Renewable Technology

Benefits Efficient - For each 1 kW of electricity, you get 3–4 kW of heat. Low‐carbon - Cuts emissions compared to gas or oil. Versatile - Heats your home and hot water. Some systems can cool too. Reliable - Works well even in cold climates. How they work Heat pumps warm your home by pulling heat from the air or ground. They use less energy than a boiler. They cut carbon. They keep your home warm, even in cold weather. The system pulls heat from the air. A compressor boosts this heat using a small amount of electricity. The heat passes into your home to warm rooms and hot water. The cycle repeats to keep your home at a steady temperature. Air Source Heat Pumps An Air Source Heat Pump takes heat from the air outside and uses it to heat your home. It works in winter, even in freezing conditions. It runs on electricity and produces far more heat than it uses.

Benefits Energy‐efficient - The heat pump handles the majority of heating. Reliable - The boiler ensures heat during extreme cold. Cost‐effective - Reduces energy bills by using the best fuel at the right time. Eco‐friendly - Cuts carbon emissions. How they work Heat pump (primary source) Works like a reverse air conditioner. Pulls heat from outdoor air, even when cold. Runs efficiently in most weather. Boiler (backup) Switches on when the temperature drops too low for the heat pump to run efficiently. Uses gas, oil, or electricity. Smart controls Sensors and thermostats decide when to switch between the heat pump and the boiler They check the temperature, running cost, and efficiency The system chooses the cheapest and most efficient option Hybrid Heat Pump Hybrid systems pair a heat pump with a boiler. The heat pump does most of the work. The boiler steps in only when needed.

Benefits Very efficient - produces 3–4 units of heat for every 1 unit of electricity. Low carbon - even lower when powered by renewable electricity. Low running costs - cheaper to run than gas or oil once installed. Long lifespan - ground loops can last more than 50 years. How they work A buried loop of pipes holds a water–antifreeze mix. The ground stays at a stable temperature all year. As liquid circulates through the loop, it absorbs natural heat from the earth. The warm liquid enters the heat pump. A compressor boosts the temperature. It works like a fridge, but in reverse. The system sends heat to radiators, underfloor heating, and hot water. Ground Source Heat Pump (GSHP) A Ground Source Heat Pump (also called a geothermal heat pump) uses the steady warmth stored in the earth to heat your home.

Benefits Energy savings - Recovers up to 90% of heat that would otherwise be lost. Better air quality - Provides a steady flow of filtered fresh air. Humidity control - Helps stop condensation, damp, and mould. Comfort - Maintains balanced temperatures and removes draughts. Mechanical Ventilation with Heat Recovery (MVHR) Mechanical Ventilation with Heat Recovery (MVHR) brings fresh air into your home and removes stale air. At the same time, it recovers heat that would normally escape. This makes your home warm, efficient, and well‐ventilated. MVHR works best in modern, airtight homes. How they work Removes stale, moist air from kitchens, bathrooms, and utility rooms. Pulls in fresh outdoor air at the same time. Transfers heat from the outgoing air to the incoming fresh air without mixing the two. Sends warm, filtered air to living spaces like bedrooms and living rooms. Keeps your home comfortable, dry, and energy efficient.

Benefits Efficient - Heats objects directly, so less energy is wasted heating the air. Fast - Provides almost instant warmth. Silent - No fans or moving parts. Clean - No emissions or combustion. Comfortable - Creates a natural, sun-like warmth. Uses Homes and offices - wall or ceiling panels. Saunas - for their deep- penetrating heat. Outdoor patios. Infra-red Heaters Infra-red heating uses infra- red radiation to warm objects and people directly, rather than heating the air around them.

Benefits Lower electrical bills- They generate free energy and can save you £100s a year on electricity bills. Increased property value- Homes with solar sell for about 4% more on average. You can get paid to export electricity you generate. How they work Solar panels capture sunlight using cells on their surface. These cells turn sunlight into electricity. The electricity is then used within your home. Any extra electricity produced can be stored in home batteries or sent back to the grid. Solar PV Panels Photovoltaic panels, or solar panels, take the sun’s light and turn it into electricity. It happens through a simple process called the photovoltaic effect.

