HEVAC position paper on the interpretation of the Pressure Equipment (Safety) Regulations (PE(S)R) - April 2022

During 2021 there was several discussions within FETA groups regarding PE(S)R. There are some differences in how these regulations are viewed by various parts of the industry. There are a lot of different guidance notes available (see references), not all of which are very helpful to someone trying to understand how the regulations apply to them.

It is not appropriate for FETA to offer interpretation on these regulations, as we do not have the technical knowledge to do this. However, we are keen to try and get a consensus over how these regulations are interpreted and implemented by our members and this is included in this position paper.

Air Source Split and Multi-Split Heat Pumps (incl.VRF) spreadsheet

The following information was provided by the Carbon Trust on the de-listing of AIR SOURCE SPLIT AND MULTI-SPLIT HEAT PUMPS (INCL.VRF) in October 2014

Below is a link to a blank copy of the VRF master spreadsheet, should this be required by manufacturers who haven’t previously listed their Air Source Split and Multi-Split Heat Pumps (incl. VRF) in this way, and who want a calculation checker against the current ETL calculations (which haven’t changed since August 2013). For manufacturers who have listed these previously, the Carbon Trust has sent them a copy of their last spreadsheet in a format so that they can update their outdoor and indoor units.

Air Source Split and Multi-Split Heat Pumps

The main thing to highlight to manufacturers is that the worksheet is a tool for confirming whether the product combination of outdoor and indoor units would be compliant (subject to the products meeting the ETL criteria).

Where customers wish to claim an Enhanced Capital Allowance against their purchase of Air Source Split and Multi-Split Heat Pumps incl. VRF (ASSMSHPs), they need to have evidence that the product was compliant with the Energy Technology List criteria at the time. It is normal for manufacturers to make a statement to that effect in an ‘unlisted’ category such as the ASSMSHPs where the manufacturer can show that it was compliant, which customers can then use with their claim. The compliance check of the combination of outdoor and indoor units may support that statement.

Carbon Trust understands that HEVAC/FETA won’t be able to make any changes to the spreadsheet if the calculations need to be updated as a result of future criteria changes. If there is a change needed, the Carbon Trust will either ask for the spreadsheet to be removed or adjust the calculations and send FETA the updated version.
