RADIATOR HEATING
Warm water radiator central heating is the best way to heat both new and existing Kiwi homes. Not only does it deliver much higher levels of comfort, it responds the best to our changeable weather and busy lifestyles giving us exactly what we need when we want it. 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.
Advantages of radiator heating:
- Radiant heat with no forced air movement
- Radiators are totally quiet, unlike air conditioning units
- Quick response time (around 10 minutes to warm up)
- Variety of styles available to suite your unique decor
- Operates at safe temperatures, between 60°C and 75°C
- Can be turned off individually or as a system
RADIATOR CONTROLS
Radiators heat up and cool down quickly. They also have their own thermostat on each radiator that regulates the radiator according to the air temperature of that particular room to stop overheating (for example: when the sun comes into the room) or to turn off that particular room. This is called a thermostatic radiator valve (TRV) and is a good simple control.
There also needs to be a central controller for selecting times for the whole heating system to come on and go off automatically and to select what general air temperature to heat the house to. This control thermostat is often located in a hallway or neutral area (an area that isn’t easily affected by the drafts or solar gain).
Options are wall-mounted digital program thermostats to Smart Nest Wifi controllers. A system with one programmable thermostat is called a single control zone with slave thermostats on the radiators. This is the most common way to control radiator central heating and gives great control and convenience.
Controllers come with a 5-year warranty.
