Simple, just contact us for a local consultant to visit you with a demonstration heater. This is completely FREE and without obligation. FEEL and EXPERIENCE for yourself how effective the system works and then ask the consultant to carry out the FREE survey. After that he/she can calculate YOUR heating requirements, work out the best package of heaters for you, calculate the running costs and give you the best price. Only when you have ALL of the valid information, can you make a valid decision as to whether Suka is for you! NO COST - NO OBLIGATION - NO PRESSURE - NO HASSLE
