity to ensuring optimal heat transfer across all floor zones.
The low-mass screed delivers rapid warm-up times, stable temperatures and improved system responsiveness. Its smooth, durable finish provides an ideal surface for final floor coverings while maximising the efficiency of the geothermal heat pump system.
