November 2021 Meeting — Air Source Heat Pumps

Living with an Air Source Heat Pump (ASHP)

Update: We had a second speaker Jesse Scharf as well as Jonathan Waxman as originally advertised. Here are their slides:


Our November meeting is on Wednesday 24th November 2021 from 7pm to 8pm online.

Please book on Eventbrite at https://www.eventbrite.com/e/living-with-an-air-source-heat-pump-ashp-tickets-211638726127. A Zoom link will be sent to all registered participants.

Air Source Heat Pumps (AHSP) are a low carbon technology to heat homes – what is it like living with one?

There has been much in the press of late around the end of gas heating and a shift to new home heating solutions from heat networks to heat pumps. The Prime Minster has stated that there will be ban on all new gas boilers in new build properties from 2025 and a ban on gas boilers being fitted into all homes from 2035.

The Government has set a target for annual installations of heat pumps in 600,000 homes by 2028 – a 20 fold increase over the current rate of installs. Many of these are planned to be added in new build homes – but at least a third are hoped to be retrofitted into existing homes. A new Boiler Upgrade Scheme is to be introduced in April 2022 to support the deployment of low-carbon heat in existing buildings. This will provide households with £5,000 grants when they switch to an air source heat pump (ASHP) or £6,000 when they switch to a ground source one.

Jesse Scharf and Barnet resident Jonathan Waxman have both recently had ASHPs installed in their homes and will be providing some insights on the process leading up to the choice of a heat pump, the installation process and kit, costs, and the differences in heat your home with a heat pump as compared to a conventional gas boiler.

Reducing carbon emissions from Barnet’s homes

by Syed Ahmed

A great blog by housing energy efficiency specialists Parity Projects on the workforce required to see homes on a zero carbon pathway – and the retrofit tasks and skills required to upgrade homes. As a reminder of the challenge just in Barnet – never mind the UK – there are 160,000 homes in the borough. The latest data shows that through the Mayor’s energy efficiency scheme have supported the retrofit of exactly 200 homes in the borough since 2016 (see data here). The Energy Company Obligation (ECO) programme is the Government’s main household energy efficiency programme. The latest data published by the Department of Business Energy and Industry (BEIS) shows that just over 5,000 homes received an energy efficiency improvement since this new phase of the scheme began operation in 2015. (See BEIS statistics for March 2020 here – tab 4.4 of the spreadsheet there).

So – over the past five years or so, being generous, some 5,500 homes in Barnet have had some form of energy efficiency improvements installed through a targeted programme. In addition – approximately 1.6m boilers are replaced every year across the UK. Barnet’s likely share of this would be about 10,000 or so per year – 50,000 over the past five years – which would all have improved the energy efficiency of homes.

Whilst this level of activity is to be welcomed, none of the work currently being undertaken in existing homes achieves anything near the zero carbon standard needed to fully address the climate emergency. Much deeper retrofits are required, and the scale of action needs to be significantly increased if we are to reduce emissions from the domestic sector across Barnet and all other parts of the UK.

Prioritising energy efficiency in Barnet’s homes will boost opportunities for local building services companies, insulation firms, plumbers and other associated trades. These are exactly the SMEs currently being hammered during the lockdown. Boosting energy efficiency will be good for Barnet’s homes, for tackling fuel poverty, for resident’s health and supporting local businesses and employment.
