Plastered In Infrared Heating

How does our invisible plastered in heating heat your home? 

At ASTECtherm, our plastered-in infrared heating provides a completely hidden, highly efficient way to warm your home. Discreetly embedded within your walls or ceiling, this system emits safe infrared radiation—similar to the natural warmth of the sun—which is absorbed by the surfaces and objects in the room, rather than just the air.

Once absorbed, these surfaces—walls, floors, furniture—slowly release heat back into the space, creating a consistent and comfortable environment. Because our heating film operates at surface temperatures between 24°C and 36°C, it doesn’t rely on convection to warm the room. Instead, it emits gentle infrared light, warming you and your surroundings directly, without moving air or creating drafts.

The result is a clean, even heat that feels more natural and is free from the circulation of dust or allergens. And because it warms surfaces directly, your space reaches a comfortable temperature faster—allowing the system to switch off sooner, saving energy in the process.

With ASTECtherm’s plastered-in infrared heating, you get an elegant, invisible heat source that delivers high performance, energy efficiency, and real comfort—all without a radiator in sight.

Property in Rugby

One of our clients asked for a quote for ASTECtherm Low Energy Infrared Space Heating for his 200-year-old 2 bedroom property.  Once ASTECtherm received the plans a system design and quote were produced and forwarded to our client for consideration and comment.

After a couple of weeks, we made our customary follow-up call to see if the client had any questions about either the system or the quote.  It turned out that our client, a senior consultant engineer, had been investigating and comparing Air Source and Ground Source heat pump options, panel radiators and infrared panels, as well as the ASTECtherm.  When we asked him what he thought about our proposal, his words were clear and unambiguous, “you have THE best heating option on the market, when can you deliver?”; “there is no competition, can I buy some shares?”

Install day

The client wanted some assistance installing the heating so paid for a day with our install team.  After showing the client the product, work quickly progressed with cables routed and then paired in accordance with the system schematic (provided by ASTECtherm with the system) ready for crimping to the heating mats.

The plasterer mixed up Multi Finish Plaster and applied a bed of plaster ready to accept the first mat. This mat was connected to the prepositioned cable and then rolled out and pushed in to plaster.

Over the next hour the pre-cut mats (mats are crimped and cut to length as part of kit production) for this first bedroom went in without issue in accordance with the schematic.  Onto the en-suite …  this time 4 mats installed in the walls – Done!

Onto the main bedroom and second en suite.  A few hours later upstairs was complete ready for the plaster to make everything look pretty. Overall the installation of the ASTECtherm system in this property took just 7 hours.

The next hour the mats for the bedroom went in like a dream, then onto the en suite … 4 mats installed in the the walls – Done!

Onto the main bedroom and second en suite, a few hours later upstairs was complete ready for the plaster to make everything look pretty.
