Svans Boiler SV5 Review: Practical hot water for caravans and solar setups?

⚡ At a Glance

• • Heating Performance: Low-pressure 5-litre tank provides hot water for mobile and small systems, compatible with pumps up to 0.5 bar
• • Best for: Caravans, motorhomes, boats and off-grid solar systems needing low-pressure hot water
• • Not ideal for: Properties with high-pressure mains systems or where high-pressure fittings are required

Low-pressure 5-litre tank supplies usable hot water for mobile applications. Thermostat control and full insulation reduce energy loss and standby draw.

Fast warm water – thanks to compact 12 V heater and 5-litre tank

A 5-litre storage vessel combined with the 12 V heating element allows water to reach usable temperature relatively quickly, with hot water available after around 30 minutes. Front-panel temperature control provides a clear set point and indicator lamp during warm-up.

Hot water for washing or a quick shower becomes available within half an hour, convenient when on the move or when relying on limited power sources.

Low energy temperature hold – with full insulation and ECO thermostat

Full insulation around the tank minimises heat loss, while the thermostat cycles the heater off when the set temperature is reached. Maintaining a 65° set point in ECO position draws approximately 0.5-0.8 A per hour.

Keeping water hot uses relatively little power, making the unit suitable for use with leisure batteries or small solar arrays.

Simple integration with caravan plumbing – with low-pressure compatibility up to 0.5 bar

Designed for operation with low-pressure fittings and compatible with foot, hand or small submersible pumps up to a maximum of 0.5 bar. Compact dimensions allow straightforward installation or integration into existing low-pressure systems.

Fits typical caravan and boat plumbing layouts and works with common small pumps, reducing the need for major plumbing alterations.
