How Will Electric Radiators Perform in a Poorly Insulated Property?

Worried that your home’s insulation isn’t good enough for electric heating? 

You’re not alone. Many homeowners assume electric radiators only work in well-insulated properties. The good news? That’s not true.

The Truth About Insulation and Electric Heating

Poor insulation doesn’t mean electric heating won’t work, it just means you need the right size radiator for your space.

 At Trust Electric Heating, we don’t use a one-size-fits-all approach. Every NEOS electric radiator is calculated specifically for your room based on an efficiency factor.

What Is an Efficiency Factor?

An efficiency factor takes into consideration:

• Your property’s insulation levels

• The type and quality of your glazing (single, double, or triple)

• The nature of your property (period build, modern construction, etc.)

• Room size and ceiling height

• External walls and heat loss points

If your property has poor insulation, we increase the efficiency factor. This means we’ll recommend a larger radiator with higher kW output to compensate for heat loss. The result? Your radiator performs optimally, even in challenging conditions.

Why This Matters

Many electric heating companies use generic calculations that don’t account for your property’s specific characteristics. This leads to undersized radiators that struggle to heat poorly insulated rooms, leaving customers disappointed.

At Trust Electric Heating, we take the time to assess your property properly. Our heating engineers measure your space, evaluate insulation, and calculate exactly what you need. No guesswork. No generic recommendations.

Real-World Performance

The NEOS electric radiator is designed to work across diverse property types, from Victorian terraces with solid walls to modern homes with cavity insulation. Our patented soapstone core technology stores heat efficiently and releases it gradually, which is particularly beneficial in poorly insulated properties where heat loss is higher.

Because the NEOS continues warming your room even after it switches off, you’re not constantly fighting heat loss with continuous electricity consumption.

What If You Improve Insulation Later?

If you upgrade your insulation after installing NEOS radiators, they’ll simply run more effectively. The radiators will cycle on and off less frequently, reducing your running costs further. It’s a win-win situation.

The Bottom Line

Poor insulation doesn’t disqualify you from electric heating. With the right calculations and properly sized radiators, the NEOS electric radiator will perform optimally in your home, regardless of insulation levels.

Since 2014, thousands of customers across the UK have chosen Trust Electric Heating for honest assessments and heating solutions that actually work.
