Boilers

Featuring the best boilers in New Zealand

Boilers are a crucial component of home heating systems, providing reliable and efficient hot water heating using gas, diesel, wood pellet, combination (combi), steam or electric. This hot water is distributed through radiators via a network of pipes, ensuring consistent heat throughout the building during winter. The critical components include the combustion chamber, where air induces combustion, and the heat exchanger, which transfers heat to the water. Boilers are an important part of a broader range of high-quality hot water heating systems from trusted suppliers in New Zealand.

Types of boilers 

Gas 

Natural gas boilers are popular in New Zealand's urban areas due to their efficiency and low operating costs. In regions without natural gas, LPG Boilers are a suitable alternative, functioning similarly but using liquefied petroleum gas.

Diesel

Diesel boilers are known for their efficiency and low emissions, modern diesel boilers are a greener option than traditional diesel boilers. They are often used in rural areas where other gas options are less available.

Wood pellet 

These use renewable wood pellets and are highly efficient. They are suitable for both residential and commercial applications and provide a sustainable heating option with low carbon emissions.

Combination (combi) 

These provide both central heating and hot water without needing a separate hot water cylinder or cold water tank. They are compact and suitable for homes with limited space.

Steam 

A steam boiler is a device that heats water to generate steam, which is used for heating or industrial processes. It burns fuel to produce steam, which is distributed through pipes to radiators or machinery.

Electric 

An electric boiler uses electricity to heat water for domestic use and central heating. It passes an electric current through heating elements, which heat the water circulated throughout the home.

How to choose a boiler

When choosing a hot water boiler, consider the different types as mentioned above. Assess the fuel type—natural gas, oil, electric, or LPG—based on availability and cost. Opt for high-efficiency models to save on energy bills and reduce your carbon footprint, ensuring the capacity meets your home's needs. Factor in space considerations, installation complexity, and maintenance requirements. Look for advanced features like programmable thermostats and smart controls. Balance initial cost with long-term savings and consider available grants or rebates. Choose one with a good warranty and reliable customer support, and consider its environmental impact by opting for high-efficiency, low-emission models.

Ongoing maintenance

Ongoing maintenance for boilers is essential to ensure efficient and safe operation. Regular tasks include inspecting and cleaning the boiler's components, such as burners, heat exchangers, and controls, to prevent the buildup of dirt and debris that can affect performance. It's essential to check and replace filters and valves as needed to maintain proper water and gas flow. Additionally, annual servicing by a qualified technician is recommended to conduct thorough inspections, test safety mechanisms, and address any potential issues before they become costly repairs. Proper maintenance not only extends the boiler's lifespan but also ensures it operates at peak efficiency, reducing energy costs and minimising the risk of breakdowns.

Other hot water heating products you might want to consider

Hot water systems come in many different forms, each catering to various needs and preferences. For those seeking easy installation, an electric water heater is an ideal choice. If environmental friendliness is a priority, a solar hot water system is a great option. Homeowners looking for lower operating costs should consider air-to-water heat pumps, which often come with government subsidies to further enhance their affordability.
