Heat pump eciencies
COP – The ‘Coecient of Performance’ simply put is the relationship
between the power consumed by the appliance and the output in
heat. For example a 90% ecient gas boiler can produce 0.9kW of
heat from every 1kW of gas it uses, giving it a COP of 0.9. However,
under the correct conditions, a heat pump can produce up to 4kW
of heat from every 1kW of electricity it uses (giving it a COP of 4)
Glow-worm’s Clearly Heat Pumps range have COPs up to 4.06.
The compressor
The compressor is the heart of the heat pump which needs to be
protected. Some heat pumps such as the Glow-worm Envirosorb (for
Clearly Heat Pumps 7, 12, 14kW) have an inverter compressor which
means that the heat pump is able to modulate the compressor to
suit the energy needs of the home which helps to protect it coming
on, and going o frequently. An inverter compressor is essential on
larger output heat pumps to maximise the life of the appliance and
capitalise on the eciency of the system.

Refrigeration cycle
Using exactly the same principles as a fridge, the heat pump employs
the characteristics of a refrigerant. A fan draws air across a large
heat exchanger (or evaporator coil). As the refrigerant has a very low
boiling point, even in the depths of winter, this refrigerant is boiling.
The refrigerant passes into the compressor, where it is compressed
(think of the eect of a bicycle pump) to take it up to a temperature we
can use to heat the home.
The now hot gas passes into a plate heat exchanger, where it gives
up its heat to the heating system flow, whilst turning into a liquid.
With the hot system water now on its way round the heating system,
the refrigerant liquid nally passes through an expansion valve.
The expansion valve acts like an aerosol, turning it back into a low
temperature gas, to begin the whole process all over again.

System sizing
Functioning limits of the 7-14kW heat pump
during heating
Naturally, a unit that uses air as its source for heat, will perform better
as the temperature of that air increases. The industry standard for
quoting the output of heat pumps is Air 7/ Water 35. So, a 14kW heat
pump will deliver 14kW at an air temperature of 7°C when generating
a flow temperature of 35°C. Below are the outputs at various other
temperatures. The lower the flow temperature, and the higher the
ambient temperature, the more ecient they become: the system
should therefore be designed for as low flow temperature as possible.

For a design with a 45 degree flow temperature, such as underfloor
heating, or correctly sized radiators, the table below shows the
maximum size of a property each output is suitable for, based on
build year. Please note this does not take into account DHW.
These maximum sizes will ensure 100% coverage down to -5°C.
Pipe Sizing
Consideration needs to be given to the lower flow temperatures that
come from heat pumps, and also the smaller t required (5°C):
Typically systems from 4-10kW should be in 28mm. 10kW - 14kW
should be in 35mm (Some 14kW systems may require 42mm)

Minimum Clearances
5kW
7-14kW
Although these are minimum clearances, please note that the air
expelled to the front of heat pumps is extremely cold which needs to
be taken into consideration. As cold air sinks, placing an air to water
heat pump in a small, enclosed garden will chill the air available to
the unit, and impede its operation and eciency. Raising the units
slightly o the ground by using wall brackets or a stand will improve
the eciency.
The unit should ideally be:
• South facing
• Sited in a wide
open space
The unit should NOT be:
• Placed inside an
enclosed space
(e.g. a garage)
• Placed next to a fence

Flexible hoses to be used to avoid noise transmission.
Please note:
• Air source heat pumps do not fall within ‘permitted developments’,
therefore planning permission should always be sought
• Care should be taken to ensure condensate can drain away freely
• To avoid noise transmission from the unit into the home, flexible
hoses should be used immediately o the heat pump
• Connections to the rear of the heat pumps are 1” BSP male threads
• All external pipe work must be insulated to prevent heat loss
• To maximise eciency, distance from heat pump to the hydraulic
module should be as short as possible.
• The recommended Glycol solution of 30% will protect the heat
pump down to -15°C
• The 230V power cable to the heat pump should be 3 x 2.5mm² while
eBus and control cables should be 0.75mm².
• Heat pump should be raised suciently for condensate to drain
away without risk of freezing.

Note: The 3 port valve must be a 3 port diverter, and not a
mid-position valve. It must be installed, so that it powers
open the DHW circuit, and spring returns to close the
DHW circuit. (Suitable valve would be a Honeywell 4044c
reversed or similar).
A suitable 16A relay will be needed for the immersion
heater in the cylinder.
The cylinder should have 2 sensor pockets, top and
bottom, as control is done with 2 sensors. The top one
manages the immersion heater. The bottom one controls
the heat pump. Systempro intelligently uses both to
achieve maximum DHW performance, minimum re-heat
time, and optimum system performance.
Glow-worm’s Flurocyl twin coil cylinder range is suitable
up to 12kW. For the 14kW heat pump, a larger surface area
coil is necessary (ideally 3m of surface area).

The Envirosorb 5 heat pump is also available as part of Glow-worm’s
Cleary Hybrid system, which is the UK’s rst hybrid renewable domestic
heating and hot water system using advanced controls to select the most
cost eective method of heating at any time.
The Clearly Hybrid system combines the use of a High Eciency Glowworm boiler, such as the Ultracom with the Envirosorb 5 air to water
heat pump. The revolutionary heating system automatically selects when
to use low carbon renewable energy from the heat pump or traditional
energy from the High Eciency boiler, to always deliver cost eective
heating and hot water to your customers.
The Clearly Hybrid system provides a perfect solution for consumers and
organisations that are looking to use new, yet proven, technologies to
deliver cost eective heating and reduce their carbon footprint.
