- 2 year parts and labour warranty
- All the Logic HIUs incorporate a spacer piece which can be easily removed and a heat meter fitted inside the unit. This allows the energy used by each individual apartment to be recorded and charged accordingly
- Twin plate design hydraulically separates both domestic and space heating from the central primary supply
- Pump bypass protection, in case of complete radiator TRV shutdown
- Compact and lightweight
- Fully insulated EPP front cover
- Convertible to underfloor heating
- Ability to pre-heating of the DHW exchanger
Logic Heat Interface Units (HIU) Indirect - 50 Indirect
The Ideal Heat Interface Units (HIU) are heat energy transfer units, designed for use in conjunction with centralised boilers, district heating or central energy systems. The function is to efficiently transfer heat from
the plant room to the individual dwellings central heating (CH) and domestic hot water (DHW) systems.
The Logic Indirect HIUs are the latest 'intelligent’ range of HIU from Ideal. The Logic HIU is the complete solution for instantaneous hot water production and space heating control. The indirect wall mounted HIU,
providing instantaneous priority direct hot water (DHW) and modulated central heating (CH). This can be converted to under floor heating including inbuilt safety thermostat capability.
