- The E-Tech W is an electric, modulating boiler, optionally with complete domestic hot water supply
- The unit is available in 7 models with a nominal output of 8 to 36 kW and is standardly delivered as a wall-mounted version
- Particularly suitable for residential and small commercial applications, also as support for the heat pump to handle peak loads and as a backup
- Easy to install, ready for immediate use, and extremely low-maintenance
- The comfort of heating with hot water
- Completely silent operation
- Suitable for any heating circuit
- High-quality steel heat exchanger
- Heating elements made of high-quality stainless steel (Incoloy 800), highly resistant to high temperatures and corrosion
- Finished with a modern painted steel casing, equipped with a control panel
- Modulating output based on heating demand
Room Thermostat:
- The E-Tech W can (optionally) be controlled by a universal on/off 2-wire thermostat (capable of switching 230V).
- Here are some examples (other brands may also be used as long as they can switch 230V):
- Honeywell smart thermostat T6 (Lyric) Y6H810WF1005 on/off
- Honeywell room thermostat T4 H110 A1023 on/off clock thermostat 230V (wired)
- Honeywell room thermostat TH8200 G1004 Chronotherm Touch on/off clock thermostat 230V (wired)
- Honeywell room thermostat T6360 B1002 on/off 230V (wired)
Domestic Hot Water
The E-Tech W is optionally available with kits for providing domestic hot water. There are two solutions:
- Domestic kit in combination with plate heat exchanger* (part number 10800085) + Wiring Kit DHW (part number 257F1132).
This solution is recommended for required boiler output > 15 kW and normal hot water demand (maximum CW4 with an E-Tech W 28 tri). See performance below.
- Domestic kit in combination with an external boiler (part number A1002653) + Wiring Kit DHW (part number: 257F1132).
This solution is recommended for smaller boiler outputs or high hot water demand (multiple outlets simultaneously). Used in combination with a Smart or Comfort boiler (100 - 240 liters).
