09/02/2012 Key considerations when planning for your new system

It's important when planning to have a Heat Recovery Ventilation System fitted in your home to consider the following steps, these will help you avoid some of the expenses, delays and pitfalls many renovators and self builders experience when they start a project unprepared!

Start as early as possible

The best way to ensure the smooth integration of an appropriate ventilation system into your self build is to consult a specialist team as early as possible, preferably during the planning stage.

Consider the system location

As well as considering which ventilation system you might use, you should think about where it will be positioned within your property, especially since planning regulations might dictate that certain conditions are met, such as the position of external terminals. Although modern systems are highly reliable and need very little maintenance, it's necessary to have access to the system for routine cleaning and servicing.

Know the rules

Although the legislation surrounding emissions and sustainability sometimes seems complicated and changeable, it's vital that you know your legal obligations and familiarise yourself with the latest or imminent legislation that might affect your self build. Think carefully about issues like planning permission, and remember that in built-up areas, near busy roads or airports that use of trickle vents may not be allowed. A reputable consultancy can help you navigate the rules and regulations relevant to your situation.

Choose carefully

Whoever you choose to supply your ventilation system, make sure you have chosen them carefully. It's worth remembering that an experienced and reputable team won't just design and install the very best system for your particular brief, they'll also project manage the process and ensure that the job's completed on time and on budget.

Finally ask yourself the following questions about your ventilation provider:

Are they TrustMark accredited?
Can they offer installation and commissioning of the system?
Do they specialise in working with self builders and renovators?
Will they provide truly impartial information and advice, or will they only recommend products and systems from a single manufacturer?
Are they members of HVCA, an association who monitor operating procedures and standards?
Do they know all the rules of ventilation? Too little ventilation leads to poor air quality and inadequate removal of pollutants and condensation. Excessive ventilation can cause discomfort through cold draughts and lead to increased heating costs.
Have they specified good quality ducting & accessories? The ductwork is an essential part of the system and must be of a standard that does not adversely affect its performance or lower your SAP rating.
