Air Source Heat Pump
INTRODUCTION
Your air source heat pump is designed to heat your home and
to provide domestic hot water (DHW). Your installer will have
ensured that your heat pump has sufficient heating output to
provide these services without any supplementary heating
being required. The heat pump uses refrigeration technology to
extract heat from the outside air at temperatures down to -15
producing as much as four times as much heat energy as the
electrical input required to drive it. This results in an efficient
low cost, low carbon, heating system.
HEATING SYSTEM CONTROLS
The heat pump is designed to operate with a standard heating
programmable controller linked to a room thermostat, providing
space heating or DHW according to demand. The unit has two
modes of operation, one for space heating through under floor
heating or radiators adjustable between 35
second for DHW preset at 65
review the electricity tariffs from all suppliers in your area and
select that which will give you the optimum economy in relation
to your lifestyle and heating demand. Timings appropriate to
your heating and hot water demand and to the selected tariff
should be programmed into the controller.
We recommend that you set your programmer to heat the hot
water for 1 ½ to 2 hours before you require it first thing in the
morning or later in the day. A typical winter heating programme
is illustrated below.

OPERATING THE HEAT PUMP
When setting the programmer, allow extra time for the heat
pump to raise the water temperature when first switching on,
as it will take longer than a traditional boiler to reach the full
operating temperature.
Because a heat pump operates in heating mode at a

linked to a gas or oil boiler traditionally supplying water at 80
Your installer will have ensured that your radiators are correctly
sized for operation with a heat pump but you may also notice
that they remain warm for longer periods rather than cycling on
and off as is the case with traditional boilers.
The heat pump supplies domestic hot water at 65
stored in the special hot water cylinder provided with your heat
pump to ensure that you always have hot water on tap. The
temperature of the stored hot water is controlled by the cylinder
thermostat and you should set this at a level which gives you
hot water at a temperature which suits you.
