Knowledge
We are delighted to share our knowledge. Have a look below to learn more about the underlying technical principles of what we do and the physics that allows these systems to work.
How do air-source heat pumps work?
A plain-English guide to how an air-source heat pump moves heat out of outdoor air to warm a building, and why it uses so little electricity to do it.
Read moreHow do ground-source heat pumps work?
A plain-English guide to ground-source heat pumps: how buried pipes collect heat stored in the ground, and what it takes to design and install one well.
Read moreThe difference between air-source heat pumps and ground-source heat pumps
Air-source and ground-source heat pumps work the same way but take heat from different places. Here is how they compare on efficiency, space, disruption and running.
Read moreSolar photovoltaics: what are they and how do they work?
A plain-English guide to solar photovoltaic (PV) panels: how sunlight becomes electricity, what affects how much they produce, and how they fit into a wider energy system.
Read moreEnergy storage systems for home and industrial use: how they work and what they do
A plain-English guide to battery energy storage: what is inside a system, what it can be used for, and how to think about size, battery type and safety.
Read moreElectrical containment systems: what they are and why they matter
A plain-English guide to electrical containment: the trays, trunking, conduit and brackets that carry and protect cables, and why doing it well makes a building safer and easier to look after.
Read moreWhat is a ducted fan coil unit (FCU)?
A plain-English guide to ducted fan coil units: what they are, how they heat and cool a room through hidden ducts, and when they are the right choice.
Read moreWhat is a wall-mounted fan coil unit?
A plain-English guide to wall-mounted fan coil units: the familiar indoor units that heat and cool a single room, how they work and when they make sense.
Read moreCompressor and condenser heat pump systems explained
A plain-English guide to the main parts of a heat pump, the compressor, condenser, evaporator and expansion valve, and how split and monobloc systems arrange them.
Read moreU-values explained: why they matter in building and heating design
A plain-English guide to U-values: what the number means, how it describes heat escaping through walls, roofs, floors and windows, and why it shapes heating system design.
Read moreHow heating and cooling affect buildings with different U-values
A plain-English look at how well-insulated and poorly insulated buildings behave when heated and cooled, and what that means for heat pump design.
Read moreSolar gain and how it affects air-source heat pump design
A plain-English guide to solar gain, the heat that sunlight adds to a building through its windows, and why it matters when designing heat pump heating and cooling.
Read moreSeasonal variation: solar generation versus heat pump electricity use
A plain-English look at why solar panels produce most in summer while heat pumps use most in winter, and how a well-designed system deals with the mismatch.
Read moreThe UK government's Be Ready campaign and what it means for your property
What the UK government’s Be Ready campaign asks people to prepare for, and how changes to a property can help it keep running without power, water or internet.
