Getting the balance right

01 November, 2017

Ensuring that office heating operates effectively and efficiently is not simply a case of setting thermostats. The entire HVAC system must be designed and balanced to control heating throughout a building. Greg Tracy explains how this can be achieved.

Boiler replacement, Chris Meir, Remeha

Mind the gap

01 November, 2017

Boiler replacement is widely acknowledged as a quick win to improved heating reliability and efficiency. So why do we hear of some boilers failing to deliver the projected performance and savings? It all comes down to ensuring good system design, says Chris Meir.

Stuart Turner, ErP Directive, Hamworthy Heating

Thanks to legislation such as the Building Regulations and the Energy-related Products (ErP) Directive, we have long seen a development towards highly efficient heating products. But there is more to an efficient boiler than just its theoretical efficiency figures according to its data sheet – correct setup, operation, service and maintenance are just as important, explains Stuart Turner.

Designing in performance

01 November, 2017

Engineered heating solutions can answer the challenges of installations that aren’t suitable for off-the-shelf products. They offer the flexibility required to meet the heating needs of ‘problem’ buildings, explains Danny Packham.

JS Air Curtains has introduced the Zen range, which means that fascia panels can be custom-made in many different materials; screen printed to carry logos or images; and manufactured to incorporate elements such as clocks and LED displays.


Viessmann has been named as ‘Best Buy’ boiler brand by consumer magazine Which? Viessmann was praised by Which? as the ‘most reliable’ of all brands.

space heating, boilers, Remeha

Achieving reliable heating in buildings requires a flexible, high-performance solution. With their improved ease of installation and outstanding high efficiencies, it’s no wonder that tried-and-tested condensing boilers are ticking all boxes, says James Porter of Remeha.

10 years in wall-hung boilers

02 November, 2016

Boilers and the technology associated with them seem to change very slowly, and even quite an old boiler could, until quite recently, quite easily be replaced with like for like. One of the most significant changes has been the move towards wall-hung boilers and their use in cascade configurations, as highlighted by John Bailey, Vaillant’s sales director for commercial and renewable systems, reflecting on 10 years of Vaillant being involved with commercial systems in the UK.

space heating, Rinnai, fan Convector, heater

Rinnai’s Energysaver range of fanned-convection powered-flue gas-fired space heaters are designed specifically for use in schools, community centres, libraries, conservatories and churches and other large spaces. Recent enhancements to the range include the 559FT (pictured) and the 309FT.

Despite increasingly stringent carbon-reduction targets, achieving Part L compliance with electric heating in non-domestic buildings remains viable and can deliver significant benefits. Chris Stammers of Dimplex explains how.

space heating, Micronics, flowmeters

Micronic flowmeters have been used at Heathrow Airport’s Terminal 4 to survey energy usage in the heating system. The facilities staff at the terminal have a 5-year plan running to 2019, entitled Quinquennium 6, which includes the redesign of the medium-temperature hot-water system, which previously ran at 120°C. The requirement was to run the system at a lower temperature to be more cost effective, more environmentally friend and — crucially — safer.

Sabien, EndoTherm

It is well-established that imperfections in a heat exchange surface can have a negative impact on heat transfer. Tony Willis of Sabien Technology explains how a CIBSE award-winning additive to reduce the surface tension of the heating fluid can improve performance.

LST fan convectors

02 November, 2016

The Caspian LST (low surface temperature) range of fan convectors from Smith’s EP UK fully complies with the NHS Estates Health Guidance Notes ‘safe hot water and surface temperatures’ (formerly known and DN4). Compliance has been independently verified by BSRIA.

space heating, radiators, LST, Stelrad Radiators

Radiators have a number of features that make them suited to a range of commercial applications, and recent developments enable them to provide a solution for more applications. Chris Harvey of Stelrad Radiators takes up the story.

space heating, boilers, Viessmann

Viessmann’s Vitodens 200-W boiler cascade system for commercial applications is more compact than its predecessor and offers outputs from 12 to 594 kW. It requires 30% less space than the previous cascade system and reduces installation times by up to 50%. The height required for installation is reduced from 2.2 to 1.8 m. The width required is also reduced — for example, three boilers in series require 2.3 m compared with 2.7 m previously.

As the number of urban high-rise developments continues to increase, so does the trend for electric heating. Alan Clarke of Heatrae Sadia, talks electric wet central-heating boilers and the key points to consider when it comes to product specification.

Heat interface units and billing services for the communal heating system in a development of luxury apartments and homes for first-time buyers in the Ladbroke Grove development from Taylor Wimpey Central London were supplied by Evinox Energy. The development is part of the regeneration of Grand Union Centre and also includes office accommodation and retail units. Evinox worked with P. R. Morson on the developments.

BSRIA, space heating

The industry was recently given the opportunity to provide feedback on standards and performance on heating systems in non-domestic buildings. There was some lively discussion.

space heating, renewable energy, DHW, Rinnai

Rinnai’s continuous-flow water-heating solutions can work with renewable-energy sources such as solar-thermal and air-source heat pumps. The concept is that the water heater tops up the temperature of stored water heated using renewable energy — but only when required.

space heating, Dunham-Bush, trench heating

Dunham-Bush trench-heating systems were specified for Building 3 at Advanced Manufacturing Park’s Technical Centre in Rotherham to offset heat losses and down draughts from the glazed facade. This building provides flexible offices and workshops for up to 11 tenants involved in industries as diverse as aerospace, automotive, marine, petrochemical and power generation.

The perfect warm-up routine

02 November, 2016

Schools, colleges and other educational establishments throughout the UK spend hundreds of millions of pounds a year on heating. It’s an essential outgoing, but that doesn’t mean cost savings can’t be achieved. Even the most complex of heating needs can be met without breaking the budget, according to Nick Winton of Nor-Ray-Vac.

03 March, 2016

Inta’s Hiper heat interface unit (HIU) has separate plate heat exchangers for heating and DHW. Features include a factory-set non-electric temperature-control valve to prevent the risk of scalding if the power supply fails. Dual-speed PID control intelligently controls the heat into the plate heat exchange by the electronic modulation of a PICV (pressure-independent control valve).

Strebel, burner, space heating

Marriott International selected Strebel to provide more efficient heating and hot water for its Forest of Arden Marriott Hotel & Country Club in the West Midlands. The new heating solution comprises three boilers with 10 sections and outputs of 700 kW with Baltur gas burners supplied by EOGB.
