Best solution for heating garage/playroom?

[bossychloe]

Hi, I am planning on turning my integral double garage into a playroom but obviously it would need some form of heating.
Does anyone know how difficult and expensive plumbing radiatiors would be compared to the efficiency and expense of using 'electric/convector' heating?

if you've already got a conventional central heating system then extending it into the garage has to be the most economical option in the long run. it all depends on how near to the garage your exisiting pipework is so it can be tapped into and run into the garage.
