Product Introduction

Wombat flat plate solar water heater is a thermosiphon solar water heater that incorporates a high efficiency heat pipe flat plate collector and mains pressure stainless steel storage tank. An electric element provides backup heating to ensure hot water all year round.

In high solar radiation areas, Wombat solar water heaters can be the sole energy source for hot water supply. In cooler climates Wombat systems can provide pre-heated hot water which saves traditional electric or gas energy costs. The tank has an optional electrical heating element for boosting. 

Basic Operation

Flat plate absorbers absorb sunlight and convert it to usable heat, which is transferred to the heat pipes welded to the underside of the solar absorber sheet. The heat pipes contains a small amount liquid which forms steam when heated, rapidly transferring the heat up to the header pipe which is connected to the storage tank. Water in the storage tank gradually circulates through the header pipe heating up the tank throughout the day.
