In indirect heating type, water does not circulate. An anti-freeze agent is used in the copper tubing system. When heated up, this agent will in turn heat the water in the storage tank. Glycol, the common and usual anti-freeze agent, will diminish gradually and thus needs and costs to be replenished regularly. This system works something like the element that boils the water in our kettle. This system is more expensive but is very good and suitable for places that have winters or where nights are freezing cold.
Direct heating solar water heater has two versions, vacuum and pressurised types. Cherry solar water heater belongs to the pressurised direct heating type. Most of Malaysian solar water heater belongs to this later category. This is the best solar water Heater system because of its simplicity, durability, reliability, versatility and cost. On the contrary, vacuum direct heating type is complex and less versatile, therefore, it costs more to build, install and operate.
Cherry solar water heaters are built to last. Storage tank, available in 35 or 62 gallon size, is made of 1.5 mm thick #304 stainless steel from Japan. The storage tank is insulated with 4 inch thick high density polyurethane (for maximum heat retention) with stucco aluminium as external cover. Each heating panel consists of 10 tubes of ½ inch diameter copper tubing insulated with glass fibre encased in aluminium with heat absorbing black colour material coating and low-iron glass panel cover. Standard unit comes with pressure relief valve and booster port while the electric booster element is optional. Cherry Solar Water Heater does not require any sacrificial anode for protection against corrosion. (The use of anode needs regular replacement, which means additional running cost)
