The block heater is not made to heat up the engine, but to only warm it up to ensure that it will be easier to start. The inline heater in the radiator hose causes cold water leaks when it's not pluged in as the hose expand and contract, from the different temprature of the hose and the piping used in the inline heater.
If you find that your Suburban is not heating up fast enough after starting it up, replace your thermostat. The OEM thermostat is 195 degrees, as the coolant is constantly circulating from the engine to the heater core and when the temprature get's to 195". The thermostat opens up to allow the coolant to flow towards the radiator and back to the water pump to be circulated in to the engine again. Once the temprature drops below 195", the thermostat closes again and the circulation into the heater core will be at 100% again.
Good luck and keep us posted, i'ld skip on the inline heater.

OEM rated thermostat is 195 degrees, start with that and if you have not flushed out your coolant system. This would be a great tim to get it done, and use http://www.prestone.com/ coolant flush.
This will help the coolant flow thoughout your engine, heater core and radiator which will help extend the life of your water pump.
Good luck and keep us posted.
