FAQs

Question 1

How much does a central heating install cost in Manawatu / Whanganui?

Accepted Answer

For an average 150 m² home, expect $11k–$18k for hydronic radiators or $18k–$25k for under-floor systems, including boiler and GST. Complex layouts or premium designer radiators can add 10–20 %.

Question 2

Which boiler fuel is most economical here?

Accepted Answer

Natural gas is cheapest where reticulated supply exists (mainly Palmerston North). In rural areas, diesel or LPG are common. High-efficiency electric boilers become cost-competitive when paired with solar PV.

Question 3

Can I retrofit radiators into a 1920s villa?

Accepted Answer

Yes. Slim-line radiators and surface-run piping make hydronic retrofits straightforward. Your installer will verify floor joist strength and locate discreet pipe routes to preserve character details.

Question 4

How often should the system be serviced?

Accepted Answer

Annual servicing is recommended: boiler inspection, system flush, inhibitor dose and control calibration. This maintains warranties and prevents costly corrosion or pump failure.

Question 5

Is central heating compatible with heat pumps?

Accepted Answer

Absolutely. An air-to-water heat pump can replace or supplement a gas or diesel boiler, delivering low-carbon heat to the same radiator or under-floor circuit.
