Heat Interface Units
What is a Heat Interface Unit (HIU)?
Heat interface units (HIU’s) are typically installed in large multi apartment complexes with numerous dwellings, acting as a ‘bridge’ between a central boiler and the individual heating and hot water systems. Traditionally each dwelling would have it’s own independent boiler whereas an HIU system has one central (district) boiler that provides the heating and hot water energy to the whole complex.
The Benefits of District Heating?
1. Renewable Energy can be utilised easily
One of the primary and most important considerations in modern construction is energy conservation, through the deployment of energy-efficient plant. Heating Interface Units (HIU’s) produce hot water by way of a centralised district heating plant (generally powered by renewable energy methods) which is transferred via integral heat exchangers, to provide on-demand heating and hot water. Heat Interface Units deliver eco-friendly temperature control to the occupants of the residence.
Heat interface units allow building services engineers the option to design multi-dwelling complexes with district heating systems, utilising renewable energy sources like Solar, CHP and heat pumps. This can be done very easily as each individual dwelling doesn't need its own independent system. One ‘mother’ renewable system can be fitted to power the whole building then redirected to the separate areas as required. Domestic hot water can be provided with ease, using a plate heat exchanger, which enables excellent levels of comfort for the occupants.
2. Increased living standards
Domestic hot water can be provided by heating interface units (HIU) on-demand, without the necessity of individual cylinder storage, and at an increased flow rate compared to a typical domestic combination boiler system. Heat interface units are available at differing capacity levels to suit all requirements.
3. Reduction in investment and maintenance
Rather than supplying each residence with gas, and installing numerous domestic boilers, heat interface units require only a hot water riser connected to each apartment and a central boiler plant. This alone leads to a significant saving.
Heat interface maintenance is kept to a minimum as units only need a hot water riser connecting to each individual dwelling within a building along with a single central boiler plant. This means a significant saving can be made with no need for individual gas supplies and boilers and a building wide network to install.
Heat Interface Units are far easier to install than traditional boilers and no gas training qualifications are required for installers; there is no gas connection and no flue pipe, so ventilation routes are not required. Ongoing maintenance is greatly reduced and gas-qualified engineers are not required for the maintenance of heat interface units themselves either. This also means less disruption for building occupants.
4. How much does a heat interface unit cost?
