Underfloor Systems

Underfloor central heating and cooling is the most discrete and most comfortable form of central heating.

UNDERFLOOR SYSTEMS
Why choose Underfloor Heating for your home?

Enjoy constant temperature day and night due to less energy required to keep the temperature stable in the concrete slab, and warm floors as the heat radiates from underfoot. The system is also effectively invisible and silent, so you won’t need to compromise on interior design or wall space.

UNDERFLOOR SYSTEMS
Vaillant AroTherm Heat Pumps

Underfloor systems powered by Vaillant aroTHERM air to water heat pumps harvest free energy found in the air outside the building envelope, and convert it into all season comfort and convenience.

Underfloor Heating
In winter it circulates warm water throughout pipes encapsulated within the concrete slab floor and radiantly warms your entire home.

Underfloor Cooling
In summer it reverses the process and circulates cool water to provide background cooling.

Domestic Hot Water
All year round it generates enough hot water to meet your entire household demand.

Heat pumps from Vaillant are very quiet, powerful, energy-efficient and environmentally friendly.

– Low noise level (35dBA @4meters) ensures quiet operation for the comfort of home owners and neighbours.
– A high level of performance even when its -10°C outside.
– Ultra energy efficient and compared to a gas-fired system saves the equivalent CO2 emissions reduced by a forest area of around 2,500m2.

Engineered in Germany, Vaillant heat pumps offer world leading quality and reliability. Vaillant have more than 140 years of experience in heating systems, including 40 years in the area of heat pumps.

UNDERFLOOR SYSTEMS
Vaillant EcoTec Gas Boilers

Underfloor systems powered by Vaillant ecoTEC gas boilers are a good choice for all manner of heating and hot water loads particularly in areas with reticulated natural gas.

Underfloor Heating
In winter it circulates warm water throughout pipes encapsulated within the concrete slab floor and radiantly warms your entire home.

Domestic Hot Water
All year round it generates enough hot water to meet your entire household demand.

Vaillant ecoTEC gas boilers are a premium quality, high performance condensing boiler packed with features which result in the most reliable and lowest running cost boiler available today.

– Condensing boilers use advanced combustion technology which scavenges energy found in the flue gas that would otherwise be lost to the atmosphere resulting in running efficiencies up to 112%.
– Whisper quiet operation.
– Weather compensating control.

UNDERFLOOR SYSTEMS
Grant Vortex Diesel Boilers

Underfloor systems powered by Grant Vortex diesel boilers are a practical option particularly in areas lacking reticulated gas.

Underfloor Heating
In winter it circulates warm water throughout pipes encapsulated within the concrete slab floor and radiantly warms your entire home.

Domestic Hot Water
All year round it generates enough hot water to meet your entire household demand.

The installation of a diesel boiler is typically more involved and costly than gas boilers but offer significant running cost savings over LPG options.

Grant Vortex diesel boilers are a premium quality, high performance condensing boiler made in Ireland. They are quiet, clean burning and reliable.

– Condensing boilers use advanced combustion technology which scavenges energy found in the flue gas temperature that would otherwise be lost to the atmosphere resulting in running efficiencies up to 97%.
– Whisper quiet operation.
– Advanced digital control panel enables the boiler to automatically switch duty from heating to domestic hot water production.
– Premium quality powder coated EZI-Fit high level flue set.

UNDERFLOOR SYSTEMS
Grant Aerona3 Heat Pumps

Underfloor systems powered by Grant Aerona3 is an affordable air to water heat pump option for the single purpose of heating a medium to large home. The grant aerona3 harvests free energy found in the air outside the building envelope, turning it into warm water for the active ceiling system.

Underfloor Heating
Warm water is gently and quietly circulated throughout pipes encapsulated within the concrete slab floor and radiantly warms your entire home.

Powered by electricity, the Grant Aerona3 heat pump is using an entirely renewable energy which helps reduce the amount of harmful greenhouse gases being released into the atmosphere and, in so doing, lowers the carbon footprint of the household.

– Low noise level ensures quiet operation for the comfort of home owners and neighbours.
– A high level of performance even when its -10°C outside.
– Ultra energy efficient and compared to a gas-fired system saves the equivalent CO2 emissions reduced by a forest area of around 2,500m2.

Grant Aerona3 heat pumps can deliver over four times the amount of energy for every single unit of electricity used depending on the flow temperature and the climate conditions prevailing at the time. Homes utilising this type of heat generator will obviously have a lower dependency on fossil fuels, making them less susceptible to rising fuel costs.

DOLLARS AND SENSE

Costs will vary depending on perceived comfort levels, insulation levels, ambient temperature extremes, building design/construction and regional energy prices. Below shows the estimated installation and running costs for a new 200m2 home based on 0ºC outside / 20ºC inside temperature.

Appliance type System Type Heating Only Heating & Hot Water Winter Running Cost / Month Calculation
Heatpump Underfloor $25,000* $32,800** $290 0.28c/kWh x 16hrs/day
Natural Gas Underfloor $14,900 $20,300 $220 0.07c/kWh x 8hrs/day
LPG boiler Underfloor $14,900 $20,300 $560 0.18c/kWh x 8hrs/day
Diesel boiler Underfloor $19,100 $24,600 $380 0.12c/kWh x 8hrs/day
FREQUENTLY ASKED QUESTIONS
How much does underfloor heating cost to install?

New underfloor heating installation costs in NZ can depend on the appliance type, home design, and whether you purchase a heating only or heating and hot water system.

For high-quality systems you can trust, prices can start from $14,900 for a heating only gas boiler to $32,000+ for a heating and hot water heat pump underfloor heating system.

How much does underfloor heating cost to run in NZ?

Monthly winter prices can depend on your region’s temperature extremes, climate, home design, and regional energy prices. Underfloor heating with natural gas can cost around $220 per month, while an LPG boiler underfloor heating system may cost about $560 per month.

What floor types are suitable for underfloor heating?

Most flooring types in NZ are suitable for underfloor heating, but some are better than others. Concrete is ideal for heating and cooling, as are tiled and stone floors. Timber flooring and carpet may only be suitable for underfloor heating rather than cooling.

Do you need other types of heating, or is underfloor heating enough?

In most situations, underfloor heating should be enough to heat your home, however, it’s not unusual to have mixed systems with both underfloor and radiators or underfloor and active ceiling.

Is underfloor heating efficient?

Hydronic systems that give you control over your fuel type can be very efficient. You can choose the best fuel type based on your area, such as heat pump, LPG, natural gas, and diesel.
