Hydronic Radiant Heat Control Panel 2-Zone
This pre-assembled hydronic heating panel includes essential components for easy installation and future service. Best for homes planning radiant floors in two zones or small-scale snow-melt setups. It supports glycol systems and offers 1″ copper boiler connections with ¾” copper manifolds, simplifying boiler connections and flush/fill tasks.
Who it’s best for: contractors or diligent homeowners who want a turnkey panel with room for expansion and professional-grade components. Why selected: it consolidates control and circulation parts in one unit, reducing on-site assembly time.
Caution: exact fitment depends on compatible valves and thermostats; ensure your boiler and distribution manifolds align with the 1″ and ¾” copper connections.
De’Longhi Dragon Digital Oil Filled Radiator Heater
Designed for rapid, whole-room warmth with a larger radiant surface area, this space heater heats quickly and distributes warmth efficiently. It includes a digital control panel and a 24-hour timer for programmable heating cycles.
Best for: smaller living spaces or rooms needing fast heat with simple operation. Why selected: the enhanced radiant surface area translates to quicker warmth compared to standard oil-filled units.
Caution: intended for indoor use; ensure there is adequate clearance around the unit for safe operation.
De’Longhi Oil Filled Radiator Heater (EW7707CM)
This model emphasizes simple controls and energy-saving features, including ComfortTemp to automatically maintain room temperature efficiently. It also uses a design that promotes heat flow while maintaining a low surface temperature for safety.
Best for: users seeking steady, energy-efficient heat in bedrooms or offices. Why selected: automatic temperature management helps reduce energy use without sacrificing comfort.
Caution: performance benefits rely on stable room insulation; in very drafty spaces, results may vary.
Honeywell Aube TH140-28-01-B Hydronic Thermostat
This 7-day programmable thermostat is versatile for millivolt to 240 V hydronic systems, including hot water heating. It aims to minimize temperature swings and allows selectable cycles to optimize a heating system’s performance.
Best for: homes with hydronic floor heating or hot water systems needing precise, programmable temperature control. Why selected: it provides flexible scheduling and compatibility with a broad range of hydronic setups.
Caution: ensure your system voltage matches the thermostat’s specification to avoid compatibility issues.
Pelonis Oil Filled Radiator Heater (2026 Upgraded)
Equipped with 360-degree all-around heating and 7 fins, this unit aims for faster, more even warmth. It features multiple heat modes (including energy-saving options) and overheat and tip-over protection for safety.
Best for: large rooms or open-plan living areas needing consistent warmth. Why selected: the 360° heating design helps distribute warmth more uniformly than compact models.
Caution: higher wattage units require appropriate electrical supply and space for ventilation; avoid placing near curtains or furniture.
Buying Guide
What kind of radiant heat project do you have?
- Two-zone or multi-zone radiant floor projects benefit from pre-assembled panels like the Hydronic Radiant Heat Control Panel 2-Zone for simplified wiring and future expansion.
- For quick room warming, consider oil-filled radiators with large radiant surfaces, such as the De’Longhi Dragon Digital model or the Pelonis unit, which deliver rapid warmth with minimal setup.
How important are programmable controls?
- Thermostats like the Honeywell Aube TH140-28-01-B offer advanced control to minimize temperature swings and optimize energy usage, especially when paired with a hydronic system.
- Look for a model that supports your existing wiring voltage and offers scheduling capabilities that fit your routine.
What safety features matter most?
- Overheat protection, tip-over switches, and low surface temperatures are key for households with kids or pets. The Pelonis and De’Longhi units emphasize safe operation via these features.
- For hydronic panels, ensure solid construction, reliable valves, and professional installation when integrating with a boiler or water heater.
How do efficiency and operating costs come into play?
- Models offering ComfortTemp or auto-maintenance modes help manage energy use without sacrificing comfort. Consider room insulation and draft reduction when comparing efficiency claims.
- Choose a heater with adjustable wattage to match room size and heating needs rather than running at full power constantly.

Frequently Asked Questions
- What is the difference between an electric boiler and an electric radiator?
- An electric boiler typically heats water in a hydronic system to circulate through floors or radiators, while an electric radiator heats air directly to warm a space. Both can be part of radiant heating setups depending on your system design.
- Can these units be used for snow melt?
- Yes, certain hydronic panels and compatible boilers support snow-melt configurations when correctly connected to the correct zone and manifold setup.
- Do these products require professional installation?
- Some units are designed for easy DIY installation, especially pre-assembled panels, while hydronic systems and thermostats may benefit from professional wiring and system integration.
- Are programmable thermostats compatible with all hydronic systems?
- Most programmable thermostats support a wide range of hydronic setups, but always verify voltage, resistance, and wiring compatibility with your specific system.
