Introducing Glow-worm's complete
range of straightforward air to water
heat pumps
System components
Envirosorb 5
(for Clearly Heat Pumps 5kW)

Hydraulic Module SA
Climapro₂ RF
The Hydraulic Module contains the
circulating pump, which transfers
the heat generated by the heat
pump into the heating system.
It also separates the heat pump
circuit from the central heating
circuit meaning that you don’t
need to fill the whole system with
glycol anti-freeze. The Hydraulic
Module in itself is compact and
easy to install, as no separate
expansion vessel or additional
buffer vessels are required.
Glow-worm’s most intuitive and
user friendly control;
Climapro₂ RF is the main point of
interaction with the system for the
homeowner. The handheld control
enables homeowners to simply
and quickly programme their
specific heating and hot water
requirements in detail, from the
comfort of their armchair.
Dimensions
890mm x 418mm x 370mm
Key features
•Single indoor unit
•6 kW variable immersion
heater to ensure maximum end
user comfort
•Incorporates two three way
valves for easy filling of the glycol circuit
Key features
• Wireless, programmable room
thermostat for complete time
and temperature control
• Large backlit display
• Handheld unit, can be wall
mounted or taken around the
home
• Provides room and weather
compensation when combined
with wireless outdoor sensor
Systempro
Wireless outdoor sensor
The Systempro acts as a central
installer
interface,
where
maintenance menus, fault history,
system parameters, etc. can all be
programmed and accessed.
The Glow-worm wireless outdoor
sensor intelligently communicates
the outside temperature to the rest
of the system to provide weather
compensated flow temperatures
for maximum efficiency. The
sensor is small and discreet, and
no external wiring is required
between the unit and the rest of
the system.
Dimensions
290mm x 264mm x 45mm
Key features
• Intelligent wiring centre for
the system
• Central installer interface
• No need for end user
interaction
• Can be used to control a multi-zone system
Key features
• Works on indirect sunlight,
which charges the inbuilt
PV cells
• No maintenance required
• Simple and quick to install

Clearly Heat Pumps
Technical information
Heat pump efficiencies
COP – The ‘Coefficient of Performance’ simply put is the relationship
between the power consumed by the appliance and the output in
heat. For example a 90% efficient 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 Envirosorb₂ (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 off frequently. An inverter compressor is essential on
larger output heat pumps to maximise the life of the appliance and
capitalise on the efficiency 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 effect 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 finally 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.

Technical information
System sizing
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 efficient they become: the system
should therefore be designed for as low flow temperature as possible.

Technical information
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 Δt 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
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 efficiency. Raising the units
slightly off the ground by using wall brackets or a stand will improve
the efficiency.
P
The unit should ideally be:
•South facing
•Sited in a wide
open space
O
The unit should NOT be:
•Placed inside an
enclosed space
(e.g. a garage)
•Placed next to a fence

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 off 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 efficiency, 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 sufficiently for condensate to drain
away without risk of freezing.

Clearly Heat Pumps including DHW
The wiring of the relay to the Systempro
22
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.

Clearly Hybrid system
The Envirosorb 5 heat pump is also available as part of Glow-worm’s
Cleary Hybrid system, which is the UK’s first hybrid renewable domestic
heating and hot water system using advanced controls to select the most
cost effective method of heating at any time.
The Clearly Hybrid system combines the use of a High Efficiency Glowworm boiler, such as the Ultracom₂ 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 Efficiency boiler, to always deliver cost effective
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 effective heating and reduce their carbon footprint.
Key benefits of Clearly Hybrid
•Automatically chooses the most efficient fuel source - cost effective
operation and lower carbon footprint
•One complete package: heat pump, hydraulic module and control easy to install and commission
•Use with any new Glow-worm High Efficiency boiler: combi, system
and open vent models
•Includes Glow-worm’s high performance Envirosorb 5 air
source heat pump
•Full system with clear and simple operating controls
•Can achieve over 40% carbon savings*
*When replacing an older, standard efficiency boiler
