compensation when combined with wireless outdoor sensor
Wireless outdoor sensor
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 eciency. The sensor is small and discreet, and no external wiring is required between the unit and the rest of the system.
Key features
Works on indirect sunlight,
which charges the inbuilt PV cells
No maintenance required
Simple and quick to install
Hydraulic Module SA
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 ll 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 buer vessels are required.
Dimensions
890mm x 418mm x 370mm
Key features

Heat pump eciencies
COP – The ‘Coecient of Performance’ simply put is the relationship between the power consumed by the appliance and the output in heat. For example a 90% ecient 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 eciency 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 eect 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.

Technical information 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 ecient 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 eciency. Raising the units slightly o the ground by using wall brackets or a stand will improve the eciency.
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 eciency, 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 suciently 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 eective method of heating at any time.
The Clearly Hybrid system combines the use of a High Eciency 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 Eciency boiler, to always deliver cost eective 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 eective heating and reduce their carbon footprint.
Key benets of Clearly Hybrid
Automatically chooses the most ecient fuel source - cost eective
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 Eciency 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*
