ECP Hydronic Tank 15litre HotBox
The ECP Hydronic Tank 15litre HotBox is a 15 litre stainless steel glycol tank with a multi plate heat exchanger for hydronic hot water and heating systems.
This unit is fabricated in stainless steel and designed for efficient heat transfer and conversion of cold to hot water using a closed glycol circuit. It is fitted with a standard automotive pressure cap and is compatible with many diesel water heaters via the built-in mounting points.
The tank is filled with a 50/50 mix of green glycol and demineralised water. Maximum fill level is 10 mm from the top of the tank, or 40 mm from the top of the fill point. Additional outlets are provided for expanding system capacity and for adding electric heating elements and air heating hardware. An insulating cover is available, and the unit is approved for WaterMark applications.

Why a 15 Litre Hydronic Hot Water Tank ?
The 15 Litre Hydronic Hot Water Tank is designed for liquid heater systems where a 15 litre capacity balances heat-up time with available hot water, reducing rapid cycling compared with smaller tanks.
Reasoning
- Smaller tanks heat up faster but provide less hot water and can cause the liquid heater to cycle more often
- Larger tanks hold more water but take longer to reheat after hot water is used
- 15 litre hydronic tank sizing reduces frequent heater cycling compared with smaller volumes
- Tank volume selected to suit typical hydronic liquid heater output and recovery characteristics
- Suitable for use with compatible liquid heater hydronic systems in caravans, RVs and motorhomes
