It all depends on which heaters you require. Süka heaters cover a wide power spectrum from 0.4 kW output to 2.5 kW output. A small heater can cost less than £500 and a whole set for a house costs between £1,600 – £3,500. The investment cost is comparable and usually cheaper than a normal central heating system using gas or oil. With Süka there are no maintenance and service contracts required, no repairs and no redecorating to worry about.
So comparing lifetime costs: Capital Investment + Minimum Maintenance Costs + Running Costs, Süka works out the least expensive and has the least amount of disturbance with the installation. Remember, when comparing costs with other systems; make sure you always take into account all future costs. Running costs for gas and oil has increased a lot more than costs for electricity and are likely to continue to do so for years to come.