How they work Charging Solar panels make electricity during the day. Extra energy is stored in the battery instead of going back to the grid. The battery can also charge from the grid when electricity is cheaper. Storage The battery holds the electricity until you need it. Using the energy When your home needs power, the battery supplies it (e.g. During the day or during a power cut). An inverter changes the electricity into a form your appliances can use. Benefits Energy independence- Use your own power even when the grid is down. Lower bills- Store cheap or free electricity and use it when prices are high. Eco-friendly- Maximise your use of renewable energy. Home Battery A home battery holds power so you can use it when you need it: During a power cut (if the system has this option) in the night. When the price of electricity climbs. It is often paired with solar panels but can also store energy from the grid.

How they work Charge at night The heaters use cheaper, off-peak electricity overnight. This electricity heats internal ceramic bricks that store heat for many hours. Releasing heat during the day The stored heat is then slowly released throughout the day. Fans and thermostats help to control how much heat is given off and when. Smart controls Many modern heaters have digital timers, sensors, and Wi-Fi. They can learn your routine and adjust heating automatically. Some models respond to weather forecasts or electricity prices. Benefits Energy-efficient - Better insulation and control reduce waste. Cost-effective - Uses cheaper nigh- time electricity. Flexible - More control over when and how much heat is released. Low maintenance - No moving parts or fuel supply is needed. Storage Heaters

How they work Connection to power source The charger is connected to the electric grid (home, workplace, or public station). It then draws electricity and delivers it to the EV through a charging cable. Communication with the vehicle When you plug in the charger, it communicates with the car. They agree on the right amount of power that the car can safely receive. Fast, efficient charging Home and workplace chargers send power to the car, and the car turns it into the charge that fills its battery. Rapid chargers do the work inside the unit. They drive power straight into the battery and fill your vehicle fast when you’re on the move EV Chargers An EV charger is a device that feeds power to an electric vehicle, giving its battery the charge it needs to run. Safe battery charging Electricity moves into your battery while the charger watches the heat and the flow of power to keep the charge safe and sure. Smart charging options Many chargers come with smart features that let you charge at night when power is cheaper and see how much energy you use.

Benefits Efficient- Built to work with low‐temperature heat sources, giving roughly three to four units of heat for every one unit of energy used. Eco-friendly- Reduces reliance on fossil fuels. Smart- Often includes controls to optimise heating times and energy use. Compatible- Works well with solar thermal systems too. Air Source Cylinder An Air Source Cylinder is a hot‐water tank that works with a small air source heat pump to supply hot water for the home. It’s built to run well on the lower water temperatures that heat pumps make, far lower than the heat from old boilers. Heats from the air An air source heat pump takes heat from the air outside and lifts it to a higher temperature with a strong, steady compressor. It keeps working even when the weather turns cold. Heating the water This heat moves through a coil inside the cylinder and warms the water stored there. Hot water on demand The cylinder stores hot water for your taps, showers, and baths. High-quality insulation keeps it hot for longer, so it is ready when you need it.

Benefits Quick to heat- Ideal for fast warmth. Slim and stylish- Fits neatly on walls. Easy to install- No plumbing required. Low maintenance- No moving parts or fuel. Electric Panel Heaters An electric panel heater is a slim, wall‐mounted unit built to heat a room fast and with little fuss. It’s a popular choice for homes, offices, and any space that needs quick, easy control of heat. How they work Efficient electric heating Each panel has an electric heating element inside. When you switch it on, electricity heats the element fast, giving off warmth quickly and efficiently. Even heat distribution The heater warms the air around it, and the warm air moves through the room by itself. Some models also give gentle radiant heat, warming people and objects directly for added comfort. Automatic temperature control A built‑in thermostat holds the room at the temperature you set. It turns the heater on and off as needed, saving energy with steady, simple control.

How they work Heat Generation A boiler or heat pump heats water using gas, oil, or electricity. Heat Distribution Hot water flows through pipes into radiators. The radiator warms the room by: Radiation - heat from the radiator’s surface Convection - warm air rises, pulling cooler air in Thermostatic Radiator Valves (TRVs) Thermostatic Radiator Valves are small devices fixed to radiators that let you set the temperature in each room of your home. They are a simple but effective way to improve comfort and save energy. Benefits Even heat distribution. Quiet operation. Zoned control with TRVs. Compatible with modern boilers and heat pumps. Radiators Radiators are part of your central heating system that provides warmth by circulating hot water or steam through a network of pipes and radiators.
