Apartment innovations 4: the direct electric option

Topic: heating, eco controls, Efficiency, Domestic hot water, atBOS, Direct electric heating, Automation

Direct electric space and water heating can replace the need for ‘wet’ central heating in a well-insulated flat. Fast-response heaters automated by a control system are inexpensive to install, avoid the overheating risk inherent to wet heating, and meet or exceed the efficiency of electricity augmented by...

Psi-values: What are they and why do they matter?

Topic: UK building regulations, Building performance, Regulation, SAP

In this article we look at the impact of psi-values and why they matter. Psi-values are a measure of the heat loss of a junction between two fabric elements, eg floor and external wall. These junctions are called non-repeating thermal bridges.

Previous iterations of the UK Building Regulations have raised awareness...

Apartment innovations 3: hydrogen in the gas main

Topic: heating, Infrastructure, Natural gas, Domestic hot water, Hydrogen

The British government’s hydrogen strategy calls for a massive expansion in hydrogen production and evaluation of whether it can replace natural gas as the major energy source in the building sector. However, the available evidence suggests that the infrastructural investment would be better directed toward...

Apartment innovations 2: heat pumps powering heat networks

Topic: heating, District heating, heat network, Air-source heat pump, Net zero, Heat pump, Waste heat

Because fifth-generation heat networks use disseminated power sources, they can make use of air, ground or water-source heat pumps even if heat pumps alone cannot heat water to the required flow temperature. To be cost-effective, heat pumps are likely to need local waste heat sources.

Heat pumps take on direct electric heating in London

Topic: heating, Efficiency, Energy, Air-source heat pump, Domestic hot water, ASHP, Direct electric

Air-source heat pumps (ASHPs) are widely promoted as a source of low-cost, low-carbon space and water heating. However, a model of ASHP-powered heating in London shows that they compare unfavourably to heating derived directly from mains electricity, especially when compared to real-world data from flats using...

Apartment innovations 1: fifth generation heat networks

Topic: heating, District heating, heat network, Net zero, Domestic hot water, Low temperature heat network, Fifth generation, 5th generation, Regulation

Fifth-generation heat network technology uses disseminated energy sources and low flow temperatures, enabling utilisation of multiple waste heat sources and limiting heat energy lost from piping. It may make heat networks efficient enough for some apartment blocks although heat networks need to be regulated to...

Electric combi boilers - the pros and cons

Topic: heating, Efficiency, Gas, Bills, Electricity

Given the recent rise in gas prices and the UK government’s stated aim of making all newly built homes ‘zero-carbon ready’ by 2025, the need to move away from using gas to heat and produce hot water for domestic properties has been brought into focus.

One of the technologies that is seen as an alternative to a gas...

Heating bills are soaring: are we too dependent on gas?

Topic: heating, Energy, Gas, Renewable, Bills, Infrastructure, Natural gas, Electricity, Cost, Price rise, Price shock

This winter’s hike in international natural gas prices will lead to heating price hikes this winter. It exposes the vulnerability of Britain’s dependence on imported gas, both for heating homes and for generating electricity, and illustrates the importance of initiatives to replace gas heating systems.

Do the government’s boiler replacement grants solve the right problem?

Topic: heating, Efficiency, Energy, Grant, Gas, Air-source heat pump

Yesterday, the government announced a £450 million boiler upgrade scheme, offering £5,000 grants for households replacing gas-boilers with low-carbon heating systems. The scheme does not specify what low-carbon system should be used although it repeatedly refers to air-source heat pumps.
