PRE-INSTALLATION CHECK LIST
Make sure that the unit can physically fit in to
the desired location.
The energiSava®250 unit should be
situated so that access for maintenance or
replacement of parts is possible. Make the
ductwork runs as short as possible. Having
the most direct route and using as few
bends as possible will reduce air resistance
and improve the efficiency of the unit.
SAFETY AND RECOMMENDATIONS
•All wiring must comply with Building
Regulations and the current I.E.E. Wiring
Regulations (BS7671) or the equivalent
standards for your country. The final
installation should be examined and tested
by a qualified electrician.
•The appliance is to be supplied through a
residual current device (RCD) having a rated
residual operating current not exceeding
30mA.
•Precautions must be taken to avoid the
back-flow of gases into the dwelling from
the open flue of gas or other fuel-burning
appliances.
•Make sure the mains supply complies with
the rating label for voltage, frequency and
phase.
•This appliance can be used by children
aged from 8 years and above and persons
with reduced physical, sensory or mental
capabilities or lack of experience and
knowledge if they have been given
supervision or instruction concerning
use of the appliance in a safe way and

Thank you for choosing EnviroVent
The fastest growing ventilation company in the UK
You are about to install a product that is designed to outlast the life-cycle of the building. Once
installed the unit will operate continuously for 5 years and beyond without a major service.
Please therefore ensure that this product is treated with care and installed properly i.e. for the
life of the building. If the unit is mishandled you might break it! This invalidates the warranty.
And remember, if you have any problems please call our dedicated Technical Team.
About the unit
The energiSava®250 is a whole house heat recovery unit which works by continuously extracting
stale, moisture-laden air from the “Wet Rooms” of the apartment or a house - the kitchen,
bathroom and en-suite rooms - and ducts this to a central unit. This extracted air passes
through a high efficiency counter-flow heat exchanger before being ducted to the outside.
Fresh air is drawn into the unit from outside, which is warmed by the heat exchange cell and
delivered into the living, dining and bedroom areas.
Made in Harrogate UK

Standard Features
Frost Protection
When the cell temperature in the unit falls
below 5°C the unit automatically warms
the cell with extracted air to prevent the
formation of frost.
Boost - Switch Live
The energiSava®250 comes with Switch
Live as standard. It is an automatic function,
sending the unit to boost when the bathroom
or kitchen light is on.
Summer Bypass
The summer bypass helps reduce the air
temperature coming into the dwelling during
the summer months. It is an automatic
function and operates when the supply air
temperature to the property is above 25°C.
Intellitrac®Humidity Tracking
When the energiSava®250 unit senses a
rise in humidity, caused by activities such as
cooking or showering, the extract and supply
airflows will slowly begin to increase in direct
proportion to the increase in humidity.
The airflows will automatically track back
down again when humidity falls. This controls
condensation quietly and efficiently.
Boost - Remote Control
The energiSava®250 unit also comes with
a remote control switch or app (model
dependent) which can be used at any time to
send the unit to boost (see page 12).

Ducting Configuration
See page 8 for duct
connections to the
unit/airflow directions
FIRST FIX - Installing ductwork and electrical supply
Important Note: This unit is for wall or floor mount only. Ceiling mounting unit are
configured differently and should be ordered separately.
1. Locate external terminations (supply and extract) in accordance with the latest addition of
the Domestic Ventilation Compliance Guide. Ducting to and from atmosphere needs to be
insulated in accordance with the Domestic Ventilation Compliance guide.
2. Ductwork within house Ø125mm - maximise duct size where possible. Make sure that the
ductwork is insulated in unheated spaces. Minimise flexible duct.
3. Locate the mains supply within 1m of the location of unit. The position of the electrical
power supply or unit (a fuse spur or triple pole isolator) must not be mounted above or
closer than 1m to a cooker where it could be affected by excessive heat or moisture.
4. Make sure that there is room for the MVHR unit. The unit is designed to be horizontally
mounted in a kitchen or utility cupboard (on the wall). It can also be floor mounted in a loft
space with an additional*drainage kit. EnviroVent Part number KIT-CONDENSATE-ES250-2.
5. Also make sure that there is a free space around the appliance for cleaning the filter and
carrying out maintenance on the appliance.

SECOND FIX - Installing the unit
1. Attach the wall bracket to a flat stable
surface that is capable of bearing the
unit’s weight, 14Kg. Ensure that bracket is
positioned so that there is enough space
for the condensate drain and ducts to be
connected. Fixing kit provided.
2. Attach spacers x 2 with screws provided.
The spacers ensure that the unit tilts to
improve drainage.
3. Slide the unit onto the wall bracket and
attach ducting and drain.
4. Tie down cable required for wall fit only.
Allow some slack in the tie down cable
when fitting.

is recommended. Insulate pipes in an
unheated loft space
Floor mounting
5. The unit can be floor mounted in a
loft space with an additional drainage
kit. EnviroVent Part number KIT-
CONDENSATE-ES250-2. Use the long and
short S brackets provided along with
short fitting screws to ensure correct

as here. The centre Tee section is reversed
to make either LH or RH drain. Push in the
drain fitting and seal as appropriate to
create a watertight assembly.
