Dieselheat DH15 Hydronic Hot Water & Heating System | ALPINE Assist
Hot water and cabin warmth — without LPG
Every Alpine Campers model is equipped with the Dieselheat DH15 Hydronic system, delivering fast hot water and optional air heating in one rugged package — ideal for off-grid and cold-weather touring.
How It Works
The DH15 uses a compact diesel furnace (manufactured by Eberspacher) to heat a coolant loop. That hot coolant then:
-
Heats your water supply via a plate heat-exchanger. lifestyleequipment.com.au+1
-
(If fitted) powers a hydronic fan head, delivering warm air into your living space. Dieselheat
Key performance facts:
-
Time to usable hot water: approx. 9-10 minutes from cold start. Dieselheat+1

Frequently Asked Questions
Q. Can I use water instead of coolant for initial testing?
A. Yes — during commissioning you may use water to test the system. But replace with proper coolant before long-term use to avoid corrosion. lifestyleequipment.com.au
Q. What’s the minimum shower flow rate to maximise runtime?
A. For best results we recommend low-flow heads (≈ 2.5 L/min) to stretch hot water capacity. Dieselheat
Q. When should I service it?
A. Preventative servicing is wise — especially if installing in dusty or harsh environments. Clean intake/exhaust and fuel filters regularly. lifestyleequipment.com.au
