EuP ready pump – managing the transition

Nu-Heat now offers a range of energy-efficient pump options that meet the requirements of the Energy Using Products Directive (EuP).

Agreed in 2005, the objective of the EuP is to reduce carbon emissions by reducing the amount of energy used, including in domestic heating and hot water.

Nu-Heat now supplies one of the most advanced energy efficient domestic circulators of its kind on the market today; essentially, a direct replacement for previous models. The reduction in power consumption has been achieved by using the latest permanent magnet motor technology.

It hasn’t been the easiest task for Nu-Heat to adapt our existing products to accommodate the EuP-ready pumps and manage the stock transition, but we managed to do this in good time, although it was further complicated by the additional product innovation that is still going on subsequent to the legislation change.

The change has, however, been positive in terms of system design. Nu-Heat now uses a smaller range of pumps but, without exception, the variable-speed equivalent has a greater capacity (both in terms of head and flow capability) than the old fixed-speed counterpart. Being able to do more whilst using less power has to be advantageous.

There are pumps in just about everything that we sell, and different products require the pumps to be set up differently – for example an underfloor heating pump will be set in constant-pressure mode, whereas the shunt pump on our thermal store still needs to run in fixed-speed mode. Heat pumps, on the other hand, tend to use the pump at maximum capacity (the highest fixed-speed mode) in order to get the closest temperature differential. The range of pumps that we use has the capability to fulfill those needs, and our literature offers installers guidance on what mode is suitable.

Within the business variable speed (EuP-ready pumps) seem to have been with us forever, although Nu-Heat’s Technical Support department now has to explain that service replacement pumps will not be the same as the original item. Overall the new pumps represent a better product for the end user.

Permitted development measures

A raft of measures granting new permitted development rights in England will come into force on 30th May.

The measures include increasing the size of single-storey rear extensions that can be built under permitted development for a period of three years between 30 May 2013 and 30 May 2016. These larger extensions will be subject to a neighbour consultation scheme.

An extension or addition to a house is considered to be permitted development, not requiring an application for planning permission, subject to the following limits and conditions: No more than half the area of land around the “original house” (as it was first built or as it stood on 1st July 1948) would be covered by additions or other buildings.

  • No extension forward of the principal elevation or side elevation fronting a highway.
  • No extension to be higher than the highest part of the roof.
  • Single-storey rear extension must not extend beyond the rear wall of the original house by more than three metres if an attached house or by four metres if a detached house.
  • Maximum height of a single-storey rear extension of four metres.
  • Extensions of more than one storey must not extend beyond the rear wall of the original house* by more than three metres.
  • Maximum eaves height of an extension within two metres of the boundary of three metres.
  • Maximum eaves and ridge height of extension no higher than existing house.
  • Side extensions to be single storey with maximum height of four metres and width no more than half that of the original house.
  • Two-storey extensions no closer than seven metres to rear boundary.
  • Roof pitch of extensions higher than one storey to match existing house.
  • Materials to be similar in appearance to the existing house.
  • No verandas, balconies or raised platforms.
  • Upper-floor, side-facing windows to be obscure-glazed; any opening to be 1.7m above the floor.
  • On designated land* no permitted development for rear extensions of more than one storey.
  • On designated land no cladding of the exterior.
  • On designated land no side extensions.

Please note: the permitted development allowances described here apply to houses not flats, maisonettes or other buildings.

* Designated land includes national parks and the Broads, Areas of Outstanding Natural Beauty, conservation areas and World Heritage Sites.

You are strongly advised to read a technical guidance document produced by the Government to help understand how permitted development rules might apply to your circumstances.

Nu-Heat offers a range of energy-efficient pump options that meet the requirements of the Energy Using Products Directive (EuP).

 

 

 

Agreed in 2005, the objective of the EuP is to reduce carbon emissions by reducing the amount of energy used, including in domestic heating and hot water.

Nu-Heat now supplies the Grundfos UPS2, one of the most advanced energy efficient domestic circulators of its kind on the market today; essentially, a direct replacement for previous models. The reduction in power consumption has been achieved by using the latest permanent magnet motor technology.

All underfloor heating system pumps, EnergyMaster thermal store shunt pumps, and heat pump charge pumps supplied by Nu-Heat meet the new standard. Applications that fall outside of the scope of the directive include solar thermal system pumps, and hot water loop pumps.

Using pressure controlled operation power consumption can be reduced to as low as 5 watts. The new models are simple to install as new or replacement pumps, and are 130mm between ports.

From January 2013 only energy-efficient pumps will be supplied as part of Nu-Heat systems.
