 by hot water. If the dwelling is heated by this 

 system, it is a comparatively easy matter to 

 extend the piping to the greenhouse. If there 

 is no way of supplying heat from the house 

 system, and the greenhouse is sixteen by

 one of the small hot-water heaters made for 

 this particular purpose by several firms who
