Operating Costs

operating costs1The Government’s report on the Energy Review, released on 11 July 2006, clearly supports electricity as the fuel of the future, with secure, low-cost supplies meaning that the UK will be increasingly self-sufficient for energy in years to come.

The UK is already a net importer of gas and the level is expected to rise to 75% within the next 8 years, (in 2013 it had already reached 62.5%). North Sea gas is expected to be used up within 20 years and the UK will then be totally reliant upon imports, (shale gas production being only theoretically possible with many activists aligned against the industry).

The cost of all fuels has risen steeply recently but oil and gas prices have outstripped the cost of electricty. The era of low cost fuel – if it ever existed – has past and we have to conserve precious resources for the good of all.

Radiant heating systems are very efficient because ideal personal heat comfort can be achieved with ambient air temperatures of only 18 deg C to 19 deg C resulting in significant energy savings.

For every 1 deg C that your thermostat is turned down, you could save as much as 10% on your energy consumption. Turning your thermostat setting down from 24 deg C to 20 deg C produces a significant saving without sacrificing personal heat comfort.

Radiators vs. Radiant Floor Heating

Radiators require high water temperatures and most of the heat delivered by traditional radiators occurs via convection because their surface area is relatively small. Air passes over and through the radiators creating convective warm air currents. Radiators stend to create uneven pools of warmth with the warm air currents affecting the ideal convective loss of the body.

The adjacent graphs show how inefficient and ineffective radiators are compared to radiant floor heating which represents the ideal heating curve and the pink area represents wasted energy / heat.

Energy consumption is determined by the thermostat being programmed for optimal economic operation of the heating system – NOT by the W/sq m of the heating mat.

The fully programmable Vysa-Therm 3000 and Touch Screen thermostats have been developed to specifically exploit the energy saving potential from radiant floor or ceiling heating on a room by room basis with optimal comfort. We therefore recommend that you use it to control your heating system so that you can have comfortable temperatures when you are at home and energy savings when you are asleep at night or out during the day-time.

Based on a cost of £0.07 per KW/h, a room fitted with a 5.0 sq m heating mat rated at 150W/sq m would typically cost about £4 to £5 a month to run. Fitting Vysa-Pron thermal insulation would reduce operating costs and improve heat-up times.
