Heater installation and maintenance problems – Frequently asked Questions

Installation Questions

Can I install the heater myself?

Yes the kits we offer have been compiled with an owner installation in mind.  The electrical connections have pre-made “plug and play” connectors and the detailed installation manual gives a step by step guide to installation.  At Krueger we personally inspect every installation kit before we send it out to a customer. However installing an air heating system will require numerous holes to be drilled (especially on a boat) and you may feel that our experienced installation engineers are better suited to this.

How much space will a heater installation take up?

The heaters themselves are compact and much of how much space they take up depends on the planning and positioning of the associated components in the installation.  When we carry out an installation ourselves, minimising the impact on your vehicle/boat is paramount and we will position ducting, exhausts and looms securely out of the way as much as possible.

How noisy are the heaters?

The heaters are generally quiet in operation but as with any appliance with moving parts there is some associated noise.  Noise can be reduced to a bare minimum by specifying optional exhaust and air duct silencers on installations.

What are the control options?

Basic controls provide on/off and temperature adjustment with more advanced controls offering 7 day timed programming, diagnostic function and even remote operation from smartphones.

Maintenance Questions

Does my heater require regular servicing?

Servicing intervals generally depend on usage and the environment the heater is operated in. A heavily used heater running on poor quality fuel and in moisture laden conditions will need more attention over time. Generally as an guide to the internal condition of your heater –  if your heater starts and runs without continual smoking (a small amount at start and shutdown is to be expected) it indicates there is good combustion and not excessive carbon build up. More importantly and especially on marine applications is the physical condition of the heater exhaust where breaks or corrosion can lead to unwanted fumes entering the boat in some circumstances.

My heater does not work, what is the most likely fault?

The common faults we see are as a result of insufficient battery voltage and overheating due to lack of coolant or damaged ducting.

When checking and measuring the voltage always check where the main dc positive (red) and negative (brown) connect to the heater making sure the heater is switched on at time of measurement.
