Lorum ipsum dolor sit amet.

HES Energy is able to provide you with adaptable and innovative renewable energy solutions because we bring together our extensive experience in areas such as electrical, plumbing and ventilation.
At HES Energy, we provide a full range of adaptable services relating to:

HES Renewables Solar Water Heater

Solar Water Heating

Solar thermal systems use direct and indirect sunlight to heat water which is then stored in a hot water cylinder: they even work when the sky is overcast. On average, they can provide 60-70% of the hot water for Irish households. This system can have a payback period of between 6-11 years when switching from an oil based heating system.

HES Renewables Solar Voltaic

Solar Photovolteic Electricity

When light energy is absorbed by a semiconductor, an electrical charge is created. Photovolteic systems can be connected to the national grid – you are paid to provide electricity when producing surplus amounts, and “re-purchase” electricity in lag times. Batteries can also be utilised to store electricity for lag times.

HES Renewables Rainwater Harvesting

Rainwater Harvesting

Calcium-free rainwater is collected for use in toilets, washing machines or watering the garden, conserving drinking water. This decreases flood risks by offsetting the amount of run-off from developed land into rivers. Toilet flushing accounts for 30-40% of household and 80-90% of office water use.

HES Renewables Heat Recovery

Heat Recovery Ventilation

HRV allows the air inside a building to be replenished with fresh clean air while retaining the energy that would be lost through opening a window. They can also recover heat from exhaust air through a heat pump to heat water before releasing it into the open air.

HES Renewables Heat Pumps

Heat Pumps

Buildings can recover heat from exhaust air through a Heat Pump in order to heat water before releasing it into the open air. This system allows fresh air to be supplied to interiors while CO2, moisture and pollutants are removed, with the minimum of heat loss.

HES Emergency Callout

Repair and Emergency Call-outs

HES Energy have a full after-sales duty of care policy. We provide extensive repair and replacement services to all our customers and an emergency call-out service in case anything ever does go wrong.
