Ventilation and Heat Recovery Systems (HRS)

Heat recovery systems (HRS) are a type of ventilation that has a dual purpose, and are required for properties under Part F of Building Regulations. Depending on the type of property, you will need different ventilation and heat recovery systems, and this is something Point Electrical can advise you on.

HRS is a system for moving air around a property, pulling dirty air that’s full of contaminants like moisture, smells and other particulates from an area and pushing it outside. At the same time, HRS brings air in from the outside, and some of the warmth from air being expelled is transferred to the air coming in, helping keep the heat without the contaminants.

How Do Our Ventilation and Heat Recovery System Services Look?

Ventilation and heat recovery systems are found on the external walls of a building, usually at height but sometimes closer to the ground. This depends on the building and ventilation ducts installed during its construction.

HRS takes the form of a large box, or multiple smaller boxers, with motors in them to drive the transfer of air in and out of the property. They can be rectangular or round, depending on the needs of the building and specific piece of equipment installed.

What Types Of Mechanical Ventilation Do We Offer? 

Mechanical ventilation in a property can be broken down into a couple of categories. The broad umbrella term is mechanical extract ventilation, or MEV, and this is used by some businesses for both categories, which is confusing when trying to figure out which type you need.

The first category is centralised mechanical extract ventilation, or c-MEV. This unit sits in an area of the property that is connected to other rooms where moisture will gather regularly. It can be a cupboard with ducting or in the loft space. It runs continuously to make sure moisture doesn’t gather in excessive amounts anywhere in the property.

d-MEV, decentralised mechanical extract ventilation, is the second category and is placed in a room where moisture is expected to gather, such as kitchens or bathrooms. They are activated manually by a switch and switch off by the same switch or after a period of time.

Why Do Your Commercial Premises Require Ventilation?

Ventilation is required in most buildings, as stated in the Building Regulations, but depending on what the property is used for determines the kind of ventilation needed.

For commercial property, a continuous exchange of air minimises the risk of contaminants, which includes viruses and substances that can cause infection. The risk of spreading illnesses is higher inside, and workplaces see people from multiple households gather for long periods of time. This then can spread further.

Excessive moisture can also lead to damp and damage to the building, which is expensive to repair and resolve. Mental health is also improved by clean air and this improves the mood and productivity of staff. Finally, a good HRS can also reduce heating costs, which is a useful factor to consider.
