Overview of market data for base cases

An overview of market data collected in previous tasks and used for establishing the environmental and economic assessment in these tasks is shown in Table 37. The base cases for variable flow applications are sub-divided in two sub-categories: with and without VSDs. This is because no information was provided on the share of VSDs used in constant

flow applications and it was therefore assumed by the study team that the share of VSD use for each pump category relates only to variable flow applications. Furthermore, preliminary information from industry about the application of the EPA methodology on the distribution of EEI levels for end suction clean water pumps in the EU market²⁸⁶, showed that EEIc is practically independent of whether a VSD is included in the pump unit. For this reason, it makes no sense to aim for using more VSDs in constant flow applications. On the other hand, pump units in variable flow clearly benefit from using variable speed controllers, showing EEI reductions up to 50%. The share of pumps using VSDs in variable flow applications in 2014 has been provided by Europump. The use of VSDs increases efficiency of the pumps and the motors when looking at the EPA, so this indicator shows whether there is an opportunity for improvement. This is further evaluated in chapter 12 (Task 7).

An interest rate of 4% p.a. has been used for all base cases as stated in chapter 6, section 6.4. Industry electricity prices were applied for all pump categories except swimming pool pumps which are used at households. Despite that many of the clean water pumps are also used in residential buildings, it is not known what percentage of base cases is used for industrial or residential purpose in the EU. Furthermore, it is likely that they are charged electricity prices for the service sector when used by building management services organisations and/or building management boards, since for apartment buildings it is usually them purchasing pumps and paying for their operation. It has therefore been assumed that all pumps that are B2B are charged industry electricity prices and those that are B2C are charged household electricity prices (assuming household prices and prices for the service sector are close to each other).

287 Pumps used for variable flow applications can be used with or without VSD. In this table these are referred as: Pumps used with only motor (m) and pumps used with motor and vsd (vsd). The percentages are calculated based on 2014 data provided by industry.

288 Ibid.

289 Prices of constant and variable applications without VSD (m) are the same, as in both cases the price includes the pump and the correspondant IE3 motor in terms of size. Prices of variable applications with VSD (vsd) are different, considering the price of the pump, an IE2 motor and an IE1 VSD, which follows requirements in the draft Motor Regulation.

290 The average purchase prices have been weighted according to the share of VSD in variable flow applications (Use of VSDs column). For swimming pool pumps (base case#24), this was done according to the share of VSD in constant flow applications.

291 In the case of swimming pools, the VSDs are used for constant applications according to EUSA Working Group. According to them, there are no variable applications within their members.

An overview of the energy data on average user load of the pumps in the base cases is shown in Table 38. These data were used for establishing the environmental and economic assessment in this task. The use of water and other consumables are considered negligible and are therefore not shown.

An overview of the materials used for the base cases is shown in Table 39. These data were used for establishing the environmental and economic assessment in this task, and it includes the materials for the motors (for constant and variable applications) and for the VSDs (for variable applications).
