The Sudarshan Saur 150 LPD ETC PR Solar Water Heater is a pressurized evacuated-tube system using heat-pipe technology, built for homes with a booster pump. It runs 17 heat-pipe tubes into a 150 litre tank, handles water hardness up to 1000 ppm, and is designed for a 15-year service life with a 5-year guarantee.
What heat-pipe technology means, and why it matters. Unlike a standard ETC where water flows directly through the glass tubes, this system uses sealed oxygen-free copper heat pipes inside each tube. The heat pipe absorbs solar heat and transfers it to the water in the tank through a condenser, while the water itself never enters the tubes. The practical advantages are real: because water does not sit in the tubes, there is no scaling inside them, the system resists freezing damage, and if a tube breaks the system keeps working rather than draining. For hard-water areas and reliability, heat-pipe is a genuine step up in engineering over direct-flow ETC.
Pressurized for booster-pump homes. This is a PR (pressurized) system, built for homes running a booster pump. It delivers hot water at the pressure of your plumbing, so your shower stays strong. If your terrace has a booster pump, this is the configuration you need tell our team to confirm before ordering.
Build quality in the tubes. The heat pipes are TU1 oxygen-free copper throughout, with 58mm outer / 47mm inner tubes at 1800mm length, two-piece aluminium fins, and pure silicon seals a specification built for durability and efficient heat transfer. The unit handles water hardness up to 1000 ppm.
Before you order: your terrace needs at least 9 feet by 6 feet of clear, unshaded space. Confirm you have a booster pump if your system runs on gravity, a non-pressurized model is the correct choice, and Sudarshan's glass-lined non-pressurized 150 LPD carries a longer 20-year tank guarantee if durability is your priority.
The price includes transportation to your house, lifting to the terrace, and installation. You arrange the plumbing connection.
