When it comes to return on investment, size matters In buildings where there is a large heating/cooling demand over extended periods, the benefits of combined heat and power (CHP) are hard to beat.

Finding a fan base in a few new sectors Not just for large commercial use, smaller CHP units are attracting new sectors of the market.

Alex Parkinson of Bosch Commerial Heating evaluates the pros and cons of multiple module CHP systems vs single module arrangements

Renewable and low carbon technologies should be hailed as the saviour of commercial heating, helping users to reduce their carbon emissions and cut energy costs.

It’s not often you get to see something completey different, but when you go behind the scenes of the conservation site of the 16th Century Mary Rose in Portsmouth’s historic dockyard that’s exactly what you get.

The Building Regulations require ductwork leakage testing, with implications for designers, installers, and maintenance contractors. Peter Rogers chairman of the B&ES Ductwork Group Technical explains

Stored hot water systems suffer badly from the problem of scale build up – even when water treatment measures are set in place which could put a burden on water heaters. Scott Humphries argues in favour of zinc-based calcium inhibitors.

What is the right way to cost effectively cool a data centre? Is it about increasing the input temperature? Maybe aisle containment is the answer? What about free air cooling?

Ground source suits the residential sector Chris Davis explains the benefits of district ground source heat pump systems for the residential sector

Hybrid heat pumps are an attractive option for combi boiler replacement, particularly as they are eligible for domestic Renewable Heat Incentive payments, argues Nancy Jonsson.

The new UK Annex to BS EN 15287-1, the European installation standard for flues and chimneys, has introduced the most radical changes to the guidance on flue installations for biomass applications, for many years.

As we approach what is predicted to be another scorching summer commercial property owners, facility managers and office managers will be under extreme pressure to ensure that their air conditioning plants can cope with higher, prolonged temperatures to maintain a cool comfortable working environment. Carl Webb identifies a solution for hire.

Everyone knows that the boiler systems in combined heat and power (CHP) plants of any commercial building need maintenance and servicing at regular intervals, but John Hamnett says the same applies to flues and chimneys.

When independent Rolls-Royce Motor Cars fanchise P&A Wood built a new showroom the utmost care and consideration had to go into specifying a heating system.

Mechanical ventilation and heat recovery units, more commonly known as MVHR, are increasingly common in the UK, but results can be variable.

Most manufacturers of heating systems are now looking to systems that deliver whole life costs as a way of making real energy savings.

Renewable heating technologies provide clean energy, reducing carbon emissions and improving a building’s performance, claim manufacturers.

As we approach what is predicted to be another scorching summer commercial property owners, facility managers and office managers will be under extreme pressure to ensure that their air conditioning plants can cope with higher, prolonged temperatures to maintain a cool, comfortable working environment.

Demand control is a key concept for optimising the performance of building services plant but it’s essential not to lose sight of the fundamental engineering principles.

Martin Wilkinson explains why correct pressurisation is vital to heating system efficiency.

When it comes to heating commercial spaces, fan convectors are often overlooked regardless of whether or not they are the optimum heating solution. But it’s worth taking a look at the benefits says David Higham

Commercial buildings in the UK are crying out for heating engineers to help reduce their running costs. Bryan Gates tells Heating and Ventilating Review about the opportunities this is providing.
