New tech for historic housing
Southern Housing Group wanted to include solar thermal as part of an upgrade to Lisgar Terrace estate. Oventrop UK limited were employed by H&V Service Plan to deliver solar thermal domestic hot water systems to 7 newly created apartments on phase 2 of the development.
The remit of OVUK was the design, supply and installation of suitable systems.
Each of the 7 systems uses two OKF CS22 high efficiency solar thermal collectors mounted on aluminium ‘A-Frame’ mounting systems. The systems were all connected using highly insulated, stainless steel pipe installed in single lengths to avoid joints and lower any risk of leaks.
The system fluid (Tyfocor LS Polyproline Glycol) is circulated via an Oventrop Regusol pump set and controlled using an Oventrop Regtronic Controller with built in over heat protection both of which are ERP compliant.
The systems heats 200L of water to 60oC on bright days. The water is stored in a high efficiency stainless steel unvented hot water cylinder located in the services cupboard of each apartment. On average each tenant can expect to save circa 40% on their costs for heating their domestic hot water as well as saving around 500kg of CO2 per system and doing their bit for the environment.
