Gas Central Heating Wellington – Ducted Warm Air or Radiators
Warm air heating has been around a long time. The Romans used to heat their floors by lighting a fire at one end of the building and putting a flue at the other end, and allowing the hot air to run under the floor heating the floor. Central heating systems have changed now. We install ducting under the floor, with different materials, and there is a thermostat now.
We offer gas central heating Wellington wide. We maintain most brands and recommend brands that have good service histories and which have low running costs. At Southern, we offer efficient and cost-effective gas central heating services, including installation and repairs in Lower Hutt, Petone and Wellington. Gas central heating systems play a major role in your home, providing warmth and comfort when it’s cold outside. But they can also be an expensive investment, so you need to make sure they are installed properly by an experienced team.
Warm Air Ducted Central Heating
Hot water Boiler Radiator Central Heating
Hot water boiler radiator central heating systems are a highly effective and popular method for providing warmth and comfort to homes and buildings. These systems consist of a central boiler that heats water and circulates it through a network of pipes to radiators located in various rooms. The radiators, typically made of cast iron or steel, release heat into the surrounding space, warming it up efficiently. The hot water is then returned to the boiler to be reheated and circulated again, creating a continuous cycle of warmth throughout the building. This type of central heating offers several advantages, including consistent and controllable heat distribution, energy efficiency, and the ability to zone different areas for customized comfort. Additionally, boiler-based systems can often be integrated with other heating sources, such as solar panels or heat pumps, further enhancing their sustainability and reducing reliance on fossil fuels. Overall, hot water boiler radiator central heating is a reliable and effective solution for achieving optimal indoor comfort in residential and commercial settings.
What are the Types of Central Heating?
How Does Central Heating Work?
The occupant selects the desired temperature and the times the central heating will turn on usually in the mornings before getting up. The central heating can be turned off if required or let it go on if the temperature drops below that desired temperature. Central heating is a good choice for unpredictable weather conditions like in Wellington. Ducted gas heating is well known for most buildings.
Advantages and Disadvantages of Central Heating
Central heating usually heats the entire building. For warm air, there are systems to close off areas such as Zone 1, Zone 2 and so on. These zones often refer to rooms of the house. With water radiators you can close off each room and put rooms on thermostats. Spot heating is a single gas fire or electric heating that heats that area or room.
Buildings that have low insulation like no double glazing, there is high heat loss in central heating. Spot heating may be better where the heater is a radiant type.
Most old homes are not insulated because the insulation was not required as a Building code requirement in past years. Central heating is a good option if you want to control the heating level or temperature in your entire home. It is also good if you spend most of your time at home. You can set a time and temperature using a thermostat for central heating. Even though central heating is a good heating system, it can cost a lot more than you think.

Wall Radiators Central Heating
This type of central heating requires the radiators to fit on the walls and piping run back to a boiler. The radiators are usually fitted on an outside wall under a window. Each radiator can have a thermostat and a shut-off valve. Wall radiators are designed keeping in mind the flexible heating options for homes. It is a typical preference for most people in New Zealand due to the changeable weather conditions. Radiators are good at reducing health hazards in the house. They are safe, silent and responsive. You don’t have to worry about children or pets around radiators.
Alternatives to Central Heating
Rinnai‘s new powerful Rinnai 1005 Energy Saver has an 8kw output for large rooms or you could put a heat transfer system to send heat to other rooms. Up to two other rooms in the case of a Rinnai 1004.

Customer:
That’s very helpful. We are looking into electric radiators as an alternative option that would give us more flexibility re heating different parts of the house.
Southern Plumbing:
Ok the difference is 6 Star gas warm air furnace operates at about 14 cents per kw. Hot water radiators (gas) are similar. Electric Radiators are what your power supplier charges for electricity 23 cents is most common. In big rooms its gets hard as you often need about 3-4 kilowatts in a lounge, or hall and electricity struggles to do that usually only 2kw unless you buy something special. If you had them all on at once it would be a 37Amp draw on a power cable with the oven also at 30 Amps its more than the house can handle as the max is 60Amps.
This is why heat pumps are so popular at about 5-9 amps but only heating one room. or 12 Amps (larger model) for two rooms. There is Heat Pump central heating but that is even more expensive and has larger ducts but with a lower running cost than gas. at about 8 -12 cents a kw. depending on the in coming air temp.
Gas will not be running out in our lifetimes as it will be Hydrogen and or Biogas.
Summary:
The reason gas is used is due to cheaper running costs than electric. Heat pump can be cheaper to run if using heat pumps just doing one area. But to control bedroom you need Heat pump central heating then the install price jumps up.
