Generally a diesel boiler, gas boiler or heat pump located in a convenient place, normally the laundry, garage or external.
Central heating is a method of whole-home heating in which warm water circulates through a closed network of pipes, carrying heat around the home. The heat source warms the water circulated through the pipes that lead to radiators or to the pipes laid in the floor for underfloor heating.
Gas boilers are the most popular appliance for warm water central heating worldwide. Many years of development have gone into the technology to make them super efficient, convenient and cost effective. They provide heat for radiator and underfloor systems equally well and can use either LPG or Natural Gas. This makes gas boilers a flexible option when determining which heat source is right for you.
Diesel boilers are compact, powerful, virtually silent, odourless and smokeless. They are the ideal heat source for warm water central heating systems. Particularly radiator systems.
Air-to-water heat pumps are among the most efficient heat sources available for warm water central heating. It is the same refrigeration technology that most Kiwi’s are used to with the air-to-air heat pumps that are so popular. Air-to-water heat pumps put the energy into the water that is used in the warm water central heating system rather than blowing air around the home.
Geothermal Heat Pump
A geothermal heat pump or ground source heat pump (GSHP) is a heat source for central heating and/or cooling systems that transfers heat to or from the ground.
Biomass or wood based fuel is important part of the energy industry for NZ as it is a renewable fuel based on living organisms like wood and waste, and is sustainable and helps reduce greenhouse gas emission. The typical biomass fuel products are logs, wood pellets and wood chips.
Wood pellet boilers are automatically operated and stocked so more convenient than log boilers for the end user. They do require a large hopper for the pellets to be fed into the boiler and these are often part of the appliance but sometimes have a secondary larger store connected.
Underfloor heating offers an effective, efficient heating medium that’s out of sight and makes no demands on wall space. Make cold and damp spots a thing of the past with underfloor heating, the most luxurious form of whole-home heating.
Radiators provide a responsive and flexible heating option for both new and existing homes. They heat up and cool down quickly, so are ideally suited to New Zealand’s changeable weather conditions and the typically busy lifestyles of New Zealanders.
Most systems have a wall-mounted thermostat. A thermostat monitors the room temperature and switches the heat source off when it’s warm enough, then turns it back on again if the room temperature drops.
Other central heating controls include timers that turn the boiler on or off at set times, programmers that allow you to adjust temperatures for different days of the week. Another popular option is a smart thermostat. These work remotely via your mobile or computer, so you can adjust the temperature in your home even when you’re not there.
