For the larger house in a mild ...

For the larger house in a mild climate it may be operated by a boiler or Arcola type of heater.

Where temperatures drop below zero the pipe should be four inches, and heat should be supplied by an oil or coal boiler.

The gravity system is probably not practical for the larger house.

In such circumstances a circulating pump can be used to force the water through the pipe.

The pump must be kept in good condition, for, if it should freeze, water will not circulate and the boiler may explode.

The chimney should be taller than the roof and designed to keep injurious fumes from the house.

Many amateurs use the shed housing their heater as a potting shed.

It is conveniently placed for this purpose and will be warm in winter.

These plans are not for the 'ideal' greenhouse, if there is any such thing.

The ideal, of course, would be three greenhouses.
