Hydronic Radiators

Our hydronic radiators use hot water systems for efficient space heating. The heavy steel construction retains and radiates heat long after reaching temperature, reducing cycling and energy consumption. Ideal for both new construction and retrofit projects, these systems integrate seamlessly with existing boilers or heat pumps while maintaining architectural aesthetics.

Electric Radiators

UL/CSA-certified electric heating panels provide 100% energy efficiency through thermal storage. The steel construction continues radiating heat after reaching set points, minimizing on/off cycling. Suitable for supplemental heating or primary systems in residential and commercial spaces where hydronic infrastructure isn't available.

Steam Radiators

Specialized steam heating solutions engineered for commercial and institutional buildings. These systems leverage existing steam infrastructure while incorporating modern design elements. Available in multiple configurations to match heritage aesthetics or contemporary architectural requirements without compromising thermal performance.

Thermostats and Controls

Wi-Fi enabled smart thermostat solutions for optimal temperature management. The RST thermostat enables remote programming and zoning capabilities to maximize comfort while minimizing energy consumption. Designed to work seamlessly with all Runtal heating systems for integrated performance monitoring and adjustments.

Accessories

Comprehensive accessory packages including thermostatic valves, shut-off systems, and mounting hardware. These components ensure proper system operation, maintenance accessibility, and aesthetic integration with building interiors. Engineered specifically for Runtal systems to guarantee compatibility and long-term performance.

Questions

What types of heating systems do you manufacture?

We produce hydronic, electric, and steam radiator systems including baseboard panels, wall-mounted units, vertical panels, and towel radiators for residential and commercial applications.

Are your electric radiators more efficient than traditional models?

Yes, our electric radiators achieve 100% efficiency through thermal storage technology that continues heating after reaching temperature, reducing cycling by up to 40% compared to conventional units.

Can I install your products behind furniture?

Our electric baseboard and wall panels require minimum 2-inch clearance from furniture or drapery for safe and effective operation as specified in installation guidelines.

Do your electric radiators have built-in thermostats?

We recommend using our Wi-Fi enabled RST smart thermostat instead of unit-mounted controls for more accurate whole-room temperature management and energy optimization.

What warranty do you offer?

All products carry a 20-year limited warranty covering manufacturing defects and performance issues when installed according to our technical specifications and local building codes.

Can I return standard products?

Stock items in standard RAL 9010R white finish may be returned within 90 days with 20% restocking fee, provided they're in original packaging and unused condition.

Very happy with the service & quality of my steam radiators! Fun to look inside the factory where they were made when we went to pick them up!

Their radiators are beautiful and solid. The Sales department is very helpful on the phone. However their website is poorly organized. The radiator model numbers are not explained well on the site.and challenging it understand the differences between UX, VX, VLX etc.
UF (Universal Fit) in stock series hydronic radiators in set sizes (height and length) based on standard pressure (no more than 56 PSI) and pre-drilled for up to 8 different piping configurations.
VLX model Custom made units that ranges from 1 to 10 panels high and 20 up to 296 in a single run. VX custom made

For anyone who read my previous rating. It was as I had expected. One person causing trouble in a great company that is fair, responsible and attentive. Wanda needs to learn to be more professional from those that have been there longer. I received an email from Jon Wiberg the person who originally sold us our radiators. He has worked at Runtal long enough to know Steves Father who died almost 20 years ago. The first thing he said was that he was prepared to send out a check. All he needed was the invoice that showed the $225 for the plumbing company coming out a second time. Of course this

We have Runtal towel dryer/radiator. It is awesome. The bathroom is always nice and warm in the morning and our towels are always dry, even with multiple showers a day. The unit did stop working recently. I reached out to Runtal and they responded right away and replaced it under warranty without question. The new one is here, an exact match for the original unit and we are back to nice warm towels. I appreciated the great customer service!

Unfortunately absolutely horrible customer service in my opinion. I purchased a 2'x2' wall radiator directly from Runtal thinking it would be best and I'd have the best experience straight from the company. The day the unit arrived, I Googled for a diagram of fitting sizes as my package did not contain any literature. 2 separate 3rd party distributors had the same unit on sale for $330 less than I paid. I called Runtal and they would not work with the price I had paid. They were happy to have me either return the unit I got from them (eating shipping costs both directions) or drive it to their

Original swiss designed radiators that are beautiful. Have updated and expanded our 1955 home including hydronic replacements and electrical radiators in the addition. The extra money over the builder quality radiators was well worth the cost. Highly recommended.
