What is the difference in efficiency between plain old ordinary electric heaters and hydronic electric heaters?

I need to replace the electric heaters in a weekend house. Getting new standard electric heaters will cost around $3500 and getting hydronic baseboard heaters will cost around $7500. The people selling the system say that the hydronic heaters will be more efficient since the oil they are filled with stays warm longer than the aluminum radiators of the standard electric baseboards.
I was born at night but not last night and that does not make sense to me: if it takes longer to cool down it will take proportionally longer to heat up. Yeah maybe, says the plumbing guy but alls I know is that the hydronic ones are more efficient so you will make up for your pricier heaters with by using less electricity to heat the house.
We finally wind around to the question: are the electric hydronic heaters more efficient than standard electric baseboard heaters, by roughly how much and, ideally, why?
