Heating, ventilating, and air conditioning

Optimum start control

Optimum start controls vary the times that heating systems come on, depending on the weather, occupancy, and the current heat in the building. Using optimum start instead of fixed time control can save up to 10 % in energy costs. An optimum start controller costs between € 90 (£ 80) and € 340 (£ 300...

Heating decentralisation

Large, centralised, hot-water systems can often be inefficient. At times when demand for hot water decreases, a large system can waste energy and money. Equally, with decentralised systems it is likely that heat is being lost from long pipe runs. Installing individual heaters closer to where the hot...

High-efficiency or condensing boilers

High-efficiency or condensing boilers reduce utility bills and increase energy efficiency compared to ageing boiler units. They are also smaller and lighter than traditional boilers. Condensing boilers can be controlled via a thermostat and achieve savings between 10 % and 30 %. Where a single 200...

Double-glazed window for better insulation of buildings

Is double-glazing for you? Absolutely Having double-glazed windows installed is one of the best-known and effective ways to reduce energy bills in countries with colder winters. This technology can help to reduce heat loss and limit condensation, which also cuts heating costs, and they provide...

Integration of biomass energy in the company heat generation

Biomass as a source of renewable energy is used for a variety of applications including combined heat and power (CHP) or biofuels production. Many companies have already switched from fossil fuels to biomass, but there is more potential for growth. Among conditions to introducing biomass for heat...

Geothermal energy for heat generation

Renewable resources for heat generation are cheaper, more secure and better for the environment. The costs associated with the technology depend on the size and type of the installation. Harvesting geothermal energy for heating needs means increased autonomy (geothermal is effectively inexhaustible)...

Integration of solar energy in the company heat generation

Most industry-grade process heating systems are based on steam or hot water from boilers that today mainly burn fossil fuels like oil, gas and coal, or electricity generated by different sources. Solar process heating systems can supply up to 20-30 % of the heating demands of an average plant. This...

Use of waste heat from machines at Spiess Blechtechnik GmbH

Recycling waste energy just made sense… A metalwork plant built its own heat capping and recycling solution A simple, clever system to channel waste heat in- or outside the plant depending on the season and temperature outside Initial investment could be recouped within a year Spiess Blechtechnik is...

Heat recovery from production processes

Even in workplaces which have already introduced energy saving measures, there is still one untapped source… waste heat. Industrial or thermal processes produce heat that is all-too-often released into the atmosphere, adding to greenhouse gases. That heat can be recovered and used in various ways...

Integrate renewable energies in the company heat generation

Using renewable resources for heat generation is good for your organisation’s balance sheet and for the environment. Tapping into renewable sources to heat your buildings means a lifetime of lower energy costs and typically a fairly fast return on the initial investment. It also means an independent...
