Sunamp Ltd. of Scotland has signed a memo of understanding with a Chinese manufacturer to develop a heat pump water heater for the residential market.
The new technology will combine heat pumps made by Jiangsu Gomon Renewable Energy Development Co. and Sunamp's UniQ heat batteries, which use a salt-based phase change material to store excess energy generated by solar PV systems. The stored energy is released on demand to provide heat and hot water.
The two companies signed the agreement last week at the ISH trade fair in Frankfurt. The agreement sets the terms for manufacturing and marketing the product in China and worldwide. Sunamp says product testing is already underway.
“Sunamp aims to displace as many water tanks as possible with UniQ heat batteries," said Maurizio Zaglio, Sunamp's international business development manager. "The fact that one of the largest manufacturers of water tanks in the world has decided to develop a new product with us is an important milestone for Sunamp."
In a presentation at ISH, Zaglio put it more plainly: "We are not here to complement hot water tanks - we are here to replace them!"
The deal is Sunamp's second with a major Chinese manufacturer in the past four months. In November, the company signed an agreement with Trina Solar to develop an integrated solution combining Sunamp heat batteries now made in Scotland with heat pumps manufactured at Trina's new factory in Changzhou, China.
