Central Heating Installation & Repairs – Manawatu / Whanganui

Why choose central heating?

Central heating delivers whole-home warmth from a single heat source—usually a gas, diesel or electric boiler feeding radiators, under-floor coils or a ducted air system. In a temperate but changeable region like Manawatu / Whanganui, consistent indoor temperatures improve health, protect building materials from moisture and reduce condensation.

Key system types

• Hydronic radiators: Fast response, individual room control, ideal for retrofits.
• Under-floor hydronic: Invisible and silent; pairs well with polished concrete slabs in new builds.
• Ducted air: Uses warm air instead of water; can combine with cooling.

Installation workflow

1. Heat load calculation: Your installer will model insulation levels, window sizes and local climate to size the boiler correctly.
2. Distribution layout: Radiator placement or under-floor coil spacing is mapped to ensure even heat.
3. Boiler & controls: High-efficiency condensing boilers with smart thermostats meet the latest NZ Building Code H1 energy efficiency requirements.
4. Commissioning & balancing: Each circuit is purged of air and balanced for flow before hand-over.

Cost factors in Manawatu / Whanganui

Expect installation costs to range from $11,000–$18,000 for a three-bedroom hydronic radiator system, excluding the boiler. Variables include:

• House size and layout complexity
• Boiler fuel type and efficiency rating
• Pipe run lengths and floor coverings
• Accessibility for retrofits versus new builds

Maintenance & repairs

Annual servicing keeps efficiency high and extends component life. Typical tasks include:

• Boiler flue inspection & combustion analysis
• Pressure vessel and pump checks
• Radiator bleeding and inhibitor top-ups

Common repairs—such as circulating pump replacement or thermostat upgrades—are usually quick and cost-effective when done by a qualified technician.
