High Heat Retention Storage Heaters

Replace your old storage heaters with modern, efficient, electric heating

If your existing storage heaters are outdated, difficult to control or no longer suit the way you use your property, high heat retention storage heaters can provide a more flexible modern alternative.

iCozi supplies and installs Elnur HHR plus high heat retention storage heaters for electrically heated properties across Mainland UK.

A complete service from survey to installation

We don’t simply supply the heaters and leave you to arrange the rest. Our service includes:

• Free, no-obligation survey – we assess your existing heating, rooms and property requirements.
• Heat-loss calculation – we calculate the heating requirement to help determine the appropriate heater sizes.
• Electrical assessment – we check the existing electrical arrangements as part of the proposed installation.
• Solar PV assessment – if you have solar panels, we can add a solar control unit so the heaters can use surplus generation.
• Supply and installation – we supply the appropriate HHR plus heaters and install them using qualified electrical engineers approved by iCozi.
• iCozi is an Alcumus Approved Safe Contractor.
• Programming and setup – we programme the system and help you understand the controls and app.
• Post-installation telephone support – we’re available by telephone if you need help after installation.

Better control of stored heat

High heat retention storage heaters are designed to retain stored heat for longer and give you greater control over when heat is released compared with older storage heaters.

High heat retention storage heaters are required to store 45% of unused heat over 24 hours. Elnur states that its heaters store 51%.

HHR plus heaters can work with Economy 7, Economy 10 and some smart or time-of-use tariffs.

Which storage heater do I need?

HHR plus heaters can be controlled by WIFI and can use surplus solar energy with separate control boxes.

Four models are available with heat outputs of: 270W · 550W · 820W · 1,100W

The right size depends on factors including the room and its heat-loss characteristics. Your electricity tariff, meter setup and how you use your heating can also affect the most suitable arrangement.

That’s why we carry out a heat-loss calculation before recommending which heaters are suitable.

Is high heat retention heating suitable for my property?

Our HHR storage heaters are suitable for a range of electrically heated properties, including houses, flats, residential properties, social housing, commercial premises and retirement living properties.
