Heat pumps are the most popular choice for heating homes in New Zealand, and they are known for their efficiency and convenience. However, for those that don’t like the appearance or the type of warm air produced by heat pumps, there are other options available to homeowners. Whether you’re seeking alternatives due to your home's specific requirements, personal preferences, or budget considerations, it's essential to explore all the heating options available. This article will delve into five alternative heating systems: hydronic (air-to-water) systems, wall panel heaters, wood burners, gas fires, and underfloor electric heating.
HEAT PUMP ALTERNATIVE 1: HYDRONIC (AIR TO WATER) SYSTEMS
Hydronic heating or air-to-water systems are an excellent alternative to traditional heat pumps. These systems work by transferring heat from the air outside to water, which is then circulated through pipes to radiators, underfloor heating, or convectors within the home.
How It Works
An air-to-water heat pump extracts heat from the outside air and uses it to heat water. This heated water is then pumped through a network of pipes to radiators or underfloor heating systems, providing consistent and comfortable warmth throughout the home. The system can also heat domestic hot water, making it a versatile and efficient option.
Benefits
Energy Efficiency: Hydronic systems are highly energy-efficient, especially when paired with underfloor heating. They use renewable energy sources, making them an eco-friendly option.
Comfort: These systems provide even and consistent heating, avoiding the hot and cold spots often associated with other heating methods.
Versatility: Hydronic systems can be used for space heating and domestic hot water, offering a comprehensive solution for home heating needs.
Considerations
Purchase and Installation Costs: The initial purchase and installation cost can be very high, particularly if retrofitting an existing home.
Maintenance: Regular maintenance is required to keep the system running efficiently.
Space Requirements: The system requires space for the outdoor unit, water tanks, and piping infrastructure.
HEAT PUMP ALTERNATIVE 2: WALL PANEL HEATERS
Wall panel heaters are a good choice for those looking for a straightforward and low (upfront) cost heating solution. These heaters are mounted on the wall, providing radiant and convection heat to the room.
How It Works
Wall panel heaters work by heating the air that comes into contact with the panel's surface. As the air warms up, it rises and circulates throughout the room, creating a consistent and comfortable temperature.
Benefits
Easy Installation: Wall panel heaters are easy to install and can be mounted on any wall with access to an electrical outlet.
Low Maintenance: These heaters require minimal maintenance, making them a hassle-free heating option.
Compact Design: Wall panel heaters are slim and compact, making them ideal for homes with limited space.
Considerations
Heating Capacity: Wall panel heaters are best suited for small to medium-sized rooms. They may struggle to provide adequate heat for larger spaces.
Energy Consumption: While modern wall panel heaters are more energy-efficient than older ones, they can still be costly to run continuously.
Temperature Control: Some models struggle with temperature control, making it harder to maintain a consistent temperature.
HEAT PUMP ALTERNATIVE 3: WOOD BURNERS
Wood burners, or wood stoves, have been a traditional heating method in New Zealand for many years. They provide a rustic and cosy atmosphere while delivering powerful heating.
How It Works
Wood burners generate heat by burning mainly wood logs. The heat is then radiated into the room, providing warmth. Modern wood burners are designed to be highly efficient, with some models featuring secondary combustion technology to burn wood more entirely and reduce emissions.
Benefits
Cost-Effective: Wood is a relatively inexpensive fuel source, especially if you have access to free or low-cost wood.
Eco-Friendly: When sourced sustainably, wood is a renewable energy source. Modern wood burners also have lower emissions compared to older models.
High Heat Output: Wood burners can generate significant heat, making them suitable for larger spaces and open-plan living areas.
Considerations
Storage: You need a large, dry area to store firewood, which can be heavy and bulky.
Maintenance: Regular cleaning of the stove and chimney is necessary to prevent buildup and ensure efficient operation. Ash typically needs removing after some time, and cleaning glass panels is time consuming and energy-intensive.
Initial Cost: The cost of purchasing and installing a wood burner can be high.
HEAT PUMP ALTERNATIVE 4: GAS FIRES
Gas fires are a convenient and efficient alternative to heat pumps. They offer the ambiance of a traditional fireplace without the hassle of fireplace cleaning, wood storage and handling.
How It Works
Gas fires produce heat using natural gas or LPG. They can be installed as freestanding units, built into a wall, or retrofitted into an existing fireplace. Modern gas fires often have remote controls and programmable thermostats for ease of use.
Benefits
Convenience: Gas fires are easy to operate with a simple switch or remote control, providing instant heat.
Clean and Efficient: Gas fires burn cleanly, producing fewer emissions than wood burners and requiring less maintenance.
Aesthetic Appeal: Many gas fires are designed to mimic the look of traditional wood-burning fireplaces, providing a cosy and attractive focal point in the room.
Considerations
Running Costs: The cost of gas can fluctuate significantly, impacting the running costs of gas fires. The uncertainty of long term gas supply in NZ is also a consideration
Installation cost: Professional installation is required, which can add to the initial purchase cost.
Ventilation: Proper ventilation is necessary to ensure safe operation and prevent the buildup of harmful gases.
HEAT PUMP ALTERNATIVE 5: UNDERFLOOR ELECTRIC HEATING
Underfloor electric heating is an increasingly popular choice for modern homes. It offers an invisible and efficient way to heat living spaces.
How It Works
Electric underfloor heating systems consist of heating cables or mats installed beneath the floor surface. When the system is turned on, the cables or mats heat up, warming the floor and, subsequently, the room, through radiant heat.
Benefits
Comfort: Underfloor heating provides a comfortable and even heat distribution, eliminating cold spots.
Space-Saving: With no visible heaters or radiators, underfloor heating frees up wall and floor space, allowing for a more flexible interior design.
Zoning: Underfloor heating systems can be zoned, allowing you to heat specific areas of your home as needed, enhancing energy efficiency.
Considerations
Installation Cost: Underfloor heating installation can be costly, particularly in existing homes where floors need to be lifted.
Energy Consumption: While efficient, electric underfloor heating can be expensive to run, especially in larger areas.
Response Time: Underfloor heating systems can take longer to warm up compared to other heating methods, so they may not be ideal for quickly heating a space.
Conclusion
When considering alternatives to heat pumps, it’s crucial to evaluate your home's specific needs, budget, and personal preferences. Each of the options discussed—hydronic systems, wall panel heaters, wood burners, gas fires, and underfloor electric heating—offers unique advantages and considerations. By understanding these options, you can make an informed decision that ensures your home remains warm and comfortable throughout the colder months in New Zealand.
