Central Heating Installation & Repairs – Wellington

Why choose central heating in Wellington?

The Capital’s changeable climate—temperatures that can drop suddenly, prevailing southerlies and damp winter months—makes whole-home heating more than a luxury. A professionally designed and installed central heating system delivers:

• Even temperatures in every room, eliminating cold spots.
• Better air quality by reducing condensation and mould.
• Energy efficiency—modern boilers and heat sources can cut running costs compared with multiple space heaters.

Key system types

Hydronic radiators

Hot water circulates through wall-mounted panels, providing gentle, dust-free warmth. Ideal for villas and character homes where ductwork is hard to conceal.

Ducted warm-air systems

Centralised heat pumps or gas furnaces distribute heated air via ceiling or under-floor ducts. They warm quickly and can incorporate cooling for year-round comfort.

Under-floor hydronic

Pipes embedded in the slab or screed radiate low-temperature heat upwards—perfect for new builds or major renovations aiming for maximum efficiency and invisible hardware.

Installation checklist

1. Heat load calculation: A qualified HVAC designer will assess insulation, glazing, orientation and occupancy to size your system correctly.

2. Fuel choice: Compare natural gas, diesel, LPG, biomass or electric heat pumps. Each has trade-offs in running cost, carbon footprint and availability.

3. Zoning: Split living and sleeping areas so you only heat the spaces in use.

4. Controls: Smart thermostats and weather compensation maximise savings by adjusting output automatically.

5. Compliance: Ensure the design meets New Zealand Building Code clause H1 for energy efficiency. For official guidance, see MBIE’s resource on H1 Energy Efficiency.

Typical costs in Wellington

• Hydronic radiators: $12,000 – $25,000 for a 150 m² home.
• Ducted heat pump system: $8,000 – $18,000 depending on capacity and zones.
• Under-floor hydronic: $90 – $130 per m² installed (new slab).
• Annual servicing: $250 – $450, including safety checks and efficiency tuning.

These figures are indicative; request itemised quotes from multiple installers via ArchiPro for accurate budgeting.

Maintenance & repairs

Regular servicing extends system life and avoids unexpected breakdowns during a cold snap. Key tasks include:

• Bleeding radiators and checking pump pressure.
• Inspecting heat exchangers for corrosion.
• Cleaning filters and ductwork.
• Updating firmware on smart controllers.

If your system is more than 15 years old, retrofitting a high-efficiency boiler or inverter heat pump could slash energy use by up to 30%.

Choosing the right Wellington professional

When comparing providers, look for:

• Certifications: Gasfitters, Plumbers and Drainlayers Board registration, or Refrigerant licence for heat pump work.
• Local experience: Familiarity with Wellington’s seismic considerations and coastal corrosion.
• Transparent quoting: Clear breakdown of equipment, labour, electrical and consent fees.
• After-sales support: Emergency call-out times and warranty processes.
