Panasonic has unveiled the next generation of its gas-driven VRF heat pump, aimed at providing a comprehensive heating, cooling and hot water solution for large-scale commercial projects.
The company says use of a gas-driven engine reduces the consumption of electricity to just 9% of an equivalent-sized electricity-powered VRF solution, making it ideal for projects where there are restrictions to the power supply, enabling the building’s power supply to be used for other critical infrastructure such IT servers, commercial refrigeration and other building services. The GHP runs on either natural gas or LPG and a single-phase power supply, which reduces the capital cost required to upgrade power substations to run heating and cooling systems.
Peter Fardell runs a small, informal consultancy based in St Albans that seeks to keep trades involved in the plumbing and heating sector appraised of new developments. He recently experienced first-hand the benefits of LOCTITE® 577 pipe thread sealant from Henkel, after collecting a free sample at a trade exhibition.
Mr Fardell tested the product on “difficult and very loose” radiator tails after “masses of PTFE tape” failed to work; one simple application of LOCTITE® 577 produced a totally leak-tight join in seconds.
Dimplex has launched the EDL200 and EDL270 hot water heat pump, a lower carbon alternative to electric immersion heaters that makes it easier to capitalise on the benefits of electric heating for smaller properties that have to pass Building Regulations.
The hot water heat pump uses an integrated high-performance compressor to extract energy for hot water production from the external air using insulated duct work.
