Section 4: Electric heating

This section provides guidance on the specification of fixed electric heating systems for dwellings to meet relevant energy efficiency requirements in the Building Regulations.

4.1 Scope of guidance

The guidance given in this section covers the following types of fixed electric heating systems:

• electric boilers serving central heating systems
• electric warm air systems
• electric panel heaters
• electric storage systems including integrated storage/direct systems.

Portable, plug-in appliances are not covered by the Building Regulations or by this guide.

4.2 Electric boilers serving central heating systems

Electric boilers serving wet central heating provided with new systems or as replacement components in existing systems should meet the minimum standards for:

a. system circulation, system preparation and commissioning in Table 16

b. boiler interlock, zoning, and time control and temperature control of heating and hot water circuits in Table 17

c. hot water storage systems in Table 18

d. pipework insulation in Table 19.

****Table 16 Recommended minimum standards for system circulation, preparation and commissioning for electric wet central heating systems****

 ****Table 17 Recommended minimum controls for electric wet central heating systems****

****Table 18 Recommended minimum standards for hot water storage in electric wet central heating systems****

****Table 19 Recommended minimum standards for insulation of pipework in central heating systems with electric boilers****

4.3 Electric heating systems (other than electric boilers serving central heating)

This section provides guidance on the following types of fixed electric heating systems:

• electric warm air systems
• electric panel heaters
• electric storage systems including integrated storage/direct systems. Portable, plug-in appliances are not covered by this guide.

Fixed electric heating systems (other than with electric boilers) should meet the minimum standards for time and temperature control in Table 20.

****Table 20 Recommended minimum controls for primary and secondary electric heating systems (other than with electric  boilers)****
