Heat Recovery & Ventilation

 

At Grocon Energies we have built-up experience in the last several years in installing and commissioning balanced whole house heat recovery ventilation systems. We love these systems as they constantly provide clean, filtered warm air throughout the dwelling, satisfying all your ventilation needs while helping to reduce your heating bills.

We can offer you a choice on the manufacturer of your chosen heat recovery unit, whilst highly recommending both Domus and Vent Axia heat recovery units from our working experiences in the past. Both systems operate in the same principle, in a dual-flow capacity, ventilating the whole dwelling while reducing energy costs.

Provides quality, filtered fresh air evenly distributed throughout your home.

Reclaims thermal energy from extracted air whilst also removing moisture, odours and pollutants.

Reduces heating and cooling energy costs 

Numerous possible configurations 

Dual-flow ventilation enabling the fresh air to be blown into the living rooms (bedrooms, lounge, living room) and waste air extracted from the damp rooms (kitchen, bathrooms, washrooms).

A network of ducts enables air to be distributed and blown into the house.

The external fresh air is filtered and pre-heated by passing through a highly-efficient heat exchanger. This exchanger recovers the energy from the extracted air without mixing it with the renewed fresh air.

Domus heat recovery units improve indoor air quality through continuous balanced ventilation, throughout the whole house. They are easy and quick to install, commission and maintain.The Domus unit’s performance levels comply with current Building Regulation requirements while helping to reduce the Dwelling Emission Rate (DER) to secure additional SAP points. Through an efficient heat recovery process, it reduces household energy consumption.

Domus’ bluebrain controller uses advanced AMIE technology (Air Management for Indoor Environments) to offer simple pre-programmed functions, such as night-time cooling and intelligent thermal bypass while allowing for easy and straightforward commissioning and control.

Domus HRXD

Domus’ HRXD unit is recommended for smaller dwellings up to 150m². It is a highly intelligent and lightweight MVHR unit and its small size allows easier storage and installation. It can support the extract of a kitchen and up to five wet rooms.

Domus HRX2D

Domus’ HRX2D unit is recommended for larger dwellings rangingfrom 150m² to around 250m². It is a highly efficient and intelligent MVHR unit which is quick and easy to install and operate. It can support the extract of a kitchen and up to seven wet rooms.

Vent Axia Heat Recovery

 

The Sentinel Kinetic High Flow benefits from the latest high efficiency, backward curved impeller design, ensuring the lowest possible energy consumption, and an exceptional performance range covering small one bed apartments to the largest of houses.

The Sentinel Kinetic High Flow is ideal for larger homes and multiple occupancy units such as care homes and student accommodation. Capable of 175l/s at 150Pa, the unit can extract from up to fourteen bathrooms and a communal kitchen while still achieving almost 90% heat recovery. The fully automatic capability of the Kinetic range means that adequate ventilation is always achieved.

The integral humidity sensor increases speed in proportion to relative humidity levels, saving energy and reducing noise.

The sensor also reacts to small but rapid increases in humidity, even if the normal trigger threshold is not reached. This unique feature ensures adequate ventilation, even for the smallest wet room. The night-time relative humidity setback feature suppresses nuisance tripping as humidity gradually increases with falling temperature.

Features & Benefits - Vent Axia Sentinel Kinetic

 

  • Acoustic Enclosure option for reduced breakout noise
  • Acoustic Top Box option for reduced in-duct noise
  • Recognised in SAP PCDB
  • 180mm/200mm spigots
  • Horizontal duct option for space-saving installations
  • High airflow, ideal for student accommodation clusters
  • Unique folding filter for removal when access is restricted
  • Integrated digital controller for simple and accurate commissioning
  • Plug and play controls, Humidistat, Wireless Remote
  • BMS connectivity
  • LS inputs (Light Switch)

Installing a ventilation system in your home will allow you to..

  • Renew the air, eliminating humidity and odours
  • Ensure hygiene and comfort for the people in the household
  • Preserve buildings by preventing moisture development
  • Save the heating energy contained in extracted air

Whether you choose to install a dual flow ventilation or a heat pump water heater fed on indoor dumped air, Grocon Energies have solutions to match your need.

Did you know?

Contrary to what one might think, the air inside the home is more polluted than the air from outside, because stagnating, it loads up bacteria and dust.

Therefore it needs to be renewed continually to purify itself.The dual flow ventilation system takes fresh outside air, purifies it thanks to its high efficiency filters, and then diffuses it into the living areas of your home.

Thanks to its integrated heat exchanger, the dual flow ventilation recovers energy and calories from the exhaust air, allowing to preheat the fresh outside air, allowing you to save up to 20% on your heating bill.
