Hydronic Radiators — De'Longhi & IMAS

Hydronic radiators Sydney and Australia-wide — De'Longhi (our first-preferred supplier) and IMAS Group panel, tubular and column radiators, plus designer towel rails and sculptural pieces. Paired with MAXA smart thermostats for per-room control.

De'Longhi Radel steel panel radiator

A radiator can be a heating appliance OR a piece of furniture. Modern hydronic radiators include slim panels (50mm deep), tall towers, vertical sculptural pieces, and beautifully restored cast-iron column units.

AHHAC's first-preferred radiator supplier is De'Longhi — Italian-engineered panel and column radiators with premium build quality. Our second range is the IMAS Group catalogue, covering tubular and flat-panel radiators across an extensive size range. We size each unit to room heat loss and pair it with the right thermostatic valve (TRV) — and where smart, per-room scheduling is wanted, we add the MAXA wall thermostat range for full app and smart-home control.

FAQs

Common questions

What's the difference between cheap and premium radiators?

Premium European radiators (Zehnder, Bisque) use higher-grade steel, better factory paint, closer manufacturing tolerances and often double-stripped for better aesthetic. Output is similar; longevity, finish and looks differ significantly. Both work — your call.

Towel rail or panel radiator for bathroom?

Towel rail does both: heats the room AND warms towels. Most bathrooms only need one. We size to room heat loss and recommend a dual-purpose towel rail with optional electric element for summer towel-warming when the heating's off.

Cast iron column radiators — do they still work?

Yes — modern cast-iron column radiators are made specifically for hydronic systems with appropriate heat output figures. They look stunning in heritage and period homes, and last 50+ years. Slower to heat up than steel panels but pleasant heat character.

Which hydronic radiator brands does AHHAC install?

Premium European hydronic radiators led by De'Longhi and IMAS, plus designer vertical panels, restored cast-iron column radiators for heritage homes, and heated towel rails. We size every unit to the room's calculated heat loss so the system is neither starved nor oversized.

How quickly do hydronic radiators heat a room?

About 15–25 minutes from cold — far faster than underfloor, which takes several hours. That makes radiators ideal for bedrooms, studies and rooms used intermittently, where you want heat on demand rather than a slow background warmth.

"AHHAC delivered our 22-zone underfloor system on time, on budget and to spec. The crew were tidy, the documentation was thorough, and the commissioning was textbook."

"We've worked with AHHAC for 17 years. They've installed and serviced our hot water plant across three commercial buildings — and they pick up the phone on weekends."

"Three mobs quoted us; AHHAC's design was the only one based on a proper heat-loss calculation. The system runs beautifully — the others would've been oversized and expensive."
