Heat
Recovery Ventilation System
Your home will
be well insulated and draught sealed to comply
with the New Building Regulations, but unless
you have effective ventilation, the air you breathe
inside your home may be up to ten times more polluted
than the air by a busy road. We will work with
our HVAC suppliers to install a full heat recovery
system designed for your property. Such systems
can benefit from upgrades such as climate cooling
or even air conditioning.
We spend a large
part of our lives at home. Keeping the air that
we breathe clean is therefore important, particularly
for certain vulnerable family members, such as
children and those suffering from respiratory
or allergic conditions. Almost a quarter of all
UK homes suffer from poor indoor air quality,
do you want your home to be one of them?
A
heat recovery system will keep your house ventilated
throughout the year, whist recovering the heat
already inside your home. It brings fresh air
from outside and recycles the otherwise wasted
heat from bathrooms and kitchen areas. Anywhere
where there is a high heat or moisture content
will be used to power the heat recovery unit and
keep efficiencies high.
How do Heat Recovery Systems work?
Step 1 -
Heat Recovery System
Dirty,
stale air is continually extracted from all the
wet areas, through unobtrusive white ceiling or
wall mounted extractors.
Step 2 -
Heat Recovery System
This
air then makes its way through the ducting and
the long rigid silencer, back to the heat recovery
unit. Before being discharged outside, it passes
through the plate or rotary wheel heat exchanger
giving up its heat to the cold fresh air coming
into the house.
Step 3 -
Heat Recovery System
The
highly filtered supply air is heated up to the
required temperature by the water heater coil
(linked to your wet heating system) or an electric
heater coil ensuring no cold draughts, which must
be avoided. The heat recovery unit controls the
extra heat requirements automatically.
Step 4 -
Heat Recovery System
The
supply air is now delivered through a long rigid
silencer into the supply ducting, through ceiling
or wall mounted supply registers, to all the habitable
rooms resulting in whole house heat recovery ventilation.
It is common practice
to have two or more heat recovery units working
in one large home and can be positioned to serve
zones or floors of their own. Ductwork can be
installed within Ecoweb or I joist floors so that
no boxing-in can be seen.
Nu Aire Heat Recovery
MVHR - Mechanical
Ventilation with Heat Recovery
Nuaire Home Ventilation produce a variety of mechanical
ventilation with heat recovery systems; from the
simplest of systems right through to the ultimate
in heat recovery with roof mounted solar collectors
and solar air/water heating and solar cooling.
The Facts
Regarding MVHR Systems
Will a mechanical ventilation with heat recovery
system save energy and money in a home compared
to other methods of ventilation? The short answer
is “Possibly”.
The level of effectiveness
in saving energy depends on a number of highly
variable and difficult to estimate factors. These
are the level of air tightness in a home, the
way the home is heated, the heat energy saved
by the system, the energy used by the system,
the type and cost of fuel used to heat the home
and the cost of electricity used to run the system.
Solo will work
with the Nuaire staff to advise you on all of
the aforementioned factors and help you make an
informed judgment on whether or not you should
install such a system.
The
importance of low noise levels.
MVHR systems are designed to run 24 hours a day,
seven days a week, 365 days a year. Quite simply
they have to be quiet in operation and acceptable
to the occupants. Nuaire Home Ventilation is renowned
for supplying systems with very low noise levels.
