The Comparison with other heaters eg. night storage heaters

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.

Now, for those who don't have gas, consider the cost of equivalent night storage heaters in the above property at Economy 7 so-called cheap tariff:

Expected running cost of night storage heaters during a 24 hour/day use at 16.73pence per kilowatt hour (peak time of 17hrs) and 5.49p per kilowatt hour (off-peak of 7hrs) on Economy 7 Tariff

*Running cost = kWh used x electricity tariff rate x consumption in every 60 minutes x 50% running capacity assuming night store heaters are controllable

Stove heating	Convector heating	Oil/Liquid Gas Central heating

Much loss of heat Large differences of temperature between floor and ceiling Dry air which can cause problems for eyes and sinuses	Uneven distribution of heat Too much movement of dust Often noisy Draughty	Large amount of space required for tank High cost of installation

Sueka heating system
	Even distribution of healthy warmth from floor to ceiling NO draughts NO dust swirling in the air NO loss of energy NO extra space required for boilers and/or tanks Simple Installation NO Maintenance
