Are they efficient?

An electric radiator from LVI is basically 100% efficient. The power used is all converted to heat with the exception of a very small amount for the electronic control circuit. There is no fan, pump, or boiler to use up extra power.

How much to run?

The cost to run is calculated as follows:

Power is metered in KWH, (kilowatt hours)

An average charge to the household is 21cents per KWH. Currently with discounts you pay about 19cents to 21cents per KWH. I will work this out on 21cents/KWH

A 1000 watt radiator operating on maximum temperature for 1 hour will cost 21cents to operate. However the LVI radiator uses a “flatline” thermostat that incorporates very fast switching to maintain a constant room temperature. When sized correctly, the thermostat will turn on and off at a 50% ratio meaning power is on for 50% of the time across the operating hour. This reduces the electricity cost to approx 11cents per hour to run for a 1000watt radiator.

Wattage              Current                 Cents/Hr

250watt                  1.0A                          3 cents

500watt                  2.1A                           7 cents

750watt                 3A                               9 cents

1000watt               4.2A                           11 cents

1250watt               5A                               14 cents

1500watt               6A                              .17 cents

2000watt              8A                            22 cents

Are they easy to Install?

Two brackets screwed to the wall and the radiator clips into place. Plug into a normal power point and turn on. Average time to install is 20mins.

LVI radiators now come with a wall connection box. This box is mounted behind the radiator. The special plug from the radiator controls will plug into this box. When connecting to power, we can “hard wire” by bring the power cable direct into this box. Or we can connect a 240vplug with flexible cable to allow it to be ‘plugged in”.

Can they be wired as a central system?

In a new house it is easy to wire the heater power points back to a central control system within the switchboard. However, most people are now looking to be energy efficient and not heat rooms they are not using. Therefore the individual control of each room heater is what people are looking for now. Talk to LVI if you want control options.

What maintenance is required?

There is basically no maintenance required for your LVI radiator.

Further, as they do not circulate dust, the cleaning required is minimal.

Are they repairable? 

If there is a problem with the electrical circuit on your LVI radiator, it can be easily repaired by your LVI supplier. Spare controllers and elements are available if required.

Are they noisy?

LVI radiators are filled with oil to disperse the heat across the panel. The design of the radiator means there is no expansion noise or thermostat noise. They are fully silent during their operation.

Do they circulate dust?

A true radiator does not rely on air movement and therefore dust is not circulated with an LVI radiator.

Do they smell?

The LVI radiator runs on a low temperature principle and does not exceed 60 deg c. The element is completely immersed in the oil and does not contact the air. Therefore the element can not burn or ionise dust. This means there is no smell emitted from the radiator.

Is there a difference in running costs between the LVI granite range and the steel panels?

LVI does not publish a cost to run difference. Both operate as true radiators, with no external fans to blow their heat. they both operate with a heat bank effect to minimise temperture change. The steel panel uses the energy stored in the oil and the granite range uses the density of the granite stone to retain the heat and maintain an even temperature distribution into the room.

Can they be painted?

Yes they can. Because of the low surface temperature, if you wish to match the colour to your room then this is possible.

Do they come with a timer? 

No they do not.

In their country of manufacture, Sweden, the radiators are left turned on all the time. They rely on the accurate thermostat to control the room temperature.  If a timer is required, then a simple plug in powerpoint timer is the cheapest and easiest option.

What are the controls on the thermostat housing?

Advanced thermostat with precise regulation.

Several temperature reduction options.

  • Adjustable maximum surface temperature of 90°C (normal) and 75 or 60°C (reduced). The 75 and 60°C modes reduce the output of the radiator to 70 and 55% for a single and 90 and 80% for a double panel.
  • Sequential temperature control of the front and rear panel.
  • Window open function.
  • Lockable thermostat unit.
  • Thermostat guard made from flame retardant and UV resistant ABS-PC V0.
  • The temperature reduction can be activated manually or with a separate control wire connected to a central timer.
  • The radiator is supplied with a cable with a “plug-in contact” for connecting the radiator and the enclosed wall outlet box.
  • Can be controlled from other radiators or control other radiators in a master-slave configuration.


What other safety features are Installed?

  1. There is an overtemperature cutout that will operate if the radiator is covered and excessive heat builds up. This will automatically reset when the problem is removed.
  2. If for some reason the temperature exceeds a preset limit, the element has an over temperature fuse that will open. A new element is required in this instance, but this is designed to prevent fires.
