Storage heaters and panel heaters are two types of electric heating systems commonly used in homes without gas central heating. They’re often installed as part of a PAS 2035-compliant retrofit to provide efficient, low-maintenance heating in properties where gas isn’t available or practical.
Storage heaters work by charging up using cheaper off-peak electricity (like Economy 7) overnight, then slowly releasing that stored heat during the day.
Panel heaters (also called electric radiators or convector heaters) provide on-demand heat and are often used in bedrooms, bathrooms, or rooms where occasional heating is needed.
Both types can be upgraded to smart, zoned heating systems that respond to occupancy and temperature settings— improving comfort and efficiency when installed correctly.
As part of a PAS 2035 retrofit, electric heating installation typically includes:
Installations follow a fabric-first approach, meaning insulation and ventilation upgrades are carried out first to reduce the building’s heat demand before heating is added.
Electric heating systems must follow PAS 2035 guidelines, including:
⚠️ Under ECO4, electric heating is only installed when:
Perfect for homes without a gas supply, especially flats or rural homes.
No pipework, radiators, or boilers — most systems install in a day.
Storage heaters can use Economy 7 or smart tariffs to reduce costs.
Each room can have its own control, often via app or Wi-Fi thermostats.
No flues, filters, or moving parts — fewer servicing requirements.
Qualifies for funding when replacing non-compliant or unsafe systems, especially when installed with insulation.
Without smart controls or off-peak use, costs can rise quickly.
Poorly insulated properties may find electric heating expensive to run.
Consumer units or dedicated circuits might need upgrading.
Can’t be installed as a standalone measure — must follow PAS 2035 planning.
You may be eligible under PAS 2035 if:
Storage and panel heaters are safe, modern, and highly suitable electric heating solutions— especially for homes without access to gas. Under the PAS 2035 framework, they must be part of a fabric-first, whole-house retrofit, ensuring the system is effective, energy-efficient, and fully compliant.
With grants available through ECO4, GBIS, and other schemes, electric heating upgrades are now more accessible— helping households cut energy costs and carbon emissions without compromising on comfort.
