Night Storage Heaters Running Costs

Why are you looking at night storage heaters?

German electric radiators from West Country Heating can slash your heating bills and never leave you cold again.

Night storage heaters running costs depend on numerous factors: your electricity tariff, the thermostat temperature setting, how your heating system is used (on/off or continuous) and the heat loss of the rooms. With all heating systems, the thermostat affects the running costs, however, it has been proven that German electric radiators beat Economy 7 storage heaters when it comes to running costs.

German Electric Radiators Vs. Night Storage Heaters Running Costs

A study was conducted over 12-months to measure the total electrical usage of power, heat and light in a 1960’s two-bedroom detached bungalow with cavity wall insulation, loft insulation and double-glazing. The property also had no gas, solid-fuel or any other kind of heating.

The study revealed that over the course of a year, the homeowner saved over 34% on heating costs when she used German electric radiators. It also demonstrated that the bungalow felt warmer and offered a more efficient heating system. The study showed that the homeowner saved £199.55p per year making German electric radiators a solid long-term investment option in comparison to traditional night storage heaters. German electric radiators also reduced the householder’s carbon emission release by 66%.

German Electric Radiators Cheaper Than Night Storage Heaters

To compare the German electric radiators heating costs to the night storage heaters running costs, the electric radiator uses 4,205 units of flat-rate electricity used for heating, creating 1,837kg CO2, whereas the night storage heating uses 12,740 units of off-peaking electricity used for heating, which creates 5,555kg CO2. Night storage heaters running costs equals £700.70p in comparison to our electric radiators running costs of £501.15p, making it a cheaper and more efficient alternative as it offers up to 33% cost saving and a 66% carbon saving.

If, for example, the average current electricity cost is 11p (per unit) per kw, this would mean that a 1kw radiator would cost 11p per hour to run if it was working at full power. If the radiator thermostat is set to 20 degrees, once the room temperature reaches that, the thermostat would turn the power off to the radiator. The thermostat would ensure that the heat emitted would be enough heat to counteract the heat loss of the room and keep the room at the desired temperature.

However, if the room has a heat loss of 200 watts per hour, the 1kw radiator would produce 200 watts of heat in that time and this means that the radiator would operate intermittently for 12 minutes of each hour.This means that it would cost 2.2p per hour to use the electric heaters based on UK tariff costs of 11p per hour. If a 1kw radiator was placed in a room that had less insulation, more outside walls, bigger windows and single glazing, it would have to counteract a bigger heat loss by emitting more heat per hour and as a result, it would be more costly to run. E.g. If the room has a heat loss of 800 watts per hour, the radiator would have to produce that amount of heat to counteract the heat loss and maintain a steady temperature. The radiator would operate for 48 minutes intermittently of each hour, which would make an electric heater’s UK tariff of 11p actually cost 8.8p.

More energy is used to heat a room to temperature than to maintain it at a steady temperature and on/off usage patterns end up being more costly than maintaining a constant temperature, or using ‘set back’ or ‘economy’ settings.

According to the Carbon Trust, your heating cost will rise by 8% for every 1 degree the thermostat setting is increased above 19 degrees. West Country Heating has a special temperature control system that provides the ability to program each radiator to the desired temperature, at the required time, so you will not be wasting any energy.


Free Home Survey

We carry out a free home survey so you can see our products at first hand.

Here we will survey the volume of each room and asses the build and quality of insulation. We will take into account the exposure, outside walls and areas of windows. Once we have this information, we can calculate the correct size and kilowatt rating of each appliance required. We also check the capacity of your fuse board and assess any new wiring which may be required.

All you need to do is sit and relax whilst we do all the work.
