DH15 System Performance
Time to useable hot water from cold start: 9min
Time to fully hot: 14min
Regeneration time between showers: 7min
Length of shower assuming 30 degree temp rise using Dieselheat shower heads:
Bricor UltraMax 2.5L/min @ 40PSI: >15min
Bricor Elite 4L/min @ 40PSI: 7min
Length of time the system can achieve a 30 deg temperature rise:
2L/min – >15min
3L/min – 13min
4L/min – 6min
5L/min – 3 min
These numbers are all affected by ambient temperature, installation layout and assume no concurrent air heating, so should be taken as a guide.
Ducted Fan Unit Performance
Output: 1.6kW output @ 20 degrees ambient; 1.8kW output @ 10 degrees ambient
Power: less than 2A on high.
Comprehensive Installation Kit
This kit includes all mounting brackets, plug and play wiring looms, coolant pipe (for fan head up to 1m from hot water system), fuel line, exhaust system, coolant fittings etc. needed to install the system and get it up and running. All Dieselheat system also include comprehensive printed installation instructions written by the system creators in simple to understand English to assist first time installers.
