Regulation 3

SCHEDULE 2 Product requirements

PART 1 Introduction

1.  This Schedule sets out in relation to a listed product the requirements that must be met by that product.

PART 2 Boilers and appliances

1.  A boiler or an appliance must comply with the useful efficiency requirements—

(a) at rated output (that is operating at rated output Pn expressed in kW, at an average boiler-water temperature of 70 degrees C); and

(b) at part load (that is operating at 30 per cent part load, at an average boiler-water temperature which varies according to the type of boiler),

set out in the table in paragraph 2.

2.  The table referred to in paragraph 1—

Useful efficiency requirements

(1)

Including a condensing boiler using liquid fuels

(2)

Temperature of boiler water supply

Type of Boiler Range of power output Efficiency at rated output Efficiency at part load
KW Average boiler-water temperature expressed in degrees C Efficiency requirement expressed in percent Average boiler-water temperature expressed in degrees C Efficiency requirement expressed in per cent
Standard 4 to 400 70 Greater than or equal to 84+2 log Pn Greater than or equal to 50 Greater than or equal to 80 + 3 log Pn
Low temperature(1) 4 to 400 70 Greater than or equal to 87.5+1.5 log Pn 40 Greater than or equal to 87.5 + 1.5 log Pn
Gas condensing 4 to 400 70 Greater than or equal to 91 + 1 log Pn 30(2) Greater than or equal to 97 + 1 log Pn

3.  A boiler or an appliance with a dual function of—

(a) heating premises; and

(b) providing sanitary hot water,

must comply with paragraph 1 to the extent of the heating function only.

4.  A boiler which is—

(a) a back-boiler; or

(b) a boiler designed to be installed in the living space,

must be treated as a standard boiler but its efficiency at rated output and part load may be 4 per cent less than shown in the table in paragraph 2.

PART 3 Refrigerator appliances

1.  If a refrigerator appliance is within categories 1 to 9 as described in table 1 in paragraph 2, the maximum allowable electricity consumption (Emax) of that appliance, expressed in kWh per 24 hours, is set out in column 3 of that table.

2.  The table referred to in paragraph 1—

Table 1

Requirements for maximum allowable electricity consumption – appliances in categories 1 to 9

Category Description Emax (kWh/.24h)
1 Refrigerator without low temperature compartment (being any compartment with a temperature at or below -6 degrees C) (0.207 x Vadj + 218) / 365
2 Refrigerator/chiller with compartment at 5 degrees C and/or 12 degrees C (0.207 x Vadj + 218) / 365
3 Refrigerator with no-star low temperature compartment (0.207 x Vadj + 218) / 365
4 Refrigerator with low temperature compartment (*) (0.557 x Vadj + 166) / 365
5 Refrigerator with low temperature compartment (**) (0.402 x Vadj + 206) / 365
6 Refrigerator with low temperature compartment (***) (0.573 x Vadj + 206) / 365
7 Refrigerator/freezer, with freezer compartment (****) (0.697 x Vadj + 272) / 365
8 Food freezer, upright (0.434 x Vadj + 262) / 365
9 Food freezer, chest (0.480 x Vadj + 195) / 365

3.  If a refrigerator appliance—

(a) has more than 2 doors; or

(b) is not described in table 1,

the maximum allowable electricity consumption (Emax) of that appliance as described in columns 1 and 2 of table 2 in paragraph 4, expressed in kWh per 24 hours, is set out in column 3 of that table.

4.  Table 2 referred to in paragraph 3—

Table 2

Requirements for maximum allowable electricity consumption – other appliances

Temperature of the coldest compartment Category Emax (kWh/24 hours)
> - 6 degrees C 1/2/3 (0.207 x Vadj + 218) / 365
- 6 degrees C(*) 4 (0.557 x Vadj + 166) / 365
- 12 degrees C(**) 5 (0.402 x Vadj + 219) / 365
- 18 degrees C (***) 6 (0.573 x Vadj + 206) / 365
- 18 degrees C(****) 7 (0.697 x Vadj + 272) / 365

5.  The categories 1 to 7 referred to in column 2 of table 2 are the same categories of refrigerator appliance numbered 1 to 7 referred to in column 1 of table 1.

6.  The following have effect in respect of tables 1 and 2—

Vadj
Wc

7.  For the purposes of paragraph 6—

Vadj is the value of the adjusted volume (in litres);

Vc is the net volume (in litres) of a given type of compartment in the appliance;

Tc is the design temperature in each compartment (in degrees C);

Fc is a factor which equals—

(a)

1.2 for no-frost compartments; or

(b)

1 for other compartments;

Cc is—

(a)

1 for refrigeration appliances belonging to the normal (N) and subnormal (SN) climate classes;

(b)

Xc for refrigeration appliances belonging to the sub-tropical (ST) climate class; or

(c)

Yc for refrigeration appliances belonging to the tropical (T) climate class;

Xc and Yc are weighting co-efficients defined in paragraph 8.

8.  The following table defines the co-efficients Xc and Yc referred to in paragraph 7—

Table 3

Table of weighting co-efficients Xc and Yc, according to the temperature of the compartment

Xc Yc
Cellar compartment 1.25 1.35
Fresh food compartment 1.20 1.30
0 degrees C compartment 1.15 1.25
