Based in Cambridge and working throughout the East of England, we offer the specialist advice you need on all of the different types of renewable energy system currently available. Whether you are interested in solar panels, a super-efficient ground or air source heating system to heat your property, a modern energy efficient boiler installation or a low temperature under floor heating system, Green Solar World are the people to rely on for both great advice and a high quality installation.
16kW Samsung Air to Water Heat Pump, Cylinder, fully supplied, installed and certified by an MCS and NAPIT accredited installer. Air Source Heat Pumps, extract latent heat from the outside air, and intensify it, to heat your home and water all year round. They can produce 4kW of heat from just 1kW of electricity, making them 4 times more efficient than a standard electric heater. They are ideal for properties with Solar PV as the electricity generated from your panels can offset the cost of running the pump!
off grid inexpensive cabin solar setup.we are running our freezer off solar.Not sure if it will work full time, but it works now.
