Technology Solar Thermal (Hot Water)
General Specifications/Information
Hot Water Cylinder Specs: 320 Litres Capacity, 99oC Max Temp & Max 10 Bars
Cost of Technology £5,880
Estimated Annual Savings tCO2
£85 + £242 (RHI) - Calculated on 2011 prices. 0.5
Estimated Payback Period 18 years
Typical Performance The hot water from the storage vessel is used to supply the toilets on the 3rd floor of the Brundtland Building
The solar controller is the brains of the system and monitors the tem-perature, performance and controls the main
pump
The immersion heat en-sures that the tempera-ture of the water in the
tank is hot enough
The single coil storage vessel is used to store
the hot water ready for domestic use
The hot water from the storage vessel is then used to supply the toi-lets on the 3rd floor of the Bruntland Building
Roof Installation Classroom Installation
The solar collectors mounted on the roof convert the light into heat. The heat is created by the absorption of the suns rays through a dark coated
metal plate called the absorber. Heat is transferred from the collectors into a glycol solution within the
pipework
Solar Thermal Operation The aim of the solar thermal system is to pre-heat the cold water supplying the hot water storage vessel. The main heat source for the vessel is an electric immersion heater. The immersion heater can raise the temperature of the water from 10°C to 65°C if required. The solar thermal coil pre-heats the water so that depending on the time of year the load on the immersion heater is reduced. By reducing the electrical load on the immersion heater it reduces the amount of fossil fuels used to generate electricity.
A pasteurisation pump mixes the water within the vessel making sure there is an even
temperature throughout
The heated glycol solution is pumped through the solar thermal coil, pre-
heating the cold water within the storage
The main pump circulates the glycol solution. Glycol is a thick liquid which is used for its heat
transfer and anti-freeze properties
