Common Concerns Answered
Is the thermostat always accurate?
The ignition-protected adjustable thermostat on the Raritan 1700 Series can occasionally require calibration for optimal accuracy. Proper initial setup and periodic checks ensure consistent temperature control.
Does it heat up immediately?
Initial heating from a cold start is most rapid when the engine is operating within its optimal temperature range. If the engine is not fully warmed, the initial heating period may be longer.
Is installation straightforward for a DIYer?
Installation is rated as moderate (3/5) due to the requirement for marine plumbing expertise for both water lines and the engine coolant loop, alongside electrical connections for the 120v element. Professional installation is recommended for those unfamiliar with these systems.
