"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."

Hydronic wood boilers and heaters that warm one room AND drive your whole-home heating. Off-grid friendly, increasingly popular for rural builds. We supply the Wiseliving wood-fired hydronic range.

A hydronic wood boiler includes a back-boiler that captures heat from the firebox and transfers it (via heated water) to your hydronic network — radiators, underfloor or skirting heating throughout the house.
Pairs beautifully with a thermal store for buffering — load the firebox in the evening, use the stored heat all night. AHHAC supplies the Wiseliving wood-fired and solar hydronic range alongside European pellet boilers.
Yes — a hydronic wood heater with back-boiler captures heat from the firebox and circulates it through your hydronic network to radiators, underfloor or skirting throughout the house. Output range 6–25 kW, depending on the unit and your home's heat loss.
Modern hydronic wood/pellet units are AS/NZS 2918 emissions compliant — well below the regulatory limits for particulate matter. Pellet auto-feed systems burn even cleaner than logs because they meter the fuel precisely. Both have lower lifecycle carbon than gas.
Annual chimney sweep and ash clean-out. Pellet units need the hopper auger checked and gasket inspection annually. We offer service contracts that include all of this — typical $250–$400/year.

"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."
