Running cost of any heating system depends a lot on several factors. The Energy Saving Trust recommends that one should be looking more at life time cost than just what it costs to heat a given space per time. Whilst the lifetime cost of our heaters, considering a 15 year guarantee and the fact that the heaters require no maintenance at all, is extremely attractive and even lower than a gas boiler central heating system, many an enquirer have often asked us to give a snapshot of what it costs to run our systems compared to Economy 7 Night Storage Heaters. Here is an example of our calculation:

According to the Department of Energy and Climate Change (DECC) website, the average energy consumption cost per household in the UK is about £1300.

60% of this covers gas usage (£780) and the rest of the 40%  (£520) covers electricity. The DECC's statistics assume that any average household will have mains gas and therefore uses electricity only for lighting and home appliances but not heating. So £780 for home heating using gas is clearly higher than what it'll cost to use Suka heaters.

Function and method of operation

The Sueka radiators from Germany work in a similar manner to a normal central heating system. The main differences lie in the fact that normally in a central heating system, a boiler is required to heat water, which is then pumped around the system so as to heat the radiators, whereas with Sueka radiators, the radiator ribs are heated by a system of internal specialist energy cells, each with its own embedded heating element. The Sueka radiator ribs ensure that a very large surface area is available to be evenly heated and this heat is then radiated out into the room in an intensive and comfortable manner. In addition, the chimney effect, caused by the ribbed design, also produces convected heat so as to ensure an optimal mixture of convected and radiant heat, which, controlled by an efficient thermostatic control, together produce the most effective, comfortable and economic method of heating the room.

The secret to the Süka heating radiator is its intelligent use of energy, ensuring plenty of heat is available right through the day, while keeping running costs low.

15 minutes of electricity to provide 60 minutes of warmth.

Radiant heat: The heating system works by imitating the sun’s radiant warmth and relies on the best of all heat: RADIANT HEAT. Once the heat is absorbed into the radiator system, it is then radiated out in an intensive and comfortable manner throughout the room. In addition to the healthy emission of radiant heat from the side panels, a chimney effect caused by the rugged and precision design of the flutes surrounding the core of the heater, allow for a low level of convective heat which combines with the radiant heat to ensure an optimal ambient temperature in the room.

Night storage heaters, as their name suggests, give out their heat overnight, but because of their necessity to retain heat for a long period many kilowatts are used to produce that heat.

The advantages of night storage heaters are that they are charged up overnight at a cheaper rate of electricity; also, they give out their heat over a long period albeit a waning one.

Their biggest disadvantage however, is that they are mostly uncontrollable. For instance, should they be operative during the night because of the previous evening's chilliness and then come the following morning and it's a gloriously sunny day, they will still emit their heat as normal because they can do nothing else. Also with Economy 7 night rates having risen dramatically in relation to 'normal' tariff rates, storage heating is not as an attractive proposition as it was even a couple of years ago.

Approved Document L2A (ADL2A) quotes relevant kgCO₂ per kWh emission factor on Grid supplied electricity; at 0.422 kgCO₂ /kWh, we need to save all the generated electricity we can. 

Carbon Dioxide effect of Süka Heaters

Here’s how Suka heaters’ impact on CO₂ emission is compared to Night Storage Heaters.

For a well insulated 3 bedroom house of double glazing, Sueka will put in a total of 7.5kW heaters for an ambient temperature of 20ºC. At full capacity, Suka heaters churn out 32ºC of heat. But a normal healthy room temperature should be an average 20ºC at +/-5ºC outside in winter. Sueka radiators therefore need work only on average at 60% capacity to maintain that warmth.

Impact on environment as a result of its use of grid generated power:

= (7.5kW heater) x (24hrs in a day) x (0.25 being quarter of actual usage time) x (60% capacity usage) x (220 days in a year of winter) =

 = 5,940kwh per annum

Therefore,  0.422 kgCO₂ /kWh x 5,940kwh per annum  = 2.507 tons of CO₂

Thus effect of the homeowner on the environment through Suka heaters’ consumption of Grid generated power is only 2.5 tons of CO₂ per annum.

Now, consider a night storage heater below even at Economy 7 so-called cheap tariff:

Economy 7 Night Storage Heater

The same house will require about 14kW of Night Storage Heaters or a combination with panel heaters. An additional boost with 4.1 or more kWh in the evening may also be required.

Impact on environment as a result of its use of grid generated power:

= (14kW heater) x (7hrs Economy 7 usage) + (3.4kW x 2hrs boost in the evening) x (220 days in a year of winter) =

 = 23,056kWh per annum

Therefore,  0.422 kgCO₂ /kWh x 23,056kWh per annum  = 9.730 tons of CO₂

Thus effect of the homeowner on the environment through Night Storage heaters’ consumption of Grid generated power is only 9.7 tons of CO₂ per annum.

Important Note

Given that the rugged German construction seals Suka’s heating elements completely from surface atmosphere, there’s no further CO₂ produced at the point of use.

This is not the case with Night Storage Heaters or convector panel heaters which have heating elements exposed to surface atmosphere and thus burn any dust particles it comes into contact with. Some heaters have even out-moded elements that can be seen glowing red hot when switched on. So at the point of use, Night Storage Heaters burn oxygen and produce CO₂ emission in addition to what they cause power stations to produce above. Even if the element is tungsten, its exposure to surface atmosphere is still unhealthy for the environment due to constant power intake burning of surface particles.

Heating with electricity is a good choice because electricity offers considerable advantages:

• Low level of investment
• Simple effective controllability
• Guarantee of supply
• No maintenance
• Overall lifetime costs (Initial investment, maintenance, running costs) lower than some other systems
• Clean and comfortable
• Easy to install - affixed to wall, or on legs or on castors
• Easily removable when decorating

When moving house, just take the heaters with you
