• Building Regs - Meeting Hot Water Thermal Efficiency Of Part L

20 June 2019

Now available is the Rinnai HDC 1200i continuous flow hot water unit with the capacity to deliver in excess of 1500 litres of temperature accurate hot water per hour.

This level of performance means the Rinnai 1200i is more than capable of meeting and exceeding the hot water demands of many applications.   

Units can also be combined as into a single, easy to handle module incorporating cascade frames and common flue.

Both the HDC 1200 internal and external models turn in an energy performance of 107% net efficiency. Meanwhile when it comes to modulation, the system's internal analytical system can modulate the burner from 54kw to 2.4kw.

The Rinnai HDC 1200i is engineered for minimal energy wastage and maximum energy performance.

It is worth remembering that Part L of the Building Regulations 2013 has set minimum thermal efficiency levels of 90% for natural and 92% for LPG, consequently outlawing non-condensing gas fired water heaters for use in new build projects.
