Heating of buildings - Import export

Colloide designs and installs heat pump systems. The heat pump extracts the energy at the source temperature and then raises the temperature to a useable level. A heat exchanger is used to extract the heat from the circuit at this point, with the now cooled medium being returned to the source where it is reheating. Reversible heat pumps can also be used in cooling function which can be important in the summer months. The heat pump works as part of a closed loop, operating between the heat source and the building where it is to be used. Heat sources include air, water, ground and waste heat. The higher the temperature and larger the size of the source energy, the better it is for providing energy. Colloide designs its systems to maximise the return from the heat source. Our heat pumps include a control system. The control system will vary depending on the plant, but is always designed to give our customers full control, including the ability to monitor performance remotely.

District heating systems include a centralised energy centre which then distributes the heat through a network of insulated pipes to the buildings which are connected to the network. The network of pipework consists of a flow and return loop which passes each building. Colloide uses local substations in each building to control the flow of water from the district heating pipework loop through each substation and this flow is used to generate heat in the local building. The central energy centres are generally designed to have more than one energy source, which allows the plant operator to select the most cost efficient and sustainable way of providing the energy needed with the energy sources being brought on and off line to meet demand. We design and build the district heating and cooling networks to include the pumps, pipework, thermal stores, instrumentation, control systems, local substations, heat exchangers and communication through a central control system.

Colloide designs and constructs sustainable biomass heating solutions for all types of businesses, from small organisations to large commercial and industrial enterprises. We design and install the complete system including the boiler, biomass storage, pipework, buffer vessels and controls. We also offer a packaged biomass system called the ‘Heat Pod’ which is a complete heating solution within its own building, ready to deliver to site. This system includes boiler(s), pipework and storage; all within one unit. Whether furnace control, pellet conveying, buffer management, hot water preparation, weather controlled heating circuit with a weekly program for two circuits, or the connected solar heating system: all of this can be controlled via a touchscreen directly on the boiler or via the internet from any PC, smartphone or tablet. It‘s a lot, but it‘s easy to handle as the images on the touchscreen are self-explanatory.
