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.
