The Ezy-Warm Heated Mat’s ultra-thin profile means that it is very energy efficient.
In conventional systems, the heat source is buried under extra layers of adhesive and material, which the heat energy has to pass through and heat before heating the top flooring surface. This uses excess heat energy and cost.
Independent testing using Dynamic Building Simulation* has demonstrated the reduction in running costs achieved using Ezy-Warm Undefloor Heating versus conventional heating methods.

* Details of Test Method Used
DSM is an engineering software solution, that runs complex dynamic calculations and uses vast amounts of data from building models to provide predictions of how a building will perform.
Simulation Tool
DesignBuilder is a whole building energy simulation program used to model energy consumption with the EnergyPlus methodology-for heating, cooling, ventilation, lighting and plug and process loads. Some of the notable features and capabilities of DesignBuilder are:
Integrated, simultaneous solution of thermal zone conditions and HVAC system response that does not assume that the HVAC system can meet zone loads and can simulate conditioned and under-conditioned spaces.
Heat balance-based solution of radiant and convective effects that produce surface temperatures thermal comfort and condensation calculations.
Sub-hourly, user-definable time steps for interaction between thermal zones and the environment; with automatically varied time steps for interactions between thermal zones and HVAC systems. These allow Energy Plus to model systems with fast dynamics while also trading off simulation speed for precision.
Combined heat and mass transfer model that accounts for air movement between zones.
Models
Sample 3D models of each building type were created for this project. All models are based on buildings designed to current building regulations and are used by the software to calculate the heating load, based on the building geometry, construction, building services, activity data, and the climate file.
