Hydronic heating guides & blog
Installer-grade hydronic buying guides.
Honest, technical buying advice from AHHAC's licensed hydronic engineers — cost, COP, ROI and brand comparisons to help you specify the right system for your Australian home.

STCs, NSW, VIC, QLD and ACT programs explained — what's covered, what isn't, and how gas-to-electric upgrades are funded.
Comfort, running costs, install cost, lifespan and the real downsides — and who should choose something else.
Install cost, running cost, comfort, noise and cooling compared — plus when a combined system makes the most sense.
Low pressure, cold radiators, noisy pipes and boiler lockouts — safe checks, how to bleed a radiator and when to call us.
Heat-loss basics, indicative W/m² by climate, ΔT and heat-pump derating, and K11–K33 panel types explained.
A worked annual-cost example, tariffs, the solar multiplier and how to cut your ACT heating bill.
Step-by-step: heat-loss assessment, radiators vs in-screed underfloor, heat source, pipe routing, disruption and cost.
Two Italian hydronic systems compared — running cost, cooling, hot water, flow temperature and best-fit.
Warm-up speed, comfort, running cost, install cost, retrofit and cooling — how to choose the right emitter for your home.
Real 2026 install and running-cost figures — underfloor vs radiators, heat pump vs gas, rebates, and how to get an accurate quote.
How to specify hydronic in a genuinely cold climate — heat source, emitters, sizing, running costs and the ACT's move to all-electric.
An honest look at whether hydronic pays off up north — and the reversible heat-pump decision that changes the maths.
How underfloor and fan-coil cooling work, the humidity question, cost vs ducted AC, and adding cooling to existing hydronic.
Electric heat pump or condensing gas boiler? Running cost, cooling, flow temperature and best-fit compared.
What a system costs in 2026, how to read COP, running costs by climate, and Maxa vs Viessmann vs Immergas.
Real 2026 install pricing for in-slab and in-screed underfloor, what drives the cost, and how heat pumps cut running cost.
Upfront cost, running cost and best-fit — when a simple electric boiler wins and when a heat pump pays for itself.
R290 vs R32, COP, output, cold-climate rating and best-fit — how to choose between the two Maxa hydronic heat pumps.
Realistic ROI and payback, how to size the array and thermal store, and pairing solar with a heat pump or gas backup.
An independent, installer-grade comparison of the three brands AHHAC carries — COP, refrigerant, output and warranty.
