Fan-assisted radiators such as those produced by Jaga Heating Products have been designated as top performers in a new “Heat Emitter Guide for Domestic Heat Pumps” just published as part of the Microgeneration Certification Scheme (MCS) MIS3005 Standard.
The guide is intended to assist MCS installers, working with either ground source or air source heat pumps in a domestic space heating situation, to correctly select an emitter type and operating temperature which will result in high thermal efficiency and low running costs.
The independent guide was published by the Heat Pump Association, & sponsored by a prestigious array of non-partisan government bodies and leading trade associations. These included the Department of Energy and Climate Change, the Energy Saving Trust, the Ground Source Heat Pump Association, the Heating & Hot Water Industry Council, BEAMA and UHMA.
The guide uses colour coding of findings and a Temperature Star Rating to indicate how efficient the proposed system is likely to be. More efficient systems are given a higher number of stars up to a maximum of six stars. More stars were given when lower heat emitter temperatures are used because the heat pump is able to operate more efficiently.
In the Guide, fan-assisted radiators were found to cover the widest range of applications satisfactorily with flow temperatures all the way down to 35°C, and heat loss loads from 30 w/m² up to 120 w/m². In particular the Jaga Strada DBE fan-assisted radiator was named by the Guide as an ideal heat emitter in a system designed to the best practice recommendations found in the publication’s Guidance Table. Fan-assisted radiators such as those produced by Jaga were coloured green under the Guidance Table’s traffic-light ranking system for virtually every domestic situation, whereas the Guide urged caution in considering standard radiators for some applications as the size of a standard radiator would simply be impractical to install.
Paul Kingswell, Commercial Manager at Jaga Heating Products welcomed the findings of the Guide saying: “We are delighted to see fan-assisted radiators at last being recognised by such eminent bodies including DECC and the EST as being an suitable technology for use with heat pumps. I understand that CIBSE will now be adopting this information for their own heat pump supplement adding more impetus to the use of fan-assisted radiators in low temperature heating systems powered by renewable sources.”
In addition to the Strada DBE radiator named in the Guide, Jaga manufactures a comprehensive range of wall-mounted and free-standing, fan-assisted radiators for use in residential projects incorporating dynamic boost effect (DBE) technology. These include designer radiators such as the Knockonwood DBE, LST products such as the Play DBE which is perfect for use in nurseries and children’s bedrooms, or the Mini Freestanding DBE which is a popular choice where a powerful heat output is required in conservatories or in front of large areas of glazing.
Paul Kingswell added: “At Jaga, we are also looking forward to seeing the commercial heat emitter guide that is currently being produced by the Heat Pump Association. We are confident that our dynamic, fan-assisted trench heating products will perform equally well in that analysis. “
