Solar Thermal Energy

High performance heat-pipe and vaccum tube

Produce 1000kWh/m²/year in North-West France

Example in LavalNorth-West France

• House in Laval– Domestic Hot water and house heating system– Analysis per year saving on gas invoice

50% saving in kWh/year

EPF (ENERGY PRODUCING FENCE)

- Premiere hot water producer with solar energy(Fengtech’s patent)

www.fengtech.fr

EPF has 4 functions 1 – Capture solar radiation for producing hot water (thermal energy). 2 – Controlling risk of summer overheating with integrated dissipation system 3 – In the winter, when the solar radiation is not enough, capture solar energy for a heat pump 4 – EPF is also an anti-intrusion fence

Capturing with a heat-pipe in vertical position

EPF’s challenges:

1) Produce thermal energy By solar radiation, giving a saving of more than 80% of primary energy, also to Reduce CO2 emission to zero

2) To optimize the capturing surface shape(less in summer and more in winter)

3) To minimize the ground installation Foot Print (vertical position)

4) Achieve a component durability of more than 30 years

5) Return on investment of less than 8 years
