Homeowner’s User Instructions
Introduction
The Ecodan air source heat pump extracts thermal energy from the outside air and transfers this into a property
in the form of hot water as a conventional heating system does. The Ecodan will provide space heating (through
radiators or under floor heating) and domestic hot water (taps, showers, etc). Domestic hot water always takes
priority over space heating.
The Ecodan Aerocyl Plus-me package is controlled by conventional heating system control equipment. A two
channel time clock for ON and OFF periods, a cylinder thermostat for domestic hot water temperature and a
room thermostat for space temperature.
To optimise running costs it is advisable the homeowners seek the cheapest possible electricity tariff.
An internet search facility like www.uswitch.com will be able to help.
The homeowner will need to control the Ecodan Aerocyl Plus-me differently to a conventional gas boiler.
The use of controls is paramount in achieving low running costs. Although electricity prices are higher than
gas or oil, the efficiency of the system means that it requires less energy to supply the same heating demands,
thus producing cheaper energy bills. Compared to regular electricity bills it will look higher than usual, but the
homeowner should be aware that this bill incorporates heating that is usually achieved though gas or oil.
Please note that heat pumps provide lower flow temperatures to radiators than a conventional gas boiler.
Rather than the radiators turning on/off locally as with a gas boiler, heat pumps provide a more consistent lower
flow temperature which allows for more efficiency and greater comfort.
