What features does my Loft Unit have?

The intelligent low temperature comfort heater* is designed to temper the air during periods of low
external temperatures. It is capable of holding incoming air temperatures accurately at 10°C. With the
function enabled, the heater may be on 10% of the time, depending on the fan speed setting and only
at loft temperatures at or below 10°C.
When the input air temperatures rises above 25°C, the unit will temporarily shut down the supply, to
avoid bringing hot air into the property.
The units have an automatic increased airflow setting. This function increases airflow rates per setting
by 10% to deliver additional air into the property at temperatures above 19°C.
*Heater may be omitted on request by the customer.

Maintenance

The Loft Units have been subjected to rigorous testing and are constructed from durable materials.
There should be no requirement for any maintenance within the five year period.
At the five year service, the loft filter located on the unit must be replaced to ensure maximum efficiency
of the unit. The filter is mounted around the unit with velcro, simply pull off and replace.

How much does my Loft Unit cost to run?

The Loft Units are very energy efficient. On a constant medium setting with the heater enabled, the
unit will cost around £30* a year to run. With the heater disabled the unit will cost less than £6* a year.
*Based on an average electricity unit price of 15p.
Costs will vary year on year depending on atmospheric conditions and unit settings.
