Condition - Like new, not powered on

A tank heater keeps 200 litres hot all night for a shower you take at seven in the morning. The ThermoMate 27kW tankless water heater makes hot water only while the tap is open, delivers up to 5.27 GPM, and frees the floor space the tank was standing on. Open-box, at a fraction of new.

💡 Why You’ll Love It:

✅ Hot Water in About 3 Seconds: On-demand heating with no tank to wait on or run out of
✅ 5.27 GPM at a 35°F Rise: Enough for a shower and a sink at the same time in most homes
✅ Self-Modulating Power: Draws only what the flow needs, up to about 60% less energy than a tank
✅ Digital Control 80-140°F: Set the temperature to the degree and it holds there
✅ Isolated Heating Element: Less scale contact means less descaling and longer element life
✅ Compact Wall Mount: Roughly 43 x 33 cm on the wall instead of a tank in the corner
✅ ETL Certified with Overheat Protection: Safety cutout built into the control board

📋 What “Like New” Means Here:
• Packaging: original box, opened, some shelf wear
• Cosmetics: as shown in the photos — please review them before ordering
• Accessories: complete as received — heater unit with mounting hardware and manual
• Function: not powered on — sold as untested, since bench testing needs three 40A double-pole circuits

🧼 Care & Use:
• This unit needs 3 x double-pole 40A breakers and 3 x 8AWG runs — have an electrician confirm the panel first
• Install a service valve kit so the unit can be flushed without dropping it off the wall
• Flush with descaling solution once a year on hard water
• Set the temperature to 120°F for household use; higher settings scale faster and scald

🔗 Perfect for: Home renovations, cottages and basement bathrooms where a tank will not fit.
