European hydronic panel radiators, designer verticals and towel rails for Canberra homes — quick to warm each room, easy to retrofit, and sized for the ACT's genuinely cold winters. Designed and installed by AHHAC from our Fyshwick showroom and quoted within 24 hours.
Hydronic radiators in Canberra give fast, room-by-room warmth through the ACT's cold winters: a European panel warms a room from cold in 15–25 minutes, and a whole-home retrofit usually takes one to three days with no floor works. Sized generously to Canberra's design temperature, panels running at 45–55 °C pair efficiently with a cold-rated Maxa i-290 heat pump. AHHAC installs De'Longhi and IMAS radiators across the ACT from our Fyshwick showroom.

ImmergasSimeThermaSkirt™Hydronic radiators are the most flexible way to bring hydronic heating into a Canberra home — and in the coldest capital in Australia, their speed is a real advantage. Warm water from a heat pump or boiler circulates through slim, wall-mounted panels that heat each room quickly and quietly, with a thermostatic valve on every unit so you control the temperature room by room. For a Canberra winter — where you want a study or bedroom warm within minutes on a −4 °C morning — that fast response is exactly what you need. This page is part of our wider hydronic heating Canberra service, run from our Fyshwick showroom.
Radiators are also the easiest hydronic system to retrofit, which matters in Canberra's established inner-south and inner-north suburbs full of solid brick and mid-century homes. Using a discreet "manifold and home-run" pipe layout — single pipes from a central manifold to each radiator with no joins in walls — a typical Canberra install takes one to three days with no slab work. Sized correctly to the ACT's cold design temperature, modern European panels deliver ample output even on the coldest days. See the emitter detail on our hydronic radiator heating page and the range on our radiators page.
Whether you're after hydronic radiator panels for a renovation, De'Longhi or IMAS radiators for a new build, or a designer vertical for a feature wall, AHHAC sizes each radiator to the room's heat loss and installs a balanced, quiet system powered by an efficient, cold-rated heat pump.
In a cold climate, the ability to warm a room fast is genuinely useful. Unlike in-slab underfloor, which takes hours to come up to temperature and is designed as a steady background warmth, a European panel radiator warms from cold in 15–25 minutes — so you can heat the rooms you're using, when you're using them, without running the whole house all day. Each radiator's thermostatic valve holds its own set point, so bedrooms, studies and living areas each run independently. For Canberra homes that aren't occupied all day, that responsiveness translates directly into lower running cost.
Radiator output falls as the outdoor temperature drops and as the flow temperature is lowered for heat-pump efficiency, so in Canberra the panels must be sized generously to the ACT's cold design temperature. Under-size them and the room never reaches temperature on the coldest days; size them correctly and they deliver comfortable, even heat while still letting the heat pump run efficiently. AHHAC runs a room-by-room heat-loss calculation on every Canberra job and selects panel sizes accordingly — the discipline our guide to mistakes to avoid explains in detail.
AHHAC supplies premium European hydronic radiators led by De'Longhi and IMAS, plus designer vertical panels, restored cast-iron column radiators for period Canberra homes, and heated towel rails for bathrooms. Slim double- and triple-panel radiators deliver high output from a compact footprint — important when sizing generously for the cold — while vertical designer radiators turn a heat source into a feature. Dual-fuel towel rails keep towels warm even in summer when the heating is off.
Modern oversized panels run happily at 45–55 °C, which lets them pair with an efficient, cold-rated heat pump — the Maxa i-290, rated to −25 °C, holds output through ACT frosts. With the ACT phasing out new gas connections, an all-electric heat-pump radiator system is the future-proof choice, though a condensing gas boiler remains a fast-response option where gas is already connected. Our Canberra running-costs guide compares them.
Underfloor gives the most even, invisible warmth for new builds; radiators give faster response and easier retrofit for existing homes. Many Canberra homes blend both — underfloor through the living areas, radiators in bedrooms and additions — all run from one heat pump. Our comparison of underfloor heating vs radiators lays out the trade-offs. From our Fyshwick showroom we cover Canberra, Queanbeyan, Bungendore and Yass; every job runs the same way — consult, heat-loss calculation and fixed-fee quote within 24 hours, in-house install, and full commissioning.

Hydronic radiators in Canberra are usually the answer when a home is already built and lived in, whether that is a solid brick house from the 1960s, a former government home in the inner north or south, or an early project home in Belconnen or Tuggeranong. Each has its own route for pipework, and where each panel sits matters as much as how big it is.
Pipe routes depend on how the house was built. Homes with a suspended timber floor are the easiest: we run insulated pipes through the subfloor and come up beside each radiator, leaving the walls untouched. Slab-on-ground homes usually take their pipework through the ceiling space and drop it inside a wall cavity. Solid masonry walls have no cavity to drop through, so we plan short, neat surface runs or come up from below wherever we can. In every case, pipes in a cold subfloor or roof space are fully insulated so the heat is not lost before it reaches the room.
Many ACT owners start with radiators in the main rooms and later add underfloor heating in Canberra during a renovation or extension, all on the one heat source. Our guide to hydronic heating running costs in Canberra compares gas and heat-pump operation, and our hydronic retrofit guide covers the wider process.

"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."
