Discreet under-cabinet hydronic units that kick out warm air on demand — perfect for kitchens and bathrooms where wall space is at a premium and a 100mm kick-space is otherwise wasted.
Plinth heaters slide into the kick-space beneath your kitchen cabinets or vanity units — that 100mm gap that's normally just dust. They contain a hydronic heat exchanger and a quiet fan, kicking out warm air at floor level when called for.
They're the smartest way to heat a kitchen or bathroom without sacrificing wall space for radiators or floor space for trench heaters.
Standard kitchen kick-space is 100mm tall — most plinth heaters slide in at 80mm. They take a 600mm wide section of plinth (or two for a larger heater).
Output is typically 1.0–2.5 kW, enough to comfortably heat a kitchen or bathroom up to 25–30m². Multiple units can be deployed in larger spaces.
Most kitchen kick-spaces are 100mm tall — standard plinth heaters slide in at 80mm. They take a 600mm wide section of plinth (or two units side-by-side for a larger heater). We'll measure on site.
Typically 1.0–2.5 kW per unit — enough to comfortably heat a kitchen or bathroom up to 25–30m². For larger spaces, we pair multiple units for combined output.
30–40dB on low fan, 45–55dB on boost. Quieter than a domestic dishwasher or extractor fan. Modern units include a 'silent' mode for evenings.
"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."
