When is a PIC valve not a PIC valve?

Heat Interface Units (HIUs) contain valves to enable control. Some, such as our new Hiper HIU contain a Pressure Independent Control Valve or PIC valve. The term is often used a little too broadly in the industry to describe components in HIUs that strictly speaking aren’t really PIC valves; therefore the purpose of this short […]

Consumer Benefits of HIUs

If you have ever read some of the consumer utilities forums concerning Heat Interface Units (HIUs) and communal heating projects generally, you will know that a commonly raised concern is the inability to switch energy suppliers (like those of us on regular gas supply can do fairly easily thus keeping energy prices keen). When future […]

Buffer Tanks for chilled water storage and cooling

At Mibec we supply a wide range of water storage and Buffer tank products. Although usually associated with heating applications, this short article describes how buffer tanks can be used in chilled water storage and cooling applications. Chilled Water (CHW) systems used to cool a buildings indoor air and equipment and are becoming increasingly common […]

District Heating in Northern Europe – what can the UK learn?

District heating still only makes up around 2% of the UK energy market which is much lower than other parts of Europe (particularly Northern Europe) as can seen in the table below: Country % of citizens served by district heating Iceland 92% Denmark 63% Sweden 52% Finland 50% Germany 12% France 7% UK 2% Data […]

Use of lower flow and return temperatures in district heating

District heating schemes make use of underground pre-insulated pipes to connect the various buildings on the site to a centralised heat source. The pre-insulated pipes are designed to maintain the water temperature when in transit (avoiding heat losses to improve energy efficiency). When planning a district heating project the specifier will often have a choice […]

Benefits of District Heating

A district heating network has a central heat source supplying heating water and / or domestic hot water to two or more separate buildings on the site. This heat source will then be connected to the various buildings in the scheme via an underground pre-insulated pipe network designed to maintain the water temperature when in transit […]

Benefits of dual and quad core pre-insulated pipe

At Mibec we supply a wide range of pre-insulated pipe products from leading manufacturers like Rehau, Microflex or our own Mibec DHP pipe. Pre-insulated pipe is typically used to form district heating networks and are specially designed to maintain the water temperature when in transit between the central heat source and the buildings in the […]

What size of pre-insulated pipe do I need?

Pre-insulated pipe is typically used to form either district heating networks or connect a building to a remote heat source in smaller A-to-B projects. This type of product is specially designed to maintain the water temperature (for hot water and /or heating water) when in transit between the heat source and the buildings on the […]

How is pre-insulated pipe used to form district heating networks?

A district heating network has a heat source supplying heating water and / or domestic hot water to two or more separate buildings on the site. This central heat source will then be connected to the various buildings in the scheme via an underground pipe network designed to maintain the water temperature when in transit […]

What sort of building projects are most suitable for shared heating?

Any shared heating scheme is centred around the concept of a site utilising one large heat source running very efficiently, rather than each building or property having separate smaller ones running less efficiently – the idea being to reduce overall CO2emissions, increase efficiency and save on running costs. When we think about shared heating schemes […]
