New Planning Rules For Air Source Heat Pumps

Published by Kate Anderson on November 29th, 2011

From 1 December 2011, new rules will come in to force which will see changes made to planning permission requirements if you’re planning to install an air source heat pump.

Unlike ground source heat pumps, the installation of air source heat pumps has usually been subject to planning permission.

However from next month new rules will come in to play which will mean planning permission will no longer be an issue.

Air source heat pumps will now join the ranks of the likes of solar PV, solar thermal and biomass boilers, and from December will be classed as a permitted development in England.

However, there are a few stipulations and the following criteria must be met:

  • That there is no wind turbine at the property.
  • It meets additional criteria if you live in a listed building, in a conservation area or a World Heritage Site.
  • The external unit is less than 0.6 m3 in size.
  • The unit is more than one metre from the edge of the householder’s property.
  • It is not on a pitched roof or near the edge of a flat roof.

New Heat Pump Installer Standard Good News For the Industry

Published by Kate Anderson on November 15th, 2011

Dimplex Renewables has welcomed the introduction of the new installer standard for heat pumps, saying it will be good news for the renewable heating industry.

Launched in September, the heat pump industry has worked with the Department of Energy and Climate Change (DECC) to set the new standards in place, which are designed to not only give customers better protection, but should ultimately increase the quality of heat pump installations across the board.

Perhaps one of the most common errors is the under-sizing of systems, which leads to decreased efficiency. But with the introduction of the new Microgeneration Installation Standard (MIS) 3005, new guidance has been set down to help achieve the correct sizing of heat pumps.

The right choice of heat emitters and achieving adequate heat yield from ground collectors is equally important, and the new measures should address those issues.

“The new standard is a great piece of work that will help make working with heat pumps more accessible to more installers – and that has to be good news for the industry,” said Chris Davis, business development director at Dimplex.

The new installer standards will become mandatory next month.
