Heat Pumps in Low-Carbon Context

Lesson

Heat pumps in low-carbon heating

A broad introduction to heat sources, electricity use and the conditions that support good performance.

Solar Thermal Hot Water

Lesson

Solar thermal hot-water principles

Collector, circuit, cylinder and control functions with frost, stagnation and backup-heat awareness.

The Move to Low-Carbon Heating

Lesson

Low-carbon heating context and options

Compare fabric measures, heat pumps, heat networks, solar input and biomass without treating one technology as universal.

Integrating Low-Carbon Heat

Lesson

Integrating low-carbon heat into a home

Bring heat loss, emitters, stored hot water, hydraulics and controls into one workable system.

Low-Carbon Design Awareness

Lesson

Heat-pump design warning signs

A short awareness guide to evidence a specialist heat-pump design should contain.

MCS Certification & Low-Carbon Funding

Lesson

MCS certification and low-carbon funding

What MCS is, why it matters, and how funding like the Boiler Upgrade Scheme fits in.

Low-Carbon Hot Water

Lesson

Hot water with a heat pump

How a heat pump heats stored water, the Legionella point, and the role of the immersion.

Biomass & Other Low-Carbon Heat

Lesson

Biomass heating practical considerations

Fuel storage, feed, combustion, buffer storage, ash, flueing and maintenance in biomass systems.

Future Fuels & Heat Networks

Lesson

Future fuels and heat networks awareness

Use precise language for hydrogen proposals, heat networks and future-ready claims.

Sustainability & the Environment

Lesson

Sustainable heating decisions

Assess demand, whole-system performance, refrigerant, materials and waste across the installation life.

Solid Fuel & Biomass Safety

Lesson

Solid-fuel and biomass safety basics

Combustion air, flueing, hearths, fuel, maintenance and carbon monoxide precautions.

Compare heat sources with the building and system in mind

Start renewable-heating revision with the demand the system must meet. Compare how heat is produced, distributed and controlled, and identify which assumptions a proposed change relies on. Equipment labels alone cannot establish suitability for a particular home.

Use the air-source heat-pump notes for a closer look at the refrigeration cycle and system design. The radiator output calculator illustrates why the same emitter has different outputs under different operating temperatures.
