Central Heating Services
Unmatched Heating Expertise in the Region
Radiant warmth you can feel, quality you can see. With 20 years experience as well as European and British roots, no one in Nelson Tasman has more central heating expertise than Chapmanz.
At Chapmanz, we bring European-style comfort to New Zealand homes through expertly designed central heating systems. From elegant radiators to discreet underfloor heating and advanced heat pumps, our systems are tailored for efficiency, performance, and timeless comfort.
Radiator Central Heating Systems
There’s a reason why radiator systems remain one of the most popular ways to heat homes across Europe, and increasingly, here in New Zealand.
Radiator heating delivers quiet, even warmth without the dryness or noise of forced air. With water circulating through sleek, efficient radiators, every room feels consistently comfortable: no drafts, no cold corners.
Our radiator systems suit both modern and character homes, with styles ranging from minimalist flat panels to classic cast-iron designs, chosen to complement your home’s aesthetic as well as its warmth.
Heat Pump Central Heating Systems
Harness renewable energy for whole-home comfort with a heat pump central heating system. Using advanced air-to-water technology, these systems extract heat from the air to warm water for radiators or underfloor circuits — delivering exceptional efficiency all year round.
Ideal for modern, low-carbon living, our systems are expertly matched to your home’s design and climate. Chapmanz takes care of every detail, from design to commissioning, giving you a seamless, sustainable way to heat your home.
Hydrogen-Ready Gas Boilers
Experience quiet, even warmth with a radiator heating system powered by a Vaillant ecoTEC gas boiler. Designed for efficiency and comfort, these systems deliver steady heat throughout your home without drafts or dry air.
The Vaillant ecoTEC combines German engineering with low running costs and future-ready hydrogen capability — making it one of the smartest and most reliable heating choices for New Zealand homes.
They’re also hydrogen-ready, making them a future-proof choice as New Zealand transitions toward cleaner energy sources.
Underfloor Heating & Cooling
Enjoy warmth from the ground up with a water-based underfloor heating system designed and installed by Chapmanz. Hidden beneath your flooring, it provides gentle, even heat that transforms how your home feels — warm underfoot, efficient to run, and beautifully unobtrusive.
Perfect for new builds or major renovations, underfloor heating pairs effortlessly with heat pumps or boilers, creating a system that’s both elegant and economical.
New heat pump technology also allows your water-based underfloor heating to double as a cooling system.
At Chapmanz, we bring European comfort to New Zealand homes — quiet, efficient, and built to last.
Hot Water Systems
Enjoy reliable, energy-efficient hot water every day with a boiler or heat pump hot water system. Whether for a new build or retrofit, we size and install cylinders that deliver consistent temperature, excellent pressure, and long-term efficiency.
Our systems integrate seamlessly with your home’s central heating or operate as a standalone hot water solution, giving you comfort and performance without compromise.
Custom Commercial Systems
If you have a unique idea for your business or home, just talk to us about how we could bring it to life.

Alison McLeish, Nelson Homeowner
From the outset Chris responded promptly, professionally and with the utmost integrity. He and Fraser gave genuine advice (no hard sell) as to the best system for my needs. The quote was detailed with all specifications of the high quality products. The retro-fit installation went very smoothly, with minimum inconvenience.
I am now even looking forward to winter, in anticipation of real warmth, for the first time since arriving in Nelson seventeen years ago! I have no hesitation in recommending Chapmanz Central Heating & Plumbing.
