Flued Gas Fire
Flued Gas Fires
If you want lots of heat and real flames, then a flame-effect gas fire could be an option. Or you can choose a floor mounted energy saver model. Running costs are higher than for a wood burner or heat pump – but you can’t toast yourself in front of a heat pump or just press a button to light a wood burner. Natural gas and LPG are clean-burning for pollutants. Make sure if you use gas heating that it is flued.
|Pros||Ease of use||Cons||Cost - flued gas is possibly more expensive than an equivalent sized heat pump and certainly more expensive than a woodburner.|
|Quickly warms a room and maintains a comfortable temperature||If you have mains gas you need to pay a monthly connection fee, even if you only use your gas heater in the colder months|
|Some gas heaters need electricity to work so will not work in a power cut|
|Burns fossil fuel|
Wood burners are a common form of heating in New Zealand. Ministry for the Environment has an approved list of wood burner’s that are more efficient and produce less air pollution than wood burners in the past. Regardless of the wood burner’s age, how the wood burner is operated affects whether it is a source of clean heat. Fuel used must be dry, seasoned wood otherwise a smoky fire producing high levels of pollution is the result.
ULEBs or Ultra Low Emission Burners are a new kind of wood burner that has two combustion chambers, compared to the one of a conventional wood fire. Light your fire in the top chamber with kindling and a small amount of wood. No wood goes into the lower chamber. This chamber is designed to bolster combustion by re-combusting gases (typically smoke), expelled during primary combustion. This secondary combustion creates maximum heat in conjunction with very low emissions.
|Pros||Atmosphere and ambience||Cons||If not used properly woodburners will produce less heat and will cause more smoke which is detrimental to our air quality|
Heating bills not affected by rising electricity prices
|If you don't buy your wood supply, then you need time to source and split your wood|
|You can still heat your house if there's a power cut||Time and energy required to light fires, and time taken to produce heat required to warm your house|
|Burning wood is carbon-neutral because it's a renewable resource, but burning it cleanly is the key to making it environmentally friendly too||Have to ensure you have space for your firewood to be stacked correctly and protected to keep it dry|
Heat pumps are a great way to heat your home and do not produce any of the harmful PM10 particulates in the air. They provide convenient, efficient, thermostatically-controlled heating that can be pre-set at different times of the day to turn on and off. The simplest versions are designed for a single room; the most complex, for a whole house. It takes 20 to 40 minutes to bring a room up to temperature, after which the level will be maintained within one or two degrees.
A heat pump works by extracting heat from the air outside your house and bringing it indoors. It’s like a refrigerator in reverse. Some areas of Rotorua have high concentrations of hydrogen sulphide (H2S). This gas is very corrosive and can cause problems with metal corrosion and electronics, all of which are incorporated within heat pumps. Before choosing a heat pump check with your supplier how they propose to treat the heat pump to ensure it can withstand Rotorua conditions and confirm any effects the Rotorua conditions may have on manufacturers’ warranties.
|Pros||Warm, dry and comfortable||Cons||
Can be noisy. Fans run both the interior and exterior units when switched on. The fan in the inside unit should produce little more than a low hum in low-speed mode, but the compressor plus the fan in the outside unit can be quite noisy
|Can quickly bring a room up to temperature and then maintain it||Heat performance can reduce in low temperatures. Extracting heat from outdoor air gets more difficult as the temperature drops.|
|No gas charge||Circulating air can cause draughts. Check with your installer about the best place to position your unit to minimise any draughts|
|A reverse-cycle heat pump is the only type of heating system that can both heat and cool a room|
|If you switch a heap pump into cooling mode, it will also dehumidify the air in your house|
|Many heat pumps incorporate a washable filter unit that removes dust and particles from the air|
