Description
Electronically controlled twin plate hydraulic heat interface unit (HIU), designed to provide instantaneous hot water and heating to the dwelling.
Features and benefits:
- Domestic hot water (DHW) output up to 60 kW.
- Heating (HTG) output up to 10 kW.
- DHW and HTG controlled by pressure independent control valves (PICVs).
- Fully insulated expanded polypropylene (EPP) casing.
- Innovative cooling area to reduce ambient temperatures to extend component life.
- Heat meter and pressure gauge visible with casing installed.
- Insulated case constructed in three sections to improve access for maintenance and commissioning.
- Standing heat loss of: 60 or 70°C: 31 W.
- vTherm°e achieved the lowest Volume-Weighted Average Return Temperatures (VWART) at a primary flow temperature of 60°C of any BESA tested HIU: 70°C: 27.9°C (VWART). 60°C: 29°C (VWART).
- In periods with no DHW or heating demand, the HIUs standing heat loss shall be a maximum of 32 W.
- WRAS approved.
Material:
- Pipes, fittings, valves (primary and heating): 1.4301 (AISI 304), CW617N, CW614N, CW602N, CW625N, GG15.
- Pipes, fittings, valves (domestic hot water): 1.4404 (AISI 316L), CW617N, CW617N, CW602N.
- Heat exchanger: 1.4404 (AISI 316L) Cu Brazing.
- Insulation: Expanded polypropylene (EPP).
Some additional materials are used by component manufacturers such as valves and pumps. These are in small components within the assembly.
