SAV Installs World’s First 2-Way OMS LPWAN Burst Mode Heat Metering Network
SAV Systems, in partnership with Metropolitan and Kamstrup, deployed a wireless heat network on the novel OMS LPWAN Burst Mode technology, with 2-way valve control in low-density UK housing. The solution meets UK regulatory (HNTAS) demands for 30-minute data, offers up to 100% service level agreement (SLA) on data collection, max 15-minute valve on/off latency, […]
Temperature as a Design Input, not a Constraint
Cast your mind back ten years. Gas boilers and combined heat and power (CHP) were the stars of any plant room: low CAPEX, low OPEX, easy to install, simple to run, and comfortable operating at high delta Ts between flow and return. The market had moved from a temperature set of 82/71 down to 70/40 […]
Heat Pump Noise: A Design Problem
Heat pump noise is appearing more frequently as a project constraint. Planning conditions are becoming more specific, and noise assessments are being requested earlier in the design process. This article outlines why some common responses to noise constraints make things worse, and covers top-level approaches to managing noise without compromising performance. Noise constraints take several […]
The Cost of Poor Decarbonisation Sequencing
Sign up for CPD This article is the third in a series on peak demand in electrified heating systems. The previous piece – The Design Sequence: What Happens Before Plant is Sized – described the decisions that determine peak heat demand before a heat pump is selected. This one examines what the process produces when […]
Developing Resilience in our Energy Systems
Recent global events have thrown into stark relief just how exposed the UK remains to energy markets it cannot control. Russia’s invasion of Ukraine sent gas prices surging across Europe. Now, with US and Israeli military action against Iran, oil prices spiked by over 40% in days – briefly hitting their highest level in nearly […]
The Design Sequence: What Happens Before Plant is Sized
Sign Up for CPD This article is the second in a series on peak demand in electrified heating systems. The first – Peak Demand and the Shift to Storage-Led Design – made the case for storage-led energy centre design. This one goes further back: to the decisions that determine how much peak demand a storage […]
Peak Demand and the Shift to Storage-Led Design
Sign Up for CPD This article forms part of a series. The previous article is Why the industry is moving towards second generation heat pumps. The System Constraint Peak energy demand is shaping the economics of heat electrification in the UK. As buildings transition away from gas to fully electric plantrooms, synchronised heating patterns risk […]
Why the industry is moving towards second generation heat pumps
Download Datasheet Heat pump deployment in the UK is accelerating rapidly, but much of the equipment in use today is still shaped by cooling-led design assumptions inherited from first generation heat pumps. These first generation heat pumps typically operate at low temperature differences (∆T), rely on constant flow, and require heating systems to adapt around […]
