As self-builders continue to embrace low-carbon, all-electric homes, choosing a heating system that delivers both comfort and energy efficiency has never been more important. Electrorad’s Thermastore HHR Storage Heater has been developed to meet this demand, offering intelligent heat storage, flexible control and recognised SAP performance.

Unlike traditional storage heaters, Thermastore uses advanced High Heat Retention (HHR) technology to store heat during off-peak electricity periods and release it gradually throughout the day, helping homeowners maximise lower-cost electricity tariffs while maintaining a comfortable indoor environment.

A key advantage for self-build projects is that Thermastore models are listed on the SAP Product Characteristics Database (PCDB). SAP assessments play an important role in calculating the energy performance of new homes and contribute towards a property’s Energy Performance Certificate (EPC). Selecting heating products with recognised SAP data can help ensure energy calculations accurately reflect the performance of the installed system.

Thermastore also features intelligent digital controls, with optional Wi-Fi connectivity for convenient smartphone operation. Available as a single-feed solution, it removes the need for separate off-peak and peak electrical supplies, simplifying installation without compromising performance.

With no boiler, pipework or annual servicing required, Thermastore is an ideal heating solution for self-builders looking for a modern, low-maintenance alternative to traditional wet heating systems.
